Question

I am having an issue when trying to submit two inserts at once. The table has a auto increment primary key. The comment objects set up dont have there ID value set so that the database can assign this.

My code works for single inserts if i submit straight away but if i try and do multiple InsertOnSubmit commands then it seems to do nothign, and returns no errors or exceptions even though my code is within a try and catch block. Has anyone else had this problem or do you know which direction i should be looking?

Example 1 (This doesn’t commit to the database)

//myComment is initialised with data
dc.tblDailyComments.InsertOnSubmit(myComment);


//myComment2 is initialised with different data
dc.tblDailyComments.InsertOnSubmit(myComment2); 


//when this is called it does not commit to the database   
dc.SubmitChanges();

Example 2 (This works fine)

//myComment is initialised with data
dc.tblDailyComments.InsertOnSubmit(myComment);

//commits to the database   
dc.SubmitChanges();

//myComment2 is initialised with different data
dc.tblDailyComments.InsertOnSubmit(myComment2); 


//commits to the database   
dc.SubmitChanges();
