Hi, I would like to know if there is any way to reference data from a table in a secondary datasource. My data exists in two data sources, PostgreSQL 7.2 and M$-SQL 2000. I configured the two data sources and I can use CMP to store data into both the data sources through configurations in my META-INF/jbosscmp-jdbc.xml file deployed in my J2EE application and all is well. Some EJB entity beans store (using CMP) and obtain data from one datasource and the other EJB entity beans get obtain and store their data in the other database. My data sources are java:/PostgresDS and java:/MSSQLDS. I am using “raw” SQL statements to get the data from the databases. I can access data from my default datasource (java:/PostgresDS) using plain SQL queries like so “SELECT * FROM PBudgetSummaryLineItemYearEJB where proposalId=? and departmentId=? and userId=? and groupId=?” now I would like to know how I can modify the above query to access data from the other datasource “java:/MSSQLDS”? I am trying not to use CMP for data retrieval using EJB QL.
Thank you. __________________________________________________ Do you Yahoo!? Yahoo!
