Although you can call the function directly, JSON_DECOMPRESS is often used with the DECOMPRESS USING phrase to uncompress table columns. In the following table, the JSON data in the json_col column is uncompressed using the JSON_DECOMPRESS function.

CREATE TABLE temp (
   id        INTEGER,
   json_col  JSON(1000) 
             CHARACTER SET LATIN 
             COMPRESS USING JSON_COMPRESS
             DECOMPRESS USING JSON_DECOMPRESS);
