Assume you use the following table to log synchronization events on the remote database.

CREATE TABLE SyncLog
(
 "event_id"          INTEGER NOT NULL DEFAULT AUTOINCREMENT ,
   "event_name"       VARCHAR(128) NOT NULL ,
   "ml_user"            VARCHAR(128) NULL ,
   "event_time"         TIMESTAMP NULL,
   "table_name"         VARCHAR(128) NULL ,
   "upsert_count"       VARCHAR(128) NULL ,
   "delete_count"       VARCHAR(128) NULL ,
   "exit_code"          INTEGER NULL ,
   "status_retval"      VARCHAR(128) NULL ,
   "pubs"                VARCHAR(128) NULL ,
   "sync_descr "         VARCHAR(128) NULL , 
    PRIMARY KEY ("event_id"),
);

The following example logs the MobiLink user, the table name and the number of inserted or updated rows immediately after a table is downloaded.

CREATE PROCEDURE sp_hook_dbmlsync_download_table_end()
BEGIN
    -- declare variables   
    DECLARE tbl VARCHAR(255);
    DECLARE upsertCnt VARCHAR(255);
    DECLARE deleteCnt VARCHAR(255);

    -- load the table name from #hook_dict 
    SELECT #hook_dict.value
     INTO tbl
     FROM #hook_dict
     WHERE #hook_dict.name = 'table name';

    -- load the upsert count from #hook_dict 
    SELECT #hook_dict.value
     INTO upsertCnt
     FROM #hook_dict
     WHERE #hook_dict.name = 'upsert count';

    -- load the delete count from #hook_dict 
    SELECT #hook_dict.value
     INTO deleteCnt
     FROM #hook_dict
     WHERE #hook_dict.name = 'delete count';

    INSERT INTO SyncLog (event_name, ml_user, table_name,
      upsert_count, delete_count, event_time)
     SELECT 'download_table_end', #hook_dict.value, tbl,
      upsertCnt, deleteCnt, CURRENT TIMESTAMP
     FROM #hook_dict
     WHERE name = 'MobiLink user' ; 
END;
