OpenEdge Data Management: DataServer for Microsoft SQL Server

Use the PRGRS_CONNECT parameter in the following cases:
Connecting a schema holder
• To establish complex connections that require more than the Physical Database Name
(-db), User ID (-U), and Password (-P) parameters, as follows:
CONNECT datasrc-name -ld logical-datasrc-name -dt MSS
-Dsrv
PRGRS_CO,DSN=datasrc-name;server=servername;UID=name;PWD=password;.
For datasrc–name, supply the name of the MS SQL Server database. Server is a
driver-specific keyword. The -Dsrv connection string is passed directly to the data source.
The DataServer does not modify this value.
• To connect to a MS SQL Server database whose name has a blank space, which is not
allowed by OpenEdge, substitute the characters &^ for the illegal characters in the data
source name. OpenEdge ignores datasrc–name when you use PRGRS_CONNECT; however,
you must supply it to pass syntax validation. Supply the name as part of the connection
string for PRGRS_CONNECT, as follows:
CONNECT datasrc-name -ld logical-database-name -dt MSS
-Dsrv PRGRS_CO,data-&^source&^name;.
• To connect to the MS SQL Server database using the ODBC driver as a guide, specify an
empty PRGRS_CONNECT, which tells the ODBC driver to handle the entire connection
process interactively. For example:
CONNECT datasrc-name -ld logical-name -dt MSS
-Dsrv PRGRS_CO,;.
To simplify your PRGRS_CONNECT string, you can specify a File DSN. When you configure
access to your MS SQL Server database, specify a File DSN and then reference that file in your
connect string. For example:
CONNECT datasrc-name -ld logical-name -dt MSS
-Dsrv PRGRS_CO,FILEDSN=dsn-filename;.
Binding with connection and startup parameters
Binding settings determine how data is pulled from the data source by the DataServer. When
binding is turned on, query results are copied directly into the DataServer’s memory,
eliminating the need to do post-query calls to retrieve the data. When binding is not enabled,
queries run independent of the data retrieval, and subsequent calls to the data source are required
to retrieve the data.
