Declare

v_U_HFB_STO Varchar(200);
v_RAW_VOL_STO Number ;
v_IO_RAW_VOL_STO Number ;

 

begin

 

select B.U_BACODE||B.U_BANAME into v_U_HFB_STO, SUM(A.RAW_VOL) into v_RAW_VOL_STO, SUM(A.IO_RAW_VOL) into  v_IO_RAW_VOL_STO from UDT_SNAPSHOT_IN_TIME_REPORT A, EXT_S_ITEM B WHERE A.REORDERPOINT<>1 AND A.LOC LIKE 'STO%' AND A.ITEM=B.ITEM GROUP BY (B.U_BACODE||B.U_BANAME);
insert into STAGING.WEEKLY_ANALYSIS_TREND_REPORT_U_HFB_STO values(v_U_HFB_STO,v_RAW_VOL_STO,v_IO_RAW_VOL_STO);

 

end;

尝试在 toad 中运行代码，但出现 [Error] Execution (9: 49) 之类的错误：ORA-06550: 第 9 行，第 49 列：PL/SQL: ORA-00934: group function is not allowed here ORA-06550：第 9 行，第 1 列： PL/SQL：忽略 SQL 语句

【解决方案1】：

您的select ... into 结构不正确；它应该有一个 into:

select B.U_BACODE||B.U_BANAME, SUM(A.RAW_VOL), SUM(A.IO_RAW_VOL)
into v_U_HFB_STO, v_RAW_VOL_STO, v_IO_RAW_VOL_STO
from UDT_SNAPSHOT_IN_TIME_REPORT A, EXT_S_ITEM B
WHERE A.REORDERPOINT<>1 AND A.LOC LIKE 'STO%' AND A.ITEM=B.ITEM
GROUP BY (B.U_BACODE||B.U_BANAME);

或使用现代连接（只是因为）：

select B.U_BACODE||B.U_BANAME, SUM(A.RAW_VOL), SUM(A.IO_RAW_VOL)
into v_U_HFB_STO, v_RAW_VOL_STO, v_IO_RAW_VOL_STO
from UDT_SNAPSHOT_IN_TIME_REPORT A
join EXT_S_ITEM B ON A.ITEM=B.ITEM
WHERE A.REORDERPOINT<>1 AND A.LOC LIKE 'STO%'
GROUP BY (B.U_BACODE||B.U_BANAME);

除非您需要其他变量，否则您可以跳过它们并直接使用insert ... select：

insert into STAGING.WEEKLY_ANALYSIS_TREND_REPORT_U_HFB_STO
select B.U_BACODE||B.U_BANAME, SUM(A.RAW_VOL), SUM(A.IO_RAW_VOL)
from UDT_SNAPSHOT_IN_TIME_REPORT A
join EXT_S_ITEM B ON A.ITEM=B.ITEM
WHERE A.REORDERPOINT<>1 AND A.LOC LIKE 'STO%'
GROUP BY (B.U_BACODE||B.U_BANAME);

当然，不用 PL/SQL 也可以做到这一点。
