Question

I trying to figure out how I can delete from multiple tables in SQL Server.

I have one table containing only one primary key and three foreign keys for the three table I want to delete from. The other three table does not contain any foreign keys.

The stored procedure have one parameter, a specific primary key from one of the tables. I want to delete from the other tables WHERE tableID = @tableID. The constraints between the tables are set to cascade.

Is it possible with only that parameter to delete from all four tables?

I’ve tried with inner join, outer join, temptable..

Table      Table        Table      Table 
Pk         Pk(Fk1)      Pk(Fk2)    Pk(Fk3)
Fk1        Column       Column     Column
Fk2        Column       Column     Column
Fk3

I have the table 2 Pk as parameter.

Answer 1

if your foreign keys were created with DELETE CASCADE, once you delete from the main table, all the related rows on the foreign tables will be delete too.

It seems like this is how it is configured, isnt it working?
