“当你传递null return all”=＆gt; WHERE col = ISNULL(@argument, col)
其他条件应该有效，但初始查询的性能不是最好的（多个连接和where子句中的多个OR）可能会导致全表扫描。
您还可以为[dbo].Customer AS c等完全限定名称设置别名，然后将dbo.Customer.Surname简称为c.Surname
您可能在JOIN ON（同一表格和列）中遇到错误[dbo].Customer ON dbo.Cases.CustomerId = dbo.Cases.CustomerId

ALTER PROCEDURE [dbo].[Search_case]
(
     @AccountNo varchar(30) = null,
     @DateLogged datetime = null,
     @ReferenceNo varchar (50) = null,
     @ErfNo varchar (45) = null,
     @Surname varchar (255) = null,
     @Name varchar (255) = null,
     @ProcessInstanceId varchar (50) = null,
     @IdentityNo varchar (13) = null,
     @Summary varchar (max) = null,
     @Suspend varchar (10) = null,
     @Notes varchar (max) = null,
     @RatesNo varchar (30) = null,
     @Status varchar (50) = null
)
WITH EXECUTE AS OWNER, RECOMPILE
AS
    SET NOCOUNT ON;

    SELECT
        dbo.Cases.DateLogged,
        dbo.Cases.ReferenceNo,
        dbo.Account.AccountNo,
        dbo.Customer.RatesNo,
        dbo.Customer.IdentityNo,
        dbo.Account.ErfNo,
        dbo.Customer.Surname,
        dbo.Customer.Name,
        dbo.Cases.ProcessInstanceId,
        dbo.Cases.Status,
        dbo.Cases.Summary,
        dbo.Cases.Suspend,
        dbo.Cases.Notes
    FROM
        [ICSM_CORRES].[dbo].[Cases]
    INNER JOIN 
        [dbo].Customer ON dbo.Cases.CustomerId = dbo.Cases.CustomerId
    INNER JOIN
        dbo.Account ON dbo.Customer.AccountNoId = dbo.Account.AccountNoId
    WHERE
        dbo.Account.AccountNo = ISNULL(@AccountNo, dbo.Account.AccountNo)
        OR dbo.Customer.RatesNo = ISNULL(@RatesNo, dbo.Customer.RatesNo)
        OR dbo.Cases.DateLogged = ISNULL(@DateLogged, dbo.Cases.DateLogged)
        OR dbo.Cases.ReferenceNo = ISNULL(@ReferenceNo, dbo.Cases.ReferenceNo)
        OR dbo.Customer.IdentityNo = ISNULL(@IdentityNo, dbo.Customer.IdentityNo)
        /* ... and so on */
