Corona is correct - most command line utilities are tuned and designed for a particular purpose, and really are very close to as good as it gets. Unless you are doing this to learn coding, or have some fun messing around with C, I would second the idea: use command line utilities.
A very good reason for this is the 'next guy'. Somebody may need to use what you have. Or modify it because the manager is having a bad day. If it is C code and does not quite cut it, that person will have to find the source and change it. Simplicity and transparency (like a shell script) has a lot to recommend it.
Dedicated well-designed C code is often provably faster than a script. But how fast do you have to go? That file is less than 1MB. So, C may save you 1 or 2ms on modern systems.

maxdb_stmt_sqlstate
MAXDB_STMT_SQLSTATE(3) 1 MAXDB_STMT_SQLSTATE(3)
maxdb_stmt_sqlstate - Returns SQLSTATE error from previous statement operation
SYNOPSIS
string maxdb_stmt_sqlstate (resource $stmt)
DESCRIPTION
Returns a string containing the SQLSTATE error code for the most recently invoked prepared statement function that can succeed or fail.
The error code consists of five characters. '00000' means no error. The values are specified by ANSI SQL and ODBC.
Note
Note that not all MaxDB errors are yet mapped to SQLSTATE's. The value HY000 (general error) is used for unmapped errors.
RETURN VALUES
Returns a string containing the SQLSTATE error code for the last error. The error code consists of five characters. '00000' means no
error.
EXAMPLES
Example #1
Object oriented style
<?php
/* Open a connection */
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city");
$maxdb->query("INSERT INTO temp.mycity SELECT * FROM hotel.city");
$query = "SELECT name, zip FROM temp.mycity ORDER BY name";
if ($stmt = $maxdb->prepare($query)) {
/* drop table */
$maxdb->query("DROP TABLE temp.mycity");
/* execute query */
$stmt->execute();
printf("Error: %s.
", $stmt->sqlstate);
/* close statement */
$stmt->close();
}
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
/* Open a connection */
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city");
maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");
$query = "SELECT name, zip FROM temp.mycity ORDER BY name";
if ($stmt = maxdb_prepare($link, $query)) {
/* drop table */
maxdb_query($link, "DROP TABLE temp.mycity");
/* execute query */
maxdb_stmt_execute($stmt);
printf("Error: %s.
", maxdb_stmt_sqlstate($stmt));
/* close statement */
maxdb_stmt_close($stmt);
}
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Warning: maxdb_stmt_execute(): -4004 POS(23) Unknown table name:MYCITY [42000] <...>
Error: 42000.
