That is not possible. Each table (potentially) has a different structure, and so table names cannot be variables in a query - they must be specified when the SQL is parsed. But you could do this with an extension such as https://www.sqlite.org/src/artifact/f971962e92ebb8b0 that implements an SQL function that submits new SQL text to the SQLite parser. For example: SELECT name, eval(printf('SELECT count(*) FROM "%w"',name)) FROM sqlite_master WHERE type='table' AND coalesce(rootpage,0)>0; -- D.
