Query failed: syntax error at or near "*"

I try to do this select from * "tablename"; and say:

Query failed: syntax error at or near ""
I also try to drop that table drop table if exist "tablename" and say:

Query failed: syntax error at or near “exist”

This error appears after include a new row in the table, however, I didn’t modify the table name.
What happen?

You’re using invalid SQL. Try select * from "tablename" and DROP TABLE IF EXISTS "tablename".
