数据库 HANA 错误：无法使用参数变量

Question

我正在尝试使用下面的代码将值插入到我的临时表中。

我收到了这个错误

SAP Hana 数据库错误：不能 使用参数变量：DOCENTRY: line 8 col 35 (at pos 127) 2 0

我不知道出了什么问题， 请给一些建议 谢谢

这是代码：

CREATE PROCEDURE REP_PROC11( in docentry nvarchar(2))
AS 

totalval DECIMAL (19,6);


BEGIN
CREATE local TEMPORARY  TABLE #TempItem AS (
select
'FGA000001' as "ItemCode",
'2IN' as "WhsCode",
ifnull(
(
    select 
        "U_IM1_GR"
    from "@OFNC" where "DocEntry"  = :docentry
),0) as "Qty",
'11080302' as "Account",
'S02' as "ProfitCode",
'IN-PN' as "ProfitCode2" 
from DUMMY

union all

select
'FGA000002' as "ItemCode",
'2IN' as "WhsCode",
ifnull(
(
    select 
        U_IM2_GR 
    from "@OFNC" where "DocEntry"  = :docentry
),0) as "Qty",
'11080302' as "Account",
'S02' as "ProfitCode",
'IN-FN' as "ProfitCode2" from dummy);

SELECT X.*, (X."Qty"*:totalval)/Y."TotalQty" as "Val", :totalval as "TotalVal"
FROM #TempItem X
    LEFT JOIN (SELECT SUM(X1."Qty") as "TotalQty" FROM #TempItem X1) Y ON 1 = 1
WHERE X."Qty" > 0;

drop TABLE #TempItem;
end

Answer 1

这是 DDL 代码中 SQL 的限制 -

CREATE TEMPORARY TABLE

位。

鉴于您到目前为止的代码，您不需要使用临时变量。表，但通过使用表变量可以产生相同的结果（资源使用更少）。

Answer 2

对于下一个来的人，仍然可以通过以下两步方法来完成：

--create empty table
  
CREATE local TEMPORARY  TABLE #TempItem AS (SELECT * FROM MY_TABLE WHERE 1 < 0);

 --populate it

INSERT INTO #TempItem VALUES(SELECT * FROM MY_TABLE WHERE my_field = :my_input_param)
