问题描述
DECLARE @ count int ,
@ index int ,
@ EMP_ID varchar ( 50 ),
@Emp_Name varchar ( 50 ),
@ ID int
SET @ index = 0;
truncate table PercentageTable;
insert into empdetail(EMP_ID) SELECT (Emp_ID)来自 DetailedPerformanceMonthlyReport;
插入 进入 PercentageTable(EMP_ID,EMP_NAME) SELECT (Emp_ID,EMP_NAME)来自 DetailedPerformanceMonthlyReport;
while ( @ index < @EMP_ID)
BEGIN
SET @ index = @ index + 1;
INSERT INTO PercentageTable(PERCENTAGE)
(选择 CAST((现在/ CAST(totdays AS DECIMAL ( 10 , 2 )))* 100 AS DECIMAL ( 5 , 2 ) )来自 DetailedPerformanceMonthlyReport);
( SELECT EMP_NAME 来自 DetailedPerformanceMonthlyReport 其中 EMP_NAME = Emp_Name));
插入 进入 PercentageTable(EMP_NAME) SELECT (Emp_Name)来自 DetailedPerformanceMonthlyReport;
END
错误:
消息102,级别15,状态1,行16
','附近的语法不正确。
消息102,等级15,状态1,行23
')'附近的语法不正确。
消息102,等级15,状态1,行26
';'附近的语法不正确。
empdetail由两列组成 ID
, EMP_ID
百分表包含三列 EMP_ID
, EMP_NAME
, PERCENTAGE
我想将三列数据推入百分比表,但是当iam尝试执行时,只有一列正在执行,剩下的表在表中显示为NULL。
任何人都可以通过使用for循环或while循环帮助我解决问题因为我是SQL的初学者。
解决方案
DECLARE @count int, @index int, @EMP_ID varchar(50), @Emp_Name varchar(50), @ID int SET @index=0; truncate table PercentageTable; insert into empdetail(EMP_ID) SELECT (Emp_ID) from DetailedPerformanceMonthlyReport; insert into PercentageTable(EMP_ID,EMP_NAME) SELECT (Emp_ID,EMP_NAME)from DetailedPerformanceMonthlyReport; while(@index <@EMP_ID) BEGIN SET @index= @index+1; INSERT INTO PercentageTable(PERCENTAGE) (select CAST((Present/CAST(totdays AS DECIMAL(10,2)))*100 AS DECIMAL(5,2)) from DetailedPerformanceMonthlyReport); (SELECT EMP_NAME from DetailedPerformanceMonthlyReport where EMP_NAME=Emp_Name)); insert into PercentageTable(EMP_NAME) SELECT (Emp_Name) from DetailedPerformanceMonthlyReport; END
ERRORS:
Msg 102, Level 15, State 1, Line 16 Incorrect syntax near ','. Msg 102, Level 15, State 1, Line 23 Incorrect syntax near ')'. Msg 102, Level 15, State 1, Line 26 Incorrect syntax near ';'.
empdetail consists of two columns ID
, EMP_ID
percentagetable consists of three columns EMP_ID
, EMP_NAME
, PERCENTAGE
I want to push the three columns data in to percentage table but when iam trying to execute only one column is executing and remaining shows NULL in the table.
Can anyone help me to solve the problem by using for loop or while loop because iam a begineer to SQL.
