OpenEdge Data Management: DataServer for Microsoft SQL Server

Initial Programming Considerations
2–26
Table 2–10: Converting ABL datetime types to MS SQL Server data types
(2 of 2)
Source
(MSS)
SMALLDATETIME DATETIME-TZ Straight copy of the date and time
portions of the MSS SMALLDATETIME
with 1 minute accuracy. Time zone will
be set to client time zone context.
DATETIMEOFFSET DATETIME-TZ Straight copy with millisecond accuracy.
1. When a TIME data type in MS SQL Server is mapped to an OpenEdge Datetime data type, the date portion defaults
to TODAY's date unless a valid date is specified for the -Dsrv PRGRS_DATEPART_OVERRIDE switch at
connection time. This switch allows the user to set a date for this conversion other than TODAY's date.
Enabling Datetime data types using the Data Administration tool
The OpenEdge Data Administration tool provides utilities for migrating an OpenEdge database
to a MS SQL Server data source and for pulling definitions from an MS SQL Server data source
into an OpenEdge database, referred to as a schema holder. In doing so, OpenEdge applications
use the DataServer to access and update data stored in MS SQL Server data sources.
The Data Administration tool ensures that utilities can recognize and handle date time data types
supported in starting in MS SQL Server 2008 and later. Those utilities include:
• Update/Add Table Definitions
• Verify Table Definitions
• Schema Migration > OpenEdge DB to MS SQL Server
• Adjust Schema
• Generate Delta.sql OpenEdge to MS SQL Server
• Dump as Create Table Statement
Update/Add Table definitions utility
Target
(OpenEdge) Default Conversion
The Update/Add Table Definitions utility allows you to pull definitions from a table in a foreign
data source. The table may be new or already exist in the schema holder, in which case you can
add definitions or update definitions that are outdated. By default, MS SQL Server DATETIME
and SMALLDATETIME data types are mapped to the OpenEdge DATE data type. The utility allows
you to change the mapping to OpenEdge DATETIME.
Note: Since time zone support is new in 10.2B, any DATETIMEOFFSET column pulled from an
MSS SQL Server 2008 or later database is automatically mapped to DATETIME-TZ by
default.
