我正在尝试构建一个rest api应用程序。我正在构建的其余应用程序提供了一个mysql数据库的特定查询。我在理解@NamedQueries
时遇到了问题我想从sql查询中创建一个命名查询
SELECT C.*
FROM MDM_MASTER.Customer as C
INNER JOIN MDM_MASTER.SystemAccount as S
ON C.x_customerid = S.x_fkcustomer_x_customerid
WHERE S.x_datasourcename = 'Uber Proper' AND S.x_systemaccountid = 118096
AND S.x_accountstatus ='Active'
AND C.x_customercode = 'C001826' AND C.x_customerstatus = 'Active';
我做了名字查询
@NamedQuery( name = "Customer.findCustomerBySystemAccountIdAndCustomerCode"
, query = "SELECT cu FROM Customer cu INNER JOIN cu.systemAccounts as s "+
"WHERE s.xSystemaccountid = ?1 AND s.xDatasourcename = ?2 "+
"AND s.xAccountstatus = ?3 AND cu.xCustomercode = ?4 AND "+
"cu.xCustomerstatus = ?5")
但是当我在Controller中使用查询时，我得到的是null结果。我认为NamedQuery有问题。我做错了什么？
我会把大部分课程放在下面，以防其他问题出现。
