We have made an update to ZIM Base so that UPDATE can SET a value without binding. For instance to increase or decrease a value in a column.
We had thought that this could be done by setting the update values to null and then using the "more" string to add whatever special SET values - but it turns out that SET cannot be used after WHERE... we did not know that. Wonder if it has always been that way or if this is something new in PHP. Whatever.
So now, the value can be escaped with a \ and this will pass the value through without binding.
