(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)

oci_parse — Prepares an Oracle statement for execution

Description

oci_parse ( resource $connection , string $sql_text ) : resource

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 (";").

Return Values

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

Examples

Example #1 oci_parse() example for SQL statements

<?php$conn = oci_connect('hr', 'welcome', 'localhost/XE');// Parse the statement. Note there is no final semi-colon in the SQL statement$stid = oci_parse($conn, 'SELECT * FROM employees');oci_execute($stid);echo "<table border='1'>\n";while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {    echo "<tr>\n";    foreach ($row as $item) {        echo "    <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : "&nbsp;") . "</td>\n";    }    echo "</tr>\n";}echo "</table>\n";?>

Example #2 oci_parse() example for PL/SQL statements

<?php/*  Before running the PHP program, create a stored procedure in  SQL*Plus or SQL Developer:  CREATE OR REPLACE PROCEDURE myproc(p1 IN NUMBER, p2 OUT NUMBER) AS  BEGIN      p2 := p1 * 2;  END;*/$conn = oci_connect('hr', 'welcome', 'localhost/XE');if (!$conn) {    $e = oci_error();    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);}$p1 = 8;// When parsing PL/SQL programs, there should be a final semi-colon in the string$stid = oci_parse($conn, 'begin myproc(:p1, :p2); end;');oci_bind_by_name($stid, ':p1', $p1);oci_bind_by_name($stid, ':p2', $p2, 40);oci_execute($stid);print "$p2\n";   // prints 16oci_free_statement($stid);oci_close($conn);?>

Notes

Note:

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.
