Question

我从存储过程中得到一个错误，我仔细检查了一下，发现该查询中发生了错误。

INSERT INTO Custodian (ID, EditVersion, DisplayValue, LookupKey, ImportTrackingID) 
    SELECT 
        NEWID(), 1, ImportActivity.Custodian, ImportActivity.Custodian, 
        '2eca1eba-68e0-4490-9e93-aa8f00eff76e'
    FROM
        ImportActivity
    WHERE 
        ImportActivity.BatchKey = '00317eb6-96fc-48c9-b530-e9fed3aea2ce'
        AND dbo.IsValidLookup(NULL, ImportActivity.Custodian, ImportActivity.Custodian) = 1
        AND NOT EXISTS (SELECT ID FROM Custodian WHERE Custodian.LookupKey = ImportActivity.Custodian)
    GROUP BY 
        ImportActivity.Custodian, ImportActivity.Custodian

在某些情况下，此SELECT查询返回空结果，然后发生错误：

SELECT 
    NEWID(), 1, ImportActivity.Custodian, ImportActivity.Custodian, 
    '2eca1eba-68e0-4490-9e93-aa8f00eff76e'
FROM 
    ImportActivity
WHERE 
    ImportActivity.BatchKey = '00317eb6-96fc-48c9-b530-e9fed3aea2ce'
    AND dbo.IsValidLookup(NULL, ImportActivity.Custodian, ImportActivity.Custodian) = 1
    AND NOT EXISTS (SELECT ID FROM Custodian WHERE Custodian.LookupKey = ImportActivity.Custodian)
GROUP BY 
    ImportActivity.Custodian, ImportActivity.Custodian

我想仅在存在INSERT结果的情况下运行SELECT查询。

这可以解决问题。

我该如何解决？

这是错误：

tr_Custodian_Insert E 1
  tr_Custodian_Update E 2

Msg 3930，第16级，状态1，过程tr_Custodian_Insert，第36行[批处理开始第2行]
  当前事务无法提交，并且不能支持写入日志文件的操作。回滚交易。

它发生在下面的Custodian表INSERT触发器中。

USE [LMAdvImportsTesting]
GO
/****** Object:  Trigger [dbo].[tr_Custodian_Insert]    Script Date: 7/24/2019 8:52:32 AM ******/

ALTER TRIGGER [dbo].[tr_Custodian_Insert] ON [dbo].[Custodian]

FOR INSERT
AS 

BEGIN

    IF ( UPDATE(LookupKey) OR UPDATE(BalanceType) )
    BEGIN

        BEGIN TRY

            -- Trigger setup
            DECLARE @Start datetime
            SELECT @Start = GETDATE()
            DECLARE @RoundAmount decimal(8,4)
            SELECT @RoundAmount = .02
            PRINT SPACE(5*@@NestLevel) + 'tr_Custodian_Insert E ' + RTRIM(CAST(@@NestLevel AS varchar(50)))
            SET NOCOUNT ON 

            -- Combined balances
            UPDATE Custodian
            SET Custodian.BalanceType = 1
            FROM Custodian 
                JOIN inserted ON Custodian.ID = inserted.ID
            WHERE Custodian.LookupKey IN ('TDAMERITRADE','THINKORSWIM','WELLSFARGO')
                AND Custodian.BalanceType <> 1

            -- Trigger cleanup
            PRINT SPACE(5*@@NestLevel) + 'tr_Custodian_Insert X ' + RTRIM(CAST(@@NestLevel AS varchar(50))) + ' ' + CAST(DATEDIFF(ms, @Start, GETDATE()) as varchar(200)) + 'ms'
        END TRY

        BEGIN CATCH
            DECLARE @error int, @line int, @message varchar(4000), @xstate int, @procedure varchar(128), @severity int, @state int;
            SELECT @error = ERROR_NUMBER(), @line=ERROR_LINE(), @message = ERROR_MESSAGE(), @procedure = ERROR_PROCEDURE(), @severity = ERROR_SEVERITY(), @state = ERROR_STATE()
            INSERT DBError (Error_Line, Source, Error_Number, Error_Message, Error_Procedure, Error_Severity, Error_State) VALUES (@line, 'tr_Custodian_Insert', @error, @message, @procedure, @severity, @state)
            RAISERROR ('tr_Custodian_Insert: %d: %s', 16, 1, @error, @message);
        END CATCH

    END

END
;

如何检查SELECT结果是否存在？
