Properties
  NameDescription
Public propertyActiveRecoveryStrategy
Gets or sets the active recovery strategy to use with supported actions on this DataAccessAdapter. If null (default), no recovery strategy is used and all exceptions are fatal.
Public propertyCatalogNameOverwrites
The from-to name value pairs and setting for the overwriting of catalog names.
Public propertyCatalogNameToUse
The name to use if catalogNameUsageSetting is set to ForceName. Ignored otherwise.
Public propertyCatalogNameUsageSetting
Configurates this data access adapter object how to threat catalog names in persistence information.
Public propertyCommandTimeOut
Gets / sets the timeout value to use with the command object(s) created by the adapter. Default is 30 seconds Set this prior to calling a method which executes database logic.
Public propertyConnectionString
Gets / sets the connection string to use for the connection with the database.
Public propertyFunctionMappings
Gets the function mappings for the DQE related to this DataAccessAdapter. These function mappings are static and therefore not changeable.
Public propertyInSystemTransaction
Gets a value indicating whether a System.Transactions transaction is going on. If not, false is returned.
Public propertyIsTransactionInProgress
Gets IsTransactionInProgress. True when there is a transaction in progress.
Public propertyKeepConnectionOpen
Gets / sets KeepConnectionOpen, a flag used to keep open connections after a database action has finished.
Public propertyKeepTrackOfTransactionParticipants
The flag (default true) is used to signal the adapter that entities participating in a transaction controlled by this adapter are tracked during the transaction and which values are rolled back after a rollback of the transaction itself. Only set this flag to false if the entities participating in a transaction are not kept in memory during or after the transaction's life time.
Public propertyParameterisedPrefetchPathThreshold
Gets or sets the parameterised prefetch path threshold. This threshold is used to determine when the prefetch path logic should switch to a subquery or when it should use a WHERE field IN (value1, value2, ... valueN) construct, based on the # of elements in the parent collection. If that # of elements exceeds this threshold, a subquery is constructed, otherwise field IN (value1, value2, ...) construct is used. The default value is 50. On average, this is faster than using a subquery which returns 50 elements. Use this to tune prefetch path fetch logic for your particular needs.

This threshold is also used to determine if paging is possible. A page size bigger than this threshold will disable the paging functionality when using paging + prefetch paths.
Protected propertyPhysicalTransaction
The physical transaction object used over the current ActiveConnection.
Public propertySchemaNameOverwrites
The from-to name value pairs and setting for the overwriting of schema names.
Public propertyTransactionIsolationLevel
Gets / sets the isolation level a transaction should use. Setting this during a transaction in progress has no effect on the current running transaction.
Public propertyTransactionName
Gets the name of the transaction. Setting this during a transaction in progress has no effect on the current running transaction.

Creates a savepoint with the name savePointName in the current transaction. You can roll back to this savepoint using Rollback(String).
Protected methodSetPerInstanceCompatibilityLevel
Sets the per instance compatibility level on the dqe instance specified.
Public methodStartTransaction
Starts a new transaction. All database activity after this call will be ran in this transaction and all objects will participate in this transaction until its committed or rolled back. If there is a transaction in progress, an exception is thrown. Will create and open a new connection if a transaction is not open and/or available.
Public methodStartTransactionAsync(IsolationLevel, String)
Async variant of StartTransaction(IsolationLevel, String). Starts a new transaction.

Returns a string that represents the current object.
(Inherited from Object.)
Public methodUpdateEntitiesDirectly
Updates all entities of the same type or subtype of the entity entityWithNewValues directly in the persistent storage if they match the filter supplied in filterBucket. Only the fields changed in entityWithNewValues are updated for these fields. Entities of a subtype of the type of entityWithNewValues which are affected by the filterBucket's filter will thus also be updated.
Public methodUpdateEntitiesDirectlyAsync(IEntity2, IRelationPredicateBucket)
Async variant of UpdateEntitiesDirectly(IEntity2, IRelationPredicateBucket). Updates all entities of the same type or subtype of the entity entityWithNewValues directly in the persistent storage if they match the filter supplied in filterBucket. Only the fields changed in entityWithNewValues are updated for these fields. Entities of a subtype of the type of entityWithNewValues which are affected by the filterBucket's filter will thus also be updated.
Public methodUpdateEntitiesDirectlyAsync(IEntity2, IRelationPredicateBucket, CancellationToken)
Async variant of UpdateEntitiesDirectly(IEntity2, IRelationPredicateBucket). Updates all entities of the same type or subtype of the entity entityWithNewValues directly in the persistent storage if they match the filter supplied in filterBucket. Only the fields changed in entityWithNewValues are updated for these fields. Entities of a subtype of the type of entityWithNewValues which are affected by the filterBucket's filter will thus also be updated.
Public methodWireTransaction
Wires an active transaction to the command object of the passed in query. If no transaction is in progress, nothing is wired.
