  • Using a variable in a mysql query, in a C++ MFC program.

    - by D.Gaughan
    Hi, after extensive trawling of the internet I still havent found any solution for this problem. I`m writing a small C++ app that connects to an online database and outputs the data in a listbox. I need to enable a search function using an edit box, but I cant get the query to work while using a variable. My code is: res = mysql_perform_query (conn, "select distinct artist from Artists"); //res = mysql_perform_query (conn, "select album from Artists where artist = ' ' "); while((row = mysql_fetch_row(res)) != NULL){ CString str; UpdateData(); str = ("%s\n", row[0]); UpdateData(FALSE); m_list_control.AddString(str); } the first "res = " line is working fine, but I need the second one to work. I have a member variable m_search_edit set up for the edit box, but any way I try to include it in the sql statement causes errors. eg. res = mysql_perform_query (conn, "select album from Artists where artist = '"+m_search_edit+" ' "); causes this error: error C2664: 'mysql_perform_query' : cannot convert parameter 2 from 'class CString' to 'char *' No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called" And when I convert m_search_edit to a char* it gives me a " Cannot add 2 pointers" error. Any way around this???

    Can I get some recommendations for good log analysis software for Glassfish log files? Since it will not vary from application server to application server dramatically, I guess that there is a common solution for all servers. Thanks

  • Linq-to-sql Compiled Query is returning result from different DataContext

    - by Vladimir Kojic
    Compiled query: public static Func<OperationalDataContext, short, Machine> QueryMachineById = CompiledQuery.Compile((OperationalDataContext db, short machineID) => db.Machines.Where(m => m.MachineID == machineID).SingleOrDefault()); It looks like compiled query is caching Machine object and returning the same object even if query is called from new DataContext (I’m disposing DataContext in the service but I’m getting Machine from previous DataContext). I use POCOs and XML mapping. Revised: It looks like compiled query is returning result from new data context and it is not using the one that I passed in compiled-query. Therefore I can not reuse returned object and link it to another object obtained from datacontext thru non compiled queries. I’m using unit of work pattern : // First Call Using(new DataContext) { Machine from DataContext.Table == machine from cached query } // Do some work // Second Call is failing Using(new DataContext) { Machine from DataContext.Table <> machine from cached query }

  • C# Entity FrameWork MySQL Slow Queries Count()

    - by Matthew M.
    Hello, I'm having a serious issue with MySQL and Entity Framework 4.0. I have dropped a Table onto the EF Designer surface, and everything seems OK. However, when I perform a query in the following fashion: using(entityContext dc = new entityContext()) { int numRows = dc.myTable.Count(); } The query that is generated looks something like this: SELECT `GroupBy1`.`A1` AS `C1` FROM (SELECT Count(1) AS `A1` FROM (SELECT `pricing table`.`a`, `pricing table`.`b`, `pricing table`.`c`, `pricing table`.`d`, `pricing table`.`e`, `pricing table`.`f`, `pricing table`.`g`, `pricing table`.`h`, `pricing table`.`i` FROM `pricing table` AS `pricing table`) AS `Extent1`) AS `GroupBy1` As should be evident, this is an excruciatingly unoptimized query. It is selecting every single row! This is not optimal, nor is it even possible for me to use MySQL + EF at this point. I have tried both the MySQL 6.3.1 [that was fun to install] and DevArt's dotConnect for MySQL and both produce the same results. This table has 1.5 million records.. and takes 6-11s to execute! What am I doing wrong ? Is there any way to optimize this [and other queries] to produce sane code like: SELECT COUNT(*) FROM table ? Generating the same query using SQLServer takes virtually no time and produces sane code. Help! Thanks! Matthew

  • SQL vs MySQL: Rules about aggregate operations and GROUP BY

    - by Phazyck
    In this book I'm currently reading while following a course on databases, the following example of an illegal query using an aggregate operator is given: Find the name and age of the oldest sailor. Consider the following attempt to answer this query: SELECT S.name, S.age FROM Sailors.S The intent is for this query to return not only the maximum age but also the name of the sailors having that age. However, this query is illegal in SQL--if the SELECT clause uses an aggregate operation, then it must use only aggregate operations unless the query contains a GROUP BY clause! Some time later while doing an exercise using MySQL, I faced a similar problem, and made a mistake similar to the one mentioned. However, MySQL didn't complain and just spit out some tables which later turned out not be what I needed. Is the query above really illegal in SQL, but legal in MySQL, and if so, why is that? In what situation would one need to make such a query?

