Upgrade (to IDS9.2) problem

Hi, all Your help will be greatly appreciated. I am doing the upgrading test from IDS7.31 to IDS9.2. Our applications are written in C++, RougeWave DBTools++ (ver 3.0) and ESQL/C (ver9.14) . In one of the application, we send a SQL statement to IDS via DBTools++ class. The SQL statement is exactly the following: "create index xostmp on ostate_tmptbl (os_netentityid); update statistics low for table ostate_tmptbl (os_netentityid); " This works well on IDS7.31. But on IDS9.2, I got -252 and -770 error. I have a work round for this problem. I can divide the above statement into 2 statement and send them to IDS by calling the same DBTools++ function twice. But this way, I must modify all of our application source, so I want to know why it does not work in IDS9.2 and if there are other solutions. Thanks for any idea. Harry
