Select

Hi,

I have two tables one for the city and the second one is for the churches.

what I want to do is to select all the cities that don't have any churches linked to.

here's my data structure.

Table: CityTbl
fields: CityID, CityName, StateID, CityStatus

Table: ChurchTbl
Fields: ChurchID, ChurchName, ChurchStatus, ChCityID

Both tables are linked my CityID and ChCityID

how can I remove all cities that do not have any church linked to?

Thanks,

You can get list of cities that don't have church by :
SELECT CityID, CityName
FROM CityTbl
WHERE CityID NOT IN (SELECT DISTINCT ChCityID FROM ChurchTbl)
0

To delete records write following query :

DELETE FROM CityTbl
WHERE CityID NOT IN (SELECT DISTINCT ChCityID FROM ChurchTbl)
