OCIDefineByName

OCIDefineByName -- Use a PHP variable for the define-step during a SELECT

Description

int OCIDefineByName(int stmt, string Column-Name, mixed &variable, int [type]);

OCIDefineByName() uses fetches SQL-Columns into user-defined PHP-Variables. Be careful that Oracle user ALL-UPPERCASE column-names, whereby in your select you can also write lower-case. OCIDefineByName() expects the Column-Name to be in uppercase. If you define a variable that doesn't exists in you select statement, no error will be given!

If you need to define an abstract Datatype (LOB/ROWID/BFILE) you need to allocate it first using OCINewDescriptor() function. See also the OCIBindByName() function.

/* the define MUST be done BEFORE ociexecute! */

OCIDefineByName($stmt,"EMPNO",&$empno);
OCIDefineByName($stmt,"ENAME",&$ename);

OCIExecute($stmt);

while (OCIFetch($stmt)) {
    echo "empno:".$empno."\n";
    echo "ename:".$ename."\n";
