Is COALESCE supported by QODBC?
When I try to select something that may contain NULL and would like to have an empty string instead of NULL I get an error.
If COALESCE is not supported then what can I use to return an empty strings instead of NULLs?
Thank you

Sorry COALESCE is not supported. But you can use IFNULL:
Select Name, {fn IFNULL(Fax, ' ')} as Fax from Employee where Fax is Null
to change a null value of a column to another string.
Select Name, {fn IFNULL(CustomFieldSpousesName, ' Not Married')} as Spouse from Employee
