# mssql_bind

(PHP 4 >= 4.0.7, PHP 5, PECL odbtp:1.1.1-1.1.4)

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` [, int `$is_output` [, int `$is_null` [, int `$maxlen` ]]] )

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. You can pass it by value, or 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

$cn = mssql_connect($DBSERVER, $DBUSER, $DBPASS);
mssql_select_db($DB, $cn);
$sp = mssql_init("WDumpAdd"); // stored proc name
mssql_bind($sp, "@productname", stripslashes($newproduct), SQLVARCHAR, false, false, 150);
mssql_bind($sp, "@quantity", stripslashes($newquantity), SQLVARCHAR, false, false, 50);
