How to use MySQL and MSSQL together in the grails datasource? - mysql

Question

I have an grails application that uses MySQL for authentication purpose and another application that uses MSSQL for database stuff. I need to combine these together as one application. The datasource for MySQL contains the following
dataSource {
pooled = true
driverClassName = "org.h2.Driver"
username = "sa"
password = ""
}
The datasource for application using MSSQL contains the following
dataSource {
pooled = true
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver" //jdbc driver downloaded from internet: sqljdbc4.jar and sqljdbc_auth.dll (see DisplayHistorical/grails-app/lib)
dialect = "org.hibernate.dialect.SQLServer2008Dialect"
ClassName = "org.hsqldb.jdbcDriver" //Original Code
// enable loggingSql to see sql statements in stdout
loggingSql = true
}
How would I combine these? I looked at the tutorial mentioned on this site (How do you access two databases in Grails) but it doesnt talk about adding the drivers

If you follow the link provided earlier, then you would end up with a datasource configuration like below:
environments {
production {
dataSource_authentication {
pooled = true
url = "jdbc:mysql://yourServer/yourDB"
driverClassName = "com.mysql.jdbc.Driver"
username = "yourUser"
password = "yourPassword"
........
}
dataSource {
pooled = true
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
dialect = "org.hibernate.dialect.SQLServer2008Dialect"
........
}
}
}
Where ever required you can use the authentication datasource explicitly.
