これはSSRSレポート用ですので、私は一時表を使用しています。私は2つのテーブルを持っています.1つは取引のためのテーブルで、私はアカウントと金額を引き出すために使っています。 2番目はトランザクションに基づいて調整しようとしている償却された延滞情報ですが、構文上の問題が発生しています。 case文は、カーソルや更新で使用できないのですか?ネストされたカーソルベースの更新
--Example Transaction:Account 123456 Principal 500.00 Interest 250.00
delinquent 5 months of 200 principal each month, the transaction had principal amount of 500, the first two are left alone, the third is reduced to 100 to match the total to the transaction amount, leaving a remaining amount of 0
--Delinquent data
-- 11/2015 Prin 200 Int 80 -> Prin 0 Int 0 (running total Prin 500 Int 250)
-- 10/2015 Prin 200 Int 80 -> Prin 0 Int 10 (running total Prin 500 Int 250)
-- 9/2015 Prin 200 Int 80 -> Prin 100 Int 80 (running total Prin 500 Int 240)
-- 8/2015 Prin 200 Int 80 -> Prin 200 Int 80 (running total Prin 400 Int 160)
-- 7/2015 Prin 200 Int 80 -> Prin 200 Int 80 (running total Prin 200 Int 80) <- process starts from the oldest and goes up.
それは次の行の調整を続けていく次いで、最も古い行で始まる調整、残りの合計を見つけなければならないように、私はセットに処理できないので、これは、カーソルを使用する必要があります。トランザクション量に達すると、残りの行はゼロになります。残りの金額を取引表に戻します。

私は文は私にエラーを与えているとき、なぜ私の場合を把握するために取得することができます任意の洞察力をいただければと思います。私は、ケースロジックが動作しないようにするmsdn構文には何も見ません。
私はそれを選択するか、設定されていなかったという事実を逃したかわかりません。ありがとう。 – xenapan
