procedural language sql.difference is in pl/sql we can work

predefined structure. but sql does not have.

Answer / antu

SQL is a data oriented language for selecting and
manipulating sets of data. PL/SQL is a procedural language
to create applications. You don't normally have a "SQL
application". You normally have an application that uses SQL
and a relational database on the back-end. PL/SQL can be the
application language just like Java or PHP can. SQL may be
the source of data for your screens, web pages and reports.
PL/SQL might be the language you use to build, format and
display those screens, web pages and reports.

Think of it like this: The code that makes your program
function is PL/SQL. The code that manipulates the data is
SQL DML. The code that creates stored database objects is
SQL DDL. DDL compiles the code that is written in PL/SQL.
PL/SQL may call SQL to perform data manipulation. The
commands that format the output of a tool are not related to
the SQL standard or to PL/SQL.

data from the database. Before 1974 it is known as Gupta

Though it is structured quer language it is un structured
its like simple english language.

Answer / tushar matere

SQL is a structured query language.
Actually SQL is a set of rules defined by mr.Codd.
Any database like oracle,derby or sybase has to follow
these rules.We can say that database following maximum
codd's rule(there are 12 rules) is better than other like
oracle follows 11 rule so it is better than other.

there are different categories in SQL
MySql-->supports triggers and cursors
Pl/Sql-->supports procedures.
Tl/Sql-->supports transactions.
MSSql-->it is microsoft version of SQL.

Answer / dinesh joshi

1)SQL is executed one statement at a time. PL/SQL is
executed as a block of code.
2)SQL tells the database what to do (declarative), not how
to do it. In contrast, PL/SQL tell the database how to do
things (procedural).
3)SQL is used to code queries, DML and DDL statements.
PL/SQL is used to code program blocks, triggers, functions,
procedures and packages.
4)You can embed SQL in a PL/SQL program, but you cannot
embed PL/SQL within a SQL statement.
