SQL Server数据库中运行时条目期间的参照完整性约束

Question

Ii have two forms in which data is being added into two tables. One table has a FK which refers to the other table primary key. In the second form I insert values in to the form and want to store it in the db.

I get the following error

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_ StuDetail _eduid__5AA469F6". The conflict occurred in database "Dunstan_DB", table "dbo.EduDetails", column 'eduid'. The statement has been terminated.

How can this be resolved? How do we know during runtime that this value present in parent table as primary key or not?

Answer 1

Within SQL Mangement studio, there is a tool called profiler (may not be in express version) it allows you to see the exact queries that are being sent to the database. However its pretty certain that the value you are sending to the detail table does not contain the pk-fk value in the master table. You need to ensure the master table is inserted to before the detail. Break your program when you are updating / inserting the detail , and simply run the query

Select * from MasterTable WHERE ID = PassedFK
