Sunny, in SQLPlus you can use substitution variables such as &empid and you will be prompted at run time for the value of the variable. See the SQLPlus accept command for a more user friendly way of prompting.

Within pl/sql you can just define and reference a variable such as v_empid and reference the pl/sql variable in the query: where empid = v_empid. Obviously you would need to supply v_empid with a value prior to using it.

>From a pro* language such as proc*c you would declare a variable and
then prefix it with a ":" so the variable would be :v_empid

Like Hans said it depends on the tool.
