在大数据运行时,以下查询会抛出临时空间错误(无法增加临时空间)。我认为问题在于查询的编写方式。有人可以帮助您更有效地重写查询:
UPDATE TABLE1 tab
SET tab.tgt_col = 1
WHERE tab.id1 IN (
SELECT
Id1 FROM TABLE1 t1 WHERE
t1.id1 NOT IN ( SELECT Min(id1) FROM TABLE1 t2
WHERE t2.date_col= :A
AND t1.col1 = t2.col2
AND t1.col2 =t2.col2
AND t1.col3 =t2.col3
AND t1.col4 =t2.col4
AND Nvl(t1.col5, 'XX') =Nvl(t2.col5, 'XX')
AND t1.col6 = t2.col6
AND t1.col7 = t2.col7
AND To_Char(t1.col_time,'YYYYMMDD') = To_Char(t2.col_time,'YYYYMMDD')
)
AND t1.col7 IN('a','b','c')
AND t1.date_col = :A
AND t1.COUNTRY IN ('US','CA')
AND t1.col1 IN (SELECT col1 FROM table2 F
WHERE F.col8 IN (SELECT col8 FROM table3
WHERE date_col=:A AND col9 = 1 )
AND F.col10 = '1')
)
AND tab.date_col = :A;
