DriveWorks Pro 17: Define Tables [send feedback...]

Define Tables

When creating an automation project, it is likely that you've got existing data in databases or spreadsheets that you want to reuse, you can create Tables using the Table Editor which can represent static data, or data which is pulled dynamically from external databases such as Microsoft SQL Server.


Tables

Table Types

DriveWorks allows the following types of table to be created

  • Rollup Data Table - Allows data from embedded child specifications to be passed directly to the table.
  • Simple Table - Creates a blank worksheet in which data can be typed or copied and pasted from compatible sources.
  • Excel data Table - Imports data from an Excel spreadsheet. Once imported the data can be edited directly in DriveWorks.
  • ODBC Data Table - Creates a link to a database that connects using ODBC. See How To: Setup a DSN-Access or How To: Setup a DSN-SQL Server for more information.
  • SQL Server Data Table - Creates a link directly to a SQL Server database. Once selected the wizard will guide you through connecting to all SQL Servers that are visible to the computer.
    The ODBC Data Table and SQL Server Data Table wizards include an option to refresh the data each time the project is opened. Beginning a new specification also opens the project and so the data is refreshed at this time also when this option is checked.

To Add a New Table

  1. Click the Add button on the command bar to launch the Create Table wizard.
  2. Select the Table type from the Template list.

  3. Enter a name for the table.
  4. Select Finish (for Simple Table) to begin entering data.

    OR

  5. Select Next to enter additional set up information for the other table types.

Once the table has been created, the table editor will switch into Edit mode.

In edit mode you can cut/copy/paste data from external systems, and fill in values in a similar way to a traditional spreadsheet.

When you are done, click the OK button to return to the table list.

To Edit a Table

To view or edit the data in an existing table, follow the steps below:

  1. From the Define Tables task, select the table to edit.
  2. Click the View/Edit button on the command bar.
  3. The table view will switch to edit mode.

When editing a table the name is displayed in the Status Bar.

To edit additional set up information (for Excel, ODBC, SQL Server or Rollup data tables):

  1. From the Define Tables task, select the table to edit.
  2. Click the Configure button on the command bar.
  3. The Configure wizard will launch, allowing the additional set up information to be edited.

To Rename a Table

  1. Select the table to rename.
  2. Click the Rename button on the command bar.
  3. Enter the new name.
  4. Press Return to confirm the rename operation.

Renaming a table will scan all rules and replace any occurrence of the old name with the new name.

If DriveWorks detects that this could cause a delay, then the following message will be displayed.

Updating table names in rules is only supported when renaming project tables.

Renaming Group Tables, for example, will not scan every project in the group.

To Delete a Table

  1. Select the table to delete.
  2. Click the Delete button on the command bar.

Using Fractions

When fractions are required in a table, that are to be used in further calculations, include a column where the decimal equivalent of the fraction can be looked up and used in any calculation.

For example:

A Combo Box is required to be populated with a list of sizes using the fraction format. When a size is selected from the combo box, 2.5 is to be added to the value to obtain the overall length.

  1. Create a table with the sizes to be selected from the combo box in one column and the decimal equivalent in the next column
  2. Add a combo box to the user form and use the ListAll function to list all the values from the first column
  3. Create a variable to Lookup the selected size and report the decimal equivalent, and then add 2.5 to this value.
