OpenEdge Data Management: DataServer for Microsoft SQL Server

Chapter 7: The DataServer Tutorial
The Data Dictionary displays the standard MS SQL Server names for data types
and not the native ODBC data source names. Using the Data Dictionary, you can
make the following changes:
• Change the data type or the format in which OpenEdge displays the data. For
example, choose the MS SQL Server decimal data type, which in turn
defaults to the OpenEdge INTEGER data type mapping. However, you can
change the decimal mapping to either the OpenEdge INTEGER or INT64
data type instead. (The previous Field Properties dialog box shows the
DECIMAL data type with the INT64 data type option selected.) For more
information about optional settings for data types, see the “Data types”
section on page 71 and Appendix C, “Data Type Details.”
• For CHARACTER fields that are not indexed, you can change the case
sensitivity.
Note: You cannot create fields or add mandatory or extent properties to them.
5. Choose DataServer to view the field name and position as stored in the data
source. A dialog box similar to the following appears:
Note: You cannot change data source information using the Data Dictionary. For
example, the total_paid field is named total_paid in the database.
6. Choose OK.
7. When you are done making changes, choose OK to return to the Data Dictionary
main window.
Note: You can override field-level validation expressions in your application by
including the appropriate ABL statement.
