I have a table that has a problem name field and a Jurisdiction name field. I want to search for multiple problem names that fall under the same Jurisdiction name.
SELECT TOP (100000) [Master_Incident_Number]
,[Response_Date]
,[Problem]
,[Location_Name]
,[Address]
,[Apartment]
,[City]
,[Jurisdiction]
,[MethodOfCallRcvd]
,[Call_Disposition]
,[CallTaking_Performed_By]
,[CallClosing_Performed_By]
FROM [Reporting_System].[dbo].[Response_Master_Incident]
where Jurisdiction like 'Sector 5%'
and Response_Date >= '2022-01-01 00:00:00.000'
and Problem like 'Building / Security Check-LCL'
or Problem like 'Park and Walk-LCL'
When I run this I get returns that don't match what I put in for the Jurisdiction like 'Sector 5%'". How can I get it to only return items with the "Jurisdiction like" field being 'Sector 5%' only.
If I only do a search for only one problem name type, the search works and only returns Jurisdictions with the name like "Sector 5". But If I add an additional problem name type it returns all Jurisdiction Names with those 2 problem name types.

It's always the OR condition in these cases. Operator precedence here doesn't work the way you think it should. You need parentheses:
where Jurisdiction like 'Sector 5%'
and Response_Date >= '2022-01-01 00:00:00.000'
and (Problem like 'Building / Security Check-LCL'
or Problem like 'Park and Walk-LCL')
But since there are no wildcards in either of those checks, we can also simplify it like this:
where Jurisdiction like 'Sector 5%'
and Response_Date >= '2022-01-01 00:00:00.000'
and Problem IN ('Building / Security Check-LCL','Park and Walk-LCL')
