3b73572c0f 解决右值引用存在returning语句时core的问题 2023-02-13 15:55:25 +08:00
huyinghao
a5fb68a3a2 在transformSetOperationTree遍历左右子树后，不立即对目标列类型进行处理，而是将targetlist缓存下来，待整棵树遍历完成后，将所有的targetlist汇总，此时每列从对应多个子查询的列类型选出一个合适类型，然后再递归遍历SetOperationStmt，处理每个节点的类型等操作，此时如果节点左右子节点某列类型为NULL，则使用选择出来的类型 
回退所有针对union的修改

修改使允许两列 值为NULL且类型未知union操作后 产生的text类型目标列 可以与其它任意类型的列进行union或union all操作

增加文件末尾行

将添加在末尾的fastcheck用例往上移，避免合并冲突

修改 copy/equal/out/readfuncs.cpp

增加版本控制
