I've got the following tables :
Em_table
Em_No nchar(3) Primary key
Em_type nchar(20) , (values it can be inserted into that column are 'P', 'T' and defaults to Work_table(w_type))
.
.
Work_table
w_No ......
w_type nchar(20) values it can be inserted into that column are 'P', 'T' )
.
.
Could you please give me a way to assign the aforementioned default to that column ??