  • Union - Same table, excluding previous results MySQL

    - by user82302124
    I'm trying to write a query that will: Run a query, give me (x) number of rows (limit 4) If that query didn't give me the 4 I need, run a second query limit 4-(x) and exclude the ids from the first query A third query that acts like the second I have this: (SELECT *, 1 as SORY_QUERY1 FROM xbamZ where state = 'Minnesota' and industry = 'Miscellaneous' and id != '229' limit 4) UNION (SELECT *, 2 FROM xbamZ where state = 'Minnesota' limit 2) UNION (SELECT *, 3 FROM xbamZ where industry = 'Miscellaneous' limit 1) How (or is?) do I do that? Am I close? This query gives me duplicates

  • Alter charset and collation in all columns in all tables in MySQL

    - by The Disintegrator
    I need to execute these statements in all tables for all columns. alter table table_name charset=utf8; alter table table_name alter column column_name charset=utf8; Is it possible to automate this in any way inside MySQL? I would prefer to avoid mysqldump Update: Richard Bronosky showed me the way :-) The query I needed to execute in every table: alter table DBname.DBfield CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci; Crazy query to generate all other queries: SELECT distinct CONCAT( 'alter table ', TABLE_SCHEMA, '.', TABLE_NAME, ' CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;' ) FROM information_schema.COLUMNS WHERE TABLE_SCHEMA = 'DBname'; I only wanted to execute it in one database. It was taking too long to execute all in one pass. It turned out that it was generating one query per field per table. And only one query per table was necessary (distinct to the rescue). Getting the output on a file was how I realized it. How to generate the output to a file: mysql -B -N --user=user --password=secret -e "SELECT distinct CONCAT( 'alter table ', TABLE_SCHEMA, '.', TABLE_NAME, ' CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;' ) FROM information_schema.COLUMNS WHERE TABLE_SCHEMA = 'DBname';" > alter.sql And finally to execute all the queries: mysql --user=user --password=secret < alter.sql Thanks Richard. You're the man!

  • What consequences to take from what i read in logfiles?

    - by Helene Bilbo
    Since some weeks i manage my first Webserver, a Seaside application behind an Apache proxy on Linode, and i installed logwatch to send me daily logs. Where can i get information on when i have to act as a consequence of what i read in these logwatch reports? For example i read that all kinds of people try to login on funny nonexisting accounts or all kinds of webcrawlers test for nonexisting cms login pages, some ip adresses get banned and unbanned by fail2ban... I assume that's normal? Is it? But how do i know that i probably have to do something? What do i look for in the logs?

