In the following table, the description provides the SQL data type. If you are writing your script in Java or .NET, use the appropriate corresponding data type. See SQL-Java data types and SQL-.NET data types.

In SQL scripts, you can specify event parameters by name or with a question mark. Using question marks has been deprecated and it is recommended that you use named parameters. You cannot mix names and question marks within a script. If you use question marks, the parameters must be in the order shown below and are optional only if no subsequent parameters are specified (for example, you must use parameter 1 if you are going to use parameter 2). If you use named parameters, you can specify any subset of the parameters in any order.

None.

The upload_statistics event allows you to gather, for any user, vital statistics on synchronization happenings as they apply to any table. The upload_statistics table script is called just before the commit at the end of the upload transaction.

• Script parameters
• Script additions and deletions
• download_statistics connection event
• upload_statistics connection event
• upload_statistics table event
• synchronization_statistics connection event
• synchronization_statistics table event
• time_statistics connection event
• time_statistics table event
• MobiLink Profiler
• Remote IDs and MobiLink user names in scripts

The following example inserts a row into a table used to track upload statistics.

CALL ml_add_connection_script(
 'ver1',
 'upload_statistics',
 'INSERT INTO my_upload_statistics ( 
   user_name, 
   table_name, 
   num_warnings, 
   num_errors, 
   inserted_rows, 
   deleted_rows, 
   updated_rows,
   conflicted_updates, 
   ignored_inserts,
   ignored_deletes, 
   ignored_updates, bytes,
   deadlocks )
  VALUES( 
   {ml s.username}, 
   {ml s.table}, 
   {ml s.warnings}, 
   {ml s.errors}, 
   {ml s.inserted_rows}, 
   {ml s.deleted_rows}, 
   {ml s.updated_rows}, 
   {ml s.conflicted_updates}, 
   {ml s.ignored_inserts}, 
   {ml s.ignored_deletes}, 
   {ml s.ignored_updates}, 
   {ml s.bytes}, 
   {ml s.deadlocks} )'  )

The following example works with an Oracle consolidated database.

CALL ml_add_connection_script(
 'ver1',
 'upload_statistics',
 'INSERT INTO upload_tables_audit (
  id,
  user_name,
  table,
  warnings,
  errors,
  inserted_rows,
  deleted_rows,
  updated_rows,
  conflicted_updates,
  ignored_inserts,
  ignored_deletes,
  ignored_updates, 
  bytes, 
  deadlocks )
 VALUES ( 
   ut_audit.nextval,
   {ml s.username}, 
   {ml s.table}, 
   {ml s.warnings}, 
   {ml s.errors}, 
   {ml s.inserted_rows}, 
   {ml s.deleted_rows}, 
   {ml s.updated_rows}, 
   {ml s.conflicted_updates}, 
   {ml s.ignored_inserts}, 
   {ml s.ignored_deletes}, 
   {ml s.ignored_updates}, 
   {ml s.bytes}, 
   {ml s.deadlocks} )' )

Once statistics are inserted into the audit table, you may use these statistics to monitor your synchronizations and make optimizations where applicable.

The following call to a MobiLink system procedure registers a Java method called uploadStatisticsTable as the script for the upload_statistics table event when synchronizing the script version ver1.

CALL ml_add_java_table_script(
  'ver1',
  'table1',
  'upload_statistics',
  'ExamplePackage.ExampleClass.uploadStatisticsTable' )

The following is the sample Java method uploadStatisticsTable. It logs some statistics to the MobiLink message log. Logging statistics to the MobiLink message log might be useful at development time but would slow down a production server.)

package ExamplePackage; 
public class ExampleClass {
  String _curUser = null;
public void uploadStatisticsTable(
  String user,
  String table,
  int warnings,
  int errors,
  int insertedRows,
  int deletedRows,
  int updatedRows,
  int conflictedInserts,
  int conflictedDeletes,
  int conflictedUpdates,
  int ignoredInserts,
  int ignoredDeletes,
  int ignoredUpdates,
  int bytes,
  int deadlocks ) {
  java.lang.System.out.println( "updated rows: " +
    updatedRows ); 
  }

The following call to a MobiLink system procedure registers a .NET method called UploadTableStats as the script for the upload_statistics table event when synchronizing the script version ver1 and the table table1.

CALL ml_add_dnet_table_script(
  'ver1',
  'table1',
  'upload_statistics',
  'TestScripts.Test.UploadTableStats'
)

The following is the sample .NET method uploadStatisticsTable. It logs some statistics to the MobiLink message log. (Logging statistics to the MobiLink message log might be useful at development time but would slow down a production server.)

namespace TestScripts {
public class Test {
  string _curUser = null;
public void UploadTableStats(
  string user,
  string table,
  int warnings,
  int errors,
  int insertedRows,
  int deletedRows,
  int updatedRows,
  int conflictInserts,
  int conflictDeletes,
  int conflictUpdates,
  int ignoredInserts,
  int ignoredDeletes,
  int ignoredUpdates,
  int bytes,
  int deadlocks ) {
  System.Console.WriteLine( "updated rows: " +
    updatedRows );
  }}}
