  • Is there a way to rollback and exit a psql script on error?

    - by metanaito
    I have a psql script that looks like this: -- first set of statements begin sql statement; sql statement; sql statement; exception when others then rollback write some output (here I want to exit the entire script and not continue on to the next set of statements) end / -- another set of statements begin sql statement; sql statement; sql statement; exception when others then rollback write some output (here I want to exit the entire script and not continue) end / ... and so on Is it possible to exit the script and stop processing the rest of the script?

  • php database session handling problem in IE8!

    - by psyb0rg
    I've got an html page from where Im making this call periodically: function logon(id) { $.get("data.php", { action: 'online', userID: id}, function(data){ $("#msg").html(data); }); } What this does is it calls this SQL script in data.php: $sql = "update user_sessions set expires=(expires + 2) where userID = $userID"; mysql_query($sql, $conn) or die(mysql_error()); echo $sql; I can see by the echo that the sql syntax and values are correct, but THE CHANGES TO THE expires FIELD ARE NOT DONE, ONLY IN IE8!! It works fine in other ff, safari, chrome, ie6 and 7. There is nothing browser specific about making this sql call, but the user_sessions table is used to store PHP's sessions. Im only increasing the session expiry time when the call is made. What in IE8's session handling is preventing the session time from changing? Is there any caching or cookie problem that needs to be changed?

  • Update Statement Updates 0 Rows via the C# Winform Application?

    - by peace
    First of all, please help me out! I can not take this anymore. I could not find where the error is located. Here is my problem: I'm trying to update a row via c# winform application. The update query generated from the application is formatted correctly. I tested it in the sql server environment, it worked well. When i run it from the application i get 0 rows updated. Here is the snippet that generates the update statement using reflection - don't try to figure it out. Carry on reading after the code portion: public void Update(int cusID) { SqlCommand objSqlCommand = new SqlCommand(); Customer cust = new Customer(); string SQL = null; try { if ((cusID != 0)) { foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { if (!(PropertyItem.Name.ToString() == cust.PKName)) { if (PropertyItem.Name.ToString() != "TableName") { if (SQL == null) { SQL = PropertyItem.Name.ToString() + " = @" + PropertyItem.Name.ToString(); } else { SQL = SQL + ", " + PropertyItem.Name.ToString() + " = @" + PropertyItem.Name.ToString(); } } else { break; } } } objSqlCommand.CommandText = "UPDATE " + this.TableName + " SET " + SQL + " WHERE " + cust.PKName + " = @cusID AND PhoneNumber = " + "'" + "@phNum" + "'"; foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { if (!(PropertyItem.Name.ToString() == cust.PKName)) { if (PropertyItem.Name.ToString() != "TableName") { objSqlCommand.Parameters.AddWithValue("@" + PropertyItem.Name.ToString(), PropertyItem.GetValue(this, null)); } else { break; } } } objSqlCommand.Parameters.AddWithValue("@cusID", cusID); objSqlCommand.Parameters.AddWithValue("@phNum", this.PhoneNumber); DAL.ExecuteSQL(objSqlCommand); } else { //AppEventLog.AddWarning("Primary Key is not provided for Update.") } } catch (Exception ex) { //AppEventLog.AddError(ex.Message.ToString) } } This part below: objSqlCommand.CommandText = "UPDATE " + this.TableName + " SET " + SQL + " WHERE " + cust.PKName + " = @cusID AND PhoneNumber = " + "'" + "@phNum" + "'"; generates dml: UPDATE CustomerPhone SET PhoneTypeID = @PhoneTypeID, PhoneNumber = @PhoneNumber WHERE CustomerID = @cusID AND PhoneNumber = '@phNum' @PhoneTypeID and @PhoneNumber are gotten from two properties. We assigned the value to these properties in the presentation layer from the user input text box. The portion below where fetches the values: objSqlCommand.Parameters.AddWithValue("@" + PropertyItem.Name.ToString(), PropertyItem.GetValue(this, null)); The code below fills the values of WHERE: objSqlCommand.Parameters.AddWithValue("@cusID", cusID); objSqlCommand.Parameters.AddWithValue("@phNum", this.PhoneNumber); The final code should look as: UPDATE CustomerPhone SET PhoneTypeID = 7, PhoneNumber = 999444 WHERE CustomerID = 500 AND PhoneNumber = '911'; Phone type id is 7 - user value that is taken from text box Phone number is 999444 - user value that is taken from text box The above final update statement works on the sql environment, but when running via the application, the execute non query runs ok and gets 0 rows updated! I wonder why?

