I use MS Access (2003) database. Once I create a column I set NOT NULL using sql statement:
ALTER TABLE Table1
ALTER column myColumn INTEGER not null
Is there a way to change it back to allow null values? I already tried:
ALTER TABLE Table1
ALTER column myColumn INTEGER null
but nothing...
You cant specify null
in ALTER TABLE
(although not null
is allowed)
See the below documentation and also this discussion on this toppic
Syntax
ALTER TABLE table {ADD {COLUMN field type[(size)] [NOT NULL] [CONSTRAINT index] | ALTER COLUMN field type[(size)] | CONSTRAINT multifieldindex} | DROP {COLUMN field I CONSTRAINT indexname} }
