SQL2GMS
To create a new data source, click the Add button, select a driver, give it a name (this is the DSN name)
and configure the data source.
7 Reading from an MS Access Database
There are several ways to export data from an SQL database into a GAMS include file:
1. Export a CSV (Comma Separated Values) file using Access Export. See http://www.gams.com/
~erwin/interface/interface.html for an example.
2. Use the MDB2GMS tool.
3. Use SQL2GMS with a configured ODBC data source. The connection string will look like: “
DSN=mydsn”.
4. Use SQL2GMS with a DSN-less ODBC connection. In this case we need to specify both the
driver and the location of the database file explicitly in the connection string. The connection
string will look like:
“Driver={Microsoft Access Driver (*.mdb)};Dbq=D:\data\mydata.mdb“.
5. Use SQL2GMS with an OLE DB driver. The connection string can look like:
“Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\data\mydata.mdb“
8 Reading from an MS Excel spreadsheet
There are numerous ways to export data from an Excel spreadsheet into a GAMS include file:
1. Export a CSV (Comma Separated Values) file using Excel Export. See http://www.gams.com/~erwin/
interface/interface.html for an example.
