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. 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 want to use parameter 2). If you use named parameters, you can specify any subset of the parameters in any order.

None.

The MobiLink server executes this event after receiving everything from the MobiLink client that is required to begin synchronization.

The begin_synchronization script is useful for maintaining statistics. This is because the end_synchronization script is invoked even if there is an error or conflict, so while the upload transaction is rolled back, things like statistics are maintained.

• Script parameters
• Adding and deleting scripts
• end_synchronization connection event
• begin_synchronization table event
• Remote IDs and MobiLink user names in scripts

You may want to store the username value in a temporary table or variable if you want to reference that value many times in subsequent scripts.

CALL ml_add_connection_script ( 
  'version1', 
  'begin_synchronization', 
  'set @EmployeeID = {ml s.username}' );

The following call to a MobiLink system procedure registers a Java method called beginSynchronizationConnection as the script for the begin_synchronization connection event when synchronizing the script version ver1.

CALL ml_add_java_connection_script( 
 'ver1',
 'begin_synchronization',
 'ExamplePackage.ExampleClass.beginSynchronizationConnection'
)

The following is the sample Java method beginSynchronizationConnection. It saves the name of the synchronizing user for later use.

package ExamplePackage; 
public class ExampleClass {
  String _curUser = null;
public String beginSynchronizationConnection(
  String user ) {  
  _curUser = user;
  return ( null );
}

The following call to a MobiLink system procedure registers a .NET method called BeginSync as the script for the begin_synchronization connection event when synchronizing the script version ver1.

CALL ml_add_dnet_connection_script( 'ver1',
  'begin_synchronization',
  'TestScripts.Test.BeginSync'
)

The following is the sample .NET method BeginSync. It saves the name of the synchronizing user for later use.

namespace TestScripts {
public class Test {
  string _curUser = null;     
public string BeginSync( 
  string user ) { 
  _curUser = user;
  return ( null );
}}}
