我在SQL Server上出現這個奇怪的錯誤。而且我在舊帖子中找不到解決方案。服務器服務器上的MSDTC不可用
我有這樣的過程:
create proc _upJM_SyncAll_test
as
begin
DECLARE @SQLString nvarchar(max)
set @SQLString = N'
DELETE FROM OPENQUERY([LOCAL_MYSQL],''SELECT acSubject FROM _utjm_setitemprices'') where acSubject not in (select acSubject from _uvJM_SetSubj)
DELETE FROM OPENQUERY([LOCAL_MYSQL],''SELECT acSubject FROM _utjm_setsubj'') where acSubject not in (select acSubject from _uvJM_SetSubj)
update a
set acName2 = b.acName2,
acName3 = b.acName3,
acAddress = b.acAddress,
acPost = b.acPost,
acPostName = b.acPostName,
acCountry = b.acCountry,
acVATCodePrefix = b.acVATCodePrefix,
acCode = b.acCode,
anDaysForPayment = b.anDaysForPayment
from OPENQUERY([LOCAL_MYSQL],''SELECT * FROM _utjm_setsubj'') a join _uvJM_SetSubj b on (a.acSubject = b.acSubject)
where 1=1
and ( isnull(a.acName2,'''') <> isnull(b.acName2,'''') OR
isnull(a.acName3,'''') <> isnull(b.acName3,'''') OR
isnull(a.acAddress,'''') <> isnull(b.acAddress,'''') OR
isnull(a.acPost,'''') <> isnull(b.acPost,'''') OR
isnull(a.acPostName,'''') <> isnull(b.acPostName,'''') OR
isnull(a.acCountry,'''') <> isnull(b.acCountry,'''') OR
isnull(a.acVATCodePrefix,'''') <> isnull(b.acVATCodePrefix,'''') OR
isnull(a.acCode,'''') <> isnull(b.acCode,'''') OR
isnull(a.anDaysForPayment,'''') <> isnull(b.anDaysForPayment,'''')
)
insert into OPENQUERY([LOCAL_MYSQL],''SELECT * FROM _utjm_setsubj'') (acSubject, acName2, acName3, acAddress, acPost, acPostName, acCountry, acVATCodePrefix, acCode, anDaysForPayment)
select b.acSubject, b.acName2, b.acName3, b.acAddress, b.acPost, b.acPostName, b.acCountry, b.acVATCodePrefix, b.acCode, b.anDaysForPayment
from OPENQUERY([LOCAL_MYSQL],''SELECT * FROM _utjm_setsubj'') a right join _uvJM_SetSubj b on (a.acSubject = b.acSubject)
where a.acSubject is null '
EXECUTE sp_executesql @SQLString;
end
當我像這樣運行管理工作室程序:
exec dbo._upJM_SyncAll_test
一切正常。我沒有錯誤,同步工作正常。
但是當我把執行中觸發這樣的:
create trigger _utrJM_SetSubj on tHE_SetSubj after insert, update, delete
as
begin
exec dbo._upJM_SyncAll_test
end
我得到這個錯誤:
Msg 8501, Level 16, State 3, Procedure _upJM_SyncAll_test, Line 54
MSDTC on server 'server' is unavailable.
程序_upJM_SyncAll_test只有39行...
爲什麼你首先使用動態SQL ?,看起來好像沒有必要 – Lamak 2015-04-02 13:32:55
好像這樣..鏈接服務器[LOCAL_MYSQL]啓動並運行,但它可能會發生,無法訪問。在這種情況下,如果sp_executesql返回錯誤我做了別的..請注意,_upJM_SyncAll_test只是測試過程中的這篇文章,_upJM_SyncAll更復雜。 – Kiki 2015-04-02 13:43:34
