    Re: composite data type

    Composite data types are exactly like "Struct" data type in C. You can group logically related different data variable together...

    Re: composite data type

    collections are called as composite datatypes like varray,record,nested tables.
    examples u can write on ur own by using all the above.
    syntax :
    type typename is record(.....)
    type typename is table of(..) index by binary_integer

    INDEX BY:-can hav multiple rows and column
    We use it to handle more than one values at a time
    THESE ARE USED MAINLY IN PL/SQL

    Re: composite data type

    Hi,
    in pl/sql we have two types of datatypes
    1. scalar
    2. composite.

    In scalar u can store only one value at a time and
    ex is a number(10),name char(1) etc.

    WHile in Composite u can store whole row mean if one row have 3 columns so u can store 3 values in a composite datatype variable at a time.
    Ex. emp employees%rowtype ;
    Mean if enployees have 3 columns so in variable emp u can store 3 values of 3 columns at a time .
    Hope u Got .
    Bye.
