sqlsrv_next_result

Download PHP driver

Makes the next result (result set, row count, or output parameter) of the specified statement active.

Note

The first (or only) result returned by a batch query or stored procedure is active without a call to sqlsrv_next_result.

Syntax

  
sqlsrv_next_result( resource $stmt )  

Parameters

$stmt: The executed statement on which the next result is made active.

Return Value

If the next result was successfully made active, the Boolean value true is returned. If an error occurred in making the next result active, false is returned. If no more results are available, null is returned.

Example 1

The following example creates and executes a stored procedure that inserts a product review into the Production.ProductReview table, and then selects all reviews for the specified product. After execution of the stored procedure, the first result (the number of rows affected by the INSERT query in the stored procedure) is consumed without calling sqlsrv_next_result. The next result (the rows returned by the SELECT query in the stored procedure) is made available by calling sqlsrv_next_result and consumed using sqlsrv_fetch_array.

Note

Calling stored procedures using canonical syntax is the recommended practice. For more information about canonical syntax, see Calling a Stored Procedure.

The example assumes that SQL Server and the AdventureWorks database are installed on the local computer. All output is written to the console when the example is run from the command line.

When executing a stored procedure that has output parameters, it is recommended that all other results are consumed before accessing the values of output parameters. For more information see How to: Specify Parameter Direction Using the SQLSRV Driver.

Example 2

The following example executes a batch query that retrieves product review information for a specified product ID, inserts a review for the product, then again retrieves the product review information for the specified product ID. The newly inserted product review will be included in the final result set of the batch query. The example uses sqlsrv_next_result to move from one result of the batch query to the next.

Note

The first (or only) result returned by a batch query or stored procedure is active without a call to sqlsrv_next_result.

The example uses the Purchasing.ProductReview table of the AdventureWorks database, and assumes that this database is installed on the server. All output is written to the console when the example is run from the command line.

<?php  
/* Connect to the local server using Windows Authentication and  
specify the AdventureWorks database as the database in use. */  
$serverName = "(local)";

     echo "Could not connect.\n";