  • Should I upgrade to "Ubuntu 14.04 'Trusty Tahr'" from "Ubuntu 12.04 LTS" and what care do I need to take if I upgrade?

    - by PHPLover
    I'm basically a Web Developer(PHP Developer) by profession. I mainly work on PHP, jQuery, AJAX, Smarty, HTML and CSS, Bootstrap front-end web development framework. I've also installed and using IDEs/editors like Sublime Text, NetBeans. I'm also using Git repository for my website development as a versioning tool. I'm using "Ubuntu 12.04 LTS" on my machine almost since last two years. My machine configuraion is as follows: Memory : 3.7 GiB Processor : Intel® Core™ i3 CPU M 370 @ 2.40GHz × 4 Graphics : Unknown OS type : 64-bit Disk : 64-bit The important softwares present on my machine and which I'm using daily for my work are as follows: PHP : PHP 5.3.10-1ubuntu3.13 with Suhosin-Patch (cli) (built: Jul 7 2014 18:54:55) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies Apache web server : /usr/sbin/apachectl: 87: ulimit: error setting limit (Operation not permitted) Server version: Apache/2.2.22 (Ubuntu) Server built: Jul 22 2014 14:35:25 Server's Module Magic Number: 20051115:30 Server loaded: APR 1.4.6, APR-Util 1.3.12 Compiled using: APR 1.4.6, APR-Util 1.3.12 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/etc/apache2" -D SUEXEC_BIN="/usr/lib/apache2/suexec" -D DEFAULT_PIDLOG="/var/run/apache2.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="/var/run/apache2/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="mime.types" -D SERVER_CONFIG_FILE="apache2.conf" MySQL : 5.5.38-0ubuntu0.12.04.1 Smarty : 2.6.18 **NetBeans :** NetBeans IDE 8.0 (Build 201403101706) Sublime Text 2 : Version 2.0.2, Build 2221 Yesterday suddenly a pop-up message appeared on my screen asking me to upgrade to "Ubuntu 14.04 'Trusty Tahr'". I'd also be very happy to upgrade my system to "Ubuntu 14.04 'Trusty Tahr'". Following are the issues about which I'm little bit scared about and I need you all talented people's expert advice/help/suggestions on it: Will upgrading to "Ubuntu 14.04 'Trusty Tahr'" affect the softwares I mentioned above? I mean will I need to re-install/un-install and install these softwares too? Do I really need to and is it really a worth to upgrade to "Ubuntu 14.04 'Trusty Tahr'" from "Ubuntu 12.04 LTS" now? If I upgrade to "Ubuntu 14.04 'Trusty Tahr'" what advantage I'll get from web developer's point of view? Will the upgrade be hassle free and will I be ablr to continue my on-going work without any difficulties? Is "Ubuntu 14.04 'Trusty Tahr'" a LTS version and if yes till when it's going to provide support? These are the five crucial queries I have. If you want any further explanation from me please feel free to ask me. Thanks for spending some of your vaulable time in reading and understanding my issue. Any kind of help/comment/suggestion/answer would be highly appreciated. Though if someone gives canonical, precise and up to the mark answer, it will be of great help to me as well as other web developers using Ubuntu around the world. Once again thank you so much you great people around the globe. Waiting for your precious replies.

