Values in Db2 data types that are not supported by JSON, for examples the DATE or TIME data types are automatically converted into strings. If you're returning results with FOR JSON, and you're including data that's already in JSON format (in a column or as the result of an expression), wrap the JSON data with JSONQUERY without the path parameter. The value itself can represent a literal (true, false or null), a string, a number, a (nested) JSON object or a (nested) JSON array. As a result, FOR JSON doesn't escape special characters in the JSONQUERY return value. Use the latest LTS build from the website. The value is converted depending on the Db2 data type.
