如何处理 sql server 2008 查询中的动态输入值。

我的情况是在下面的查询中，我有两个输入参数从 java 通过 i-batis 传递

 1) if i enter stlmtTransId field alone query should execute (paymentTransId  is empty now).
 2) if i enter paymentTransId field alone query should execute(stlmtTransId  is empty now).
 3) if i enter both input values query should execute for matching the two inputs.

在任何上述情况下，我都需要输出。如何处理它。

  SELECT
    STLMT_TRANS.SETTLEMENT_TRANSACTION_ID
    ,STLMT_TRANS.PC_TRANSACTION_ID
    ,STLMT_TRANS.TRANSACTION_AMOUNT
    ,STLMT_TRANS.PAYMENT_AGENT_ID
    ,STLMT_TRANS.PAYMENT_AGENCY_ID
    ,STLMT_TRANS.PAYMENT_TRANS_DATE
    FROM
    T_SETTLEMENT_TRANSACTION STLMT_TRANS WITH (NOLOCK)
    WHERE
    STLMT_TRANS.SETTLEMENT_TRANSACTION_ID=#stlmtTransId#
    AND
    STLMT_TRANS.PC_TRANSACTION_ID=#paymentTransId#

注意：我使用 java + I-Batis
