- We are running DOS INFORMIX-4GL V 1.10.06E on a 286 Librex notebook
- running MS-DOS 5.0. We use the protected mode engine, and protected mode
- applications.
-
- Much of our code uses temp tables ; Often we execute statements such as
- the following :
-
- create temp table foo (s serial, x int, str char(20))
- .
- .
- declare c_mumble cursor for
- select int_val, str_val from another_tab
-
- foreach c_mumble into prg_var_int, prg_var_str
- insert into foo values (0, prg_var_int, prg_var_str)
- end foreach
- .
- .
- .
- .
- drop table foo
-
-
- This code works fine, if we only execute the sequence once per program
- run. However, when we attempt to create the temp table again, using the same
- sequence of code we get this error on the first insert attempt:
-
- Program stopped at [line of insert command]
- SQL statement error number -242.
- ISAM error number -9.
- Could not open database table (foo)
-
- We cannot understand why it cannot open the table, since the program just
- created it a few lines before. Obviously, it has something to do with
- dropping then creating it again, but we can figure out why. The code works
- perfectly on INFORMIX-4GL V 4.00 running on our AT&T 3B2/600 under
- AT&T UNIX SYS V R3.2.3.
-
- We attempted to remedy the problem by using a permenant table instead of
- a temp table. This executes better (i.e. we can drop and re-create more than
- once), but after about 4 drops and recreates it complete corrupts the database,
- so that it must be deleted and re-created.
-
- Has anyone had any problems of this nature with the PC version?
-
- Any help will be appreciated.
