Hi, mysql newb here, coming mostly from ms sql server.
I'm wondering how to find out basic info (type, str length, column name if
getting all cols from a list of tables, etc), about a set of columns from a
number of different tables. I'm also interested in getting a list of the
tables in a db.
May I introduce you to the family of SHOW commands?
SHOW DATABASES - lists all databases on a server
SHOW TABLES - lists all tables within your current database
SHOW CREATE TABLE x - returns a table containing a SQL statement you
could use to recreate the table x if you needed to
approve of having to write
applications to get this sort of information, Shawn's approaches are going
to be better for you ;-)

Thanks Shawn, looks like
SHOW TABLES lists tables in a db
DESCRIBE tablename (= SHOW CREATE TABLE tablename) outputs column info,
but your application will have to parse it.
EXPLAIN is for query optimisation analysis, not table column listings.
The manual's pretty clear on these topics.
