ERROR: operator does not exist: character varying = integer

This error occurs when you are trying to compare or use the "=" operator between a column of data type "character varying" (text) and an integer value.
For example, if you have a table with a column "name" of data type "character varying" and you try to run a query like this:
SELECT * FROM table_name WHERE name = 123;
You will get the "operator does not exist: character varying = integer" error because you are trying to compare a text value with an integer value.
To fix this error, you need to make sure that you are comparing values of the same data type. If you want to compare the "name" column with an integer value, you can convert the "name" column to an integer using the CAST function:
SELECT * FROM table_name WHERE CAST(name AS INTEGER) = 123;
This will convert the "name" column to an integer before comparing it with the value 123.
