This release of Rel<\/em>, an implementation of Date & Darwen’s Tutorial D<\/strong> database language, improves the user interface and fixes some bugs.<\/p>\n

The following enhancements have been made:<\/p>\n

– Rel<\/em> DBMS: Now provides -q command-line option to disable startup\/shutdown information messages. This is intended to make it easier to implement standalone scripts that produce console output for later redirection.<\/p>\n

– Rel<\/em> UI: Tabular displays of views, relvars, or expression evaluation results (in Rev visual query editor) now provide mechanism to search and sort the results.<\/p>\n

– Rev visual query editor: Advanced search available in Restrict (WHERE) operator.<\/p>\n

– Rev visual query editor: A Comment node has been provided, to add commentary to a visual query.<\/p>\n

– Rel<\/em> DBMS: new built-in operator SEARCH(t TUPLE{*}, regex CHAR) RETURNS BOOLEAN, which returns true if any CAST_AS_CHAR(a), where a is an attribute of t, matches regex. This permits general text search of tuples, e.g., S WHERE SEARCH(TUP {*}, “.*3.*”) returns any tuple in S with a ‘3’ in some attribute value.<\/p>\n

The following bugs have been fixed:<\/p>\n

– Rel<\/em> UI: In the command-line interface, attempting to execute a statement like WRITELN “blah\/\/”; — or other statement with a string with an embedded comment character sequence — caused syntax error, because \/\/ was treated as an expression ending in a comment rather than a statement. Fixed.<\/p>\n
