Hi there,
I am still struggling with following problem:
There are two tables in mysql
1. city fields: ID, countryid, provinceid, city
containing 2.5 million entries.
2. province fields: ID, countryid, provinceid, provincename
Now there are some cities without a valid province id in the other table.
Means that those city do not find the right province name.
I would like to:
1. delete those province rows (all belonging to this country) in the
province table
2. set the province_id to "" in the city table.
Seems to be complicated.. maybe someone could give me a hint on this
Thanx, Andy
