委托翻译链接
Delegate Translator Chaining
我试图通过链接 VDB.xml 来委派翻译人员，但在调用后出现错误。
委托翻译器假设拦截对下面的实际委托翻译器的调用并执行计算。
计算由 TEIID_SESSION 中的 属性 集驱动，作为有效负载与语句对象
一起传递
我的vdb.xml:
<source connection-jndi-name="java:/SourceModel" name="SourceModel" translator-name="delegate"/>
<translator name="delegate" type="calcDelegate">
<property name="delegateName" value="sqlserver" />
</translator>
当我在 teiid_session 中设置 属性 并在 SQL 客户端中设置 运行 查询时，出现以下错误：
