Hi Aubrey,

I also have similare problems and wonder if you have got any further with yours?

I recently have 2 similar problems like yours. Both of them trigger the "Error 45: Not a character expression" error.

In the first one, I merged two class methods to one, the problem went away.
In the second one, I changed a SQL so as not to use a variable in the 'FROM' clause as below and the problem went away.

select TT.* from (AliasName) TT where TT.Id > 100   && this trigger the Error 45
select TT.* from MyTable TT where TT.Id > 100       && no more errors

I don't think I find the solution and hope you (or someone out there) can point me to the right direction.

Thanks.
