large insert script (generated from tasks) - errors when running from sqlcmd I have a large generated .sql file for the data from our UAT database.  I'm trying to load that into my (localdb)\v11.0 using sqlcmd.

I was able to use the following:

sqlcmd -S (localdb)\v11.0 -d myDB -I c:\temp\mydatafile.sql


The .sql file is 5GB. Everything seemed to be doing well; however, at the end of the output in the command window I see an error:


  Msg 102, Level 15, State 1
  Incorrect syntax near...


Apparently the data that it is pulling from the DB doesn't work in the insert statements.  Since the file is 5GB it won't open in an editor, so I can't fix it.

I did a quick data compare and I see records not in my localdb that are in the UAT database.  So that leads me to believe that it did not finish inserting all the data.

Is there a way to skip over these types of errors using sqlcmd? 

It would appear that if I can't open the file, yet sqlcmd is running into errors when running that file that the next best thing is knowing what table has that error.

My next question is, is there a way to message out what table has that error so I can exclude it from the original script?
I don't have a 5gb file to test against, so I have no idea if this proposed solution will work for you.  Your data may not lend itself to this proposed solution, but I thought I'd offer it anyway.

I created a table called SqlCommands

USE [Test]
GO
CREATE TABLE [dbo].[SqlCommands](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [TextData] [varchar](max) NOT NULL,
 CONSTRAINT [PK_SqlCommands] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO


For testing purposes, I used the SSMS scripting wizard to script one of my small tables (data) as 'inserts' into a test file.

I then used a Powershell script to read that test file (which are basically SQL insert commands into the above SqlCommands table.  The table has an identity column and the Powershell script only references the 'TextData'  column.  The ID identity column will allow me to select from this table in the correct order.  Here is the Powershell script:

$database = "test"
$server = "."
$table = "dbo.SqlCommands"

$ff="C:\Test\TestData.txt"
write-host "Input file used is $ff"
$inrec=""
$counter=0

if ([System.IO.File]::Exists($ff))
{
  $obj=new-object System.IO.StreamReader($ff)

  $inrec=$obj.ReadLine()
  while ($inrec -ne $null)
  {

     #replace single quotes with double quotes so the insert will work for literals
     $inrec = $inrec -Replace("'","''")

     Invoke-SqlCmd -Database $database -ServerInstance $server -Query "insert into $table (TextData) values('$inrec')"
     $counter++

     $inrec=$obj.ReadLine()
  }
  $obj.close()

  write-host "$counter lines read"
}
else
{
   write-host "Source file ($ff) does not exist." 
}

write-host "All done now!"


Now, I have my SQL file in a table.  I wrote a cursor to select from the table ordering by ID to make sure I'm executing the commands in the correct order.  The cursor script reads each row from the SqlCommands table and checks to see if it is a 'GO' statement ('GO' statements were automatically added by the scripting wizard when I scripted the table data).  If the row is NOT a 'GO', the current row is concatenated to @cmd and the next row is read.  If the current row is a 'GO', I execute the accumulated @cmd and blank @cmd out for the next series of statements.  The EXEC is wrapped inside a TRY/CATCH.  In the event of an error, I'm able to display the row number (Identity ID column) so I can run selects against the SqlCommands table 'around' that row number to find any problems.

SET NOCOUNT ON

DECLARE @cmd VARCHAR(max) = ' '
DECLARE @Id INT
DECLARE @textdata VARCHAR(max)

DECLARE _CURSOR CURSOR LOCAL FORWARD_ONLY STATIC READ_ONLY
FOR
SELECT ID
    ,TextData
FROM [Test].[dbo].[SqlCommands]
ORDER BY ID

DECLARE @count INT

SET @count = 0

OPEN _CURSOR

FETCH NEXT
FROM _CURSOR
INTO @Id
    ,@textdata

WHILE @@FETCH_STATUS = 0
BEGIN
    IF @textdata = 'GO'
    BEGIN
        BEGIN TRY
            --print @cmd
            EXEC (@cmd)
        END TRY

        BEGIN CATCH
            PRINT 'Error occurred at line ' + convert(VARCHAR(100), @Id)
            PRINT error_message()
        END CATCH

        SET @cmd = ' '
    END
    ELSE
    BEGIN
        SET @cmd += @textdata
    END

    FETCH NEXT
    FROM _CURSOR
    INTO @Id
        ,@textdata
END --End While

CLOSE _CURSOR

DEALLOCATE _CURSOR

PRINT @count


If any errors exist, I can use the row number to try and find the error

select * from [Test].[dbo].[SqlCommands] where id between 25 and 30
