What does 'error: invalid input syntax for type' mean in sql?

This error indicates that you're trying to insert or update a record with a value that's incompatible with the column's data type.


INSERT INTO users (age) VALUES ('thirty');


INSERT INTO users (age) VALUES (30); -- provided a numeric value instead of a string
Make sure to match the data types with the values you're inserting or updating.
