mssql_result

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

mssql_result — Get result data

说明

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

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

参数

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.

Note:

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

返回值

Returns the contents of the specified cell.

范例

Example #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);
?>

Example #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);
?>

注释

Note:

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().

Recommended high-performance alternatives:

mssql_fetch_row() - Get row as enumerated array
mssql_fetch_array() - Fetch a result row as an associative array, a numeric array, or both
mssql_fetch_assoc() - Returns an associative array of the current row in the result
mssql_fetch_object() - Fetch row as object
