问题 I have a complex query that I need to use in a subsequent query (actually update statement). I have tried both using a CTE and a temp table. The performance using the CTE is horrible vs the temp table approach. Its something like 15 seconds vs milliseconds. To simplify the test instead of joining the CTE/Temp table in the subsequent query I simply selected * from it. In that case they perform the same. I Have Looked at The Execution Plan for both approaches both with the joins in the

问题 I have a table with an autoincrement id that I am doing a INSERT INTO ( ... ) SELECT ... FROM ... Is there a way for me to get the list of id's that have been inserted? I was thinking I could get the max id before the insert then after and assuming everything in between is new, but then if a row gets inserted from somewhere else I could run into problems. Is there a proper way to do this? I am using SQL Server 2005 回答1: Use the output clause. DECLARE @InsertedIDs table(ID int); INSERT INTO

问题 I'm using SQL Server 2005, with a case sensitive database.. In a search function, I need to create a Linq To Entities (L2E) query with a "where" clause that compare several strings with the data in the database with these rules : The comparison is a "Contains" mode, not strict compare : easy as the string's Contains() method is allowed in L2E The comparison must be case insensitive : I use ToLower() on both elements to perform an insensitive comparison. All of this performs really well but I

问题 How do you specify field lengths with the Bulk Insert command? Example: If I had a table named c:\Temp\TableA.txt and it had: 123ABC 456DEF And I had a table such as: use tempdb CREATE TABLE TABLEA( Field1 char(3), Field2 char(3) ) BULK INSERT TableA FROM 'C:\Temp\TableA.txt' SELECT * FROM TableA Then how would I specify the lengths for Field1 and Field2? 回答1: I think you need to define a format file e.g. BULK INSERT TableA FROM 'C:\Temp\TableA.txt' WITH FORMATFILE = 'C:\Temp\Format.xml'

问题 How can I query Active Directory from SQL Server 2005? 回答1: Pretty general question but here are some pointers. You need a linked server creating on the SQL Server that points to ADSI (Active Directory Service Interface) something like this will do it. EXEC sp_addlinkedserver 'ADSI', 'Active Directory Services 2.5', 'ADSDSOObject', 'adsdatasource' Then you can use the following sort of query. SELECT * FROM OPENQUERY(ADSI, 'SELECT sAMAccountName FROM ''LDAP://DC=MyDC,DC=com,DC=uk'' WHERE
