Hi Lynn,

Are database column types covered in the book? If so, I would think that they would be very RDBMS-specific (Oracle vs MySQL vs MSSQL vs etc). Do you explain then the differences among some of them?

Thanks.

You are aware that there are ANSI standards for datatypes which all good relational databases implement?

Indeed, column types between database flavors are very similar. There are some syntactical and structural differences, but once you understand how to use, say, a variable character text data type, then the actual DBMS syntax can be looked up.
