Answer / madhuri
SQL is a structured query language used for various
operations such as retrieval,manipulation of data using
DML,DDL statements.
PL/SQL is programming language used to write various sql
statements together.Advantage of pl/sql over sql is,you can
write many sql statements within a pl/sql block.One more
advantage is subprogramming like procedures and functions.
We can write cursors for fetching number of records at a time.
And also packages and triggers.
Embedded sql are those statements which are written in host
programs like pro*c,java etc.
