oci_parse

(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)
Prepares an Oracle statement for execution
resource oci_parse ( resource $connection, string $sql_text )

Prepares sql_text using connection and returns the statement identifier, which can be used with oci_bind_by_name(), oci_execute() and other functions.

Statement identifiers can be freed with oci_free_statement() or by setting the variable to NULL.

Parameters:
connection

An Oracle connection identifier, returned by oci_connect(), oci_pconnect(), or oci_new_connect().

sql_text

The SQL or PL/SQL statement.

SQL statements should not end with a semi-colon (";"). PL/SQL statements should end with a semi-colon (";").

Returns:

Returns a statement handle on success, or FALSE on error.

Notes:

This function does not validate sql_text. The only way to find out if sql_text is a valid SQL or PL/SQL statement is to execute it.
