Namespace: SD.LLBLGen.Pro.DQE.DB2
The DB2SpecificCreator type exposes the following members.
Name | Description | |
---|---|---|
DB2SpecificCreator |
CTor
|
Name | Description | |
---|---|---|
AliasScopes |
Gets the alias scopes.
(Inherited from DbSpecificCreatorBase.) | |
CreatingSubQuery |
Gets a value indicating whether the creator initiated a subquery creation. The DQE can then decide to limit the SQL emitting as some databases
limit features for subqueries.
(Inherited from DbSpecificCreatorBase.) | |
FactoryToUse |
Gets the DbProviderFactory instance to use.
(Overrides DbSpecificCreatorBaseFactoryToUse.) | |
ParameterPrefix |
Gets the parameter prefix, if required. If no parameter prefix is required, this property will return the empty string (by default it returns the empty string).
(Overrides DbSpecificCreatorBaseParameterPrefix.) | |
PerCallCatalogNameOverwrites |
Gets / sets perCallCatalogNameOverwrites name pairs
(Inherited from DbSpecificCreatorBase.) | |
PerCallSchemaNameOverwrites |
Gets / sets perCallSchemaNameOverwrites name pairs
(Inherited from DbSpecificCreatorBase.) | |
SetTimeoutOnCommandCreate |
Gets a value indicating whether the timeout has to be set on command create.
(Inherited from DbSpecificCreatorBase.) |
Name | Description | |
---|---|---|
AddParameterToScopeTracker |
Adds the parameter to scope tracker.
(Inherited from DbSpecificCreatorBase.) | |
AppendValidIdentifier |
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).) | |
ClampNameToLengthLimit |
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.) | |
ConstructCallToAggregateWithFieldAsParameter |
Constructs a call to the aggregate function specified with the field name specified as parameter.
(Overrides DbSpecificCreatorBaseConstructCallToAggregateWithFieldAsParameter(AggregateFunction, String).) | |

Converts the passed in comparison operator to a string usable in a query.
(Inherited from DbSpecificCreatorBase.) | |
ConvertExpressionOperator |
Converts the passed in expression operator (exop) to a string usable in a query
(Inherited from DbSpecificCreatorBase.) | |
ConvertExpressionToQueryFragment |
Converts the expression to a query fragment and adds the parameters created during this process to the passed in parametercollection
(Inherited from DbSpecificCreatorBase.) | |
ConvertFieldToRawName |
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.) | |
ConvertParameterOutputValueToRealValueT |
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.) | |
ConvertSetOperator |
Converts the passed in set operator to a string usable in a query
(Inherited from DbSpecificCreatorBase.) | |

(Overrides DbSpecificCreatorBaseCreateDynamicQueryEngine.) | |
CreateFieldName(IEntityFieldCore, IFieldPersistenceInfo, String, String, Boolean) |
Creates the name for the field, and takes into account an aggregate function present and an expression present. If one or both are present, the
field is replaced with (expression) or surrounded with (aggregate) the function (if applyAggregateFunction is true).
(Inherited from DbSpecificCreatorBase.) | |
CreateFieldName(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.) | |

(Inherited from DbSpecificCreatorBase.) | |
CreateFieldNameSimple(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.) | |
CreateFieldNameSimple(IFieldPersistenceInfo, String, Boolean) |
Creats a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is

CreateHintStatement | Obsolete.
Creates the hint statement for the hint passed in.
(Inherited from DbSpecificCreatorBase.) | |
CreateLikeParameter |
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.

(Inherited from DbSpecificCreatorBase.) | |
CreateObjectName(IFieldPersistenceInfo) |