  • PASS Summit 2011 &ndash; Part III

    - by Tara Kizer
    Well we’re about a month past PASS Summit 2011, and yet I haven’t finished blogging my notes! Between work and home life, I haven’t been able to come up for air in a bit.  Now on to my notes… On Thursday of the PASS Summit 2011, I attended Klaus Aschenbrenner’s (blog|twitter) “Advanced SQL Server 2008 Troubleshooting”, Joe Webb’s (blog|twitter) “SQL Server Locking & Blocking Made Simple”, Kalen Delaney’s (blog|twitter) “What Happened? Exploring the Plan Cache”, and Paul Randal’s (blog|twitter) “More DBA Mythbusters”.  I think my head grew two times in size from the Thursday sessions.  Just WOW! I took a ton of notes in Klaus' session.  He took a deep dive into how to troubleshoot performance problems.  Here is how he goes about solving a performance problem: Start by checking the wait stats DMV System health Memory issues I/O issues I normally start with blocking and then hit the wait stats.  Here’s the wait stat query (Paul Randal’s) that I use when working on a performance problem.  He highlighted a few waits to be aware of such as WRITELOG (indicates IO subsystem problem), SOS_SCHEDULER_YIELD (indicates CPU problem), and PAGEIOLATCH_XX (indicates an IO subsystem problem or a buffer pool problem).  Regarding memory issues, Klaus recommended that as a bare minimum, one should set the “max server memory (MB)” in sp_configure to 2GB or 10% reserved for the OS (whichever comes first).  This is just a starting point though! Regarding I/O issues, Klaus talked about disk partition alignment, which can improve SQL I/O performance by up to 100%.  You should use 64kb for NTFS cluster, and it’s automatic in Windows 2008 R2. Joe’s locking and blocking presentation was a good session to really clear up the fog in my mind about locking.  One takeaway that I had no idea could be done was that you can set a timeout in T-SQL code view LOCK_TIMEOUT.  If you do this via the application, you should trap error 1222. Kalen’s session went into execution plans.  The minimum size of a plan is 24k.  This adds up fast especially if you have a lot of plans that don’t get reused much.  You can use sys.dm_exec_cached_plans to check how often a plan is being reused by checking the usecounts column.  She said that we can use DBCC FLUSHPROCINDB to clear out the stored procedure cache for a specific database.  I didn’t know we had this available, so this was great to hear.  This will be less intrusive when an emergency comes up where I’ve needed to run DBCC FREEPROCCACHE. Kalen said one should enable “optimize for ad hoc workloads” if you have an adhoc loc.  This stores only a 300-byte stub of the first plan, and if it gets run again, it’ll store the whole thing.  This helps with plan cache bloat.  I have a lot of systems that use prepared statements, and Kalen says we simulate those calls by using sp_executesql.  Cool! Paul did a series of posts last year to debunk various myths and misconceptions around SQL Server.  He continues to debunk things via “DBA Mythbusters”.  You can get a PDF of a bunch of these here.  One of the myths he went over is the number of tempdb data files that you should have.  Back in 2000, the recommendation was to have as many tempdb data files as there are CPU cores on your server.  This no longer holds true due to the numerous cores we have on our servers.  Paul says you should start out with 1/4 to 1/2 the number of cores and work your way up from there.  BUT!  Paul likes what Bob Ward (twitter) says on this topic: 8 or less cores –> set number of files equal to the number of cores Greater than 8 cores –> start with 8 files and increase in blocks of 4 One common myth out there is to set your MAXDOP to 1 for an OLTP workload with high CXPACKET waits.  Instead of that, dig deeper first.  Look for missing indexes, out-of-date statistics, increase the “cost threshold for parallelism” setting, and perhaps set MAXDOP at the query level.  Paul stressed that you should not plan a backup strategy but instead plan a restore strategy.  What are your recoverability requirements?  Once you know that, now plan out your backups. As Paul always does, he talked about DBCC CHECKDB.  He said how fabulous it is.  I didn’t want to interrupt the presentation, so after his session had ended, I asked Paul about the need to run DBCC CHECKDB on your mirror systems.  You could have data corruption occur at the mirror and not at the principal server.  If you aren’t checking for data corruption on your mirror systems, you could be failing over to a corrupt database in the case of a disaster or even a planned failover.  You can’t run DBCC CHECKDB against the mirrored database, but you can run it against a snapshot off the mirrored database.

  • Django: making raw SQL query, passing multiple/repeated params?

    - by AP257
    Hopefully this should be a fairly straightforward question, I just don't know enough about Python and Django to answer it. I've got a raw SQL query in Django that takes six different parameters, the first two of which (centreLat and centreLng) are each repeated: query = "SELECT units, (SQRT(((lat-%s)*(lat-%s)) + ((lng-%s)*(lng-%s)))) AS distance FROM places WHERE lat<%s AND lat>%s AND lon<%s AND lon>%s ORDER BY distance;" params = [centreLat,centreLng,swLat,neLat,swLng,neLng] places = Place.objects.raw(query, params) How do I structure the params object and the query string so they know which parameters to repeat and where?

  • T-Sql Modify Insert SProc To Update If Exists.

    Scenario I have a stored procedure written in T-Sql that I use to insert data into a table as XML. Since the data gets updated regularly, I want the rows to be updated if they already exist (Aside from when the application is first run, they will always exist).

  • How to capture input parameters from within stored procedure (SQL Server 2005)?

    - by Duncan
    I would like to create a generic logging solution for my stored procedures, allowing me to log the values of input parameters. Currently I am doing this more or less by hand and I am very unhappy with this approach. Ideally, I would like to say something like the following: "given my spid, what are my input parameters and their values?" This is the same information exposed to me when I run SQL Profiler -- the stored procedure's name, all input params and all input VALUES are listed for me. How can I get my hands on these values from within a stored procedure? Thanks; Duncan

  • bi-directional o2m/m2o beats uni-directional o2m in SQL efficiency?

