Talk:PL/SQL

message: 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

:Agree that a discussion of recursion may be overkill for this article, but disagree as to the reason. The whole point of the language is to add procedural elements like conditionals (IF, CASE) and looping to what is otherwise a non-procedural language. It's trivial to use a PL/SQL collection datatype to implement a basic stack for recursion, if a recursive algorithm is desired. BWatkins (talk) 03:27, 4 October 2011 (UTC)
thread_title: Tail recursion irrelevant here

message: "Its syntax strongly resembles that of Ada"
Oracle Database PL/SQL Language Reference as of version 21c (2022) states: "PL/SQL is based on the programming language Ada." (Doubtless there are other languages with similarities to Ada and PL/SQL.)
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

:I can fully believe that it is based on Ada, as both Ada and PL/SQL strongly remind me of PL/1. Are there any sources on the PL/SQL <-> PL/1 connection?Mzk1 (talk) 06:54, 8 August 2011 (UTC)
replies: text: I really, really believe that I heard many years ago that Oracle is using a variation of PL/1 and Oracle's connection to IBM's DB2 supports the idea that Oracle was influenced by IBM. Note that PL/1 existed for more than a decade before Ada was released. Sam Tomato (talk) 01:53, 13 November 2016 (UTC)

thread_title: Ada connection

message: 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)

message: At present the History section uses only Oracle release numbers as a time references.  I think it would be helpful to have calendar years cited as well, for those who do not measure time as against Oracle benchmarks... :)

thread_title:  History - Features 

message: Pragmas, control flow, automatic rollbacks and probably other issues make exceptions relatively complex to handle elegantly. Maybe some real-life examples could be added to show how to use it. All in all, maybe it deserves a separate section?

message: I don't know anything about PL/SQL and very little about SQL itself.  However, I used to be a proficient PL/1 programmer, and I have no problem reading and mostly understanding the PL/SQL code samples.  — Preceding unsigned comment added by 76.102.116.97 (talk) 16:27, 15 May 2018 (UTC)
thread_title:  Is PL/1 the model for PL/SQL 

message: I see there was a separate page for StepSqlite that was merged into this one. I was curious about it and went looking around but the product seems to be defunct; should the reference to it be removed so as to save others from a wild goose chase?  — Preceding unsigned comment added by 107.195.167.115 (talk) 21:52, 12 October 2020 (UTC)
