Chris,
> In my capacity as a vet student, I'm trying to create a database of
antibiotics. The way that I have set it up so far is to have one main table
listing the antibiotics versus their respective efficacies against the four
major groups of bacteria. Due to the way that my PHP frontend works, I have
assigned a number to the efficacy - 1 being excellent and 5 being poor
efficacy against the particular bacterium. However, I now want to have a new
table which converts numbers into words. The problem is this, if I join the
main table with the "translation" lookup table, the column names for each of
the four categories in the main default to the column name in the lookup
table and hence are all the same. What SQL expression should I use to
translate the cryptic numbers into plain english whilst preserving the column
headings in the main table?
Please post your table definitions as SQL statements.
