ORA-00922
ORA-00922: missing or invalid option is one of many Oracle errors, which does not point to a concrete and easily identifiable problem. The key to resolving this issue is to find the specific location of the error (which can be tedious) and correct its syntax. A small error such as a misplaced comma or missing quotation mark can throw this error. To make things easier, use a good integrated development environment software application to help identify syntactical errors that are hard to catch on your own.
The Problem
ORA-00922: missing or invalid option occurs if an invalid option is specified while defining a storage clause or column. Oracle provides the following information about this error:
Cause: The valid option in specifying a column is NOT NULL to specify that the column cannot contain any NULL values. Only constraints may follow the datatype. Specifying a maximum length on a DATE or LONG datatype also causes this error.
The Solution
Resolving ORA-00922: missing or invalid option can be tricky as the error does not appear due to one, universal cause. Oracle simply states that the syntax must be corrected. The user must remove the erroneous option or length specification from the column or storage specification.
In the following example, a table named employee is created:
CREATE table employee
(employee_id(5) NOT NULL, employee_name varchar2(30) employment_length varchar2 (40))
While this code seems correct at first glance, there is a missing comma after “employee_name varchar2(30),” throwing off the entire code and warranting ORA-00922 error message. The corrected code should read:
CREATE table employee
(employee_id(5) NOT NULL, employee_name varchar2(30), employment_length varchar2 (40))
ORA-00922: missing or invalid option is commonly seen during the installation process, specifically when creating new passwords. It installer may state that the user cannot be created along with the message: “missing or invalid option.” In such cases, the error is likely occurring because you are attempting to create a password that is complex. Changing the password to a less complex, weaker password will allow you to resolve the error and complete the installation successfully. Note that you can change the password to a stronger one after the installation is complete.
Moving Forward
If you continue to face problems with ORA-00920: missing or invalid option, you may consider contacting your database administrator for assistance if you yourself are not the DBA. Another option may be to contact an Oracle professional to resolve the issue. Remember to always check the consultant’s credentials and certification to ensure your Oracle needs are properly met.
ORA-00922
ORA-00922: неправильная опция
Причина:
Была указана неправильная опция в определении колонки или параметра памяти. Правильная опция при определении колонки как NOT NULL для указания, что колонка не содержит нулевых значений. Только ограничения могут следовать за типом данных. Указывая максимальную длину данных типа DATE или LONG вы будете часто вызывать эту ошибку.
Действие:
Проверьте ваш синтаксис и спеллинг. Удалите неправильную опцию или спецификацию длины из области определения колонки.

- Incorrect syntax in the SQL statement
- Missing or invalid options in the statement
- Misplacement of keywords in the statement
The error message usually appears as follows:
ORA-00922: missing or invalid option
To resolve this error, you need to identify the cause of the issue and correct it accordingly.
Step-by-Step Guide to Resolve ORA-00922 Error
Follow these steps to fix the ORA-00922 error:
Step 1: Review the SQL Statement
The first step is to carefully review the SQL statement that caused the error. Look for any syntax errors, missing options, or misplaced keywords. You can also use an SQL formatter to help you identify any syntax issues.
Step 2: Correct the SQL Statement
Once you have identified the issue, correct the SQL statement accordingly. Here are some common issues and their solutions:
Incorrect Syntax: Ensure that your SQL statement follows the correct syntax for the specific command you are using. Refer to the Oracle SQL documentation for the correct syntax.
Missing Options: If you have missed any required options in the SQL statement, add them accordingly. For example, if you are creating a table and have missed specifying the data type for a column, add the data type.
Misplaced Keywords: Ensure that all keywords are placed correctly in the SQL statement. For example, if you are using the CONSTRAINT keyword in a CREATE TABLE statement, make sure it is placed after the column definition.
Step 3: Test the Corrected SQL Statement
After correcting the SQL statement, test it by executing the statement in your Oracle environment. If the statement executes successfully, the ORA-00922 error has been resolved. If the error still persists, review the statement again and ensure that all issues have been addressed.
