 query and stored procedures I'm so totally new to postgresql that I'm not sure how to word this. I want to create a query, that does two things 1) take input in the form of a string of numbers, and test if a) is ssn b) or internal id if the string is an ssn, make a second query to another data base, asking it to convert the ssn to our internal id otherwise, 2) use the id given to query an existing table I'm not sure what feature/function postgresql has to help me do this. I'd like to stick with using python as my language, and I'm guessing this would be stored procedure, but I'm too new to know. Please point me to some good reading. -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing" ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend      |
