In the following example, we filter out positive values. We have a slice of integers. We create a new slice from the existing one having only its positive values. We go over the elements of the array with a for loop. We test each element if it is greater than zero. All the elements that satisfy the condition are copied to the new positive

slice.

A new record is started with NextRecord. INTRODUCTION TO SQLITE VISUAL BASIC The DataSet object is used for offline work with a mass of data. It is a disconnected data representation that can hold data from a variety of different sources.
