参数

sp_name: Stored procedure name, like ownew.sp_name or otherdb.owner.sp_name.

Example #1 mssql_init() example


<?php
// Connect to MSSQL and select the database
$link = mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
mssql_select_db('php', $link);

// Create a new statement
$stmt = mssql_init('StatementTest', $link);

// Bind values here

// Once values are binded we execute our statement 
// using mssql_execute:
mssql_execute($stmt);

// And we can free it like so:
mssql_free_statement($stmt);
?>

this function was created to support  

OUTPUT parameters and return values with 

MSSQL stored procedures. Before this, 

you could use T-SQL statement EXECUTE 

and mssql_query to execute a stored 

procedure, and it was fine as long as 

you don't need to retrieve OUTPUT or 

RETVAL values.





Now you can use this set of functions to execute and retrieve these values:

mssql_init

mssql_bind

mssql_execute



Parameters:

- sp_name : stored procedure name. It passes this string to a native DB-lib call, so I guess it supports all kinds of schemas (like "ownew.sp_name" or "otherdb.owner.sp_name")



- connection id: a connection resource 

obtained with mssql_connect or similar. 

If not provided, it will proceed just 

like other similar mssql_* functions: 

uses a default open connection or 

creates a new one.



Return value: a resource id, called 

"statement", used in subsequent calls to 

mssql_bind and mssql_execute.



Note that many of the native MSSQL data types are directly supported, but I 

think that some others must be converted 

by other means (from varchar values for 

example). These unsupported types are:



SQLMONEY4,SQLMONEY,SQLBIT,SQLDATETIM4,

SQLDATETIME, SQLDECIMAL, SQLNUMERIC, 

SQLVARBINARY, SQLBINARY,SQLIMAGE

If you are performing a stored procedure inside a loop, it is a good idea to unset the variable that mssql_init returns so that you do NOT bind multiple values to the same stored procedure:

foreach($input  as $sid=>$value) {
  $stmt = mssql_init("sp_doSomething");
  mssql_bind($stmt, "@sid", $sid, SQLINT4, false);
  mssql_bind($stmt, "@value", $value, SQLINT4, false);
  $result = mssql_execute($stmt);
  unset($stmt);  // <---VERY important
}

Even doing the mssql_init outside the loop does not help because of the multiple binds happening inside the loop.

Failing to do the above generates "Access Violations...memory cannot be 'written'" errors on the server.  My hypothesis is that the error is generated when you try to bind to a stored procedure after it has already been executed.  You have been warned.
