maxdb_stmt_result_metadata -- Returns result set metadata from a prepared statement

Description

Procedural style:

mixed maxdb_stmt_result_metadata ( resource stmt )

If a statement passed to maxdb_prepare() is one that produces a result set, maxdb_stmt_result_metadata() returns the result resource that can be used to process the meta information such as total number of fields and individual field information.

Nota: This result set pointer can be passed as an argument to any of the field-based functions that process result set metadata, such as:

The result set structure should be freed when you are done with it, which you can do by passing it to maxdb_free_result()

Nota: The result set returned by maxdb_stmt_result_metadata() contains only metadata. It does not contain any row results. The rows are obtained by using the statement handle with maxdb_fetch().

Valores Retornados

maxdb_stmt_result_metadata() returns a result resource or FALSE if an error occured.

Example

Exemplo 1. Procedural style

<?php
$link
= maxdb_connect("localhost", "MONA", "RED");

maxdb_query($link, "CREATE TABLE temp.friends (id int, name varchar(20))");

maxdb_query($link, "INSERT INTO temp.friends VALUES (1,'Hartmut')");
maxdb_query($link, "INSERT INTO temp.friends VALUES (2, 'Ulf')");

$stmt = maxdb_prepare($link, "SELECT id, name FROM temp.friends");
maxdb_stmt_execute($stmt);

/* get resultset for metadata */
$result = maxdb_stmt_result_metadata($stmt);

/* retrieve field information from metadata result set */
$field = maxdb_fetch_field($result);

printf("Fieldname: %s\n", $field->name);

/* close resultset */
maxdb_free_result($result);

/* close connection */
maxdb_close($link);
?>

The above examples would produce the following output:

Fieldname: ID
