Table Column Node

How the Table Column Nodes Work

A Table Column node represents a single column in the enclosing relational table.

An Object type table has no columns. When you expand an Object type table node, the object (user-defined type) used by the table is displayed under the table node.

An XML table always has only one column, SYS_NC_ROWINFO$, which is the only table column node that appears under the XML table node.

When you expand an user-defined type column node, the user-defined type appears under the column node.

To perform actions on the Table Column node: right-click this node and from the menu choose the appropriate command. To view the node's properties, select the node and/or click Properties in the node's menu.

Drag and Drop Support

You can automatically generate a query for a table by dragging the table column node onto the Oracle Query Window. Dragging a table column node onto the Oracle Query Window generates a query that selects that column from the corresponding table.

Also, you can automatically generate a query for a table column by dragging the table column node onto the Microsoft Query Designer. This generate a query that selects the column from the corresponding table.

This node can be dragged and dropped into DataSet Designers and XML Schema Designers.
