resolve this Oracle error are: Option #1 Rewrite your SQL to include a valid column name. To be a valid column name the following criteria must be met: The column name must begin with a letter. The column name can not be longer than 30 characters. The column name must be made up of alphanumeric characters or the following special characters: $, _, and #. If the column name uses any other characters, it must be enclosed in double quotation marks. The column name can not be a reserved word. Let's look at an example of how to resolve an ORA-00904 error.

In this example, we created the alias called "c_id" for the contact_id, but then called it as "cid" in the ORDER BY clause. To resolve this error, we can modify our SELECT statement to use the correct alias name in the ORDER BY clause as follows:

Some time it come if you use names, which happened to be reserved word in Oracle database. Now how do you resolve it? We will learn in this article, by following series of examples which first reproduce this error and later suggest how to fix it.
