Sergey,
It's a known behaviour with SQL update. It gets the first reference as an 'alias'. ie:

update myTable set myField = thisform.myProperty

Would work using 'thisform' as an 'alias'. But this one doesn't :

update myTable set myField = thisform.myObj.myProperty

IOW you need alias.fieldname style.

In order to use Uppdate SQL in your sample above you'd need variables :

local lcName
lcName = This.parent.Text1.value
UPDATE mytable SET name1=lcName, .... where ...

PS: This would also work :
UPDATE mytable SET name1=eval('This.parent.Text1.value'), .... where ...
