sql - C# Access Database Question -
say have 2 tables now, priceplan , bill. both tables have column called 'price' , table 'bill' update value 'priceplan's price. how can or sql statement should using? in advance!
you need have sort of way define relationship between 2 tables.
for instance if tables have structure:
priceplan --------- id price bill --------- priceplanid price
this work sql server. see below access solution.
then query should update bill :
update b set b.price = pp.price bill b inner join priceplan pp on b.priceplanid = pp.id
also, schema above example purposes. if yours should @ changing it.
update
i noticed access, sorry. strucure of query different. see below:
update bill inner join priceplan on bill.priceplanid = priceplan.id set bill.price= [priceplan].[price];
