Navigation with the Table API

UltraLite for M-Business Anywhere provides you with many methods to navigate a table to perform a wide range of navigation tasks.

The following methods of the ULTable object allow you to navigate your result set:

  • moveAfterLast   moves to a position after the last row.

  • moveBeforeFirst   moves to a position before the first row.

  • moveFirst   moves to the first row.

  • moveLast   moves to the last row.

  • moveNext   moves to the next row.

  • movePrevious   moves to the previous row.

  • moveRelative   moves a certain number of rows relative to the current row. Positive index values move forward in the table, negative index values move backward in the table, and zero does not move the cursor. Zero is useful if you want to repopulate a row buffer.


The following code opens the customer table and scrolls through its rows. It then displays an alert with the last name of each customer.

var tCustomer;
tCustomer = conn.getTable( "customer", null );;
While (tCustomer.moveNext()) {
  alert( tCustomer.getString(3) );
Specifying an index

You expose the rows of the table to the application when you open the table object. By default, the rows are exposed in order by primary key value, but you can specify an index to access the rows in a particular order.


The following code moves to the first row of the customer table as ordered by the ix_name index.

tCustomer = conn.getTable("customer", null );
