DbSpecificCreatorBase Methods |
The DbSpecificCreatorBase type exposes the following members.
Name | Description | |
---|---|---|
AddParameterToScopeTracker |
Adds the parameter to scope tracker.
| |
AppendEscapeClauseForLikePredicate |
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.
| |
AppendJoinSideToJoinFragments |
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.
| |
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.
| |
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)
| |
ConstructCallToAggregateWithFieldAsParameter |
Constructs a call to the aggregate function specified with the field name specified as parameter.
| |
ConvertComparisonOperator |
Converts the passed in comparison operator to a string usable in a query.
| |
ConvertExpressionOperator |
Converts the passed in expression operator (exop) to a string usable in a query
| |
ConvertExpressionToQueryFragment |
Converts the expression to a query fragment and adds the parameters created during this process to the passed in parametercollection
| |
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.
| |
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.
| |
ConvertSetOperator |
Converts the passed in set operator to a string usable in a query
| |
ConvertSortOperator |
Converts the passed in sort operator to a string usable in a query
| |
CreateCommand |
Creates a new command.
| |

Creates a new command instance
| |
CreateDynamicQueryEngine |
Creates a new dynamic query engine instance
| |
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).
| |
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);
| |
CreateFieldName(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.
| |
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.
| |
CreateFieldNameSimple(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.
| |
CreateHintStatement | Obsolete.
Creates the hint statement for the hint passed in.
| |
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.
| |
CreateNewAliasScope |
Creates a new alias scope and makes it active.
| |
CreateObjectName(IFieldPersistenceInfo) |
Creates a valid object name (f.e. a name for a table or view) based on the passed in IFieldPersistenceInfo implementation. The fieldname is
ready to use in queries and contains all pre/postfix characters required.
| |
CreateObjectName(String, String, String) |
Creates a valid object name (e.g. a name for a table or view) based on the fragments specified. The name is ready to use and contains
all alias wrappings required.
| |
CreateParameter(ParameterDirection, Object) |
Creates a parameter based on the direction passed in and the value passed in.
| |
CreateParameter(ParameterDirection, Object, String) |
Creates a parameter based on the direction passed in and the value passed in.
| |
CreateParameter(IEntityFieldCore, IFieldPersistenceInfo, ParameterDirection) |

| |
CreateParameter(IEntityFieldCore, IFieldPersistenceInfo, ParameterDirection, Object) |
Creates a valid Parameter based on the passed in IEntityFieldCore implementation and the passed in IFieldPersistenceInfo instance
| |

Creates a new, filled parameter.
| |
CreateParameterInstance(String) |
Creates a new parameter instance.
| |
CreateParameterInstance(Object, String) |
Creates a new parameter instance. It sets the value but doesn't set the type so the parameter type depends on the value.
| |
CreateParameterInstance(String, Object) |
Creates a new parameter instance (with direction: input)
| |
CreateParameterInstance(String, ParameterDirection, Object) |
Creates a new parameter instance.
| |

FindRealAlias(String, String, String) |
Finds the real alias for the entity + objectalias combination. A real alias is necessary as an entity mapped onto multiple tables (through inheritance)
is aliased with a single object alias but each target has to have a different real alias. Checks all scopes.
| |
FindRealAlias(String, String, String, Boolean) |
Finds the real alias for the entity + objectalias combination. A real alias is necessary as an entity mapped onto multiple tables (through inheritance)
is aliased with a single object alias but each target has to have a different real alias.
| |