    - by Henry
    Use these 2 persistent CFCs for example: // Cat.cfc component persistent="true" { property name="id" fieldtype="id" generator="native"; property name="name"; } // Owner.cfc component persistent="true" { property name="id" fieldtype="id" generator="native"; property name="cats" type="array" fieldtype="one-to-many" cfc="cat" cascade="all"; } When one-to-many (unidirectional) Note: inverse=true on unidirectional will yield undesired result: insert into cat (name) values (?) insert into Owner default values update cat set Owner_id=? where id=? When one-to-many/many-to-one (bi-directional, inverse=true on Owner.cats): insert into Owner default values insert into cat (name, ownerId) values (?, ?) Does that mean setting up bi-directional o2m/m2o relationship is preferred 'cause the SQL for inserting the entities is more efficient?

  • Does SQL Server Compact Edition (SqlCe) have a SNAPSHOT table like Oracle Lite?

    - by MusiGenesis
    In Oracle Lite, you can create a SNAPSHOT table which is like a normal table except that it tracks changes to itself. The syntax is CREATE SNAPSHOT TABLE tblWhatever ... and you can perform CRUD operations on it like a normal table. To get the change information, you query the table like this: SELECT * FROM tblWhatever + WHERE ... which returns all the rows in the table (including deleted ones) meeting the WHERE clause, and you can access each row's row_state column as a normal field (which is invisible to a normal SELECT * FROM tblWhatever WHERE ... query). Is there some way to do the same thing with Sql Compact Edition (3.5) - i.e. create a table that tracks changes without using RDA?

  • Erlang Mnesia Equivalent of SQL Select FROM WHERE Field IN (value1, value2, value3, ...)

    - by ErJab
    I have an mnesia table with fields say f1, f2, f3. Now if I were to select all the rows with the field value as V1, I would use mnesia:select and match specifications or a simple mnesia:match_object. Now I need to select all the rows which have V1, V2, V3 ... or Vn (a list of arbitrary length) as the value for field f1. In SQL I would do something like SELECT * FROM tablename WHERE f3 IN (V1, V2, V3, ... , Vn) How do I do this in mnesia?

  • What are good educational resources for setting up .Net Webservice on a DMZ connecting to SQL Server

    - by Brian
    We are going to begin implementing a web service that will be hosted on a DMZ server. This web server will post data to a SQL server and we're trying to determine the best methodology to handle this. Things that concern us are web service authentication, SOAP, and whether or not to store the database on the DMZ or the local network. This same scenario will apply to ASP.Net apps. Trust me, I've already searched the web, but as usual, the online resources I've found either talk about just authentication, or just about SOAP, or etc, but does not show or suggest how the entire system can work together. Can you give me a list of resources such as links that I've missed, books, classes, or etc that would help? Thank You.

  • Is there a more expressive way of executing SQL query using Qt?

    - by ShaChris23
    I currently have this code: // Construct query QString const statement = QString("drop database if exists %1") .arg(databaseName_); QSqlQuery query(db); query.exec(statement); Is there a better way to code than the above? Specifically, I dont like how I use QString for SQL statement. It'd be nice if Qt has some class so that I could do something like: // Construct query QSomeClass statement = "drop database if exists %1"; statement.setArg(1, databaseName_); // Replace all %1 in the original string. QSqlQuery query(db); query.exec(statement);

    Given a set of delimited data in the following format: 1|Star Wars: Episode IV - A New Hope|1977|Action,Sci-Fi|George Lucas 2|Titanic|1997|Drama,History,Romance|James Cameron How can I generate sql insert statements in this format? insert into table values(1,"Star Wars: Episode IV - A New Hope",1977","Action,Sci-Fi","George Lucas",0); insert into table values(2,"Titanic",1997,"Drama,History,Romance","James Cameron",0); To simplify the problem, let's allow for a parameter to tell which columns are text or numeric. (e.g. 0,1,0,1,1)

  • Retrieve entities with children per one sql call. ADO.NET Entity framework

    - by Andrew Florko
    Hello everybody, I have two tables: A & B B { B1: Field1, B2: Field2, ... } A { Children: List of B, A1: Field1, A2: Field2, } I want to retrieve "A" entities with related "B" entities like this: DataContext.A.Select( a = new MySubset( A1 = a.A1, Children = a.Children.Select(b = b.B1).ToList()); But EF can't translate ToList into SQL, so i have to call ToList() per each instance in query producing additional network call. How can I avoid this? Thank you in advance.
