mssql_bind

(PHP 4 >= 4.0.7, PHP 5, PECL odbtp >= 1.1.1)

mssql_bind — Adds a parameter to a stored procedure or a remote stored procedure

Description

bool mssql_bind ( resource $stmt , string $param_name , mixed &$var , int $type [, bool $is_output = false [, bool $is_null = false [, int $maxlen = -1 ]]] )

Binds a parameter to a stored procedure or a remote stored procedure.

Parameters

stmt: Statement resource, obtained with mssql_init().
param_name: The parameter name, as a string.

Note: You have to include the @ character, like in the T-SQL syntax. See the explanation included in mssql_execute().
var: The PHP variable you'll bind the MSSQL parameter to. It is passed by reference, to retrieve OUTPUT and RETVAL values after the procedure execution.
type: One of: SQLTEXT, SQLVARCHAR, SQLCHAR, SQLINT1, SQLINT2, SQLINT4, SQLBIT, SQLFLT4, SQLFLT8, SQLFLTN.
is_output: Whether the value is an OUTPUT parameter or not. If it's an OUTPUT parameter and you don't mention it, it will be treated as a normal input parameter and no error will be thrown.
is_null: Whether the parameter is NULL or not. Passing the NULL value as var will not do the job.
maxlen: Used with char/varchar values. You have to indicate the length of the data so if the parameter is a varchar(50), the type must be SQLVARCHAR and this value 50.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 mssql_bind() example


<?php
// Connect to MSSQL
mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
mssql_select_db('php');

// Create a new stored prodecure
$stmt = mssql_init('NewUserRecord');

// Bind the field names
mssql_bind($stmt, '@username',  'Kalle',        SQLVARCHAR,     false,  false,  60);
mssql_bind($stmt, '@name',      'Kalle',        SQLVARCHAR,     false,  false,  60);
mssql_bind($stmt, '@age',       19,             SQLINT1,        false,  false,   3);

// Execute 
mssql_execute($stmt);

// Free statement
mssql_free_statement($stmt);
?>


Use:

SQLVARCHAR for binary

SQLINT4 for datetime

SQLFLT8 for decimal

SQLVARCHAR for image

SQLFLT8 for money

SQLCHAR for nchar

SQLTEXT for ntext

SQLFLT8 for numeric

SQLVARCHAR for nvarchar

SQLFLT8 for real

SQLINT4 for smalldatetime

SQLFLT8 for smallmoney

SQLVARCHAR for sql_variant

SQLINT4 for timestamp

SQLVARCHAR for varbinary

I had the same problem but the posted solution above just produced null results.  Here's a modification that ended up working:



#THIS SUCCEEDS, USES A REFERENCE

mssql_bind($proc, '@'.$key, $sp_parms[$key], SQLVARCHAR)

or die("Unable to bind $sp_name:$key<br>".mssql_get_last_message());

mssql_bind binds by reference, not by value, even on input parameters.  Improper binding can cause strange errors; in my case "Error converting data type varchar to int"



--SAMPLE STORED PROCEDURE

CREATE Procedure [dbo].[myproc]

(

    @one VARCHAR(10) = 'n1',

    @two VARCHAR(10) = 'n2',

    @three VARCHAR(10) = 'n3',

    @four VARCHAR(10) = 'n4',

    @five VARCHAR(10) = 'n5'

)

AS

BEGIN

SET NOCOUNT ON;



SELECT

    @one AS 'one',

    @two AS 'two',

    @three AS 'three',

    @four AS 'four',

    @five AS 'five'

END



//SAMPLE PHP CALL

$sp_name = 'mydb.dbo.myproc';

$proc = mssql_init($sp_name);

$sp_parms->one = 'one';

$sp_parms->two = 'two';

$sp_parms->three = 'three';



foreach ($sp_parms as $key=>$parm) {

    #THIS FAILS, because it's binding values!

    #mssql_bind($proc, '@'.$key, $parm, SQLVARCHAR)

    #    or die("Unable to bind $sp_name:$key<br>".mssql_get_last_message());

    #THIS SUCCEEDS, USES A REFERENCE

    mssql_bind($proc, '@'.$key, $sp_parms->$key, SQLVARCHAR)

        or die("Unable to bind $sp_name:$key<br>".mssql_get_last_message());

}

add a note
