Hi everyone,
I am getting this error:

Msg 512, Level 16, State 1, Line 1
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.

please help, I have tried to solve it on my own but still can't find the right answer..
this is the query:

update tbl_M_MasterLogs set rptprobtype =
(Select [Problem Type]
from tbl_rpt_MasterData
where tbl_M_MasterLogs.CaseNo = tbl_rpt_MasterData.CaseNo)

Thank you very much in advance!

TOP 1 gives you only one result. Your sub query returned more that one result thus the error.

Add TOP 1 to sub query is my quick answer.

SQL

update tbl_M_MasterLogs set rptprobtype =
(Select TOP 1 [Problem Type]
from tbl_rpt_MasterData
where tbl_M_MasterLogs.CaseNo = tbl_rpt_MasterData.CaseNo)

The other way would be

SQL

update tbl_M_MasterLogs 
set rptprobtype = tbl_rpt_MasterData.[Problem Type] 
FROM tbl_M_MasterLogs 
INNER JOIN tbl_rpt_MasterData
ON tbl_M_MasterLogs.CaseNo = tbl_rpt_MasterData.CaseNo)
