Question

我以前没有使用过SQLite并且无法弄清楚语法，如果有帮助，我会在SQL Server中使用它。

我需要将结果放入临时表中，以便重用它们。

// SQL Server

WITH FT_CTE AS
(
SELECT pID, cID FROM brFTNode_Children 
WHERE pID = 1
UNION ALL
    SELECT e.pID, e.cID FROM brFTNode_Children e
    INNER JOIN FT_CTE ftCTE on (ftCTE.cID = e.pID)
)
SELECT * INTO #ParentChild FROM FT_CTE;

// SQLite尝试

WITH FT_CTE AS
(
SELECT pID, cID FROM brFTNode_Children 
WHERE pID = 1
UNION ALL
    SELECT e.pID, e.cID FROM brFTNode_Children e
    INNER JOIN FT_CTE ftCTE on (ftCTE.cID = e.pID)
)
CREATE TEMPORARY TABLE ParentChild as SELECT * FROM FT_CTE;

我得到Error near "CREATE": syntax error

Answer 1

CREATE TABLE statement不允许使用CTE，但SELECT会执行：

CREATE TEMPORARY TABLE ParentChild AS
WITH FT_CTE AS (
    SELECT pID, cID FROM brFTNode_Children 
    WHERE pID = 1
    UNION ALL
    SELECT e.pID, e.cID FROM brFTNode_Children e
    INNER JOIN FT_CTE ftCTE ON (ftCTE.cID = e.pID)
)
SELECT * FROM FT_CTE;

SQLITE查询结果到临时表
