Check each query filter, including its field name, operator, and filter value.
检查每一个查询筛选，包括它的字段名，操作者以及筛选值。
In the Data Type Selection dialog, shown in Figure 16, specify Loan in the filter field to filter by business items in the sample Loan project, and select the appropriate business item.
在Data Type Selection对话框(如图16所示)中，在过滤字段中指定Loan，按照样例贷款项目中的业务项目过滤，然后选择适当的业务项目。
Therefore, if a query filter field is one of these types, and the associated table is large, the query can be very slow.
因此，如果查询筛选字段是这种类型中的一个，而相关的表格很大，那么查询的速度会非常慢。
