Example 1: how to get all table names in sql query
BY LOVE SINGH
SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_CATALOG='YOUR_Database_name'
Example 2: sql all columns
-- MySQL
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS;
-- SQL Server (possible solution)
SELECT *
FROM SYS.COLUMNS;
-- Oracle
SELECT *
FROM ALL_TAB_COLS; -- (If you only want user-defined columns)
-- ALL_TAB_COLS : only user-defined columns
-- ALL_TAB_COLUMNS : both user-defined AND system columns
