Joins in SQL

I have a table, which contains several fields, which can have a value of 1,2,3 or 4.  I have created another table which has the entries.

1 Large
2 Medium
3 Small
4 None

I would like to construct a query which searches the first table, but instead of outputing 1,2,3 or 4, Large, Medium, Small are outputted.. how can I do this?

RE: Joins in SQL

For a simple example, say TblA has ColA and ColB.  ColB is the field with 1, 2, 3, or 4.  Then TblC has ColC and ColD, where ColC is 1, 2, 3, or 4, and ColD is Large, Medium, Small, and None.

Then construct your query like this:

Select ColA, ColD
From TblA, TblB
Where TblA.ColB = TblC.ColC

For multiple columns in TblA with the same values, it becomes more difficult.  To make it easy on myself, I do multiple queries, or have multiple tables but I know that is not really the most efficient use of computer memory.
