Connecting the Loop Operations to the Cast Operations

The XML formatted timestamp and values need to be transformed into data types that will work in a SQL view environment. The NMTOKEN values need to be converted to timestamp and the xs:decimal values need to be converted to DOUBLE.

To connect loop operations to cast operations

1.

Open the NameValue transform.

2.

Connect loop system:Value to the source in cast.

3.

Double-click cast to open the Choose Data Type editor.

4.

From the drop down list select Decimal > DOUBLE.

5.

For the minimum and maximum values, accept the defaults of:

-1.7976931348623157E+308  and 1.7976931348623157E+308

6.

Connect cast result to the out v_Temp Value parameter.

7.

Repeat these steps to create the cast operations for each of the loop system:Value parameters and connect them to the out v_Pressure and v_Concentration Value parameters.

For example, your transform should have cast operations and connections similar to the following:

8.

Connect loop system:Timestamp to the source in a cast operation.

9.

Double-click cast to open the Choose Data Type editor.

10.

From the drop down list select Time > TIMESTAMP.

11.

Connect cast result to the out v_Temp Timestamp parameter.

12.

Repeat these steps to create the cast operations for each of the loop system:Timestamp parameters and connect them to the out v_Pressure and v_Concentration Timestamp parameters.

For example, your transform should have cast operations and connections similar to the following:

13.

Save the transformation.
