in thread Can i execute two queries connecting to same DB at a time.

Below is the my code my ( $data_source, $user_id, $password ) = qw( PHOENIX DBADMIN DBADMIN ); my $conn_string = "driver={SQL Server};Server=$data_source;Database=$database;UID=$user_id;PWD=$password"; my $dbh = DBI->connect( "DBI:ODBC:$conn_string" ) or die $DBI::errstr; my $sql1 = "SELECT CONTENT_HASH FROM DS_STAGING_CONTENTHASH where STAGING_STATUS_GID!=210"; my $sth = $dbh->prepare( $sql1 ); $sth->execute; In this i executed only one query (above code works fine). But when i try to execute another query by my $sql2 = "SELECT CASESHARE_PATH FROM DS_CASESHARE"; my $sth2 = $dbh->prepare( $sql2 ); $sth2->execute; This gives error as i mentioned above

    Please use <code> tags, this is unreadable. And read what I wrote about the protocol issue just five minutes ago.

    What part of Connection is busy with result and my reply:

    you still have a statement handle open and did not ->finish() it before trying to issue another SQL statement
    is giving you problems?

    Your code is opening a second SQL statement before retrieving all results from the first SQL statement. This does not work for your combination of database, OS and DBD.
