In Sybase and in Python, if you enclose your text statements in double quotes, you must escape double quotes inside the text string and don't have to escape single quotes. Similarly, if you enclose using single quotes, you must escape the single quotes inside the text string and don't have to escape double quotes.
select "He's a ""big deal""" <-- will work fine
select 'He''s a "big deal"' <-- will work fine
select "He's a "big deal"" <-- will not work because the double quotes in the text are not escaped
select 'He's a "big deal"' <-- will not work because the single quote in the text is not escaped
I always use single quotes to enclose text and have a routine that escapes them for me
function escapeQuote theText
if "'" is in theText then
repeat with x = the number of chars in theText down to 1
if char x of theText = "'" then
put "'" before char x of theText
