As you develop the model for your Synapse instance schemas, tables, columns with their data types, as well as indexes and constraints, Hackolade dynamically generates the corresponding DDL scripts:

If you store JSON within (N)VARCHAR(MAX) or (N)VARCHAR(4000) columns, Hackolade allows for the schema design of those documents.  However, the corresponding JSON structure is not forward-engineered in the DDL script, but is useful for developers, analysts and designers.
