What if, instead of a table’s data, you wanted to see the table’s metadata? That is, instead of querying all of the rows within a table where x or y are true, you wanted to see a list of all of the columns where z is true.
How would you do that?
It’s actually quite simple:
SELECT * FROM information_schema.columns WHERE table_name = 'target_table' AND table_schema = 'target_schema';
table_schema is required only if you have multiple schemas you’re choosing between. If all tables are in the
public schema or if there’s only a single table with the name, it can be excluded .
If you’re using the command line, it appears that
\d+ <target_table> would also work.
