connection.getConnection() returns nothing makes me feel unfamiliar in the first glance. what do you think if we make the DBConnection() constructor accept connectionString and create actual connection?

yes, that's sounds better, will update it.

instead of DBTable.createTable(DBStatement) or DBTable.populateTable(DBStatement), can we do DBStatement.createTable(DBTable) and DBStatement.populateTable(DBTable) ? to be consistent with actual JDBC code.

Also here, can we do DBStatement.dropTable(DBTable) ? to be consistent with actual JDBC code.
can we also move dropTable() methods into a finally block to make sure table is dropped when test fails.

why we have .trim() for varchar and nvarchar but not for char or nchar?

for char and nchar the trailing space is preserved, so I din't add it. Now that you mention it, do you think they needed for nvarchar and varchar?

To be even I'll remove trim() form both char and varchar

should we throw exception if there is a missing type?

this class is called DBColumns. can we merge it with DBTable? I feel they should be identical.

sounds fair, I'll update it.

just wondering why we need to catch those 2 exceptions? can't we just throw the exceptions?
There was a problem hiding this comment.
It's best practice not to throw generic Exception whenever possible, so I've added individual ones (since its just 2).

I remember we decided to use {} for single line if statement
