You can use Interactive SQL to view BLOB data, as well as images that are less than 5000000 pixels. In addition you can view SVGs and save them to other formats, such as JPEG, PNG, and TIFF.
Supported image formats include: BMP (Windows 95 version), GIF, JPEG, PNG, PNM, SVG, TIFF, and WBMP (wireless bitmap).
Connect to the database. For example, connect to the SQL Anywhere sample database.
Execute a query that returns a result set that contains an image.
For example, run the following to return JPEG images:
SELECT * FROM products;
Run the following to return an SVG image:
SELECT '<?xml version="1.0" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg width="100%" height="100%" version="1.1" xmlns="http://www.w3.org/2000/svg"> <rect width="99" height="99" style="fill:rgb(0,0,255);stroke-width:1; stroke:rgb(0,0,0)"/> </svg> ' -- Don't forget this closing quote
In the result set, click in a cell that contains (IMAGE), click ..., and then choose View in Window.
