In MySQL, obtaining a list of table names within a database is typically achieved using the SHOW TABLES command. However, this method is not suitable for populating another table with those names using a direct INSERT INTO query.
To achieve this goal, a standard SELECT statement can be utilized, but it requires accessing the appropriate table within the MySQL system database. That table is the information_schema.tables table, which houses information about all tables in the connected server.
To get the names of all tables in the MySQL server:
SELECT table_name FROM information_schema.tables;
To get the names of tables from a specific database:
SELECT table_name FROM information_schema.tables WHERE table_schema = 'your_database_name';
To insert the table names into another table:
INSERT INTO metadata(table_name) SELECT table_name FROM information_schema.tables WHERE table_schema = 'your_database_name';
Utilizing the information_schema.tables table enables the retrieval of table names using a regular SELECT statement, resolving the issue of directly inserting table names obtained from the SHOW TABLES command.
