oci_parse

(PHP 5, PECL OCI8 >= 1.1.0)

oci_parsePrepares an Oracle statement for execution

Description

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 (";").

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 (
$row oci_fetch_array($stidOCI_ASSOC+OCI_RETURN_NULLS)) {
    echo 
"<tr>\n";
    foreach (
$row as $item) {
        echo 
"    <td>" . ($item !== null htmlentities($itemENT_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($stid':p2'$p240);

oci_execute($stid);

print 
"$p2\n";   // prints 16

oci_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.
