This should make my app much faster. 回答1: You're looking for ColumnAttribute.AutoSync. If you're using the designer, check each

问题 Anybody have a nice tight and efficient SQL Server function that will return the fist string (terminated by a whitespace) following the first match of a given string. I've got some code, but it's real ugly and probably slow. For example, in In test 12545 file:x12545.jpg appears to be good given file: would return x12345.jpg Thanks. 回答1: create function dbo.extractAfter(@full nvarchar(max), @part nvarchar(max)) returns nvarchar(max) with returns null on null input as begin return ltrim(stuff

问题 Is there a difference between default sort order for a select query in SQL Server 2005 and SQL Server 2012? I have a table variable without a primary key.
