Teradata Vantageā„¢ JSON Data Type

Teradata Database

Programming Reference

You can create an external stored procedure containing one or more parameters that are a JSON data type. You can use the JSON type to define IN, OUT, and INOUT parameters for procedures written in C, C++, and Java.

The JSON parameter type is allowed in routines that do not access SQL (NO SQL clause) as well as routines that contain the SQL access clause (CONTAINS/READS/MODIFIES SQL).

JSON FNC functions and Java classes and methods are provided to enable a UDF, UDM, or external stored procedure to access and set the value of a JSON parameter, or to get information about the JSON type parameter. For information about these functions and methods, see Teradata Vantageā„¢ SQL External Routine Programming , B035-1147 .
