I have a customer table from a bank box. There are different fields, such as Identifier, User_Code, User_Name, User_Current ... I have to modify a field of four different clients but they belong to the same table:
update miTabla
set Fec_Anulación = '26/03/2018 18:00'
where Cod_usuario in ('u251', 'u252', 'u253', 'u254')
but I do not know if the where statement gives me an error. Can you give me a cable? Thanks in advance
