使用php脚本运行时，带有where子句的oracle选择查询返回不完整的记录

Question

I have an sql query that runs just fine when directly run in Oracle SQL developer which shows 3k+ records. The problems comes when I run it through a php script it only shows about 20+ records please help! btw both queries are used the same values for WHERE clause i also tried using order by but same results appear.

here my query:

sql run in php:

function getAllCOBDataList() 
{
            $branchcode = $_SESSION['branchcode'];
            $officeId = $_SESSION['officeid'];
            //$expenseFilter = $_SESSION['earmark-expenseCode'];
            $cob_data_list = array();

            $conn = persistentDBConnect();

            $query = "WITH CTE_TotalBalance AS (Select BUDGETID ,sum(TOTALCOST)"
                   . " as CURRENT_BALANCE from (Select BUDGETID, TOTALCOST from"
                   . " FARU.BEMM_DATA_COB"
                   . " Union all"
                   . " Select BUDGETID, EARMARKAMOUNT "
                   . " from FARU.BEMM_TRANS_EARMARKINGLIST)"
                   . " GROUP BY BUDGETID)"
                   . "SELECT"
                   . " A.FYEAR, A.BUDGETID, A.PERSPECTIVEID as perspective, A.FUNDTYPE, A.PARTICULAR, A.TOTALCOST,"

                   . " WHERE G.BRANCHCODE = '$branchcode'";
                  // . " WHERE G.OFFICEID = '$officeId'"
                   //. " Order by A.BUDGETID Asc";
            //echo $query;
            $stmt = oci_parse($conn, $query);
            $result =oci_execute($stmt);

            while($result = oci_fetch_assoc($stmt)){
                $cob_data_list[] = $result;
            }
            return $cob_data_list;


}

TIA!

Check that you are actually connecting to the same user & DB in PHP and in SQL Developer (a common mistake).

Try adding some var_dump() calls and run the query in the command line PHP to check it works.

Add some error handling, see page 161 of Oracle's free book The Underground PHP and Oracle Manual .

You almost certainly should be using a bind variable instead of " WHERE G.BRANCHCODE = '$branchcode'"; because this is a potential, big security hole. And will impact application performance and scalability. Read up on oci_bind_by_name() .

When fetching lots of rows, you can tune performance with oci_set_prefetch() .
