RelOptUtil.inferViewPredicates介绍

[英]Decomposes the WHERE clause of a view into predicates that constraint a column to a particular value.

This method is key to the validation of a modifiable view. Columns that are constrained to a single value can be omitted from the SELECT clause of a modifiable view.
[中]将视图的WHERE子句分解为将列约束为特定值的谓词。
此方法是验证可修改视图的关键。可以从可修改视图的SELECT子句中忽略约束为单个值的列。
