We have "alter table" syntax from Oracle to add data columns in-place in this form:
alter table table_name add ( column1_name column1_datatype column1_constraint, column2_name column2_datatype column2_constraint, column3_name column3_datatype column3_constraint ); Here are some examples of Oracle "alter table" syntax to add data columns. alter table cust_table add cust_sex varchar2(1) NOT NULL; Her is an example of Oracle "alter table" syntax to add multiple data columns. ALTER TABLE cust_table ADD ( cust_sex char(1) NOT NULL, cust_credit_rating number ); |
