    - by Blankman
    using this as a guide: http://msdn.microsoft.com/en-us/library/dd250846.aspx can someone help me with the jquery call? Do I actually pass in the javascript code for the callback, or just the name of the function? BingSearch = function($bingUrl, $bingAppID, $keyword, $callBack) { $bingUrl = $bingUrl + "?JsonType=callback&JsonCallback=" + $callBack + "&Appid=" + $bingAppID + "&query=" + encodeURI($keyword) + "&sources=web"; $.ajax({ dataType: 'jsonp', jsonp: $callBack, url: $bingUrl, success: function(data) { alert('success'); $callBack(data); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert("error: " + textStatus); } }); };

  • Ora-01000 - maximum open cursors exceeded error

    - by PeteDaMeat
    I am receiving the following error message within my Delphi/Oracle application "ora-01000 - maximum open cursors exceeded". The code is as follows: begin for i := 0 to 150 do begin with myADOQuery do begin SQL.Text := 'DELETE FROM SOMETABLE'; ExecSQL; -- from looking at V$OPEN_CURSOR a new cursor is added on each iteration for the session Close; -- thought this would close the cursor but doesn't end; end; end; I'm aware I can resolve the problem by simply increasing the number of OPEN_CURSORS parameters, however, I would rather find a solution whereby the cursor is closed after the query is executed. Any ideas? Delphi 2006 BDS Oracle 10g

  • MySQL dual license behavior

    - by jromero
    Hi SO, I'm running a commercial(closed source) Web App development for the first time. Initially I considered MySQL the most feasible option for a DB, until I get quite confused about its dual license behavior. If I want a commercial application do I still can use the GPL version of MySQL or I must get a license? The same question in a different way: If I use MySQL's GPL version does that force me to license the whole app under GPL? Either case I would go with PostgreSQL, I just want to make really really sure about this. Even in SO I've seen related("duplicates") questions but never a clear answer... All other tools I'm gonna use to code the project are licensed under BSD or MIT. Just in case, the role of MySQL in the project is merely as relational DB to store persistent data and query it. I'd really appreciate if someone can clarify this for me. Regards, thanks in advanced.

  • How important is caching for a site's speed with PHP?

    - by benhowdle89
    I've just made a user-content orientated website http://www.humanisms.co.uk Its done in PHP, MySQL and jQuery's AJAX, at the moment there is only a dozen or so submissions and already i can feel it lagging slightly when it goes to a new page (therefore running a new mysql query) Is it most important for me to try and optimise my mysql queries (by prepared statements) or is it worth in looking at CDN's (amazon s3) and caching (much like the WordPress plugin WP Super Cache) which works by serving static HTML files when there hasnt been new content submitted. Which route is the most beneficial, for me as a developer, to take, ie. where am i better off concentrating my efforts to speed up the site?

  • SQL Operators as text in where clause

    - by suggy1982
    I have the following table, which is used for storing bandings. The table is maintained via a web frontend. CREATE TABLE [dbo].[Banding]( [BandingID] [int] IDENTITY(1,1) NOT NULL, [ValueLowerLimitOperator] [varchar](10) NULL, [ValueLowerLimit] [decimal](9, 2) NULL, [ValueUpperLimitOperator] [varchar](10) NULL, [ValueUpperLimit] [decimal](9, 2) NULL, [VolumeLowerLimitOperator] [varchar](10) NULL The operator fields store values such as < = <=. I want to get to a position where I can use the operators values stored in the table in a case statement in a where clause. Like this. SELECT * FROM table WHERE CASE ValueLowerLimitOperator WHEN '<' THEN VALUE < X WHEN '>' THEN VALUE > X END rather than having to write mutiple case or if statements for each permutation. Does anyone have any suggestions how I can decode the operators values stored in the table as part of my query and then use them in a case/where statement?

  • Django/Python: Save an HTML table to Excel

    - by kchau
    I have an HTML table that I'd like to be able to export to an Excel file. I already have an option to export the table into an IQY file, but I'd prefer something that didn't allow the user to refresh the data via Excel. I just want a feature that takes a snapshot of the table at the time the user clicks the link/button. I'd prefer it if the feature was a link/button on the HTML page that allows the user to save the query results displayed in the table. Is there a way to do this at all? Or, something I can modify with the IQY? I can try to provide more details if needed. Thanks in advance.

