Question

我试图在新程序中调用我之前制作的程序。无论我尝试什么，我都会在同一条线上出错。我原来的路线是：

CALL "PAYROLLDBTEST"."ABS_GetEmployeeHistoryDetail"(:EmpID)

对此我收到错误＆＃34;函数或程序名称无效：ABS_GETEMPLOYEEHISTORYDETAILS：＆＃34;

然后我试过了 CALL＆＃34; PAYROLLDBTEST / ABS_GetEmployeeHistoryDetail＆＃34;（EmpID）在这上面我得到错误＆＃34; sql语法错误：＆＃34;附近的语法不正确（＆＃34;：＆＃34;

所以请让我知道什么是错的。

编辑：继承整个程序：

CREATE PROCEDURE "PAYROLLDBTEST".GetEmploymentHistoryFunction 
(IN EmpID integer, IN StartDate timestamp, IN EndDate timestamp,OUT RETURNVALUE   NVARCHAR) 
LANGUAGE SQLSCRIPT 
AS 

BEGIN 
SELECT *, DAYS_BETWEEN("FromDate", "ToDate") + 1 AS "DaysCount" 
 FROM (SELECT "Code", "Name", "U_LineID", "U_empID", "U_Status", 
        CASE 
            WHEN ("ToDate" < :StartDate) THEN NULL 
            WHEN ("FromDate" > :EndDate) THEN NULL 
            WHEN ("FromDate" < :StartDate AND ("ToDate" BETWEEN :StartDate AND :EndDate)) THEN :StartDate 
            WHEN ("FromDate" < :StartDate AND "ToDate" > :EndDate) THEN :StartDate 
            WHEN (("FromDate" BETWEEN :StartDate AND :EndDate) AND
             ("ToDate" BETWEEN :StartDate AND :EndDate)) THEN "FromDate" 
            WHEN (("FromDate" BETWEEN :StartDate AND :EndDate) AND "ToDate" > :EndDate) THEN "FromDate" 
            WHEN ("ToDate" IS NULL AND "FromDate" < :StartDate) THEN :StartDate 
            WHEN ("ToDate" IS NULL AND ("FromDate" BETWEEN :StartDate AND :EndDate)) THEN "FromDate" 
        END AS "FromDate", 
        CASE 
            WHEN ("ToDate" < :StartDate) THEN NULL 
            WHEN ("FromDate" > :EndDate) THEN NULL 
            WHEN ("FromDate" < :StartDate AND ("ToDate" BETWEEN :StartDate AND :EndDate)) THEN "ToDate" 
            WHEN (("FromDate" BETWEEN :StartDate AND :EndDate) AND
             ("ToDate" BETWEEN :StartDate AND :EndDate)) THEN "ToDate" 
            WHEN ("FromDate" < :StartDate AND "ToDate" > :EndDate) THEN :EndDate 
            WHEN (("FromDate" BETWEEN :StartDate AND :EndDate) AND "ToDate" > :EndDate) THEN :EndDate 
            WHEN ("ToDate" IS NULL AND "FromDate" < :StartDate) THEN :EndDate 
            WHEN ("ToDate" IS NULL AND ("FromDate" BETWEEN :StartDate AND :EndDate)) THEN :EndDate 
        END AS "ToDate", "U_Position", "U_Project", "U_Sponsorship" 
    FROM (
    --select * from ABS_GetEmployeeHistoryDetails WHERE ("EmpID" IN (:EmpID))
  --select * from "PAYROLLDBTEST"."ABS_GetEmployeeHistoryDetails" WHERE ("EmpID" IN (:EmpID))
  CALL "PAYROLLDBTEST"."ABS_GetEmployeeHistoryDetails"(:EmpID,:RETURNVALUE);

 ) InnerQuery
 ) OuterQuery
 WHERE ("FromDate" between :StartDate and :EndDate OR "ToDate" between :StartDate and    :EndDate);


END;

首先，请确保您的程序确实位于您尝试调用的架构中（在您的情况下 PAYROLLDBTEST ）。

您可以通过查看HANA Studio中的目录来检查它 - 打开目录，然后打开架构 PAYROLLDBTEST ，然后打开文件夹 Procedures 。您的程序应位于此文件夹中。如果没有，请尝试刷新此文件夹。如果该程序仍未存在，则它肯定存储在另一个模式中。

其次，请确保使用正确数量的参数调用该过程。

您提到的过程似乎只有一个参数 EmpID ，它似乎是一个输入参数。您的过程名称是 GetEmployeeHistoryDetail ，因此我假设您至少有一个输出参数作为第二个参数（以获取员工历史记录的详细信息）。如果是这种情况，你应该像这样调用这个过程（假设你在另一个过程中，并希望在标量或表变量中使用内部过程的输出）：

declare someOutputVariable bigint;
CALL "PAYROLLDBTEST"."ABS_GetEmployeeHistoryDetail" (:EmpID, :someOutputVariable);

或者你的out参数是一个表变量。 someTableVariable 也可以直接作为外部过程的输出参数：

PROCEDURE "SOMESCHEMA"."yourProcedure" (
      in someInputParameter1 NVARCHAR(255),
      in someInputParameter2 BIGINT,
      out someOutputParameter1 BIGINT,
      out yourSubProcedureOutputParameter "SOMESCHEMA"."some_tabletype") 
   LANGUAGE SQLSCRIPT
   SQL SECURITY INVOKER AS
BEGIN
    // ... (other code logic)
    CALL "PAYROLLDBTEST"."ABS_GetEmployeeHistoryDetail" (:EmpID, :yourSubProcedureOutputParameter);
END;

Answer 2

应该从_SYS_BIC模式调用过程，请尝试以下调用：

call "_SYS_BIC"."PAYROLLDBTEST/ABS_GetEmployeeHistoryDetail"(:EmpID)

Answer 3

您无法在CALL声明的FROM部分内执行SELECT。

你的程序应该是这样的：

CALL "PAYROLLDBTEST"."ABS_GetEmployeeHistoryDetails"(:EmpID,:TEMP);

SELECT fields
FROM (
  SELECT fields, case1, case2
  FROM ( SELECT * FROM :TEMP ) InnerQuery
) OuterQuery
WHERE (conditions);

无法在HANA Studio中调用过程中的过程
