Re: [newbie] How to do "batch insert"?

Hi Ian,

It should be much easier to use pg_query function.

pg_query("START TRANSACTION");
  for (......)
   {
     $your_insert_query = "INSERT INTO acls(oid,uid,gid,mod)  
VALUES($1,$2,$3,$4)"
     $r = pg_query($your_insert_query);
        if (!$r) //Query failed
         {
            //issue error message
           // exit loop, all changes in the table will not be saved
         }
    }
pg_query("COMMIT"); //Commit all changes in the table

If you mark the transaction block ("start transaction" ... "commit")  
the changes will be commited only after the script reaches "commit"  
clause. If it is aborted before, no changes will be saved. This is the  
purpose of transaction (which is also the way to increase the speed of  
the program execution).
