Example: Implicit Conversion of VARBYTE to BLOB - Teradata Vantage - Analytics Database

Consider the following table definitions:

CREATE TABLE small_images 
  (id INTEGER
  ,image1 VARBYTE(30000)
  ,image2 VARBYTE(30000));
   
CREATE TABLE large_images 
  (id INTEGER
  ,image BLOB);

Analytics Database performs a VARBYTE to BLOB implicit conversion for the following INSERT statement:

INSERT large_images
SELECT id, image1 || image2
FROM small_images;
