oci_parse

Prepares an Oracle statement for execution

Beschreibung

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.

Parameter-Liste

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 (";").

Rückgabewerte

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

Beispiele

Beispiel #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";

?>

Beispiel #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);

?>

Anmerkungen

Hinweis:
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.
