| DefaultCodePageDefaultValue | Gets the default value for the DefaultCodePage property |
| DetailedTracingFile | This value specifies the name of the file to be used for TPT detailed tracing. Tracing is automatically enabled when a value is provided for this property. |
| DetailedTracingFileDefaultValue | Gets the default value for the DetailedTracingFile property |
| DetailedTracingLevel | When TPT detailed tracing has been enabled by setting the DetailedTracingFileProperty, this value specifies the type of tracing messages to log to the trace file. |

| MaximumSessionCountDefaultValue | Gets the default value for the MaximumSessionCount property |
| MinimumSessionCount | Specifies the minimum number of sessions that should be created for this component execution. The default is 1. |
| MinimumSessionCountDefaultValue | Gets the default value for the MinimumSessionCount property |
| OutputPath | Gets the output path for this transformation. This is the preferred output path and will automatically connect to any single-input transformation nodes that directly follow it in the Biml file. |
| Query | This value specifies the SQL query to use to load data from the specified connection. |
| QueryBandSessionInfo | Specifies the Teradata queryband expression, which is a collection of user-defined key/value pairs that can be used to identify the source of the query. |
| QueryBandSessionInfoDefaultValue | Gets the default value for the QueryBandSessionInfo property |
| TenacityHours | Specifies the total time in hours that should be waited before failing the execution of this component when the Teradata database is blocked by running too many load jobs. The default is 4 hours. |
| TenacityHoursDefaultValue | Gets the default value for the TenacityHours property |
| TenacitySleep | Specifies the total time in minutes between retry attempts when the Teradata database is blocked by running too many load jobs. The default is 6 minutes. |
| TenacitySleepDefaultValue | Gets the default value for the TenacitySleep property |
| UseDataEncryption | This value specifies whether SQL requests, responses, and other data should be encrypted when communicating with the server. |
| UseDataEncryptionDefaultValue | Gets the default value for the UseDataEncryption property |
| UseExtendedStringColumnsAllocation | This value specifies whether or not extended character buffers should be used when the export table width equals the maximum default. |
| UseExtendedStringColumnsAllocationDefaultValue | Gets the default value for the UseExtendedStringColumnsAllocation property |
| VisibleVariables | Gets a collection of all variable nodes that are available to be used by this transformation. It includes variables defined by this transformation and any tasks/packages that contain this transformation |
| PreferredOutputPath | Gets the preferred output path for the transformation. This output path will support automatic connections to single-input transformations that directly follow in the Biml code |
| DataflowInputs | Gets a collection of all dataflow input paths for this transformation |
| DataflowOutputs | Gets a collection of all dataflow output paths for this transformation |
| ValidateExternalMetadata | This value specifies whether the data flow transformation is validated against columns that originated in external data sources. When server assets such as tables and stored procedures are created during processing, ValidateExternalMetadata is normally set to False, which prevents validation from completing at compile time. |
| LocaleId | This value specifies which locale is used by the dataflow task. |
| ErrorHandling | This value specifies how errors are handled by default in columns processed by the component. This can be overriden at the component or column level for specific cases. |
| DataflowOverrides | Provides a collection of objects to override properties of the component, its input paths, its output paths, and its consituent dataflow columns. |
| ValidateExternalMetadataDefaultValue | Gets the default value for the ValidateExternalMetadata property |
| LocaleIdDefaultValue | Gets the default value for the LocaleId property |
| ScopedName | Gets the scoped name which can be used to uniquely identify this object among other objects of its type |
| SymbolTable | Gets a reference to the symbol table that stores a reference to this and all other named objects in the project |
| SsisSafeScopedName | Returns a version of the ScopedName that has been cleaned of invalid characters for SSIS. |
| SsisSafeName | Returns a version of the Name that has been cleaned of invalid characters for SSIS. |
| Name | Specifies the name of the object. This name can be used to reference this object from anywhere else in the program. |
| 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 |
| 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. |
