oci_parse — Prepares an Oracle statement for execution

### Beschreibung

function 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`.

### Parameter-Liste

`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 (";").

### 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`. The only way to find out if `sql` is a valid SQL or PL/SQL statement is to execute it.
