How to set a sqlcmd output to a batch variable?

问题:

I'm trying to set the output of a sqlcmd query to a variable in a batch file.

Here's my query:

sqlcmd -S <SERVER> -d <DATABASE> -Q "select max(Column1)+1 from Table1"

This gives me exactly what I would expect and what I want:

-----------
         10
<1 rows affected>

However, when I try to set it to a variable, I used this script:

for /f %%a in ('sqlcmd -S <SERVER> -d <DATABASE> -Q "select max(Column1)+1 from Table1"') 
    do set ColumnVar=%%a
echo %ColumnVar%
pause

This gives me this result instead: <1 rows affected> I'm guessing this is because the loop is setting the variable to the last line. So is there a way I could use tokens and delims to parse out the 10 instead?

回答1:

Try turning on NOCOUNT:

for /f %%a in ('sqlcmd -S <SERVER> -d <DATABASE> -Q "SET NOCOUNT ON; select max(Column1)+1 from Table1"') 
    do set ColumnVar=%%a
echo %ColumnVar%
pause
