PHP MSSQL - What Is a Result Set Object Returned by mssql_query()?

A result set object is a logical representation of data rows returned by mssql_query() function on SELECT statements. Every result set object has an internal pointer used to identify the current row in the result set. Once you get a result set object, you can use the following functions to retrieve detail information:

• mssql_free_result($res) - Closes this result set object.
• mssql_num_rows($res) - Returns the number rows in the result set.
• mssql_num_fields($res) - Returns the number fields in the result set.
• mssql_fetch_row($res) - Returns an array contains the next row indexed by field positions. The internal pointer is moved to the next row too.
• mssql_fetch_array($res) - Returns an array contains the next row indexed by field positions and field names. The internal pointer is moved to the next row too.
• mssql_fetch_assoc($res) - Returns an array contains the next row indexed by field names. The internal pointer is moved to the next row too.
• mssql_fetch_object($res) - Returns an object representing the next row. The internal pointer is moved to the next row too.
• mssql_field_name($res, $i) - Returns the name of the field with the specified index.
• mssql_field_type($res, $i) - Returns the data type of the field with the specified index.
• mssql_field_len($res, $i) - Returns the data type size of the field with the specified index.
