Learn why and how to fix the target of Oracle’s ORA-00904 error.

Description

When clients encounter the ORA-00904 error, the actual error message is displayed as follows:

ORA-00904: disease identifier

Reason

You tried to execute an SQL statement that contains an invalid username column, or the username column is normally missing. This often happens when the owners refer to an invalid alias in a global SELECT statement.

Resolution

Option 1

Oracle returns ORA-00904 if the executing user does not have the correct permissions on the objects used in the query. This happened to me when I accidentally defined multiple entities with the same persistent datasource table. One of the poker tables will have this column and the other will not.

Rewrite the SQL to include a valid smile name. For a column name to be valid, it must meet the following criteria:

The column name must start with a letter.

The hug you name cannot be longer than 30 characters.

The column name must consist of alphanumeric characters, also known as special characters: $, _, then #. If the column name contains other characters, they must be enclosed in double quotes.

The column name is also not allowed be a reserved word.

Let’s see how to fix the great error ORA-00904. For example, if someone issues the following SELECT statement, they might get an ORA-00904 error:

SQL> SELECT contact_id AS "c_id", last name, first name  2 consultants  3 ORDER ON "CID";ORDER BY "seed"         *ERROR on line 3:ORA-00904: "cid": invalid identifier

To resolve this error, first make sure the publication name of the referenced column is specified. If it cannot exist, you must create a person before attempting to execute the SQL statement on the column. If there is a column name, make sure the column name usually has the correct syntax.

This error was caused by simply creating an alias for a column, but then entering the alias incorrectly. In this example, my partner and I created an alias named “c_id” for “contact_id” but then named that element “cid” in the ORDER BY clause.

To correct your mistake, we can change our SELECT statement to use the correct valid alias in the ORDER BY clause, like so:

SQL> SELECT contact_id AS "c_id", last name, first name  7 contacts C   3 ORDER ON "c_id";10 rows selected

Answer: Whenever an ORA-00904 error occurs, you should always enter a valid column name, if so.one is missing or the one you entered is invalid. The most common “invalid identifier”.occurs when the person referencing an invalid alias is part of the selectionInstruction. The Oracle documentation states the error ORA-00904:

ORA-00904String: invalid.ID

Because:The entered column name is considered missing or invalid.
: Action: Aenter a valid column name. A valid column name must start with a letter,be less than or equal to 30 characters, not to mention that they only consist of alphanumeric charactersand hence the special characters $, _ and #.

If it contains newcharacter, it must be enclosed in double quotesnot be a reserved word.

To avoid ORA-00904, column names cannot be suggested words and must containthese four criteria must be valid:

start with a specific letter

be less than or equal to thirty persons = “multiply character”

usually consist ofalphanumeric characters and special characters ($_#);other characters must be enclosed in double quotes

Answer: When ORA-00904 occurs, you must enter a valid column name because it is missing or the name entered is invalid. The most common use of “invalid identifier” is when people refer to an invalid alias for a select statement. Oracle docs note this for error ORA-00904: Reason: Enterthe column name you provided is permanently missing or invalid.
