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 SEE ALSO

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.
