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. 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
NULLor not. Passing theNULLvalue asvarwill 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
SQLVARCHARand this value 50.
返回值
成功时返回 TRUE， 或者在失败时返回 FALSE。
