    | { WRITER|LOCATOR } ... 

Effect

These additions define the static type of the LOB handle components when deriving a LOB handle structure using the statement TYPES.

• The addition READER defines the following:
  

• The static type CL_ABAP_DB_X_READER for BLOBs

• The static type CL_ABAP_DB_C_READER for CLOBs

• The addition WRITER defines the following:
  

• The static type CL_ABAP_DB_X_WRITER for BLOBs

• The static type CL_ABAP_DB_C_WRITER for CLOBs

• The addition LOCATOR defines the following:
  

• The static type CL_ABAP_DB_X_LOCATOR for BLOBs

• The static type CL_ABAP_DB_C_LOCATOR for CLOBs

• The addition LOB HANDLE defines the following:
  

• The static type IF_ABAP_DB_BLOB_HANDLE for BLOBs

• The static type IF_ABAP_DB_CLOB_HANDLE for CLOBs

The additions READER and WRITER cannot be used together in the statement TYPES. Furthermore, WRITER cannot be used with LOB HANDLE.

The combination options with the columns lob_handle_columns, when specified, are explained in the statement TYPES.

Example
