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

说明

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.

参数

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.

返回值

如果成功则返回 TRUE，失败则返回 FALSE。

范例
