01652, 00000, "unable to extend temp segment by %s in tablespace %s"

// *Cause: Failed to allocate an extent of the required number of blocks for

// a temporary segment in the tablespace indicated.

// *Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more

// files to the tablespace indicated.

 注意這裏的FACT_XX01是test所在表空間，並非temp表空間，所以這裏的ORA-1652並非是group by引起，而且在進行insert into ...  select ... 時需要在insert into的表空間中產生一個臨時段用於存儲select查詢產生的結果集，待語句執行結束後，這個臨時段會變成永久段，就是insert into的表段。會產生這種臨時段的操作還很多，例如：create index、create pk constraint、enable constraint、CATS等。 所以，要解決這個錯誤，可以整理表空間碎片，也可以爲表空間增加新的空間。
