Posted 2021-02-26

Minimal syntax for cursor use. See URL for SQL 2005 options and improvements.

DECLARE @EntityName AS VARCHAR(100)
 
    DECLARE DepNameCursor Cursor FAST_FORWARD 
    FOR SELECT top 100 MailName FROM DepNameExt
 
    OPEN DepNameCursor
    FETCH NEXT FROM DepNameCursor
    INTO @EntityName
 
    WHILE @@Fetch_Status = 0 
    BEGIN 
 
        INSERT INTO [UDC].[dbo].[Entity]
           ([Name])
        VALUES
           (@EntityName)
 
        FETCH NEXT FROM DepNameCursor
        INTO @EntityName
    END
 
    CLOSE DepNameCursor
    DEALLOCATE DepNameCursor
