周雁鸣 ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYTE0MDRkNGJk... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16419?atlOrigin=eyJpIjoiYTE0MD... ) HHH-16419 ( https://hibernate.atlassian.net/browse/HHH-16419?atlOrigin=eyJpIjoiYTE0MD... ) Regression on calling postgresql functions via CriteriaBuilder ( https://hibernate.atlassian.net/browse/HHH-16419?atlOrigin=eyJpIjoiYTE0MD... ) Issue Type: Bug Affects Versions: 6.1.7 Assignee: Unassigned Components: hibernate-core Created: 02/Apr/2023 22:57 PM Priority: Major Reporter: 周雁鸣 ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) public static <T> Predicate contains(Root<T> root, CriteriaBuilder cb, String propertyName, String item) { Assert.doesNotContain(item, "," , " 'item' should not contains comma" ); Dialect dialect = getDialect(cb); if (dialect instanceof MySQLDialect) { return cb.greaterThan(cb.function( "find_in_set" , Integer.class, cb.literal(item), root.get(propertyName)), 0); } if (dialect instanceof PostgreSQLDialect) { return cb.equal(cb.literal(item), cb.function( "any" , String.class, cb.function( "string_to_array" , String [].class, root.get(propertyName), cb.literal( "," )))); } return cb.like(cb.concat(cb.concat( "," , root.get(propertyName)), "," ), '%' + item + '%' ); } This method will generate sql for PostgresQL like: select count (t1_0.id) from test_entity t1_0 where 'name0' = any (string_to_array(t1_0. names , ',' )) It works fine with hibernate 5.x, but failed with 6.x, It comes from two issues. * cb.function("string_to_array", String[].class, ... ) will throw java.lang.IllegalArgumentException: Passed `invariantType` for function return cannot be null , because SqmCriteriaNodeBuilder::function doesn’t recognize array type String[].class , It may resolved by final BasicType<T> resultType; if (type.isArray()) { BasicType<?> componentType = getTypeConfiguration().getBasicTypeForJavaType(type.getComponentType()); resultType = new BasicArrayType(componentType, componentType.getJdbcType(), componentType.getJdbcJavaType()); } else { resultType = getTypeConfiguration().getBasicTypeForJavaType(type); } * cb.function("any", ... ) will throw org.hibernate.QueryException: Parameter 1 of function bool_or() has type BOOLEAN, but argument is of type java.lang.String , It seems conflict with built-in function from CommonFunctionFactory ( https://hibernate.atlassian.net/browse/HHH-16419#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16419#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
