Processes statements related to a specific table just after applying deletes uploaded from the specified table in the remote database.

Parameters

In the following table, the description provides the SQL data type. If you are writing your script in Java or .NET, you should 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, but 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 want to use parameter 2). If you use named parameters, you can specify any subset of the parameters in any order.

SQL example

You can use this event to process rows deleted during the upload on an intermediate table. You can compare the rows in the base table with rows in the intermediate table and decide what to do with the deleted row.

The following call to a MobiLink system procedure assigns the EndUploadDeletesLeads stored procedure to the end_upload_deletes event.

CALL ml_add_table_script(
  'version1',
  'Leads',
  'end_upload_deletes',
  'call EndUploadDeletesLeads()');

The following SQL statement creates the EndUploadDeletes stored procedure.

CREATE PROCEDURE EndUploadDeletesLeads ( )
Begin
  FOR names AS curs CURSOR FOR
  SELECT LeadID
    FROM Leads
    WHERE LeadID NOT IN (SELECT LeadID FROM T_Leads);
  DO
   CALL decide_what_to_do( LeadID );
  END FOR;
end
Java example

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

CALL ml_add_java_table_script(
   'ver1',
   'table1',
   'end_upload_deletes',
   'ExamplePackage.ExampleClass.endUploadDeletes' )

Following is the sample Java method a endUploadDeletes. It calls a Java method that manipulates the database.

public String endUploadDeletes( 
  String user,
  String table )
  throws java.sql.SQLException {
  processUploadedDeletes( _syncConn, table );
  return ( null );
}
.NET example

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

CALL ml_add_dnet_table_script(
   'ver1',
   'table1',
   'end_upload_deletes',
   'TestScripts.Test.EndUploadDeletes'
)

Following is the sample .NET method a EndUploadDeletes. It calls a .NET method that manipulates the database.

public string EndUploadDeletes( 
  string user, 
  string table ) {
  processUploadedDeletes( _syncConn, table );
  return ( null );
}
