SQLAdapter像查询不工作

Question

我正在尝试使用LIKE Query，但这并没有给我任何结果集，也没有给我一个错误。它确实为我提供了完整搜索的结果集，例如，example @ test.com，但为例子为空

var FIND_CUSTOMER_PREPARED_STATEMENT = WL.Server.createSQLStatement(
        "SELECT CUST_ID, " +
        "EMAIL_ADDR, PHONE_NUM, FIRST_NAME, LAST_NAME, ADDR1, ADDR2, CITY_NAME, PROV_ST_CDE, " +
        "POST_ZIP_CDE, NOTES_TXT, DLR_CDE, ANALYS_TXT FROM " +
        "GS_DBA.CUI_CUST_INFO WHERE " +
        "(lower(EMAIL_ADDR) LIKE  lower(?) or ? is null) and " +
        "(PHONE_NUM = ? or ? is null) and " +
        "(lower(FIRST_NAME) = lower(?) or ? is null) and " +
        "(lower(LAST_NAME) = lower(?) or ? is null) and" +
        " Order By LAST_NAME, FIRST_NAME"
    );



function findCustomer(emailAddress, phoneNumber, firstName, lastName)
{


    return WL.Server.invokeSQLStatement({
        preparedStatement : FIND_CUSTOMER_PREPARED_STATEMENT,
        parameters : ["%"+emailAddress+"%", emailAddress, 
                      phoneNumber, phoneNumber,
                      firstName, firstName, 
                      lastName, lastName]
    });

}
