Hello,

Instead of the system function, you should probably look into popen, and read the stdout of the query. The result from system is the exit value of the p4sql program, not the result of the query. If you search, I'm sure that their are C++ classes that abstract all this for you, I just don't do enough in C++ to know of the top of my head.

You don't say what system this is on.... From a purely Unix perspective...

sh$ p4sql -i queries.sql < output here > sh$ echo $? < exit value of p4sql >

Hello,

Does anyone know how to get a p4sql result into a c++ variable? For example:

my queries.sql file:

------------------------------------- SELECT count(*) FROM changes changes, files files WHERE changes.change = files.change AND ((changes.description Like'xxx%') AND (filespec = '//depot/ProductLine/....java') );

my genPackage.c file

-------------------------------- .... int rows = system("p4sql -i queries.sql");

That doesn't seems to work. Is there a way where I can store the result into a c++ ariable?

Thanks,

Stacy
