Altering a table

The c-treeDB alter table function was designed and implemented to allow the modification of table, field and index properties after a table was created, and possibly already populated with data.

The usual steps to perform an alter table are:

• Add, insert, delete or edit fields
• Add, edit or delete indexes
• Alter the table by calling CTTable::Alter() method
