mssql_result

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

mssql_resultGet 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().

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