- Reader Stream, Read Database Table

This example demonstrates how data can be read from a DDIC database table using a reader stream.

Source Code

Execute

Description

In the method main, a reference variable reader is declared for a reader stream. This reader stream is then created in a SELECT statement.

The internal table pict is then filled iteratively with binary data from the row found. If data previously written in the executable writer stream example is read, this is the data of a figure in the GIF format.

The auxiliary method show_picture displays the figure in an HTML browser.
