Error In Oracle List

Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although you cannot anticipate all possible errors, you can plan to handle certain kinds oracle error codes table of errors meaningful to your PL/SQL program. With many programming languages, unless you disable

the operating system. With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence of errors. This chapter discusses the following topics: Overview https://docs.oracle.com/cd/B28359_01/nav/lookup.htm?id=ERRMG of PL/SQL Error Handling Advantages of PL/SQL Exceptions Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How PL/SQL Exceptions Propagate Reraising a PL/SQL Exception Handling Raised PL/SQL Exceptions Tips for Handling PL/SQL Errors Overview of PL/SQL Error Handling In PL/SQL, a warning or error condition is called an exception. Exceptions can be internally defined (by the run-time system) or user defined. https://docs.oracle.com/cd/B10500_01/appdev.920/a96624/07_errs.htm Examples of internally defined exceptions include division by zero and out of memory. Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. Unlike internal exceptions, user-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. To handle raised exceptions, you write separate routines called exception handlers. After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment. In the example below, you calculate and store a price-to-earnings ratio for a company with ticker symbol XYZ. If the company has zero earnings, the predefined exception ZERO_DIVIDE is raised. This
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, a CREATE PROCEDURE https://docs.oracle.com/cd/B10501_01/server.920/a96525/e900.htm 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 http://www.ora-code.com/ 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 datatype Cause: The datatype entered in oracle error the CREATE or ALTER TABLE statement is not valid. Action: Correct the syntax. ORA-00903 invalid table name Cause: A table or cluster name is invalid or does not exist. This message is also issued if an invalid cluster name or no cluster name is specified in an ALTER CLUSTER or DROP CLUSTER statement. Action: Check spelling. A valid table name or cluster name must oracle error codes begin with a letter and may contain only alphanumeric characters and the special characters $, _, and #. 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 syntax, inserting a left parenthesis where required, and retry the statement. ORA-00907 missing right parenthesis Cause: A left p
