java.sql.ResultSetMetaData UploadedTableData.getMetaData()

The metadata for the UploadedTableData instance.

The metadata is a standard java.sql.ResultSetMetaData instance.

If you want the ResultSetMetaData to contain column name information, you must specify the client option to send column names.

Consult your Java Software Development Kit documentation for more information about java.sql.ResultSetMetaData.

For more information about column names for DBMLSync and UltraLite, see SendColumnNames (scn) extended option and Send Column Names synchronization parameter.

For more information about direct row handling, see Direct row handling.

For more information about the handle_UploadData connection event, see handle_UploadData connection event.

The following example obtains a java.sql.ResultSetMetaData instance for an uploaded table named remoteOrders. The code uses the ResultSetMetaData.getColumnCount and getColumnLabel methods to compile a list of column names.

import ianywhere.ml.script.*;
import java.sql.*;

// The method used for the handle_UploadData event.
public void HandleUpload(UploadData ut) {
    throws SQLException, IOException
{
    // Get an UploadedTableData instance representing the remoteOrders table.
    UploadedTableData remoteOrdersTable = ut.getUploadedTableByName("remoteOrders");

    // get inserts uploaded by the MobiLink client
    java.sql.ResultSet rs = remoteOrdersTable.getInserts();

    // Obtain the result set metadata.
    java.sql.ResultSetMetaData md = rs.getMetaData();
    String columnHeading = "";

    // Compile a list of column names.
    for (int c=1; c <= md.getColumnCount(); c += 1) {
        columnHeading += md.getColumnLabel( c );

        if (c < md.getColumnCount()) {
            columnHeading += ", ";
        }
    }
    //...
}

In this case, a method named HandleUpload handles the handle_UploadData synchronization event.
