Postgresql Sqlexception Error Codes
Contents |
8.3 / 8.4 / 9.0 PostgreSQL 9.4.9 Documentation Prev Up Next Appendix A. PostgreSQL Error Codes All messages emitted by the PostgreSQL server are assigned five-character error codes that follow the SQL standard's conventions for "SQLSTATE" postgres sqlstate codes. Applications that need to know which error condition has occurred should usually test the postgresql exception handling error code, rather than looking at the textual error message. The error codes are less likely to change across PostgreSQL releases, and also postgresql exception handling example are not subject to change due to localization of error messages. Note that some, but not all, of the error codes produced by PostgreSQL are defined by the SQL standard; some additional error codes for conditions not defined
Postgresql Error Codes
by the standard have been invented or borrowed from other databases. According to the standard, the first two characters of an error code denote a class of errors, while the last three characters indicate a specific condition within that class. Thus, an application that does not recognize the specific error code might still be able to infer what to do from the error class. Table A-1 lists all the error codes defined in PostgreSQL 9.4.9. (Some are postgres exception when others not actually used at present, but are defined by the SQL standard.) The error classes are also shown. For each error class there is a "standard" error code having the last three characters 000. This code is used only for error conditions that fall within the class but do not have any more-specific code assigned. The symbol shown in the column "Condition Name" is the condition name to use in PL/pgSQL. Condition names can be written in either upper or lower case. (Note that PL/pgSQL does not recognize warning, as opposed to error, condition names; those are classes 00, 01, and 02.) For some types of errors, the server reports the name of a database object (a table, table column, data type, or constraint) associated with the error; for example, the name of the unique constraint that caused a unique_violation error. Such names are supplied in separate fields of the error report message so that applications need not try to extract them from the possibly-localized human-readable text of the message. As of PostgreSQL 9.3, complete coverage for this feature exists only for errors in SQLSTATE class 23 (integrity constraint violation), but this is likely to be expanded in future. Table A-1.

Join them; it only takes a minute: error codes Sign up Postgres Exceptions and java up vote 0 down vote favorite I am using the “postgresql-9.3-1102.jdbc3.jar” in order to connect to the database. When I have one exception e.g. one null value, I can use several ways in order to catch the exception. e.g. try { ............} catch (PSQLException seRs) { ......... } Or try {.......} catch (SQLException se) {.......} Or try postgresql exception handling { .......} catch (Exception se) { ........ } My Goal is to catch the specific SQLState in the cases that I am interesting. For example I want to catch the invalid NULL value of one field, the Postgress returns the value “23502” SQLState but in any of the prior “catches” I can’t do it because the Error code is inherited I can’t check it. In the previous “catches” I can have the “.getmessage” but this is not helping me i want to check the SqlState Thanks for any ideas. java postgresql exception exception-handling share|improve this question asked Oct 15 '14 at 13:18 Elias Elias 124139 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted Catch SQLExceptoin then use SQLException.getSQLState() and compare it to see if it's what you want. catch (SQLException ex) { final String ss = ex.getSQLState(); //... blah blah ... } See PostgreSQL error codes for SQLState details. (While most of the state categories and codes are standard across DBs not all DBs implement them the same way and throw them at the same times, and
| Threaded Open this post in threaded view ♦ ♦ | Report Content as Inappropriate ♦ ♦ SQLException.getErrorCode ? The method SQLException.getErrorCode of the jdbc driver systematically returns 0, From what I have found on the web, the server doesn't have good support for error codes,and it is the reason the jdbc driver doesn't return error codes. The doc here talks about error codes : http://www.postgresql.org/docs/8.4/interactive/errcodes-appendix.htmlWhere are error codes support on the roadmap ? I would like to detect things like 'table does not exist' , constraint does not exist, etc.. from the SQLException Is there a workaround ? Thanks And thanks for the quick replies to my previous questions ! ;-) Kris Jurka Reply | Threaded Open this post in threaded view ♦ ♦ | Report Content as Inappropriate ♦ ♦ Re: SQLException.getErrorCode ?

As you can see the error conditions listed in the appendix are not all numeric so they cannot be returned via getErrorCode.

Why anyone would want to use error code instead of SQLSTATE is beyond me, but since they're out there, perhaps we should implement getErrorCode to interpret SQLSTATE as a base 36 number, and return that number? It might take less time than fielding the next complaint. ;-) If that sounds good, I could whip together a patch for it. The biggest down side is that we'd have to document it.... -Kevin -- Sent via pgsql-jdbc mailing list ([hidden email]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-jdbc Kris Jurka Reply | Threaded Open this post in threaded view ♦ ♦ | Report Content as Inappropriate ♦ ♦ Re: SQLException.getErrorCode ?
