Обсуждение: vacuum from ecpg

The following program produces the output below...
It is built with:

vrfy_prob: vrfy_prob.cpg
  /usr/local/pgsql/bin/ecpg -I/usr/local/pgsql/include -o vrfy_prob.c vrfy_prob.cpg
  gcc -g${DEBUG} -I/usr/include/pgsql -o vrfy_prob -lm -lc -lecpg -lpq vrfy_prob.c

I am not using a BEGIN/END block, though the error messages indicate
that I am.

How can I do a vacuum analyze from within embedded sql in a c program
that works?

Thanks for your help!

Hello,

I might be wrong on this but I think that ecpg using transactions by
default for each query.
Perhaps turning on autocommit?

Yep, use:

    EXEC SQL SET AUTOCOMMIT = ON;

Or use 'ecpg -t'.
