Vantage implements cast functionality that allows data type conversions between VARCHAR and MBB types. To convert a VARCHAR type to an MBB type, the VARCHAR must use the following format:

(xmin, ymin, zmin, xmax, ymax, zmax)

where white space can appear anywhere.

Consider the following table definitions.

CREATE TABLE sample_MBBs (skey INTEGER, shape_mbb MBB);
CREATE TABLE sample_data (mbb_data VARCHAR(340));

This example performs MBR to VARCHAR data type conversion:

INSERT INTO sample_data
SELECT CAST(shape_mbb as VARCHAR(340))
FROM sample_MBBs;
