# title:        ISQL extract command lose COMPUTED BY field types
# decription:   
#                  Test creates table with fields of (almost) all possible datatypes.
#                  Then we apply "ALTER TABLE ALTER FIELD ..., ALTER FIELD ..." so that every field is changed,
#                  either by updating its computed-by value or type (for text fields - also add/remove charset).
#                  Expression for ALTER TABLE - see literal "alter_table_ddl", encoded in UTF8.
#                  NB: changing character set should NOT be reflected on SQLDA output (at least for current FB builds).
#                  Confirmed bug on  WI-V3.0.0.32134 (RC1), fixed on: WI-V3.0.0.32311.
#                  :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#                  ::: NB ::: 
#                  It is possible that this test need to be adjusted soon for FB 3.0, because current SQLDA
#                  output is not affected by changing of field character set (adding or removing or updating).
