Question

PASS ENVIRONMENT VARIABLE FROM OSQL COMMAND TO COMMAND PROMPT

Asked by: computerstreber

I have a SQL statement that I am running via OSQL. Here is that statement

OSQL -S -E -Q"SELECT [name] FROM sysusers WHERE [name] = 'public'"

I would like to pass the result set into an environment variable so that I can echo it or use it for some other purpose.

Here is an example of what I am trying to accomplish:

@echo off

OSQL -S -E -Q"SELECT [name] FROM sysusers WHERE [name] = 'public'"

echo %result%

pause

This may not put it into the right output, but you can try:

@echo off 
OSQL -S -E -Q"SELECT [name] FROM sysusers WHERE [name] = 'public'" -o"results.txt"
type results.txt 
pause

I want to pass the variable to an environment variable so I can use it again within the batch file.

Well I don't think you can do that.  Maybe someone else will have an idea.

If the command returns one line try either using a set/p or for command, you can combine these onto one line or use a temp file, e.g.

@echo off
set tempfile="%Temp%\tempfile.txt"
del %tempfile 2>NUL
OSQL -S -E -Q"SELECT [name] FROM sysusers WHERE [name] = 'public'">%tempfile%
set /p myvar1=<%tempfile%
echo Using set/p for one lines worth: %myvar1%
set lastline=
for /f "tokens=*" %%a in ('type %tempfile%') do set lastline=%%a & echo Line found: %%a
echo The last line in the file was %lastline%

You might be able to use -o"%tempfile%" on the end of the SQL instead of using redirection too by the looks of it.
The set/p takes input from a file or console and applies the first line to the variable (intended for console input).  The for command can read the file / command output line by line and return whatever it is you need.  Combined with a FIND command to find specific lines or a counter to find line "N" give us the expected output of the OSQL command and what you want to see if needed.

You won't be able to create the environment variable per se, but you can capture the output with the /o option. Just make your SQL select (or print) a very recognisable string...

What you can also do is then search for a string and set the variable or results accordingly... which is (just realised it sounded familiar) what dragon-it is suggesting...

Or if possible, from within your script, output a batch/command file from SQL server (if you are permitted to use xp_cmdshell) and then run that...
