[font="Arial"]I add the same problem with SQL Server :

"something"+char(9)+"something"

returns something something

"something"+char(9) + char(9)+char(9)+char(9)+char(9)+char(9)+"something"

returns something something

finally, I "cheated" with :

"something"+char(9)+char(160)+char(9)+char(160)+char(9)+char(160)+char(9)+char(160)"something"

returns something [8 spaces here] ...
