How to View Schema in PostgreSQL

What is the quickest way to view a table schema in MySQL?

Run DESCRIBE table_name; to list each column, its data type, nullability, key status, default value, and extra attributes. It is the fastest, most widely-supported command for a high-level overview.

How do I see the full CREATE statement?

Execute SHOW CREATE TABLE table_name; to return the exact DDL used to build the table, including primary keys, foreign keys, indexes, and table options.This is essential when you need to recreate or version-control structures.

Can I inspect all tables at once?

Loop through information_schema.tables or use a GUI to script multiple SHOW CREATE TABLE statements.For a quick list, run SHOW TABLES; and iterate.

How do I query information_schema for column details?

Filter information_schema.columns by table_schema and table_name to get column names, data types, defaults, and comments programmatically, which is helpful for automated documentation.

Best practices when inspecting MySQL schemas

Always qualify tables with the database name in multi-schema environments, check for generated columns, and export DDL to version control.Use SHOW CREATE TABLE when cloning structures across environments.

Common errors to avoid

DESCRIBE omits indexes and constraints—use SHOW CREATE TABLE instead. When reading information_schema, forgeting the table_schema filter can mix results from other databases.
