ProjectionLiteral Class |
Simple class which is used to emit a literal value into the projection. It subclasses dbfunctioncall as that's the class to
use to emit a custom SQL fragment into the query, however we need to specialize it to avoid the () suffix for a function call.

SyntaxThe ProjectionLiteral type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | ProjectionLiteral |
Initializes a new instance of the ProjectionLiteral class.
|
Properties| Name | Description | |
|---|---|---|
 | AliasToUse |
Gets or sets the alias to use. This is the alias of the element it represents when that element is a nested query. Null otherwise.
|
| CatalogName |
Gets or sets the name of the catalog the function is located in. Can be ignored on databases which don't support catalogs.
(Inherited from DbFunctionCall.) |
| DatabaseParameters |
The list of database parameters created when the DbFunctionCall was translated to text usable in a query. Only valid after a succesful call to ToQueryText
(Inherited from DbFunctionCall.) |
| DatabaseSpecificCreator |
Object which will be used to create valid parameter objects, field names, including prefix/postfix characters,
and conversion routines, and field names, including prefix/postfix characters.
Uses the strategy pattern so the generic code can work with more than one target database.
(Inherited from DbFunctionCall.) |
| FieldPersistenceInfos |
Per field in FunctionParameters, this list contains the fieldPersistenceinfo object. If a parameter in FunctionParameters is not an IEntityFieldCore implementing
object, the value for that parameter is null/Nothing.
(Inherited from DbFunctionCall.) |
| FunctionName |
Gets or sets the name of the function to call or pre-formatted function call string. This is without catalog or schema name.
(Inherited from DbFunctionCall.) |
| FunctionParameters |
Gets the function parameters to pass to the function. You can pass fields and values to the function as parameters. A field can have a function call and/or
expression applied to make nested function calls possible.
(Inherited from DbFunctionCall.) |
| SchemaName |
Gets or sets the name of the schema the function is located in. Can be ignored on databases which don't support schemas.
(Inherited from DbFunctionCall.) |
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToQueryText |
Retrieves a ready to use text representation of the contained function call
(Inherited from DbFunctionCall.) |
| ToQueryText(Boolean) |
Retrieves a ready to use text representation of the contained function call
(Overrides DbFunctionCallToQueryText(Boolean).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Explicit Interface Implementations| Name | Description | |
|---|---|---|
  | IXmlSerializableGetSchema |
This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the XmlSchemaProviderAttribute to the class.
(Inherited from DbFunctionCall.) |
| IXmlSerializableReadXml |
Generates an object from its XML representation.
(Inherited from DbFunctionCall.) |
| IXmlSerializableWriteXml |
Converts an object into its XML representation.
(Inherited from DbFunctionCall.) |
 | IExpressionDatabaseSpecificCreator |
Object which will be used to create valid parameter objects, field names, including prefix/postfix characters,
and conversion routines, and field names, including prefix/postfix characters.
Uses the strategy pattern so the generic code can work with more than one target database.
(Inherited from DbFunctionCall.) |
| IExpressionLeftOperand |
Gets the left expression operand. Set by the constructor used.
(Inherited from DbFunctionCall.) |
| IExpressionOperator |
Gets the operator of the expression. Not valid (ExOp.None) if RightOperand is null. Set by the constructor used.
(Inherited from DbFunctionCall.) |
| IExpressionParameters |
The list of parameters created when the Expression was translated to text usable in a query. Only valid after a succesful call to ToQueryText
(Inherited from DbFunctionCall.) |
| IExpressionReadXml |
Deserializes the data on the xml reader into an expression instance
(Inherited from DbFunctionCall.) |
| IExpressionRightOperand |
Gets the right expression operand. Set by the constructor used.
Can be null
(Inherited from DbFunctionCall.) |
| IExpressionToQueryText |
Retrieves a ready to use text representation of the contained function call
(Inherited from DbFunctionCall.) |
| IExpressionToQueryText(Boolean) |
Retrieves a ready to use text representation of the contained function call
(Inherited from DbFunctionCall.) |
| IExpressionWriteXml |
Serializes object as xml to the writer specified.
(Inherited from DbFunctionCall.) |
