Optimization Suggestion ----------------------- Key: CORE-5683 URL: http://tracker.firebirdsql.org/browse/CORE-5683 Project: Firebird Core Issue Type: Improvement Affects Versions: 3.0.2, 2.5.7 Reporter: Stefan Schmaltz
We have a Database with UNICODE_CI and all varchar field have an Index. So when executing SELECT ...WHERE field='value' ... ORDER BY field the result is fast but when executing SELECT ... WHERE UPPER(field)=UPPER('value') ... ORDER BY UPPER(field) the result is very slow. Suggestion: Case Insensitive Index should ignore UPPER (AND LOWER) because there is no difference -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tracker.firebirdsql.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