  • Need help making an ODBC MySQL Connection

    - by Andy Moore
    Short Version: How do I connect from PowerShell to an ODBC 5.1 MySQL Driver? I can't seem to find any connection strings that accurately have a "Provider" field for this particular instance. (See bottom of this question for examples/errors) ===== Long Version: I'm not a server guy, and I've been handed the task of setting up PowerGadgets on our network. I have a MySQL server running on a Linux box, that is configured for remote access and has a user defined for remote access as well. On my windows desktop PC, I have PowerGadgets installed. I installed the MySQL ODBC 5.1 connector, and went to Control Panel Data Sources and set up a User DSN connection to the database. The connection, user, and pass seem to be correct because it lists the tables of the database in my windows control panel. Where I'm running into trouble is in 3 places in PowerGadgets: When selecting a data source, I can select "SQL Server". Inputting the servers IP address does not work and I can't get this option to work at all. When selecting a data source, I can select "OleDB". This screen has a wizard on it, that appears to populate all the correct information (including database table names!) for me. "Test Connection" runs great. But if I try to complete the wizard, I get the error "The .NET Framework data provider for OLEDB does not support the MS Ole DB provider for ODBC Drivers." When selecting a data source, I can select "ODBC". This screen does not have a wizard and I cannot figure out a "connection string" that works. Typically it will respond with the error "The field 'Provider' is missing". Googling ODBC connection strings doesn't reveal any examples with a "provider" field and have no idea what to put in here. The connection string (for #2) above contains "SQLOLEDB" as a provider, and upon inputting that value into this connection string I get the same connection error that #2 gets. I believe I can solve my problems by figuring out a connection string for #3 but don't know where to get started. (PowerGadgets also allows for PowerShell support but I believe I will run into the same problem there) == Here's my current PowerShell connection that doesn't work: invoke-sql -connection "Driver={MySQL ODBC 5.1 Driver};Initial Catalog=hq_live;Data Source=HQDB" -sql "Select * FROM accounts" Spits back the error: "Invoke-Sql : An OLE DB Provider was not specified in the ConnectionString. An example would be, 'Provider=SQLOLEDB;'. == Another string that doesn't work: invoke-sql -connection "Provider=MSDASQL.1;Persist Security Info=False;Data Source=HQDB;Initial Catalog=hq_live" -sql "select * from accounts" And the error: The .Net Framework Data Provider for OLEDB (System.Data.OleDb) does not support the Microsoft OLE DB Provider for ODBC Drivers (MSDASQL). Use the .Net Framework Data Provider for ODBC (System.Data.Odbc).

  • PHP & MySQL on Mac OS X: Access denied for GUI user

    - by Eirik Lillebo
    Hey! This question was first posted to Stack Overflow, but as it is perhaps just as much a server issue I though it might be just as well to post it here also. I have just installed and configured Apache, MySQL, PHP and phpMyAdmin on my Macbook in order to have a local development environment. But after I moved one of my projects over to the local server I get a weird MySQL error from one of my calls to mysql_query(): Access denied for user '_securityagent'@'localhost' (using password: NO) First of all, the query I'm sending to MySQL is all valid, and I've even testet it through phpMyAdmin with perfect result. Secondly, the error message only happens here while I have at least 4 other mysql connections and queries per page. This call to mysql_query() happens at the end of a really long function that handles data for newly created or modified articles. This basically what it does: Collect all the data from article form (title, content, dates, etc..) Validate collected data Connect to database Dynamically build SQL query based on validated article data Send query to database before closing the connection Pretty basic, I know. I did not recognize the username "_securityagent" so after a quick search I came across this from and article at Apple's Developer Connection talking about some random bug: Mac OS X's security infrastructure gets around this problem by running its GUI code as a special user, "_securityagent". Then I tried put a var_dump() on all variables used in the mysql_connect() call, and every time it returns the correct values (where username is not "_securityagent" of course). Thus I'm wondering if anyone has any idea why 'securityagent' is trying to connect to my database - and how I can keep this error from occurring when I call mysql_query(). Update: Here is the exact code I'm using to connect to the database. But a little explanation must follow: The connection error happens at a call to mysql_query() in function X in class_1 class_1 uses class_2 to connect to database class_2 reads a config file with the database connection variables (host, user, pass, db) class_2 connect to the database through the following function: var $SYSTEM_DB_HOST = ""; function connect_db() { // Reads the config file include('system_config.php'); if (!($SYSTEM_DB_HOST == "")) { mysql_connect($SYSTEM_DB_HOST, $SYSTEM_DB_USER, $SYSTEM_DB_PASS); @mysql_select_db($SYSTEM_DB); return true; } else { return false; } }

    This is my first time running a postfixadmin, so in my setup.php, I'm getting this error DEBUG INFORMATION: Invalid query: Unknown column 'create_date' in 'mailbox' I'm running it with MySQL.

My knowledge with mysql and postfix are very minimal btw. Thanks in advance.

  • I/O intensive MySql server on Amazon AWS
