oci_parse

(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)

oci_parsePrepares an Oracle statement for execution

Description

oci_parse(resource $connection, string $sql): resource|false

Prepares sql 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

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 16

oci_free_statement($stid);
oci_close($conn);

?>

Notes

Note:

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