Question

方括号有问题，我不知道错误在哪里。

DECLARE @theDate varchar(60)
DECLARE @theDay varchar(6)
DECLARE @theMonth varchar(6)
SET @theDate = GETDATE()
IF(CAST(DAY(@theDate)as int) > 9 ,SET @theDay = CAST(DAY(@theDate)as Varchar(6)), SET @theDay = '0' + CAST(DAY(@theDate)as Varchar(6)));
IF(CAST(DAY(@theDate)as int) > 9 ,SET @theMonth = CAST(MONTH(@theDate)as Varchar(6)), SET @theMonth = '0' + CAST(MONTH(@theDate)as Varchar(6)));

错误消息

Msg 102, Level 15, State 1, Line 13

Answer 1

您使用了不适当的括号以及逗号。此外，我为节定义添加了set(UA_ENABLE_AMALGAMATION ON CACHE BOOL "" FORCE) set(UA_LOGLEVEL 300) add_subdirectory(open62541) add_dependencies(${PROJECT_NAME} open62541 open62541-amalgamation-source open62541-amalgamation-header) set (${PROJECT_NAME}_SRCS ${${PROJECT_NAME}_SRCS} "${PROJECT_BINARY_DIR}/open62541/open62541.c")和begin。这是您的工作代码

end

要查看输出，请将以下行添加到您的代码中

DECLARE @theDate varchar(60)
DECLARE @theDay varchar(6)
DECLARE @theMonth varchar(6)
SET @theDate = GETDATE()
IF(CAST(DAY(@theDate)as int)) > 9 
begin  
     SET @theDay = CAST(DAY(@theDate)as Varchar(6)) 
     set @theDay = '0' + CAST(DAY(@theDate)as Varchar(6)) 
end;
IF(CAST(DAY(@theDate)as int)) > 9 
begin 
     SET @theMonth = CAST(MONTH(@theDate)as Varchar(6)) 
     SET @theMonth = '0' +    CAST(MONTH(@theDate)as Varchar(6)) 
end;

Answer 2

DECLARE @theDate varchar(60)

DECLARE @theDay varchar(6)

DECLARE @theMonth varchar(6)

SET @theDate = GETDATE()

 IF(CAST(DAY(@theDate)as int) > 9 )

  SET @theDay = CAST(DAY(@theDate)as Varchar(6))

 else

  SET @theDay = '0' +( CAST(DAY(@theDate)as Varchar(6)));

IF(CAST(DAY(@theDate)as int) > 9 )

 SET @theMonth = CAST(MONTH(@theDate)as Varchar(6))

else

 SET @theMonth = '0' + (CAST(MONTH(@theDate)as Varchar(6)));

请使用上述正确的其他语法。

Answer 3

为什么不这样做呢？

select DAY(GETDATE())
select MONTH(GETDATE())

Answer 4

也许您应该尝试此代码。

DECLARE @theDate varchar(60)
DECLARE @theDay varchar(6)
DECLARE @theMonth varchar(6)

SET @theDate = GETDATE()

IF
  CAST(DAY(@theDate)as int) > 9
THEN
  SET @theDay = CAST(DAY(@theDate)as Varchar(6))
ELSE
  SET @theDay = '0' + CAST(DAY(@theDate)as Varchar(6))
END

IF
  CAST(DAY(@theDate)as int) > 9
THEN
  SET @theMonth = CAST(MONTH(@theDate)as Varchar(6))
ELSE
  SET @theMonth = '0' + CAST(MONTH(@theDate)as Varchar(6))
END

Answer 5

在sql查询中使用if时，最好在if循环后使用Begin和End。您可以尝试一下。

IF（CAST（DAY（@theDate）as int）> 9）开始 SET @theDay = CAST（DAY（@theDate）as Varchar（6））; SET @theDay ='0'+ CAST（DAY（@theDate）as Varchar（6））; 结束 IF（CAST（DAY（@theDate）as int）> 9）开始 SET @theMonth = CAST（MONTH（@theDate）as Varchar（6））; SET @theMonth ='0'+ CAST（MONTH（@theDate）as Varchar（6））; 结束结束

Answer 6

正如其他人所说，这不是条件语句的语法。应该是：

DECLARE @theDate varchar(60)
DECLARE @theDay varchar(6)
DECLARE @theMonth varchar(6)
SET @theDate = GETDATE()

IF CAST(DAY(@theDate)as int) > 9 BEGIN
  SET @theDay = CAST(DAY(@theDate)as Varchar(6))
END
ELSE BEGIN
  SET @theDay = '0' + CAST(DAY(@theDate)as Varchar(6))
END
IF CAST(DAY(@theDate)as int) > 9 BEGIN
  SET @theMonth = CAST(MONTH(@theDate)as Varchar(6))
END
ELSE BEGIN
  SET @theMonth = '0' + CAST(MONTH(@theDate)as Varchar(6))
END

您尝试使用条件函数，您具有IIF函数，这是其语法：

DECLARE @theDate varchar(60)
DECLARE @theDay varchar(6)
DECLARE @theMonth varchar(6)
SET @theDate = GETDATE()

SET @theDay = IIF(CAST(DAY(@theDate)as int) > 9, 
                  CAST(DAY(@theDate)as Varchar(6)), 
                  '0' + CAST(DAY(@theDate)as Varchar(6)));
SET @theMonth = IIF(CAST(DAY(@theDate)as int) > 9, 
                    CAST(MONTH(@theDate)as Varchar(6)), 
                    '0' + CAST(MONTH(@theDate)as Varchar(6)));

顺便说一句，用前导零填充的最简单方法是使用格式函数：

DECLARE @theDate varchar(60)
DECLARE @theDay varchar(6)
DECLARE @theMonth varchar(6)

SET @theDate = GETDATE()
set @theDay = Format(DAY(@theDate), '00')
set @theMonth = Format(MONTH(@theDate), '00')

'，'附近的语法不正确。 AND'）'附近的语法不正确
