Teradata Database 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;
