SQL ServerのCURSORは停止しません

Question

1つのテーブルから値を取得し、2番目のテーブルに挿入するためのカーソルを作成しています。挿入されるエントリはわずか35です。しかし、私のカーソルは止まらない。 1分経っても止まらない。私は実行を停止する必要があります。 エラーを教えてください。私は、カーソル処理が遅いとは思わないが、他の貢献者が示唆したように、古いスタイルがあなたのselect文に参加

は、2つのテーブルのサイズに応じて、長い時間がかかる場合があります。変更してみてください

Select a.O_B_ID as CF_B_ID, 
       a.O_B_LR_Datetime as CF_Date, 
       a.O_B_Bill_No as CF_Invoice_No, 
       a.Total_Quantity as CF_Quantity, 
       a.Total_Duty_Plus as CF_Amount, 
       a.Total_CST as CF_Tax, 
       a.Total_CST_Plus as CF_Total_Amount 
     From Orders a 
     join C_Form b on a.O_B_Bill_No = b.CF_Invoice_No 
     where a.CST_TF = 1 
     AND b.CF_Invoice_No is null
