T SQL simple function

in 句に複数条件を渡す

配列形式のパラメータは無いらしい。

DECLARE @params TABLE(
      ID INT
);

INSERT INTO @params VALUES
   (1),(2),(3),(4),(5);


SELECT
 *
FROM
 my_table_01
WHERE  1=1
  AND  id in (select * from @params)

UPDATE文的なもの

declare @contract_id_before int = 67470;  -- 契約番号（変更前）
declare @contract_id_after  int = 67930;  -- 契約番号（変更後）


begin try
    begin tran;
        select * from prices where contract_id in (@contract_id_before, @contract_id_after);
        update prices set contract_id = @contract_id_after where contract_id = @contract_id_before;
        select * from prices where contract_id in (@contract_id_before, @contract_id_after);
    --commit tran;
    rollback tran;
end try
begin catch
    rollback tran;
    select
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;
end catch;
