Generating Relational SQL Schemas from JSON Datasets

Learn how to inspect JSON datasets and generate PostgreSQL, MySQL, and SQLite CREATE TABLE schemas and INSERT migration statements.

Migrating document data into relational SQL databases requires determining proper column types (VARCHAR, INTEGER, TIMESTAMP, BOOLEAN, JSONB) and constructing safe DDL schemas and INSERT statements.

Automatic SQL Column Type Mapping

By scanning sample JSON objects, the inference engine maps whole numbers to INT, decimals to FLOAT, booleans to BOOLEAN, and nested structures to JSONB.
