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 MobiLink server executes this event as the first step in the processing of uploaded rows. Uploaded rows are processed in a separate transaction. The execution of this event is the first table-specific action in this transaction.

You can have one begin_upload script for each table in the remote database. The script is only invoked when the table is actually synchronized.

• Script parameters
• Script additions and deletions
• end_upload table event
• begin_upload connection event
• Remote IDs and MobiLink user names in scripts

When uploading rows from a remote you may want to place the changes in an intermediate table and manually process changes. You can delete from a global temporary table in this event, in preparation for receiving the new rows.

CALL ml_add_table_script( 
 'version1', 
 'Leads',
 'begin_upload', 
 'DELETE FROM T_Leads' )

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

CALL ml_add_java_table_script( 
  'ver1',
  'table1',
  'begin_upload',
  'ExamplePackage.ExampleClass.beginUploadTable'
 )

The following is the sample Java method beginUploadTable. It prints a message to the MobiLink message log. (Printing a message 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 beginUploadTable( 
  String user, 
  String table ) {
  java.lang.System.out.println("Beginning to process upload for: " + table);
  }

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

CALL ml_add_dnet_table_script(
  'ver1', 
  'table1', 
  'begin_upload',
  'TestScripts.Test.BeginTableUpload'
)

The following is the sample .NET method BeginTableUpload. It prints a message to the MobiLink message log. (Printing a message 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 BeginTableUpload(
  string user,
  string table ) {  
  System.Console.WriteLine("Beginning to process upload for: " + table);
  }}}
