RdbmsFunctionalityAspect Enumeration |
General list of definitions which a driver can list in its functionality aspect list, so LLBLGen Pro can
behave differently based on the database targeted. Only the functionality aspects relevant for LLBLGen Pro
are listed.
Namespace:
SD.LLBLGen.Pro.DBDriverCore
Assembly:
SD.LLBLGen.Pro.DBDriverCore (in SD.LLBLGen.Pro.DBDriverCore.dll) Version: 5.7.0.0 (5.7.0)

Public Enumeration RdbmsFunctionalityAspect
Members
| Member name | Value | Description |
---|
| AutoGenerateIdentityFields | 0 |
When a driver specifies this functionality aspect, LLBLGen Pro will assume the database system will autogenerate
Identity fields and will not allow specification of a value for an identity column for insert statements.
|
| UsesSequencesForIdentityFieldValues | 1 |
When a driver specifies this functionality aspect, LLBLGen Pro will assume that there are 0 or more sequences specified
in the schemas which can be used for value specification for Identity fields. Databases which use sequences are f.e. Oracle
and Postgresql.
|
| SupportsMultipleCentralUnitsPerProject | 2 |
When a driver specifies this functionality aspect, LLBLGen Pro will assume that multiple central units can be added to a project
and a single connection string can give access to all the catalogs at runtime. With oracle, this can be multiple schema's, with
DB2 and SqlServer, this can be multiple catalogs.
|
| CentralUnitIsCatalog | 3 |
When a driver specifies this functionality aspect, LLBLGen Pro will assume that the central unit of a database is a catalog,
like DB2 and SqlServer use. MySql will also have this option set.
|
| CentralUnitIsSchema | 4 |
When a driver specifies this functionality aspect, LLBLGen Pro will assume that the central unit of a database is a schema,
like Oracle.
|
| CentralUnitIsFile | 5 |
When a driver specifies this functionality aspect, LLBLGen Pro will assume that the central unit of a database is a file, like
Firebird, access
|
| SupportsMultipleSchemasPerCentralUnit | 6 |
When a driver supports multiple schemas per central unit, this is specified. Only specified if CentralUnitIsCatalog is set as well.
DB2 and SqlServer specific.
|
| SupportsForeignKeyConstraints | 7 |
If the database offers FK constraints so the system can utilize these to build relations. Every driver except MySql offers this.
|
| SupportsSchemaOnlyResultsetRetrieval | 8 |
If the database offers schema only resultset retrieval for stored procedures, this aspect should be added.
|
| SupportsNaturalCharacterSpecificTypes | 9 |
If the database offers specific natural character types, like NChar, this aspect should be added.
|
| OutputParametersFormStoredProcedureResultset | 10 |
If the database defines a stored procedure resultset through output parameters, this aspect should be added (e.g. Firebird does this).
|
| SupportsUpdateRules | 11 |
If the database supports UPDATE CASCADE rules on foreign key constraints, this aspect should be added.
|
| SupportsDeleteRules | 12 |
If the database supports DELETE CASCADE rules on foreign key constraints, this aspect should be added.
|
| SupportsDefaultSequences | 13 |
If the database supports sequence references as default values, this aspect should be added. It influences the designer to add
the sequence set to the table field as default sequence in model-first scenarios.
