mssql_result

(PHP 4, PHP 5, PECL odbtp >= 1.1.1)

mssql_resultGet result data

Опис

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

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

Параметри

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.

Зауваження:

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

Значення, що повертаються

Returns the contents of the specified cell.

if (!mssql_num_rows($query)) {
    echo 
'No records found';
} else {
    while (
$row mssql_fetch_array($query)) {

?>

Примітки

Зауваження:

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().

The "i" parameter appears to be the row number.  This was implied by checking mysql_result, which documents what the middle paramter specifies.
