Question

对于Winform中的MSSQL更新，我想多次更新这些表。

您能给我评论吗？这将是一个简单的问题。

 UPDATE PC SET PC.statusId = '3', Rental.RealReturnDate = '2018-11-12', Rental.Reason = ''
 FROM PC, Rental WHERE PC.rentalId = Rental.rentalId AND tagNo = 'EK18LT00002'

Answer 1

您可以在下面尝试

BEGIN TRANSACTION;

UPDATE PC
SET PC.statusId = '3' 
FROM PC inner join Rental
on  PC.rentalId = Rental.rentalId
where tagNo = 'EK18LT00002' ;

UPDATE Rental
SET Rental.RealReturnDate = '2018-11-12', Rental.Reason = ''
FROM PC inner join Rental
on  PC.rentalId = Rental.rentalId
where tagNo = 'EK18LT00002';

COMMIT
