Postgresql Exception Handling Example

specifies the error severity. Allowed levels are DEBUG, LOG, INFO, NOTICE, WARNING, and EXCEPTION, with EXCEPTION being the default. EXCEPTION raises an error (which normally aborts the current transaction); the other levels only generate messages of different priority levels. Whether messages of a particular priority are reported to the client, written to the server log, or both is controlled by the log_min_messages and client_min_messages configuration variables. See Chapter 18 for more syntax error at or near "raise" information. After level if any, you can write a format (which must be a simple string literal, not an expression). The format string specifies the error message text to be reported. The format string can be followed by optional argument expressions to be inserted into the message. Inside the format string, % is replaced by the string representation of the next optional argument's value. Write %% to emit a literal %. In this example, the value of v_job_id will replace the % in the string: RAISE NOTICE 'Calling cs_create_job(%)', v_job_id; You can attach additional information to the error report by writing USING followed by option = expression items. The allowed option keywords are MESSAGE, DETAIL, HINT, and ERRCODE, while each expression can be any string-valued expression. MESSAGE sets the error message text (this option can't be used in the form of RAISE that includes a format string before USING). DETAIL supplies an error detail message, while HINT supplies a hint message. ERRCODE specifies the error code (SQLSTATE) to report, either by condition name as shown in Appendix A, or directly as a five-character SQLSTATE code. This example will abort the transaction with the given error message and hint: RAISE EXCEPTION 'Nonexistent ID --> %', user_id USING HINT = 'Please ch

I have almost one validation for each field of row. I want trigger to check all validations while insertion is being done and, raise error log afterwards once for all. Should I use raise exception on raise notice ? For example: Insert into first (first_column, noces,dob) values ('4545','75','545') I am checking noces is less than first_column, for the same row i want to check if dob > 80 and if first_column is integer and raise error for all validations.

If noces and first_column are character columns, < will not do what you expect. Never, ever store numbers in character columns! –a_horse_with_no_name Sep 21 '12 at 11:33 add a comment| 2 Answers 2 active oldest votes up vote 10 down vote accepted The quoting is wrong.

we will show you how to report messages and raise errors using RAISE statement. In addition, we will introduce you to the ASSERT statement for inserting debugging checks into PL/pgSQL block.PL/pgSQL reporting messagesTo raise a message, you use the RAISE statement as follows:1RAISE level format;Let's examine the components of the RAISE statement in more detail.Followed the RAISE statement is the level option that specifies the error severity. There are following levels in PostgreSQL:DEBUGLOGNOTICEINFOWARNINGEXCEPTIONIf you don't specify the level, by default, the RAISE statement will use EXCEPTION level that raises an error and stops the current transaction. We will discuss about the RAISE EXCEPTION later in the next section.The format is a string that specifies the message. The format uses percentage ( %) placeholders that will be substituted by the next arguments. The number of placeholders must match the number of arguments, otherwise PostgreSQL will report the following error message:1[Err] ERROR:too many parameters specified for RAISEThe following example illustrates the RAISE statement that reports different messages at the current time.12345678DO $$ BEGIN RAISE INFO 'information message %', now() ;RAISE LOG 'log message %', now();RAISE DEBUG 'debug message %', now();RAISE WARNING 'warning message %', now();RAISE NOTICE 'notice message %', now();END $$;123INFO:information message 2015-09-10 21:17:39.398+07WARNING:warning message 2015-09-10 21:17:39.398+07NOTICE:notice message 2015-09-10 21:17:39.398+07Notice that not all messages are reported back to client, only INFO, WARNING, and NOTICE level messages are reported to client. This is controlled by the client_min_messages and log_min_messages configuration parameters.PL/pgSQL raising errorsTo raise errors, you use the EXCEPTION level after the RAISE statement. Note that RAISE statement uses EXCEPTION level by default.Besides raising an error, you can add more detailed information using the following clause with the RAISE statement:1USING option = expressionThe option can be:MESSAGE: to set error message textHINT: to provide the hint message so that the root cause of the error is easier to be discovered.DETAIL:  to give detailed information about the error.ERRCODE: to identify the error code, which can be either by condition name or directly five-character SQLSTATE code. Please refer to the table of error codes and condition names.The expression is a string-valued expression.The following example raises a duplicate email error message:12345678910DO $$ DECLARE email varchar(255) := 'info
