Class AstColumnPatternProfileRequestNode
The AstColumnPatternProfileRequestNode type corresponds directly to the column pattern data profile in the SQL Server Integration Services data profiling task, which will compute a collection of patterns that describe the values in a character-based column.

Properties
| Properties | Description |
|---|---|
| CaseSensitive | This value specifies whether the patterns will be evaluated against column values using case sensitive comparisons. |
| CaseSensitiveDefaultValue | Gets the default value for the CaseSensitive property |
| Column | This value specifies the name of the column whose values will be profiled against the specified pattern. |
| ColumnDefaultValue | Gets the default value for the Column property |
| Delimiters | This value specifies the characters that will be replaced with spaces before tokenizing. The default include tab (\t), carriage return (\r), and line feed (\n). |
| DelimitersDefaultValue | Gets the default value for the Delimiters property |
| FriendlyTypeNameStatic | Gets the friendly name of the type of this node |
| MaxNumberOfPatterns | This value specifies the maximum number of patterns that will be computed by the profile up to 100. The default is 10. |
| MaxNumberOfPatternsDefaultValue | Gets the default value for the MaxNumberOfPatterns property |
| PercentageDataCoverageDesired | This value specifies the percentage of data in the column that should be covered by the generated patterns from 0 to 100. The default is 95. |
| PercentageDataCoverageDesiredDefaultValue | Gets the default value for the PercentageDataCoverageDesired property |
| Symbols | This value specifies any symbols or punctuations that should be retained as part of the patterns. The default includes ,.;:-"'`~=&/@!?()<>[] |
| SymbolsDefaultValue | Gets the default value for the Symbols property |
| TagTable | This value specifies a direct connection to the tag table which will tag 2 string columns - Tag and Term. |
| TagTableConnection | This value specifies a direct reference to the ADO.NET connection that contains the tag table. |
| TagTableSchemaId | This value specifies the name of the schema that contains the tag table. This property is used in conjunction with TableId when the tag table cannot be referenced by the TagTable property, because it has not been modeled in the Biml project. |
| TagTableSchemaIdDefaultValue | Gets the default value for the TagTableSchemaId property |
| TagTableTableId | This value specifies the name of the tag table. This property is used in conjunction with TableId when the tag table cannot be referenced by the TagTable property, because it has not been modeled in the Biml project. |
| TagTableTableIdDefaultValue | Gets the default value for the TagTableTableId 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. |
