untyped

Without some form of external information, there was no way to know what type of object was linked by an untyped reference.

As a consequence, an untyped dataset has no inherent structure.

The strongly typed DataSet offers advantages over the untyped DataSet in terms of speed and easy maintainability.

The result of query execution consists of the elements of an untyped java. util. List.

An untyped dataset is an instance of the DataSet class that you create in a form or component.

You can use user-defined properties as a simple, unstructured and untyped extension mechanism.

When using SOAP as a remote procedure call (RPC) system, the SOAP parameters can be typed or untyped.

Otherwise, the XML instance is called untyped.

When working with untyped datasets, the programmer would not learn of the error until run time.

Explicitly declaring data types is unambiguous, and typed code is easier to read and maintain than untyped code.

Variables are untyped, so the object constructor might begin with code shown in Listing 1.

You cannot create records in an untyped dataset at design time; you can populate a dataset only at run time.

You do not need to use typed variables, but programs that use untyped variables are slower and more prone to errors.

Adds an instance of a typed or untyped dataset to the form or component.

There are differences in maintenance and performance when referring to columns in an untyped DataSet.

Allows you to place a unique constraint on one or more columns in a table in an untyped dataset.

This dialog box appears when you are using the Properties window to edit the Tables property of an untyped dataset on a form or component.

In some cases, a memory reference is untyped. One example is an immediate value (Buffer) enclosed in square brackets.

to define table constraints only in an untyped dataset.

The wrapper class is named xml for untyped XML parameters, but uses a generated name for typed XML parameters.

All columns must be either typed to an XML schema or untyped.

Even though typed datasets have many advantages, there are a variety of circumstances under which an untyped dataset is useful.

Implicit casting is allowed only for numeric types and untyped atomic types.

Assume that you want to change the type of an [n]text or image column, XYZ in table R, to untyped XML.

If no typing information is available, XQuery handles the data as untyped.

This creates a new untyped reference component called ReferencePartner.

You can create indexes on typed and untyped XML data columns using a new DDL statement.

This problem occurs frequently with untyped data.

For typed or untyped xml, inserting the attribute xml: base will fail.

For information about typed XML, see Typed vs. Untyped XML.

The following query is specified against an untyped XML instance.

You can use the Properties window to create the structure of the untyped dataset.

Select the untyped dataset in the form or component.

The instructions below describe how to create an untyped dataset using the Component Designer while editing a form or component.

Explains how to declare typed and untyped variables and constants and how to initialize them.

You can change an xml type column from untyped XML to typed XML.

The method returns an instance of untyped XML.

String type is the implied type of all untyped variables.

As a result, typed XML data replaces previously untyped XML data.

You can bind to either typed or untyped datasets.

This includes data sources such as arrays, collections, untyped datasets, and data readers.

The following examples show how to locate and modify rows in both typed, and untyped datasets.

This happens because untyped datasets do not provide schema, so the wizard has insufficient information to create the data source.

This is because untyped datasets do not provide schema, so the wizard does not have enough information to create the data source.

For untyped datasets, use code similar to the following

For example, consider the following line of code that accesses a data member in an untyped dataset
