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

   (xmin, ymin, xmax, ymax)

where white space can appear anywhere.

Consider the following table definitions.

   CREATE TABLE sample_MBRs (skey INTEGER, shape_mbr MBR);
   CREATE TABLE sample_data (mbr_data VARCHAR(256));

This example performs MBR to VARCHAR data type conversion:

   INSERT INTO sample_data
   SELECT CAST(shape_mbr as VARCHAR(256))
   FROM sample_MBRs;
