このクエリ
SELECT *
FROM tblContracts
LEFT JOIN tblPartys ON tblContracts.id = tblPartys.Contract_id
INNER JOIN tblAdministrators
ON tblContracts.AdministratorID = tblAdministrators.ID
mysqlデータベースでは機能しますが、AccessDBでは機能しません!!!
私はこのエラーの打撃を受けています:
System.Data.OleDb.OleDbException:クエリ式の構文エラー(演算子がありません)'tblContracts.id = tblPartys.Contract_id INNER JOIN tblAdministrators ON tblContracts.AdministratorID=tblAdministrators.I'。System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr)at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS dbParams、Object&executeResult)at System.Data.OleDb.OleDbCommand.ExecuteCommandText(Object&executeResult)at System.Data OleDb.OleDbCommand.ExecuteCommand(CommandBehavior Behavior、Object&executeResult)at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior Behavior、String method)at System.Data.OleDb.OleDbCommand.ExecuteReader(CommandBehavior Behavior)
