Detailed Description

Crud operations on tables.

Classes declared here represent CRUD operations on a table. They are analogous to collection CRUD operation classes defined in collection_crud.h.

The following classes for table CRUD operations are defined:

• TableInsert
• TableRemove
• TableSelect
• TableUpdate

CRUD operation objects can be created directly, or assigned from result of DevAPI methods that create such operations:

TableInsert  insert_op(table);
TableSelect  select_op = table.select(...).orderBy(...);

CRUD operation objects have methods which can modify the operation before it gets executed. For example TableInsert::values() appends a row to the list of rows that should be inserted into a table by the given TableInsert operation. These methods can be chained as allowed by the fluent API grammar.
