How can we change the name of a column of a table?..

Answer / nithya

changing a column name differs from the type of database we use.

MySQL:
ALTER table customer CHANGE Address Addr char(50);

Oracle:
ALTER table customer RENAME COLUMN Address TO Addr;

SQL Server:
It is not possible to rename a column using the ALTER TABLE
statement in SQL Server. Use sp_rename instead.
