Criterion types.
In code this would be:Criterion crit=Restriction.eq(lngInsuranceId,5);
criteria.add(crit);
Following important methods of the Expression
class are shown in the table:
| Method |
Description |
| Restriction.allEq |
This is used to
apply an “equals”
constraint to each
property in the key
set of a Map |
| Restriction.between |
This is used to
apply a “between”
constraint to the
named property |
| Restriction.eq |
This is used to
apply an “equal”
constraint to the
named property |
| Restriction.ge |
This is used to
apply a “greater
than or equal”
constraint to the
named property |
| Restriction.gt |
This is used to
apply a “greater
than” constraint to
the named property |
| Restriction.idEq |
This is used to
apply an “equal”
constraint to the
identifier property |
| Restriction.ilike |
This is caseinsensitive
“like”,
similar to Postgres
ilike operator |
| Restriction.in |
This is used to apply
an “in” constraint to
the named property |
|
|
| Restriction.isNotNull |
This is used to apply
an “is not null”
constraint to the
named property |
| Restriction.isNull |
This is used to apply
an “is null” constraint
to the named
property |
| Restriction.le |
This is used to apply
a “less than or equal”
constraint to the
named property |
| Restriction.like |
This is used to apply a “like” constraint to
the named property |
| Restriction.lt |
This is used to apply a “less than”
constraint to the
named property |
| Restriction.ltProperty |
This is used to apply
a “less than”
constraint to two
properties |
| Restriction.ne |
This is used to apply
a “not equal”
constraint to the
named property |
| Restriction.neProperty |
This is used to apply
a “not equal”
constraint to two
properties |
| Restriction.not |
This returns the
negation of an
expression |
| Restriction.or |
This returns the
disjuction of two
expressions |
The Hibernate criteria query API provides two
query types that allow programmatic fetching
of persistent objects: query by criteria (QBC) |
