Properties
| Properties | Description |
|---|---|
| FriendlyTypeNameStatic | Gets the friendly name of the type of this node |
| ComparisonBytes | For choosing a PreferredKey, the table will select the key that requires the smallest number of bytes to compare. This is only in cases where a key cannot first be selected through some other criteria. This property supplies the comparison bytes value. |
| PadIndex | This value determines whether each intermediate level of the index is padded with extra open space in each page. |
| IgnoreDupKey | This value specifies whether incoming rows that have a duplicate key value should produce a warning (and continue) or an error (and terminate). This property applies only for keys where the value of Unique is True. It is useful for enabling large bulk inserts to complete when duplicate rows exist. |
| Clustered | This value specifies whether incoming rows that have a duplicate key value should produce a warning (and continue) or an error (and terminate). This property applies only for keys where the value of Unique is True. It is useful for enabling large bulk inserts to complete when duplicate rows exist. |
| Unique | This value specifies whether each key value is unique. When the value is True, no two rows have the same values across all of the columns participating in the key. |
| Columns | This is a container for key column reference definitions. |
| FillFactor | This value specifies what percentage of each index page the database engine should fill when creating or rebuilding the index. |
| IsEnabled | Enables or Disables this constraint. Disabled constraints will not be generated in the emitted SQL statements but will have metadata available for other use. |
| PadIndexDefaultValue | Gets the default value for the PadIndex property |
| IgnoreDupKeyDefaultValue | Gets the default value for the IgnoreDupKey property |
| ClusteredDefaultValue | Gets the default value for the Clustered property |
| UniqueDefaultValue | Gets the default value for the Unique property |
| FillFactorDefaultValue | Gets the default value for the FillFactor property |
| IsEnabledDefaultValue | Gets the default value for the IsEnabled 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. |
Methods
