語法在通過在休眠Sql中連接兩個表從數據庫檢索數據時出錯

Question

String query ="From transaction JOIN outlet transaction.outlet_ref_id = outlet.outletid WHERE(transaction.added_date_time between'"+sdate+"' and '"+edate+"') and (outlet.merchant ="+merchantId+")"; 

這是我用來從數據庫中檢索數據的查詢。當我在Navicat中使用這個查詢並提供數據時，這工作正常。但我使用它作爲一個hibernate查詢，它給出了以下錯誤。

Answer 1

你需要寫的查詢鏈接：from Company as comp inner join comp.employees as emp。 Company as comp表示entityName as referenceName。

From Transaction t JOIN Outlet o t.outlet_ref_id = o.outletid WHERE(t.added_date_time between'"+sdate+"' and '"+edate+"') and (o.merchant ="+merchantId+")

使用實體名稱上Transaction
