|sFilter||(String) Text string in the syntax of the SQL language statement WHERE that defines the condition for searching|
If the search is successful, the method returns an index of the found record and the pointer (of the current position) is set to this record, otherwise it returns the value -1 and the current position remains unchanged.
This method is not functional if the "Technology" configurator is set to Access through ODBC.
//Searching for the value John Saruman in the column of the text type named "Customer"
n = oDb.FindPrev("Customer = 'John Saruman'");
//Searching for the numeric item
n = oDb.FindPrev("Price > 10000");
//Searching for the time item. The time is set: - #month day year hour:minute:second#
n = oDb.FindPrev("Time > #10 24 2020 12:10:37#");
