a valid SQL statement. This error can occur if the Procedural Option is not installed and a SQL statement is issued that requires this option (for example, https://docs.oracle.com/cd/B10501_01/server.920/a96525/e900.htm a CREATE PROCEDURE statement). You can determine if the Procedural Option is installed by starting SQL*Plus. If the PL/SQL banner is not displayed, then the option is not installed. Action: Correct the syntax or install the Procedural Option. ORA-00901 invalid CREATE command Cause: The CREATE command was not followed by a valid CREATE option. Action: Correct the syntax. ORA-00902 invalid invalid identifier datatype Cause: The datatype entered in the CREATE or ALTER TABLE statement is not valid. Action: Correct the syntax.

The name must be less than or equal to 30 characters and cannot be a reserved word. ORA-00904 string: invalid identifier Cause: The column name entered is either missing or invalid. Action: Enter a valid column name. A valid column name must begin with a letter, be less than or equal to 30 characters, and consist of only alphanumeric characters and the special characters $, _, and #. If it contains other characters, then it must be enclosed in double quotation marks. It may not be a reserved word. ORA-00905 missing keyword Cause: A required keyword is missing. Action: Correct the syntax. ORA-00906 missing left parenthesis Cause: A required left parenthesis has been omitted. Certain commands, such as CREATE TABLE, CREATE CLUSTER, and INSERT, require a list of items enclosed in parentheses. Parentheses also are required around subqueries in WHERE clauses and in UPDATE table SET column = (SELECT...) statements. Action: Correct the
