Still used the old way SELECT COUNT(*) to get total number of records stored in a table?
If you are using HANA database, there is another approach to achieve the same.
In HANA there is a metadata table m_tables which stores the related information:
You can find its definition in SAP help.
You can use the following ABAP code to access this HANA table from ABAP server:
class CL_CRM_HOME_TABLE_SIZE_TOOL definition
public

create public .

TYPES: BEGIN OF ty_size,
table_name TYPE char256,
record_count TYPE int4,

END OF ty_size.
TYPES: tt_size TYPE TABLE OF ty_size with key table_name.
