OFBiz中调jdbc

import org.ofbiz.entity.jdbc.ConnectionFactory;

String helperName = delegator.getGroupHelperName("org.ofbiz");    // gets the helper (localderby, localmysql, localpostgres, etc.) for your entity group org.ofbiz
Connection conn = ConnectionFactory.getConnection(helperName);
Statement statement = conn.createStatement();
statement.execute("SELECT * FROM PARTY");
ResultSet results = statement.getResultSet();

//  通过普通JDBC 的结果集来操作

//Alternatively, you can use the SQLProcessor like this:

SQLProcessor sqlproc = new SQLProcessor(helperName);
sqlproc.prepareStatement("SELECT * FROM PARTY");
ResultSet rs1 = sqlproc.executeQuery();

ResultSet rs2 = sqlproc.executeQuery("SELECT * FROM PRODUCT");
