Executing Data Definition Language (DDL) and Data Manipulation Language (DML)
statements, like CREATE and INSERT, simply requires a parse and execute:
$s = oci_parse($c1, "create table i1test (col1 number)");
oci_execute($s);
The only-run-once installation sections of applications should contain almost all the CREATE
TABLE statements used. Applications in Oracle do not commonly need to create temporary
tables at run time. Use inline views, or join tables when required. Temporary tables are
expensive to create and have no statistics for the Oracle optimizer to evaluate.
