The best solution starts by implementing your own Mapper class, in
which you can dynamically configure the datasource based on App.config
or Web.config, depending on the kind of application you're building.
In the example above I'm configuring the connection through the
InitMapper() method:
protected static void InitMapper()
{
DomSqlMapBuilder builder = new DomSqlMapBuilder();
XmlDocument sqlMapConfig =
Resources.GetConfigAsXmlDocument("SqlMap.config");
((sqlMapConfig["sqlMapConfig"]["database"]["dataSource"]).Attributes[1]).Value
= "Data Source=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = " +
ConfigurationManager.AppSettings["DataHost"] + ")(PORT = " +
ConfigurationManager.AppSettings["DataPort"] + "))(CONNECT_DATA =
(SERVER = DEDICATED)(SID = " +
ConfigurationManager.AppSettings["DataOSID"] + ")));User ID=" +
ConfigurationManager.AppSettings["DataUser"] + ";Password=" +
ConfigurationManager.AppSettings["DataPass"];
_Mapper = builder.Configure(sqlMapConfig) as SqlMapper;
}
My SqlMap.config just has this information related to the datasource
<database>
<provider name="oracleClient1.0"/>
<dataSource name="MyPoolName" connectionString=""/>
</database>
In this case you get and XmlDocument from SqlMap.config and then
insert the information from my web.config (this sample is for an
oracle connection):
<add key="DataHost" value="theHost"/>
<add key="DataPort" value="thePort"/>
<add key="DataOSID" value="theOSID"/>
<add key="DataUser" value="myDBuser"/>
<add key="DataPass" value="myDBPass"/>
Finally, the mapper is build with this information:
_Mapper = builder.Configure(sqlMapConfig) as SqlMapper;
The last thing is use this Mapper instead of the classic
Mapper.Instance() when you need to persist:
return yourNamespace.Mapper.Instance().Queryfor{........}
In case you use embedded xml, the only difference from the code is in
how you get the XmlDocument (InitMapper() method)
XmlDocument sqlMapConfig =
Resources.GetEmbeddedResourceAsXmlDocument("sqlMap.config,
your.assemblie");
