Properties

Properties	Description
CodePage	This value specifies the integer index for the code page of this converted column type. This property applies only to converted column types that support code pages, such as strings. Code pages supported by Windows are listed at: http://msdn.microsoft.com/en-us/goglobal/bb964654.aspx.
CodePageDefaultValue	Gets the default value for the CodePage property
DataType	This value specifies the type of the converted column using the unified type system.
FastParse	This value specifies whether a column uses SQL Server Integration Services (SSIS) fast parsing routines.
FastParseDefaultValue	Gets the default value for the FastParse property
FriendlyTypeNameStatic	Gets the friendly name of the type of this node
Length	This value specifies the length of the converted column type. This property applies only to converted column types that support a length specification, such as string and binary types.
LengthDefaultValue	Gets the default value for the Length property
Precision	This value specifies the precision or the number of digits in a converted column type. This property only applies to converted column types that support precision, such as decimal.
PrecisionDefaultValue	Gets the default value for the Precision property
Scale	This value specifies the precision, or the number of digits, in a converted column type. This property applies only to converted column types that support precision, such as decimal.
ScaleDefaultValue	Gets the default value for the Scale property
SsisDataTypeOverride	Specifies the SSIS Data Type that should be used for the output column. This value overrides the value specified in the DataType property.
Name	Gets or sets the Name of the column mapping, which corresponds directly to the SourceColumn property
SourceColumn	This value specifies the name of the source column in the data flow path mapping.
TargetColumn	This value specifies the name of the destination column in the data flow path mapping.
IsUsed	This value specifies whether the dataflow column is used.
SortKeyPosition	This value specifies where the parent column is situated in the sort order. For example if the rows were first sorted by 2 other columns, then the value would be 3. If this column was not used for sorting, it's value should be 0.
SourceColumnDefaultValue	Gets the default value for the SourceColumn property
TargetColumnDefaultValue	Gets the default value for the TargetColumn property
IsUsedDefaultValue	Gets the default value for the IsUsed property
SortKeyPositionDefaultValue	Gets the default value for the SortKeyPosition 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
ParentItem	This value specifies the parent of the current node. All nodes must have a valid parent in the Biml framework, except for the root node.
