永遠運行SELECT查詢

Question

我怎樣才能讓sql SELECT查詢在oracle 10g中永遠運行？它應該完成並且應該永遠運行直到停止通過殺死會話。

Answer 1

SELECT dummy 
    FROM dual 
CONNECT BY level > 0 

如果你想讓它「叉」多一點：

WITH x AS (SELECT column_value y FROM TABLE(sys.dbms_debug_vc2coll('a','b','c','d','e','f')) 
     ) 
SELECT y FROM x CONNECT BY level > 0;
