You can't have two statements per query. A query encapsulates one and only one statement. A "usual" TIBOQuery would be a SELECT statement returning a dataset consisting of a number of columns X a number of rows. Any row that the user edits would be updated by a statement automatically generated by IBO. Likewise, any inserted row would be set up for you by IBO; and deletions too.

However, if you need _custom_ SQL for your updates, inserts and/or deletes, you can plug special statements into the respective UpdateSQL properties. Look at InsertSQL, EditSQL and DeleteSQL. These properties need valid __executable__ SQL statements (i.e. not SELECT statements) and the replace the respective automatic statements that IBO creates when you call Insert, Edit or Delete.

This statement:
update salenum
set customernum = 1 + (select customernum
from salenum);

is not valid SQL. A sub-select is only permitted to return a single row. The statement in that subselect would return a row for each row in salenum.

select customernum
from salenum

I have no idea why you need this statement. Could you talk more about what you want to achieve?
