Can SQL Server Data Tools work with SQL Server 2008 SSIS

SQL Server 2005 onwards:

IF EXISTS(SELECT 1 FROM sys.columns 
          WHERE Name = N'columnName'
          AND Object_ID = Object_ID(N'schemaName.tableName'))
BEGIN
    -- Column Exists
END

Martin Smith's version is shorter:

IF COL_LENGTH('schemaName.tableName', 'columnName') IS NOT NULL
BEGIN
    -- Column Exists
END

Please check the ServerName which you provided. It should match with the below shown Name in the UserName textbox, and that name should followed with \SQLEXPRESS:
