oci_parse - Prepares an Oracle statement for execution

SYNOPSIS
resource oci_parse (resource $connection, string $sql_text) DESCRIPTION
Prepares $sql_text using $connection and returns the statement identifier, which can be used with oci_bind_by_name(3), oci_execute(3) and other functions. Statement identifiers can be freed with oci_free_statement(3) or by setting the variable to NULL. PARAMETERS
o $connection - An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3). o $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(3) 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($stid); echo "<table border='1'> "; while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) { echo "<tr> "; foreach ($row as $item) { echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : "&nbsp;") . "</td> "; } echo "</tr> "; } echo "</table> "; ?> Example #2 oci_parse(3) 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 "$p2 "; // prints 16 oci_free_statement($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. SEE ALSO
