The Database Tour has a large set of functions for different types of database fields like text, numeric, graphic etc.
You can use several useful functions for selected fields of a table: trimming, changing case of symbols etc.
You can perform several arithmetic operations with a selected numeric field of the selected dataset: sum, average, min, max.
You can search and replace text in database tables or queries (including BLOB and CLOB fields) as long as in interface parts of the program.
Working with long text or graphic data is possible in the Blob Editor.
