Field Details

COMPATIBLE_MODE

public static final String COMPATIBLE_MODE

We added a flag to enable a JPA compatible mode because we allow to make use of many vendor specific extensions which maybe aren't portable. By enabling the compatible mode functionality is restricted but more portable. By default the compatible mode is disabled because most JPA providers support the same extensions. Valid values for this property are true or false.

Since:

1.0.5

• Constant Field Values

RETURNING_CLAUSE_CASE_SENSITIVE

public static final String RETURNING_CLAUSE_CASE_SENSITIVE

Some databases require case sensitivity for attribute paths in the returning clause (unlike PostgreSQL which requires case insensitivity for column names in returning clause) By default the returning clause is case sensitive. Valid values for this property are true or false. The property can be changed for a criteria builder before generating the query.

Since:

1.1.0

See Also:

• Constant Field Values

SIZE_TO_COUNT_TRANSFORMATION

public static final String SIZE_TO_COUNT_TRANSFORMATION

If set to false, uses of SIZE will always be transformed to subqueries. By default the size to count transformation is enabled. Valid values for this property are true or false. Default is true The property can be changed for a criteria builder before generating the query.

Since:

1.1.0

See Also:

• Constant Field Values

IMPLICIT_GROUP_BY_FROM_SELECT

public static final String IMPLICIT_GROUP_BY_FROM_SELECT

If set to false, no implicit group by clauses will be generated from the SELECT part of the query. Valid values for this property are true or false. Default is true The property can be changed for a criteria builder before generating the query.

1.1.0

See Also:

• Constant Field Values

IMPLICIT_GROUP_BY_FROM_HAVING

public static final String IMPLICIT_GROUP_BY_FROM_HAVING

If set to false, no implicit group by clauses will be generated from the HAVING part of the query. Valid values for this property are true or false. Default is true The property can be changed for a criteria builder before generating the query.

Since:

1.1.0

See Also:

• Constant Field Values

IMPLICIT_GROUP_BY_FROM_ORDER_BY

VALUES_CLAUSE_FILTER_NULLS

public static final String VALUES_CLAUSE_FILTER_NULLS

If set to false, tuples of a VALUES clause with all null values won't be filtered out. Valid values for this property are true or false. Default is true The property can be changed for a criteria builder before using the VALUES clause.

Since:

1.2.0

See Also:

• Constant Field Values

PARAMETER_AS_LITERAL_RENDERING

public static final String PARAMETER_AS_LITERAL_RENDERING

If set to false, parameters are always rendered as such, otherwise the values might get inlined when no type can be inferred. Valid values for this property are true or false. Default is true The property can be changed for a criteria builder before constructing a query.

Since:

1.2.0

See Also:

• Constant Field Values

OPTIMIZED_KEYSET_PREDICATE_RENDERING

public static final String OPTIMIZED_KEYSET_PREDICATE_RENDERING

INLINE_ID_QUERY

public static final String INLINE_ID_QUERY

If set to true, the id query in a PaginatedCriteriaBuilder is inlined into the object query as subquery. Valid values for this property are true, false or auto. Default is auto which will make use of inlining if the JPA provider and DBMS dialect support it. The property can be changed for a criteria builder before generating the query.

INLINE_CTES

public static final String INLINE_CTES

If set to true, the CTE queries are inlined by default. Valid values for this property are true, false or auto. Default is true which will always inline non-recursive CTEs. The auto configuration will only make use of inlining if the JPA provider and DBMS dialect support/require it. The property can be changed for a criteria builder before constructing a query.

Since:

1.5.0
