database_constraint/4

Availability::- use_module(library(cql/cql)).

[nondet,multifile]database_constraint(?Schema:atom, ?EntityName:atom, ?ConstraintName:atom, ?Constraint)

Constraint is one of:

primary_key(ColumnNames:list)
foreign_key(ForeignTableName:atom, ForeignColumnNames:list, ColumnNames:list)
unique(ColumnNames:list)
check(CheckClause)

In theory this can be autoconfigured too, but I have not written the code for it yet