  • php mysql database users connection handling

    - by aviv
    What is the best way to handle mysql database users connection in PHP? I have a web server running a PHP application on MySQL. I have created a database user for the application: dbuser1 with limited access - only for query, insert and update tables. No alter table. Now the question is, should i use the same dbuser1 widely in my scripts, so if there are 100 current people using my system and hence 100 scripts running parallel they all connect to the database with the same dbuser1? or should i create a few users and assign each script a different user or load-balance between the dbusers ?

    I've huge a table (a few billion rows) with a clustered index and two non-clustered indices. A BULK INSERT operation produces 112000 reads and only 383 writes (duration 19948ms).

  • Expression.OrElse, dynamically creating a condition.

    - by Jim
    Hi, I am attempting to create a dynamic where clause using the standard expression API. var query = ( from p in Parties orderby p.PartyId orderby p.FullName select p ).AsQueryable(); Expression<Func<Party, bool>> @fn = (p) => SqlMethods.Like(p.FullName, "%smith%") || SqlMethods.Like(p.Person.FirstName, "%smith%"); Expression<Func<Party, bool>> @sn = (p) => SqlMethods.Like(p.Person.FirstName, words[0]); ParameterExpression pe = Expression.Parameter(typeof(Party), "p"); Expression orelse = Expression.OrElse( Expression.Lambda(@fn, pe), Expression.Lambda(@sn, pe) ); The expressions above will ultimately be added to a where clause. I need to add a bunch of 'likes'. How do I do this? I get InvalidOperationException on the operator OrElse I have also tried Expression.Or Thanks Regards Craig.

  • PL/SQL Package invalidated

    - by FrustratedWithFormsDesigner
    I have a script that makes use of a package (PKG_MY_PACKAGE). I will change some of the fields in a query in that package and then recompile it (I don't change or compile any other packages). I run the script and I get an error that looks like ORA-04068: existing state of packages has been discarded ORA-04061: existing state of package body "USER3.PKG_MY_PACKAGE" has been invalidated ORA-04065: not executed, altered or dropped package body "USER3.PKG_MY_PACKAGE" ORA-06508: PL/SQL: could not find program unit being called: "USER3.PKG_MY_PACKAGE" ORA-06512: at line 34 I run the script again (without changing anything else in the system) and the script executes successfully. I thought that when I compiled before I executed the script that would fix any invalid references. This is 100% reproducible, and the more I test this script the more annoying it gets. What could cause this, and what would fix it? (oracle 10g, using PL/SQL Developer 7)

  • How to merge data from two separate access 2007 databases

    - by DiegoMaK
    Hi, I have two identical databases with same structure, database a in computer a and database b in computer b. The data of database a*(a.accdb)* and database b*(b.accdb)* are different. then in database a i have for example ID:1, 2, 3 and in database B i Have ID:4,5,6 Then i need merge these databases data in only one database(a or b, doesn't matter) so the final database looks like. ID:1,2,3,4,5,6 I search an easy way to do this. because i have many tables. and do this by union query is so tedious. I search for example for a backup option for only data without scheme as in postgreSQl or many others RDBMS, but i don't see this options in access 2007. pd:only just table could be have duplicate values(I guess that pk doesn't allow copy a duplicate value and all others values will be copied well). if i wrong please correct me. thanks for your help.

  • SQL Group By equivalent

    - by MikeB
    Pretend I have a cupcake_rating table: id | cupcake | delicious_rating -------------------------------------------- 1 | Strawberry | Super Delicious 2 | Strawberry | Mouth Heaven 3 | Blueberry | Godly 4 | Blueberry | Super Delicious I want to find all the cupcakes that have a 'Super Delicious' AND 'Mouth Heaven' rating. I feel like this is easily achievable using a group by clause and maybe a having. I was thinking: select distinct(cupcake) from cupcake_rating group by cupcake having delicious_rating in ('Super Delicious', 'Mouth Heaven') I know I can't have two separate AND statements. I was able to achieve my goal using: select distinct(cupcake) from cupcake_rating where cupcake in ( select cupcake from cupcake_rating where delicious_rating = 'Super Delicious' ) and cupcake in ( select cupcake from cupcake_rating where delicious_rating = 'Mouth Heaven' ) This will not be satisfactory because once I add a third type of rating I am looking for, the query will take hours (there are a lot of cupcake ratings).

