  • PHP - get MySQL query results as their native data type?

    - by redidas
    I've tried fetching MySQL query results using mysql_fetch_row() mysql_result() and numeric values are being returned as strings. Is there any way to fetch the data as its datatype stored in the table? The application will be querying many different queries so I will be unable to cast the values as the intended datatype on a 1 by 1 basis.

  • changing existing duplicate entries in mysql

    - by Mladen
    sorry for the (probably) noob question, but I', new at this stuff. i have a table that has column 'position', and I want to, when inserting a new row, change positions of every row that has position lower than row that is inserted. for example, if I add row with position 4, if there is a duplicate, it should become 5, 5 should shift to 6 and so on... also, is there a way to get highest value for column besides testing it in every row via php?

  • Help with simple query - why isn't an index being used?

    - by Randy Minder
    I have the following query: SELECT MAX([LastModifiedTime]) FROM Workflow There are approximately 400M rows in the Workflow table. There is an index on the LastModifiedTime column as follows: CREATE NONCLUSTERED INDEX [IX_Workflow_LastModifiedTime] ON [dbo].[Workflow] ( [LastModifiedTime] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 100) The above query takes 1.5 minutes to execute. Why wouldn't SQL Server use the above index and simply retrieve the last row in the index to get the maximum value? Thanks.

  • MySQL: how to index an "OR" clause

    - by JoséMi
    I'm executing the following query SELECT COUNT(*) FROM table WHERE field1='value' AND (field2 = 1000 OR field3 = 2000) There is one index over field1 and another composited over field2&field3. I see MySQL always selects the field1 index and then makes a join using the other two fields which is quite bad because it needs to join 146.000 rows. Suggestions on how to improve this? Thanks

  • Change css class depending on label's text

    - by abatishchev
    I have asp:Table with number of asp:Label inside asp:FormView, it represents short stats info. I need to set Label.CssClass to "red" if it's text isn't "0". Currently I do this on FormView.DataBound event. But think that it's better to use JavaScript and probably jQuery. How can I do that?

  • Hibernate reverse engineering

    - by EugeneP
    I have a structure where the main table is USER, other tables include CATEGORY (contains user_id). What I got after the standard reverse engineering procedure was: the class User contained a collection of categories, the class Category didn't contain the foreign key (user_id) but it did contain the User object. Why did it not contain the foreign key as a class property? And how do I join these two tables in HQL without that glue? HQL - please explain this part.

  • “Function” calling inside store procedure

    Hi, I have a big store procedure, that contains a lot of INSERTs. There're many INSERTS that almost identical - they're different by some parameter(s) (all INSERTs to the same table) Is there a way to create a function/method, to which I'll pass the above parameter(s) and the function/method will generate concrete INSERT's? Thanks

  • MySQL - Limit a left join to the first date-time that occurs?

    - by John M
    Simplified table structure (the tables can't be merged at this time): TableA: dts_received (datetime) dts_completed (datetime) task_a (varchar) TableB: dts_started (datetime) task_b (varchar) What I would like to do is determine how long a task took to complete. The join parameter would be something like ON task_a = task_b AND dts_completed < dts_started The issue is that there may be multiple date-times that occur after the dts_completed. How do I create a join that only returns the first tableB-datetime that occurs after the tableA-datetime?

  • indentationLevel property doesn't appear to do anything?

    - by JoBu1324
    I'm have a number rows I'm inserting into a table using -insertRowsAtIndexPaths:withRowAnimation, and I would like the rows to be indented from the left to distinguish them from the rest of the cells. The indentationLevel property of UITableViewCell looks like it's exactly what I need, but it doesn't seem to do anything. Here's the code I'm using to set the indentation level (dot syntax doesn't make a difference): [cell setIndentationWidth:10]; [cell setIndentationLevel:1]; Is indentationLevel what I want, or should I be looking elsewhere?

  • Python templates for huge HTML/XML

    - by newtover
    Hello, Recently I needed to generate a huge HTML page containing a report with several thousand row table. And, obviously, I did not want to build the whole HTML (or the underlying tree) in memory. As result, I built the page with the old good string interpolation, but I do not like the solution. Thus, I wonder whether there are Python templating engines that can yield resulting page content by parts.
