Functionality

The public class methods MODIFY_DB_FROM_DATA, DELETE_DB_FROM_DATA and READ_DATA_FROM_DB of the class/FRE/DB_CL_TS_COMPRESS are called by handlers who need to process large internal tables in the database in a compressed manner.

The interfaces for the write method, delete method and read method are generic; that is, the types of the imported parameters are specified at runtime.

Due to this generic approach, at runtime the caller can specify the type of table to be saved and thestructures containing its header key and attribute fields. If suitable, the caller can also differentiate the database tables using a generic splitting structure.

Relationships

Example

If a caller is of class /FRE/DB_CL_TS_CDM, that class handles the planning data.

Notes

• The table parameter defines the database table in which the datasets are saved.

• If the table parameter structure or the table parameter value changes between two calls of the write method, a new table is defined.

• If the key parameter structure changes between an initial call of the write method and one or more consecutive calls of the read method, an error occurs each time.

• The attribute parameters must also have the same type as in the first call of the MODIFY_DB_FROM_DATAmethod within all consecutive calls of the write method and the read method, otherwise an exception is raised. The values, however, can differ.
