在sql

Question

我正在使用以下存储在sqlserver中，我无法弄清楚在这个存储过程中传递数组。数组正是这种格式的c＃代码ABC，DEF或者我可以写字符串abc =“ABC，DEF”;

ALTER PROCEDURE [dbo].[BookedChemicalsLists]
        @RigNameValue VARCHAR(50) = null
AS
BEGIN
      SET NOCOUNT ON;   

      SELECT *
      FROM [BookedChemicals]
      WHERE AND (RigName IN (@RigNameValue,',') OR @RigNameValue IS NULL )
END
