Paste Oracle or PostgreSQL CREATE TABLE statements into the input area.
Run the analysis and review tables, columns, types, constraints, defaults, and comments.
Check any warnings alongside the original DDL before using the extracted definition.
What DDL Analyzer does
It parses CREATE TABLE definitions and table or column comments. Results include data types, length, precision, scale, NULL rules, default values, and primary keys.
Useful for
Reviewing database definitions before migration
Summarizing tables for design documentation
Spotting column constraints and comments quickly
Supported SQL and limitations
Parsing targets common Oracle and PostgreSQL CREATE TABLE syntax. Input is limited to 512 KiB, 100 tables, 1,000 columns per table, and nesting depth 64. This is not a full SQL validator; unsupported statements such as ALTER TABLE and CREATE TABLE AS may be omitted or warned about.
Privacy
DDL analysis runs in your browser, and pasted definitions are not sent to an application server. Anonymous page-access analytics are described in the Privacy Policy.
