-------------------------------------
[~tonytao0505] Hi.Can you describe in detail how to reproduce this
problem.Because I use
{code:java}
// select * from \"foodmart\".\"sales_fact\" s ,\"hr\".\"emps\" e where e" +
".\"empid\" = s.\"cust_id\" and s.\"prod_id\" between 11.0 and 21.0
{code}
had succeed. and s."prod_id" is float. I directly use JdbcExample and change
{code:java}
public static class SalesFact {
public final int cust_id;
public final float prod_id;
public SalesFact(int cust_id, float prod_id) {
this.cust_id = cust_id;
this.prod_id = prod_id;
}
}{code}
> FLOAT was not supported in method "appendAsJava" of RexLitera.java
