Update
schema.json
to correctly describe the 'alter column' operation.The alter column operation is used to perform different alter column operations according to which fields are present.
The rules are:
table
andcolumn
are always required.name
,type
,check
,unique
,references
,nullable
must be present.type
,check
,unique
,references
ornullable
is present, thenup
anddown
must also be present.name
is present then neitherup
ordown
is allowed.This PR updates
schema.json
to capture these dependencies.This change causes churn in the test code as some fields that previously
string
have become*string
.Fixes #222
