doris insert into和with as 合用

Apache Doris 的 INSERT INTO ... WITH AS（CTE）语法是支持的，但必须将 CTE 包裹在子查询中，或直接在 INSERT INTO ... SELECT 的 SELECT 部分使用，并建议显式指定 WITH LABEL。‌‌

‌标准写法 ‌：INSERT INTO target_table WITH LABEL label_name WITH cte_name AS (...) SELECT ... FROM cte_name;
‌兼容写法 ‌（若上述报错）：INSERT INTO target_table SELECT * FROM (WITH cte_name AS (...) SELECT ...) AS sub;
Doris 要求 ‌CTE 必须作为 SELECT 的一部分 ‌，不能独立于 INSERT INTO ... SELECT 之外使用；
‌**生产环境建议显式指定 WITH LABEL**‌，避免自动生成标签冲突；
CTE 支持多层定义（如 WITH cte1 AS (...), cte2 AS (SELECT ... FROM cte1)），但整个查询需在 SELECT 子句内；
若启用 enable_insert_strict = true（默认），数据格式错误会导致整个插入失败。‌‌

示例：

复制代码

INSERT INTO target_tbl WITH LABEL 'my_cte_label' WITH tmp AS (SELECT id, name FROM source_tbl WHERE status = 'active') SELECT id, UPPER(name) FROM tmp; ```‌‌:ml-citation{ref="11,12" appearance="aggregated" data="citationList"} 如遇语法错误，可改用子查询包裹 CTE： ```sql INSERT INTO target_tbl SELECT * FROM ( WITH cte AS (SELECT ... FROM ...) SELECT ... FROM cte ) AS sub;

sql

INSERT INTO target_tbl WITH LABEL 'my_cte_label' WITH tmp AS (SELECT id, name FROM source_tbl WHERE status = 'active') SELECT id, UPPER(name) FROM tmp; ```‌‌:ml-citation{ref="11,12" appearance="aggregated" data="citationList"}

如遇语法错误，可改用子查询包裹 CTE： ```sql INSERT INTO target_tbl SELECT * FROM ( WITH cte AS (SELECT ... FROM ...) SELECT ... FROM cte ) AS sub;

Doris 2.0+ 对 CTE 在 DML 中的支持更稳定，旧版本（如 1.x）可能存在限制，建议升级或测试验证。

具体案例:

sql 复制代码

    with crossSet as (SELECT
    t.time  as time,
