Answer / mr.perfect

IF field is having empty in table , then we can reduce or
increase the size of the field, using the alter statement .
i.e . alter table <tablename>
modify <new columnname ><data type><new size>
if the data in the table is non-empyt, then we cannot alter
the table. better to delete the column and add the same
column to new size.

Answer / rahul

If table is empty then we alter this column to any length,
but if some data got inserted into the table then we can
also decrease the column length upto largest data size
available in that perticulat column.
