解析:php调用MsSQL存储过程使用内置RETVAL获取过程中的return值

 $stmt = mssql_init('P__Global_Test', $conn) or die("initialize stored procedure failure");
 mssql_bind($stmt, "RETVAL", $returnValue, SQLINT4, true);
 mssql_execute($stmt, false);
        if( $returnValue == 0 ){
           echo 'ABCD';
        }
        else{ <PRE class=php name="code">           echo 'EFGH';</PRE> }&nbsp;

CREATE PROCEDURE dbo.P__User_JudgeResume(
)
set nocount on
 set @Message = ''

 if not exists( select * from _Test )
 begin
  return 0
 end
 else
 begin
  return 1
 end
set nocount off
