[edit] Tail recursion irrelevant here
The brief discussion of tail recursion is probably off the point and confusing to readers in database art. SQL was created as a means of specifying relational operators: project, select, join, etc. Looping and recursion are not necessary to the relational algebra, hence i.m.h.o. the discussion should skip the un-programmatic aspects of SQL and dive directly into the programmatic features of PL/SQL. --Anonymous —Preceding unsigned comment added by Wernher (talk • contribs) 19:03, October 27, 2004

I agree as well. I've been using PL/SQL many years and never had to (or wanted to) know about "tail recursion". What about putting in a an expanded section on procedure Exception Handling? That would be really good info IMHO. Wam067 (talk) 03:04, 26 March 2008 (UTC)
[edit] Advance or Advanced Data Type
Is it "Advance" or "Advanced" Data Type? --Ernst de Haan —Preceding unsigned comment added by Ernstdehaan (talk • contribs) 11:51, April 11, 2006

[edit] Ada connection
"Its syntax strongly resembles that of Ada"
Actually its syntax superficially reminds you of Ada, but everything that made Ada an interesting language has been ripped out. It could just as easily have Pascal, C or even Basic syntax, for all the relevance it has to ADA.
Interestingly enough, PL/SQL is usually implemented by interpreting a byte code. The only native PL/SQL compiler works by first translating into C.
There's also an alternative language, ProC, which is a pre-processed C that allows similar embedding of SQL. —Preceding unsigned comment added by 129.113.245.64 (talk • contribs) 19:48, April 17, 2007
ADDITION : Claiming that it was based on ADA made it an easier sell to the USA Department of Defence (DOD). (By GrandPoohBah 28-Oct-2007)
[edit] First Appearance in Database
Im confused about the first appearance of PLSQL in the database. On many web sites PLSQL is listed as being introduced in Oracle Database v6. However procedures, functions, packages and triggers were first made available in Oracle v7, not v6 ! Can someone please clarify why PLSQL is often listed as appearing in v6 ? How could PLSQL be executed in v6 ? Did you have to use OCI or SQL*Plus or some other means ?
PLSQL was included in Oracle Forms v3 around the same time frame as database v6, however it had its own PLSQL engine and did not send the PLSQL code to the database to be execute (despite Oracle marketing and sales often implying that it did)
