Reply with quote

Hi,

I have a query on primary key. I have a table, which is having more than one primary key.

I mean there are 4 columns with primary key out of 76 columns in the table.

in that four columns any column can have the same data multiple times, but if we combine all these 4 columns then the data will be unique.

If it is the case, what we call this group of columns.

thanks in advance
