Depending on how often the line is evaluated you might need more than one pair of backslashes, because every time the line is interpreted one of these pairs is "interpreted away". Try "\\'" (or maybe "\\\\'", etc.).

I hope this helps.

I'm not sure that it works :-)

Code:
ssh A 'ssh B awk 'BEGIN{printf "select * from testing where name =%ctest%c\n",39,39;}' '

Thanks All ! ! !
