Answer 2

を更新し、QISbatchlog.nm そして は、gl.nm はあなたがで複数の問題を持って、colum名 を変更するとあなたが追加することができます col1の

Answer 3

としてgl.nmを同じ列名を持ちますあなたの質問。内側のクエリで、同じ列名を持つ次の列を設定しています。内部クエリでASエイリアスを使用して一意の名前を使用します。

QISP.id 
QISeventlog.id 
QISprocess.id 

gl.nm 
QISbatchlog.nm 

QISprocess.nml 
QISvariable.nml 

sqlのselectリストによって一意の列名を返すことが必須です。
