There are 3 syntaxes for the UPDATE statement depending on whether you are performing a traditional update or updating one table with data from another table.

The_Table -- insert 20,000,000 records into the second table insert into AAA_DAVE_TEST_Target select top 20000000 * from dbo.

The_Table -- ensure there are differences so an update has to be performed Update AAA_DAVE_TEST_Target Set Fund_Code = 0 DECLARE @START_TIME datetime DECLARE @END_TIME datetime SELECT 'Starting Test' SET @START_TIME = GETDATE() UPDATE a SET [Account_Type] = b.[Account_Type] ,[Transaction_Type] = b.[Transaction_Type] ,[Branch_Code] = b.[Branch_Code] ,[Pay_Method_Cd] = b.[Pay_Method_Cd] ,[Trans_Date] = b.[Trans_Date] ,[Effective_Date] = b.[Effective_Date] ,[Amount] = b.[Amount] ,[Fund_Code] = b.[Fund_Code] ,[Batch_No] = b.[Batch_No] ,[Updated_Date] = b.[Updated_Date] ,[Updated_Time] = b.[Updated_Time] ,[Updated_Userid] = b.[Updated_Userid] ,[Archive_Ind] = b.[Archive_Ind] ,[Posted_Tran] = b.[Posted_Tran] ,[Updated_Session] = b.[Updated_Session] FROM AAA_DAVE_TEST_Target a inner join [AAA_DAVE_TEST_Source] b ON b.[Account_No] = a.[Account_No] AND b.[Transaction_Id] = a.[Transaction_Id] WHERE ( -- [ PLACEHOLDER ] -- This is the code that varies between techniques. -- ) SET @END_TIME = GETDATE() SELECT 'Finished', @END_TIME, 'Time To Run: ' CAST(DATEDIFF(SECOND, @START_TIME,@END_TIME) as varchar) ' seconds' -- drop the tables to also ensure nothing's cached and -- no statistics are kept which might affect results DROP TABLE AAA_DAVE_TEST_Source DROP TABLE AAA_DAVE_TEST_Target--ADD Checksum Col as BINARY_CHECKSUM([account_no],[transaction_id],[account_type],[transaction_type],[branch_code],[pay_method_cd],[trans_date],[effective_date],[amount],[fund_code],[batch_no],[Updated_date],[updated_time],[updated_userid],[archive_ind],[posted_tran],[updated_session])--ADD Checksum Col as BINARY_CHECKSUM([account_no],[transaction_id],[account_type],[transaction_type],[branch_code],[pay_method_cd],[trans_date],[effective_date],[amount],[fund_code],[batch_no],[Updated_date],[updated_time],[updated_userid],[archive_ind],[posted_tran],[updated_session])COALESCE(b.[Account_Type],'') !

The problem is that I have more than 10 conditions and it seems that SQL Server allows for only 10 levels of condition at most.

Experts, in SQL Server 2012, based on a conditional statement, if the condition is true, then I need to update more than one column.
