Apostrophes have to be escaped with another apostrophe. In Delphi, do
this:

sql.strings[2] := 'where upper(Last_Name)='
+ AnsiQuotedStr( uppercase(dbeditLastName.Text), '''' );

AnsiQuotedStr puts quote characters (specified in second arg) around
the string given in the first arg, and doubles any quote chars that
are in the string.

With single-byte character sets, you can also use

QuotedStr( s )

which is equivalent to

AnsiQuotedStr( s, '''' )

(Please note that '''' passes just *one* single-quote character to
the function.)
