在批处理脚本中使用Sql变量

Question

I have looked at a number of threads covering this but am unable to apply the advice to my stituation. I want to be able to run a block of code only if file1 exists and the row count from a sql command return a count greater than 0. Both must be true to run the code block (:RUNCODE). I have set up a number of IF's to handle this which jump to either :RUNCODE or :END.

    SET SqlServerName="SERVER1"
    SET SqlDatabaseName="DB1"
    SET SQL="SELECT COUNT(*) FROM TABLE1" 

    SQLCMD.exe -S%SqlServerName% -E -d%SqlDatabaseName%  -Q%SQL% -h -1 -o RowCount.txt

    SET /p RowCount= <RowCount.txt
    DEL RowCount.txt

    echo %RowCount%


    IF EXIST "File1" IF %RowCount% GTR 0 
    (
            ECHO Running the position Loader for EFA...
            GOTO RUNCODE
     )


    IF NOT EXIST "File1" IF %RowCount% EQU 0
    (              
            ECHO The Position File Does not Exist...
            GOTO END
    )

    IF EXIST "File1" IF %RowCount% EQU 0
    (
            ECHO The File Does not Exist...
            GOTO END
    )

    IF NOT EXIST "File1" IF %RowCount% GTR 0
    (
            ECHO The Position File Does not Exist...
            GOTO END 
    )

    :RUNCODE 
    echo Running code block now now...
    EXIT

    :END
    echo conditions not met...
    EXIT

The code above gives me RowCount=0 (with white space in the variable) and appears to completely skip the if conditions.

Any help would be greatly appreciated.

Example of the ouput script. Note that there is white space in front of the 0 and not in front of (1 row affected)

  0 

(1 row affected)

Your opening parenthesis for the IF's need to be on the same line.

IF EXIST "File1" IF %RowCount% GTR 0 (
        ECHO Running the position Loader for EFA...
        GOTO RUNCODE
)


IF NOT EXIST "File1" IF %RowCount% EQU 0 (              
        ECHO The Position File Does not Exist...
        GOTO END
)

IF EXIST "File1" IF %RowCount% EQU 0 (
        ECHO The File Does not Exist...
        GOTO END
)

IF NOT EXIST "File1" IF %RowCount% GTR 0 (
        ECHO The Position File Does not Exist...
        GOTO END 
)

Here is how you can get rowcount without the whitespace

SET SQL="SET NOCOUNT on SELECT COUNT(*) FROM dbo.ACCT" 

SQLCMD.exe -S%SqlServerName% -E -d%SqlDatabaseName%  -Q%SQL% -h -1 -o RowCount.txt
for /f "delims=" %%a in ('type Rowcount.txt') do Call :Trim rcount %%a
if /i exist RowCount.txt DEL /f /q RowCount.txt
echo %rcount%
exit /b

:Trim <return> <string>
for /f "tokens=1*" %%a in ("%*") do set "%%a=%%b"
exit /b
