sybase_result()

(PHP 4, PHP 5)

Get result data

Warning

This function wasREMOVEDin PHP 7.0.0.

说明

sybase_result(resource $result,int $row, mixed $field): string

Returns the contents of the cell at the row and offset in the specified Sybase result set.

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 sybase_result(). Also, note that specifying a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.

Recommended high-performance alternatives:sybase_fetch_row(),sybase_fetch_array() and sybase_fetch_object().

参数

$result

$row

$field

The field argument can be the field's offset, or 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...'), use the alias instead of the column name.

返回值

sybase_result() returns the contents of one cell from a Sybase result set.

If a stored procedure is doing all the work for you and you just need to retrieve a single cell...
<?php
$db = sybase_connect("sybtest", "sa", "users"); 
$query = sybase_query("EXEC usp_get_id @username='$username'", $db); 
$id = sybase_result($query,0,0);
echo $id;
?>
Simple.
