Class AstCandidateKeyProfileRequestNode

The AstCandidateKeyProfileRequestNode type corresponds directly to the candidate key data profile in the SQL Server Integration Services data profiling task, which will report which column(s) have unique values across rows and could consequently serve as keys.

Constructors

AstCandidateKeyProfileRequestNode(IFrameworkItem)

Initializes a new instance of the AstCandidateKeyProfileRequestNode class with the specified parent node.

Fields

ScopedNamePrefixBackingStore
IsScopeImported

Properties

FriendlyTypeNameStatic

Gets the friendly name of the type of this node

KeyColumns

This is a collection of names of columns that will be examined as candidate key columns for the table.

KeyColumnsDefaultValue

Gets the default value for the KeyColumns property

KeyStrengthThreshold

This value specifies the threshold for key strength that must be satisfied before key strength is reported. This value must be specified in conjunction with a ThresholdSetting of 'Specified'. The default is 0.95.

KeyStrengthThresholdDefaultValue

Gets the default value for the KeyStrengthThreshold property

MaxNumberOfViolations

This value specifies the maximum number of unique key violations to report. If ThresholdSetting is 'Exact', then this property is ignored (as it is implied to be 0). The default is 100.

MaxNumberOfViolationsDefaultValue

Gets the default value for the MaxNumberOfViolations property

ThresholdSetting

This value specifies the conditions under which the strength of a given candidate key will be reported. The default is 'Specified'.

ThresholdSettingDefaultValue

Gets the default value for the ThresholdSetting property

Connection

This value specifies the connection that will be used to access the target table.

Table

This value specifies a direct connection to the table that will examined by the data profile task.

SchemaId

This value specifies the name of the schema that contains the table that will examined by the data profile task. This property is used in conjunction with TableId when the table cannot be referenced by the Table property, because it has not been modeled in the Biml project.

TableId

This value specifies the name of the table that will examined by the data profile task. This property is used in conjunction with SchemaId when the table cannot be referenced by the Table property, because it has not been modeled in the Biml project.

SchemaIdDefaultValue

Gets the default value for the SchemaId property

TableIdDefaultValue

Gets the default value for the TableId 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

BindingScopeBoundaries()

Retrieves the permitted scope boundaries to bind references from this node.

Duplicate()

Creates a duplicate of the current node

Duplicate(IFrameworkItem)

Creates a duplicate of the current node with the specified parent item

GetDefaultValue(String)

Retrieves the default value for the property with the name propertyName

GetDefaultValue<T>(String)

Retrieves the default value for the property with the name propertyName

StructureEquals(Object)

Compares this node to the provided object to determine if all defined children and references are equal.

GetSchemaLocalName()

Retrieves the local XML element name that corresponds to this node in Biml code.

GetAllItemsReferencedByDefinedSuccessors()

Builds a list of all items referenced by this node and its successors. Each tuple in the returned list represents a FrameworkItemReference. The first item is the ReferencingItem, the second item is the property name, and the third item is the ReferencedItem.

BindReference(SymbolTable, String, Boolean, String, Int32, Boolean)
ToString()

Returns a string that represents the current object. In this case, it is the Name of the node.

RemoveScopedNameChangedEventListener(IReferenceableItem, EventHandler<VulcanPropertyChangedEventArgs>)

Removes the scoped name changed event handler from the specified referenceable item.

FirstChildOfType<TChild>()

Gets the first defined descendant node of the specified type

RemoveFromParent()

Removes this node definition from its parent

DefinedAstNodes()

Retrieves a collection of nodes that have been defined as direct children of the current node.

GetJson()

Generates a JavaScript Object Notation (JSON) representation of the current node

GetExternalJson()

Generates a JavaScript Object Notation (JSON) representation of the current node

GetJson(Boolean, Boolean, Boolean, Boolean, Boolean)

AncestorDistance(IFrameworkItem)

Retrieves the number of steps between this node and the nearest shared ancestor with the specified relative node.

FirstThisOrParent<TAstNode>(Type)

Retrieves the first parent or ancestor node (including this node) of the specified type with the specified custom attribute type

AllDefinedSuccessors()

Retrieves the collection of all nodes defined as a child of this or any successor node or the current node
