mssql_result — Get result data
mssql_result() returns the contents of one cell from a MS SQL result set.
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.
Informacja:
Specifying a numeric offset for the
fieldargument is much quicker than specifying a fieldname or tablename.fieldname argument.
Returns the contents of the specified cell.
Przykład #1 mssql_result() example
<?php
// Send a select query to MSSQL
$query = mssql_query('SELECT [username] FROM [php].[dbo].[userlist]');
// Check if there were any records
if (!mssql_num_rows($query)) {
echo 'No records found';
} else {
for ($i = 0; $i < mssql_num_rows($query); ++$i) {
echo mssql_result($query, $i, 'username'), PHP_EOL;
}
}
// Free the query result
mssql_free_result($query);
?>

Przykład #2 Faster alternative to above example
<?php
// Send a select query to MSSQL
$query = mssql_query('SELECT [username] FROM [php].[dbo].[userlist]');
// Check if there were any records
if (!mssql_num_rows($query)) {
echo 'No records found';
} else {
while ($row = mssql_fetch_array($query)) {
echo $row['username'], PHP_EOL;
}
}
// Free the query result
mssql_free_result($query);
?>
Informacja:
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().
