Toad for Oracle Base (64-bit) 188.8.131.520 : (idem in 16.2)
With the schema browser, I want to alter a table : (with 230 columns) :
clic on table, Alter => Toad killed !
(Loading constraint to GUI...150 of 230, out of system ressource)
With a table with less columns it’s OK.
So, you don't just have 230 columns, you have 230 constraints also?
I create a new table with 230 columns without constraint, on SYSTEM schema, it's the same, TOAD killed after Alter.
I can reproduce it if there are a lot of constraints (NOT NULL counts as a constraint).
I can load a table with 1000 columns without any problems if there are no constraints.
Thanks for reporting it. I'll investigate.
This will be fixed in the next beta.