  • Convert object to DateRange

    - by user655832
    I'm querying an underlying PostgreSQL database using Pandas 0.8. Pandas is returning the DataFrame properly but the underlying timestamp column in my database is being returned as a generic "object" type in Pandas. As I would eventually like to seasonal normalization of my data I am curious as to how to convert this generic "object" column to something that is appropriate for analysis. Here is my current code to retrieve the data: # get records from db example import pandas.io.sql as psql import psycopg2 # define query to get all subs created this year QRY = """ select i i, i * random() f, case when random() > 0.5 then true else false end t, (current_date - (i*random())::int)::timestamp with time zone tsz from generate_series(1,1000) as s(i) order by 4 ; """ CONN_STRING = "host='localhost' port=5432 dbname='postgres' user='postgres'" # connect to db conn = psycopg2.connect(CONN_STRING) # get some data set index on relid column df = psql.frame_query(QRY, con=conn) print "Row count retrieved: %i" % (len(df),) Thanks for any help you can render.

  • How to use SMS content provider? Where are the docs?

    - by Mark
    Hi, I'd like to be able to read the system's SMS content provider. Basically I wanted to make an SMS messaging app, but it would only be useful if I could see past threads etc. It seems like there's a content provider for this, but I can't find documentation for it - anyone know where that is? Thanks -------- edit ----------- Ok I found a way to get the sms inbox provider, and I just dumped all the column names in that provider, looks like this: Uri uriSms = Uri.parse("content://sms/inbox"); Cursor c = context.getContentResolver().query(uriSms, null,null,null,null); // column names for above provider: 0: _id 1: thread_id 2: address 3: person 4: date 5: protocol 6: read 7: status 8: type 9: reply_path_present 10: subject 11: body 12: service_center 13: locked I'm just piecing this together from random threads I find around the net, I'm really wondering where this is all documented (if at all)? Thanks again

  • Syntax error converting the nvarchar value to a column of data type int.

    - by Phil
    I have 1,2,3,4,5,6,7,8,9 stored as nvarchar inside Level in my db. I then have a dropdownlist with values 1,2,3,4,5,6,7,8,9. When a user makes a selection (i.e 1) (Level.SelectedValue.ToString). This builds an sql query via a param like this: "Select things From MBA_EOI Where level = 1" When I run the select I get the following error: Syntax error converting the nvarchar value '1,2,3,4,5,6,7,8,9' to a column of data type int. I was under the impression that I was dealing with an Nvarchar field and the selected value as string, where does the int conversion come in? p.s I have also tried Level.SelectedItem.ToString

  • Entity Framework How to specify paramter type in generated SQL (SQLServer 2005) Nvarchar vs Varchar

    - by Gratzy
    In entity framework I have an Entity 'Client' that was generated from a database. There is a property called 'Account' it is defined in the storage model as: <Property Name="Account" Type="char" Nullable="false" MaxLength="6" /> And in the Conceptual Model as: <Property Name="Account" Type="String" Nullable="false" /> When select statements are generated using a variable for Account i.e. where m.Account == myAccount... Entity Framework generates a paramaterized query with a paramater of type NVarchar(6). The problem is that the column in the table is data type of char(6). When this is executed there is a large performance hit because of the data type difference. Account is an index on the table and instead of using the index I believe an Index scan is done. Anyone know how to force EF to not use Unicode for the paramater and use Varchar(6) instead?

  • End User Ad-Hoc Reporting Tool: Microsoft SQL Server Management Studio or Microsoft Access?

    - by schultkl
    Our centralized IT department has suggested two primary ad hoc query tools for our general user base of approximately 200 staff members: Microsoft SQL Server Management Studio 2008 (SSMS) Microsoft Access 2003 Environment The backend database is a read-only Microsoft SQL Server 2005 database. The schema is 400+ tables; allowing access to the raw data for our general staff would be a disaster. We will be building an "abstraction layer" over the raw data for our general staff to run ad hoc queries against. The abstraction layer will most likely contain a number of views. A number of users have basic knowledge in Microsoft Access; none have used SSMS. Which of the above tools (or alternative) would be best for a decidedly non-techie user base of approximately 200 people? What are the pros and cons of each? Also, the IT department has suggested teaching people T-SQL so they may use SSMS. Is this reasonable?

  • Dynamically changing background color of specific text without changing other attributes

    - by gsingh2011
    I've written a chrome extension to find text on a page based on a regex query. When text is matched, I wrap the matched text in a <span> tag that has the class highlight where highlight only changes the background color to yellow. The issue is that sometimes there are already styles applied to <span> tags in a webpage. For example, the webpage might have this defined: span { font-size: 200%; } So when I insert my <span> tag in another <span> tag, the font-size is actually 400%. Is there an easy way for my code to just change certain properties of the text, like the background color, without applying the webpage's styles twice?
