Oracle Add Column: Insert in Middle of Table

To add a column in the middle of a table, you can use the ALTER TABLE statement. For example, to add a column at a specific position in the middle of a table, you can use the following syntax:

ALTER TABLE table_name
ADD column_name datatype AFTER existing_column_name;

In this syntax, table_name represents the name of the table, column_name represents the name of the column to be added, datatype represents the data type of the column, and existing_column_name refers to the name of the existing column where the new column will be added after. By specifying the AFTER keyword, you can indicate which existing column the new column will be added after.

For example, to add a new column named birthday after the hire_date column in a table called employees, you can use the following statement:

ALTER TABLE employees
ADD birthday DATE AFTER hire_date;
