Question

I have a query like this:

use DataIncremental
go
DECLARE @row_terminator CHAR;
SET @row_terminator = CHAR(10); -- or char(10)

BEGIN TRAN tran2


DECLARE @stmt NVARCHAR(2000);
SET @stmt = '
  BULK INSERT accn_adjustments
   FROM ''C:\Users\agordon\Desktop\incrementaljan2012\accn_adjustments_201112302112.txt''
   WITH 
      (
        firstrow=2,
FIELDTERMINATOR = ''|''  ,
ROWS_PER_BATCH=10000
   ,ROWTERMINATOR='''+@row_terminator+'''
   )'
exec sp_executesql @stmt;
SET @stmt = '
  BULK INSERT accn_adjustments
   FROM ''C:\Users\agordon\Desktop\incrementaljan2012\accn_adjustments_201112312112.txt''
   WITH 
      (
        firstrow=2,
FIELDTERMINATOR = ''|''  ,
ROWS_PER_BATCH=10000
   ,ROWTERMINATOR='''+@row_terminator+'''
   )'
exec sp_executesql @stmt;
SET @stmt = '
  BULK INSERT accn_adjustments
   FROM ''C:\Users\agordon\Desktop\incrementaljan2012\accn_adjustments_201201022101.txt''
   WITH 
      (
        firstrow=2,
FIELDTERMINATOR = ''|''  ,
ROWS_PER_BATCH=10000
   ,ROWTERMINATOR='''+@row_terminator+'''
   )'
exec sp_executesql @stmt;
SET @stmt = '
  BULK INSERT accn_adjustments
   FROM ''C:\Users\agordon\Desktop\incrementaljan2012\accn_adjustments_201201032101.txt''
   WITH 
      (
        firstrow=2,
FIELDTERMINATOR = ''|''  ,
ROWS_PER_BATCH=10000
   ,ROWTERMINATOR='''+@row_terminator+'''
   )'
exec sp_executesql @stmt;

The reason I put begin tran tran2 is to ensure that if there are errors I can just do a rollback

I ran the code and the message I got was "query completed with errors"

SSMS did NOT state that some rows were inserted as it usually does.

When I tried to do a rollback tran tran2, it said that that transaction never began

So my question is, were rows committed to the database or not?

If not, then why did it state “query completed with errors” shouldnt it just have said query did not complete due to errors?

Description

Since SQL Server 2005 you can use error handling using TRY CATCH

TRY…CATCH (Transact-SQL) Implements error handling for Transact-SQL that is similar to the exception handling in the Microsoft Visual C# and Microsoft Visual C++ languages. A group of Transact-SQL statements can be enclosed in a TRY block. If an error occurs in the TRY block, control is passed to another group of statements that is enclosed in a CATCH block.

Sample

BEGIN TRY
    BEGIN TRANSACTION

     -- do something

    COMMIT TRAN -- Transaction successfull, commit!
END TRY
BEGIN CATCH
    IF @@TRANCOUNT > 0
        ROLLBACK TRAN --RollBack if error occured
END CATCH
