Having more than 50 column in a SQL table

Question

I have designed my database in such a way that One of my table contains 52 columns. All the attributes are tightly associated with the primary key attribute, So there is no scope of further Normalization.

Please let me know if same kind of situation arises and you don't want to keep so many columns in a single table, what is the other option to do that.

Answer 1

It is not odd in any way to have 50 columns. ERP systems often have 100+ columns in some tables.

One thing you could look into is to ensure most columns got valid default values (null, today etc). That will simplify inserts.

Also ensure your code always specifies the columns (i.e no "select *"). Any kind of future optimization will include indexes with a subset of the columns.
