Get result data - Справочник: PHP5.4

Описание

string mssql_result ( resource $result , int $row , mixed $field )

mssql_result() returns the contents of one cell from a MS SQL result set.

Список параметров

result: The result resource that is being evaluated. This result comes from a call to mssql_query().
row: The row number.
field: Can be the field's offset, the field's name or the field's table dot field's name (tablename.fieldname). If the column name has been aliased ('select foo as bar from...'), it uses the alias instead of the column name.

Замечание:
Specifying a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.

Возвращаемые значения

    echo 'No records found';
} else {
    for ($i = 0; $i < mssql_num_rows($query); ++$i) {

Примечания

Замечание:
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these functions return the contents of multiple cells in one function call, they're MUCH quicker than mssql_result().
