Oracleのストアドプロシージャの書き方がわかりません。それは私にとっては新しいことです。

Table 1:  Bank:

Bank_Id    Description
001        FNB
002        ABSA

Table 2:  Config

Config    ConfigName
1         SUTS allocated
2         SUTS unallocated
3         GOV allocated
4         GOV unallocated

Table 3: Config_Value

Config_Value_Id      Bank_Id    Config_Item_Id  ConfigValue
1                    001         1              FNBSAD
2                    001         2              FNBSUAD
3                    001         3              FNBGAD
4                    001         4              FNBGUAD

Config_Value は、Config テーブルと Bank テーブルの間の関係です。

の 2 つの値を設定するコードを C# で記述すると、次のようになります。

  • 文字列銀行 = "FNB"
  • string paymentType = "SUTS"

次に、これらの値がストアド プロシージャに渡されます。次のようなストアド プロシージャに IF または SWITCH ステートメントを記述したいと考えています。

IF (@PaymentType == 'SUTS')
need to get two values:
  ConfigValue = @param1 where ConfigName = 'SUTS allocated' AND where bank = @bank
  ConfigValue = @param2 where ConfigName = 'SUTS unallocated' AND where bank = @bank

IF (@PaymentType == 'GOV')
need to get two values:
  ConfigValue = @param1 where ConfigName = 'GOVallocated' AND where bank = @bank
  ConfigValue = @param2 where ConfigName = 'GOV unallocated' AND where bank = @bank

値 (bank と paymentType) がストアド プロシージャに渡されると、bank と paymentType に基づいて ConfigValue の 2 つの値がフェッチされます。上記のようにストアドプロシージャに書き込む方法は？サンプルコードを教えてください。どうもありがとう！
