Я получаю эту странную ошибку на SQL Server. И я не могу найти решение в более старых сообщениях.
У меня есть эта процедура:
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
Когда я запускаю процедуру в студии управления следующим образом:
exec dbo._upJM_SyncAll_test
все в порядке. Я не получаю ошибки, синхронизация работает нормально.
Но когда я ставлю execute в триггере следующим образом:
create trigger _utrJM_SetSubj on tHE_SetSubj after insert, update, delete
as
begin
exec dbo._upJM_SyncAll_test
end
Я получаю эту ошибку:
Msg 8501, уровень 16, состояние 3, процедура _upJM_SyncAll_test, строка 54
MSDTC на сервере "сервер" недоступен.
Процедура _upJM_SyncAll_test имеет только 39 строк...
