oci_parse
OCI_PARSE(3) OCI_PARSE(3)
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) : " ") . "</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.
