Debug/logging: $wgShowSQLErrors
Whether to show SQL errors on "we're sorry, but there has been a database error" pages.
Wprowadzono w wersji:1.4.0 (r7376)

When set to false (default) any database error message will also say "(SQL query hidden)" rather than showing the SQL which caused the error. You will then only see "Wystąpił błąd podczas wykonywania zapytania do bazy danych. Może to wskazywać na błąd w oprogramowaniu.". Set $wgShowSQLErrors to true to see the actual query, which caused the error.

In MediaWiki 1.32, this setting got deprecated and is nonfunctional since then. Use Podręcznik:$wgShowExceptionDetails and Podręcznik:$wgShowHostnames instead!

Szczegóły

Clearly showing the SQL will aid in debugging in the event of a database error, however...

  • Showing SQL to all users, will give crackers some clues about the database structure of your website, and might help them find security weaknesses.
  • SQL database errors are not supposed to occur during any normal MediaWiki operation, and so with luck you will never need to improve the error information
  • If you receive the error internal_api_error_DBQueryError from the API, enabling this setting will display a more descriptive error message in the info field than the default Database query error.

If you do see an error including "(SQL query hidden)", it can be useful to set this to $wgShowSQLErrors = true; temporarily.

This variable replaces $wgIgnoreSQLErrors , which has been removed.
