Example

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 compiles a list of publications. It logs the list of publications and other synchronization information at the beginning of the download stage of the synchronization. 

CREATE PROCEDURE sp_hook_dbmlsync_download_begin ()
BEGIN
    
    DECLARE pubs_list VARCHAR(1024);
    DECLARE temp_str VARCHAR(128);
    DECLARE qry VARCHAR(128);

-- insert publication list into pubs_list
    SELECT LIST(value) INTO pubs_list
     FROM #hook_dict
     WHERE name LIKE 'publication_%';

-- log publication and synchronization information
    INSERT INTO SyncLog(event_name,ml_user,pubs,event_time)
     SELECT 'dbmlsync_download_begin',#hook_dict.value,
      pubs_list,CURRENT TIMESTAMP
     FROM #hook_dict
     WHERE name='MobiLink user'; 
END;
