This topic discusses application of the Transform Dialog with Tables on a datetime field in a table. See the Transform Dialog and Transform Templates topics for use and for links to lists of templates for other data types for tables and use of the Transform Dialog with other components, such as Drawings and Images.
Copy |
Copy the source field into the target field.
Example: Copy Calendar into Temp_datetime.
|
Maximum Value |
Take the maximum, that is the greater value, of either the source field or the comparison field and save into the target field.
Example: Put in Temp_datetime the Maximum Value of Calendar or #12/15/2016 12:00:00#.
|
Minimum Value |
Take the minimum, that is the lesser value, of either the source field or the comparison field and save into the target field.
Example: Put in Temp_datetime the Minimum Value of Calendar or #12/15/2016 12:00:00#.

Transform Templates - Drawings
Transform: Center and Centroids
Example: Two Drawings from the Same Table - Take a table with a geom field that is visualized by a drawing. Add a second geom field to the table and create an rtree index on that field so it can be visualized by a drawing. Copy the first drawing, paste it and adjust the pasted copy so it uses the second geom field. Demonstrate how to use the Transform dialog to show "live" modifications in the second drawing compared to the first drawing.
Example: Copy one Column into Another Column with Transform - How to use the Transform dialog to copy the contents of one column in a table into another column, but only for selected records. Uses the Products table from the Nwind example data set.
Example: Transform Field Values using an Expression in the Transform Dialog - How the Expressions tab of the Transform Dialog may be used to change the values of fields. We include an example of changing the price of selected products and using two different Transform dialogs open at the same time for two different table windows.
Example: Construct JSON String using Select and Transform - Use the Select and Transform dialogs to manually construct a JSON string using values from other fields in a table. Shows how we can manipulate text to build desired contents in a field.
Example: Edit a Drawing with Transform Dialog Templates - In this example we open a drawing and edit objects in the drawing using the Transform dialog Template tab. Includes examples of using the Add Component button and also the Edit Query button.
Example: Use a Transform Dialog Expression to Create Buffers in a Drawing - Use the Expression tab of the Transform Dialog to create three different sizes of buffers for different lines in a drawing and then automatically create a query which does the same thing. Includes examples of using the Add Component button and also the Edit Query button.
Example: Clip Areas with a Transform Dialog Expression - Use the Expression tab of the Transform dialog to clip areas in a drawing to fit within horizontal bounds. Includes examples of using the Add Component button and also the Edit Query button.
Example: Smooth Lines with a Transform Dialog Expression - Use the Expression tab of the Transform dialog to make lines smoother in a drawing so that longer lines are smoothed more. Includes examples of using the Edit Query button to show how different queries are created automatically depending on if we want to update a field or to add a new component.
Example: Transfer Options and Merge Areas - Using the Merge Areas Transform dialog template, an exploration of the difference between using Copy and Sum for transfer options.
