maxdb_stmt_result_metadata
MAXDB_STMT_RESULT_METADATA(3) 1 MAXDB_STMT_RESULT_METADATA(3)maxdb_stmt_result_metadata - Returns result set metadata from a prepared statement
Procedural style
SYNOPSIS
resource maxdb_stmt_result_metadata (resource $stmt)
DESCRIPTION
Object oriented style
resource maxdb_stmt::result_metadata (void )
If a statement passed to maxdb_prepare(3) is one that produces a result set, maxdb_stmt_result_metadata(3) returns the result resource
that can be used to process the meta information such as total number of fields and individual field information.
Note
This result set pointer can be passed as an argument to any of the field-based functions that process result set metadata, such as:
omaxdb_num_fields(3)omaxdb_fetch_field(3)omaxdb_fetch_field_direct(3)omaxdb_fetch_fields(3)omaxdb_field_count(3)omaxdb_field_seek(3)omaxdb_field_tell(3)omaxdb_free_result(3)
The result set structure should be freed when you are done with it, which you can do by passing it to maxdb_free_result(3)
Note
The result set returned by maxdb_stmt_result_metadata(3) contains only metadata. It does not contain any row results. The rows are
obtained by using the statement handle with maxdb_fetch(3).
RETURN VALUES maxdb_stmt_result_metadata(3) returns a result resource or FALSE if an error occurred.
EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
$maxdb->query("CREATE TABLE temp.friends (id int, name varchar(20))");
$maxdb->query("INSERT INTO temp.friends VALUES (1,'Hartmut')");
$maxdb->query("INSERT INTO temp.friends VALUES (2, 'Ulf')");
$stmt = $maxdb->prepare("SELECT id, name FROM temp.friends");
$stmt->execute();
/* get resultset for metadata */
$result = $stmt->result_metadata();
/* retrieve field information from metadata result set */
$field = $result->fetch_field();
printf("Fieldname: %s
", $field->name);
/* close resultset */
$result->close();
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
maxdb_query($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
", $field->name);
/* close resultset */
maxdb_free_result($result);
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Fieldname: ID
