请您尝试申请我的网站上正在处理的请求，并收到此错误：
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The 'CalCulateClaimForDeath' procedure attempted to return a status of NULL, which is not allowed. A status of 0 will be returned instead.
源错误向我指出了这段代码：
Line 239:
Line 240: //finally, execute the command.
Line 241: int retval = cmd.ExecuteNonQuery();
Line 242:
Line 243: // detach the SqlParameters from the command object, so they can be used again.
需要帮助。谢谢你
