ESH_S_QL_QLOG is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Query Log Header" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_ESH_S_QL_QLOG TYPE ESH_S_QL_QLOG.
The ESH_S_QL_QLOG table consists of various fields, each holding specific information or linking keys about Query Log Header data available in SAP. These include MANDT (Client), EXEC_ID (Search Execution ID), SESSION_ID (Search Session ID), QUERY_TYPE (Internal Query Type (Sync, Async, Bulk, Delegated))... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
