In MySQL, the SQL syntax for ALTER TABLE Rename Column is

ALTER TABLE "table_name"
Change "column 1" "column 2" ["Data Type"]

In Oracle, the syntax is,

ALTER TABLE "table_name"
RENAME COLUMN "column 1" TO "column 2"

Let's look at the example. Assuming our starting point is the "customer" table created in the CREATE TABLE section:

Table customer

Column Name	Data Type
First_Name	char(50)
Last_Name	char(50)
Address	char(50)
City	char(50)
Country	char(25)
Birth_Date	date

To rename "Address" to "Addr", we key in,

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.

Resulting table structure:

Table customer

Column Name	Data Type
First_Name	char(50)
Last_Name	char(50)
Addr	char(50)
City	char(50)
Country	char(25)
Birth_Date	date
