AccessSpecificCreator Methods

The AccessSpecificCreator type exposes the following members.

Methods
  NameDescription
Protected methodAddParameterToScopeTracker
Adds the parameter to scope tracker.
(Overrides DbSpecificCreatorBaseAddParameterToScopeTracker(DbParameter).)
Public methodAppendEscapeClauseForLikePredicate
Appends the character specified to the string builder specified together with ESCAPE to use it as an escape. If a database doesn't support the ESCAPE clause, implement this method and simply return null. By default this method appends ESCAPE parameter, where parameter is a string parameter with the character specified.
(Inherited from DbSpecificCreatorBase.)
Public methodAppendJoinSideToJoinFragments
Appends the elements as a join side to the fragments passed in in the default format: ElementName temporalPredicate alias tableHint. If an element is specified as empty/null, the element is skipped and no trailing space is emitted.
(Inherited from DbSpecificCreatorBase.)
Public methodAppendValidIdentifier
Routine which creates a valid identifier string for the plain identifier string passed in and appends the fragments to the queryfragments specified. For example, the identifier will be surrounded by "[]" on sqlserver. If the specified rawIdentifier needs wrapping with e.g. [], the [ and ] characters are added as separate fragments to toAppendTo so no string concatenation has to take place. Use this method over CreateValidAlias if possible.
(Overrides DbSpecificCreatorBaseAppendValidIdentifier(QueryFragments, String).)
Public methodClampNameToLengthLimit
Method which clamps the passed in string to F__hashcode of toClamp if the length of toClamp is too long and this creator's useRestrictedLengthOnAliasesOfFields is set to true in the ctor (which is the case in DB2 and Oracle)
(Inherited from DbSpecificCreatorBase.)
Protected methodConstructCallToAggregateWithFieldAsParameter
Constructs a call to the aggregate function specified with the field name specified as parameter.
(Overrides DbSpecificCreatorBaseConstructCallToAggregateWithFieldAsParameter(AggregateFunction, String).)
Public methodConvertComparisonOperator
Converts the passed in comparison operator to a string usable in a query.
(Inherited from DbSpecificCreatorBase.)
Public methodConvertExpressionOperator
Converts the passed in expression operator (exop) to a string usable in a query
(Overrides DbSpecificCreatorBaseConvertExpressionOperator(ExOp).)
Public methodConvertExpressionToQueryFragment
Converts the expression to a query fragment and adds the parameters created during this process to the passed in parametercollection
(Inherited from DbSpecificCreatorBase.)
Protected methodConvertFieldToRawName
Converts the name of the field to the plain base name to use further in the CreateFieldName routine. This routine makes sure expressions and function calls are taken into account. Used as the start call from CreateFieldName.
(Inherited from DbSpecificCreatorBase.)
Public methodConvertParameterOutputValueToRealValueT
Converts the parameter output value (contained in the parameter specified) to a real value. This is necessary for example if the value of the parameter is a value of a type native to an ADO.NET provider, like OracleDecimal.
(Inherited from DbSpecificCreatorBase.)
Public methodConvertSetOperator
Converts the passed in set operator to a string usable in a query
(Inherited from DbSpecificCreatorBase.)
Public methodConvertSortOperator
Converts the passed in sort operator to a string usable in a query
(Inherited from DbSpecificCreatorBase.)

(Overrides DbSpecificCreatorBaseCreateDynamicQueryEngine.)
Public methodCreateFieldName(IEntityFieldCore, IFieldPersistenceInfo, String, String, Boolean)

(Inherited from DbSpecificCreatorBase.)
Public methodCreateFieldName(IFieldPersistenceInfo, String, String, String, String)
Creates a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required. This field name is not padded with an alias if that alias should be created. Effectively, this is the same as CreateFieldName(field persistence info, fieldname, false);
(Inherited from DbSpecificCreatorBase.)
Public methodCreateFieldName(IFieldPersistenceInfo, String, String, Boolean, String, String)
Creats a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required.
(Inherited from DbSpecificCreatorBase.)
Public methodCreateFieldNameSimple(IFieldPersistenceInfo, String)
Creates a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required. This field name is not padded with an alias if that alias should be created. Effectively, this is the same as CreateFieldNameSimple(field persistence info, fieldname, false);. The fieldname is 'simple' in that it doesn't contain any catalog, schema or table references.
(Inherited from DbSpecificCreatorBase.)
Public methodCreateFieldNameSimple(IFieldPersistenceInfo, String, Boolean)
Creats a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required. The fieldname is 'simple' in that it doesn't contain any catalog, schema or table references.
(Inherited from DbSpecificCreatorBase.)
Public methodCreateHintStatement Obsolete.
Creates the hint statement for the hint passed in.
(Inherited from DbSpecificCreatorBase.)
Public methodCreateLikeParameter
Creates a valid Parameter for the pattern in a LIKE statement. This is a special case, because it shouldn't rely on the type of the field the LIKE statement is used with but should be the unicode varchar type.
(Overrides DbSpecificCreatorBaseCreateLikeParameter(String, String).)
Public methodCreateNewAliasScope
Creates a new alias scope and makes it active.
(Inherited from DbSpecificCreatorBase.)
Public methodCreateObjectName(IFieldPersistenceInfo)

(Inherited from DbSpecificCreatorBase.)
Public methodCreateObjectName(String, String, String)

(Inherited from DbSpecificCreatorBase.)
