Bit of a complicated SQL question here. I currently have a SELECT statement which matches several fields, like this. SELECT field1, field2, field3, field4, field5 FROM table WHERE field1 = 'variable 1' AND field2 = 'variable 2' AND field3 = 'variable 3' AND field4 = 'variable 4' AND field5 = 'variable 5' I would like to modify t...
I have a deadlock problem with two transactions that do not access any common records. There is also no lock escalation. So I can't explain why a deadlock is possible. The deadlock occurs when two such transactions are executed at the same time: begin transaction update A set [value] = [value] where id = 1; /* resp. 2 */ /* synchroni...
I have a page that contains a Gridview showing a record from a db table e.g. "tblEmployee". If a record is inserted/updated/deleted in that table then I need my page to be reloaded so that the gridview will show the updated records. Records may be inserted/updated/deleted from any other application. To rebind the gridview I have to relo...
I'm seeing a huge performance hit in our enterprise application when changing the XML schema collection of a given column on a large table. Simplistically put, we're doing something like this: ALTER TABLE HugeTable ALTER COLUMN CustomFields XML (note: CustomFields was previously bound to XML(CustomFieldsSchemaCollection, but of course...

I know I can do this with a CTE or another means but I am wondering if this can be done in one select query (no sub-selects). I want to find the most recent crt_ts for the po_nbr and then take the associated id. Note: The id column is not guaranteed to be sequential, I simplified it for this question. Code: create table temp ( ...
Im using SQL Server 2005 . I have 2 WITH Clauses in my stored procedure WITH SomeClause1 AS ( SELECT .... ) WITH SomeClause2 AS ( SELECT .... ) But the error occurs Incorrect syntax near the keyword 'with'.

I know how to get in SQL (SQL Server) the current date, but with the beginning of the day: select dateadd(DAY, datediff(day, 0, getdate()),0) (result:2009-09-17 00:00:00.000) I need to get (in SQL) the current date with the beginning of this hour. For example: 2009-09-17 17:00:00 (I don't care about the exact format) and I need to g...
Sorry for the long question but this contains all the SQL I've used to test the scenario to hopefully make it clear as to what I'm doing. I'm build up some dynamic SQL to produce a PIVOT table in SQL Server 2005. Below is code to do this. With various selects showing the raw data the values using GROUP BY and the values in a PIVOT as I...
How can I find out if an instance of SQL Server 2005 allows case sensitive databases or not? By case sensitive, I mean case sensitivity of the objects in the database, i.e. the following two statements are not equivalent: SELECT * FROM TABLE SELECT * FROM table I've looked in the property pages of the server (in Management Studio) bu...
I have a Windows Forms application with a DataSet (.xsd) that is currently set to connect to a Sql Ce database. Compact Edition is being used so the users can use this application in the field without an internet connection, and then sync their data at day's end. I have been given a new project to create a supplemental web interface for...
Greetings. I have a SSRS 2005 report that shows prices of things. For some customers, I hide a column from the table (with an expression on the Visibility - hidden property). When I do this, my table shrinks. I've searched long and hard for a way to dynamically resize this table (or to do something at design time to make it stay the ...
If I have the following SQL: BEGIN TRANSACTION SELECT val FROM myTable and don't follow it up with a commit, what happens with the TRANSACTION? Does it depend upon the context/scope that it was executed (e.g. in a proc, in mgt studio)? Is there some place to see if there are transactions open that have not been committed/rolled back ...
I'm putting together a database of locations for looking up nearest locations for a given address. As I started laying out the table going about my business I wondered what other people were doing and if there was a 'best practices' for some common datatypes. Such as phone numbers, addresses and even latitude and longitude. This is wha...
I am working on implementing an SSIS package in SQL Server 2005 which deals with XML files. Multiple XML files will be read-in from a directory on the file system and data from each XML file will be imported into a database table. The XML to database row works fine and I can iterate over all *.xml files in a specific directory. I hav...
Use OPENXML to get dt element in MSSQL 2005. How can I get xmlns:dt element in xml? For example, get a result set of two rows that list product id and country code. 121403 GBR 121403 USA declare @xmldata xml set @xmldata = '<?xml version="1.0"?> <data xmlns="http://www.aaa.com/master_browse_response" xmlns:dt="http://w...
I kind of have a feel for why the view is slower: The where clause is probably not applied at the same time. The results do seem to be the same, though. I am not sure what I can do about this, short of not using a view...which is not ideal, as I added the view to avoid code repetition, and I don't want to remove it if it isn't necessar...
Say you have WIDGETS table: WidgetID int ColorID int (Lookup values: Red, Blue, Green, Yellow, Black, Brown) SizeID int (Lookup values: Small, Med, Big, Large) Weight int (Lookup values: UltraLight, Light, Normal, Heavy, UltraHeavy Ok that's the general idea of the table. I don't need the lookup names, what I do have is the lookupva...
