Main tips on Dialect 1 to Dialect 3:
- Check your queries: avoid ambiguities in joined selects.All fields
must have a table alias, as in this example:
SELECT C.Name, S.Name
from Customer C inner join
Store S on C.Id_Store = S.Id_Store
- Check if the name of your fields (or column names in queries)
conflict with the reserved words of FB1.5.
- MUCH care with numeric(x,y) fields. Check on IB6 pdfs and in
Release notes what are used to store these numbers. There are
a calculation on CFLP portuguese list because just this. If the
precision is 10 ou more, use a DOUBLE PRECISION floating point field
(or cast the operanads to it and scale back) if your tests indicate
overflows
in calculations. On IB5.6 DOUBLE PRECISION is the storage datatype
of that column with precision 10 or above.
Hope this helps.
