Class AstMultipleColumnTableReferenceNode
Multiple-column table references are used to create a local column with a relationship to a multiple-column key of a regular table. Multiple-column table references can be used with foreign keys having any number of columns. Use table reference columns for a version of table references that is optimized for single column keys.

Properties
| ForeignColumn | This value is a reference to the column on the foreign table that will be connected to the local column in this table. There should be additional multiple column table reference columns that point to other columns in the same table to complete the reference. |
| ForeignTable | Gets a reference to the parent table of the column referenced by the this column |
| FriendlyTypeNameStatic | Gets the friendly name of the type of this node |
| IsComputed | Indicates whether this is a computed column |
| IsLargeObject | Indicates whether this column uses a large object (LOB) data type |
| MultipleColumnTableReferenceGroupName | All multiple column table reference columns that point to foreign columns in the same foreign key must have the same MultipleColumnTableReferenceGroupName. |
| MultipleColumnTableReferenceGroupNameDefaultValue | Gets the default value for the MultipleColumnTableReferenceGroupName property |
| ReferencedColumn | For reference columns, returns the referenced column |
| ForeignKeyNameOverride | When the ForeignKeyConstraintMode property is properly set, the Biml compiler automatically creates a foreign key constraint name based on the names of the relevant tables and columns. To override the automatically generated foreign key constraint name, supply the value in this property. |
| ForeignKeyConstraintMode | This value determines whether a foreign key constraint will be created for this table reference column and whether the created constraint is enforced by the database. |
| ForeignKeyNameOverrideDefaultValue | Gets the default value for the ForeignKeyNameOverride property |
| ForeignKeyConstraintModeDefaultValue | Gets the default value for the ForeignKeyConstraintMode property |
| IsAutoGenerated | Indicates whether the value of column is automatically generated |
| IsAssignable | Indicates whether this column is assignable. Generally false only if the column is computed, auto-generated, participates in an identity, or has been fixed by a constraint |
| QualifiedName | Gets the fully qualified T-SQL name for this column |
| IsIdentityColumn | Indicates whether this column participates in an identity |
| DefaultValue | Gets or sets the default value for this column. This will be emitted as a default value constraint. |
| IsUsedInKey | Indicates whether this column is used in any key |
| IsUsedInPrimaryKey | Indicates whether this column is used in a primary key |
| IsUsedInIndex | Indicates whether this column is used in any index |
| ReferencedDataType | For reference columns, returns the referenced column's data type |
| ReferencedCustomType | For reference columns, returns the referenced column's custom data type |
| ReferencedLength | For reference columns, returns the referenced column's length |
| ReferencedPrecision | For reference columns, returns the referenced column's length |
| ReferencedScale | For reference columns, returns the referenced column's length |
| DataType | This value specifies the type of the data stored in this column using the unified type system. The type values include all of those types commonly used in Microsoft SQL Server table definitions. |
| Length | (Set to -1 to indicate MAX length). This value specifies the length parameter for the column type associated with this column. This property applies only to column types that support a length specification, such as String and Binary types. |
| Precision | This value specifies the precision parameter for the column type associated with this column. Precision is the number of digits stored for a numeric value. This property applies only to column types that support precision, such as Decimal. |
| Scale | This value specifies the scale parameter for the column type associated with this column. Scale is the number of digits to the right of the decimal point in a numeric value. This property applies only to column types that support precision, such as Decimal. |
| CustomType | This value specifies the type of a column when the main column type has been set to Custom. This permits the specification of less commonly used SQL Server column types. A complete list of allowed types is available at http://msdn.microsoft.com/en-us/library/ms127023%28SQL.90%29.aspx |
| Computed | This value specifies a computed value for the column using Transact-SQL expression syntax. Computed column specifications conform to all SQL Server computed column rules as described at http://msdn.microsoft.com/en-us/library/ms191250.aspx |
| Default | This value specifies a default value for the column using Transact-SQL constant expression syntax. |
| ScdType | This value specifies the slowly changing dimension type for the column. The value determines the behavior of the table when a row with a matching unique key value is added to the table. This behavior is enforced in the various Task and Dataflow transformations that interact with this table. |
| IsNullable | This value specifies whether null values are accepted for the column. |
| ReadOnly | Advanced Feature: Use at your own risk. Specifies that the column should be treated as a read-only column. This will automatically remove the column from assignment from Merge statements and other auto-generated code paths. Computed columns and rowversion columns are two examples of data types which are read-only. |
| IdentitySeed | This value specifies the starting value for an identity column. When the first row is inserted into the table, this value is used. Both seed and increment must be specified if either is explicitly specified. The default value is 1. |
| IdentityIncrement | Set IdentityIncrement to a non-zero value to enable this column as an IDENTITY. This value specifies the amount by which the Identity value is incremented when a row is inserted. Removing this property or setting the value to 0 will remove the IDENTITY specification for this column. |
| CheckConstraint | The check constraint associated with this column. |
| DefaultConstraintName | This value specifies the name that should be used for the default value constraint for this column in the database. If the Default property has not been specified, the value of this property will be ignored. |
| CodePage | This value specifies the integer index for the codepage of the dataflow column. This property applies only to dataflow column types that support code pages, such as strings. Codepages supported by Windows are listed at: http://msdn.microsoft.com/en-us/goglobal/bb964654.aspx. |
| FriendlyName | Provides a convenience property for storing an alternative name for this column. |

| DefaultDefaultValue | Gets the default value for the Default property |
| ScdTypeDefaultValue | Gets the default value for the ScdType property |
| IsNullableDefaultValue | Gets the default value for the IsNullable property |
| ReadOnlyDefaultValue | Gets the default value for the ReadOnly property |

| References | Gets collection of FrameworkItemReference objects, which track rich information about the properties that hold references to this node. |
| NameDefaultValue | Gets the default value for the Name property |
| Guid | |
| Annotations | This is a collection of annotation items that can be used to specify documentation, tags, or other information. Annotations are particularly useful for storing information about nodes that can be used by BimlScript code. |
| ObjectTag | This property provides a general purpose storage mechanism for .NET objects to be associated with AstNode objects. It supplements the annotation system, which is intended for use with string-based metadata. |
| BimlFile | This value specifies the BimlFile in which the Biml code that defines AstNode resides. |
| ItemLabel | Gets a label that can be used to identify this node |
