[freetds] DBlib dbsqlexec question (chaining sql statements)

Yes, a white space is enough to separate to commands... but a new line
will look nicer in the Profiler utility.

But remember, dbresults must be called for each statement in the
command batch. A loop would be practical for this.

Also consider your Isolation Level and the proper Commit to end your
transaction...

Asunto: [freetds] DBlib dbsqlexec question (chaining sql statements)


Hi,

Have two (maybe more) sql statements that I'd like to run. I am
wondering if I can execute them at the same time. Example:

Now:
int i = 1;
int j = 3;
dbfcmd(dbproc,"delete from sss where col1 = %d",i);
dbsqlexec(dbproc);
dbresults(dbproc);
dbfcmd(dbproc,"delete from zzz where col1 = %d",j);
dbsqlexec(dbproc);
dbresults(dbproc);

I'd like to do:

dbfcmd(dbproc,"delete from sss where col1 = %d\n",i);
dbfcmd(dbproc,"delete from zzz where col1 = %d",j);
dbsqlexec(dbproc);
dbresults(dbproc);

Is there a command seperator that I put after the newline and / or how
many times to I have to call dbsqlexec or dbresults? Would this save
roundtrips to the database or is the method the way to go?
Thanks
