替换声明

Question

我正在尝试构建替换语句但我收到此错误：

替换功能需要3个参数。

关键字＆＃39;附近有＆＃39;的语法不正确。如果此语句是公用表表达式，xmlnamespaces子句或更改跟踪上下文子句，则必须以分号结束前一个语句。

SQl脚本：

     select ccc.*,
     replace(replace(replace(replace(replace(bbb.Text, 
     '[Change]',convert(varchar,CAST(coalesce(ccc.change,0) as decimal(10,2)))),
     '[CurrentAmount]','$'+convert(varchar,CAST(coalesce(ccc.currentamount,0) as money),1),
     '[Increase]',convert(varchar,CAST(coalesce(ccc.increase,0) as decimal(10,2))))+ '%',
     '[AmountIncrease]',convert(varchar,CAST(coalesce(ccc.amountincrease,0) as decimal(10,2))))+ '%',
     '[AmountDecrease]',convert(varchar,CAST(coalesce(ccc.amountdecrease,0) as decimal(10,2))))+ '%'
     ) Condition
     from CCCCheck ccc with (NOLOCK)
     inner join BBBCheck bbb with (NOLOCK)on...    

Answer 1

在括号前的最后一次替换结尾处有一个额外的逗号：

 '[AmountDecrease]',convert(varchar,CAST(coalesce(ccc.amountdecrease,0) as decimal(10,2))))+ '%',
 ) Condition

看起来你可能也在增加替换附近的中间错过了一个REPLACE：

SELECT  ccc.*
      , REPLACE(
            REPLACE(
                REPLACE(
                        REPLACE(
                                REPLACE(bbb.Text, '[Change]', CONVERT(VARCHAR, CAST(COALESCE(ccc.change, 0) AS DECIMAL(10, 2)))
                                ), '[CurrentAmount]', '$' + CONVERT(VARCHAR, CAST(COALESCE(ccc.currentamount, 0) AS MONEY), 1), '[Increase]', CONVERT(VARCHAR, CAST(COALESCE(ccc.increase, 0) AS DECIMAL(10, 2)))
                        ) + '%', '[AmountIncrease]', CONVERT(VARCHAR, CAST(COALESCE(ccc.amountincrease, 0) AS DECIMAL(10, 2)))
                ) + '%', '[AmountDecrease]', CONVERT(VARCHAR, CAST(COALESCE(ccc.amountdecrease, 0) AS DECIMAL(10, 2)))
            ) + '%'
        ) Condition
FROM    CCCCheck ccc WITH (NOLOCK)

Answer 2

这样有三个地方：)))) + '%'
将最后一个括号移到：))) + '%')

Answer 3

我有一个额外的括号，我想

 convert(varchar,
         CAST(coalesce(ccc.amountincrease,
                       0
                       ) as decimal(10,2)
             )
        ))+ '%'

最后一个括号是一个额外的括号。

它应该成为

convert(varchar,
         CAST(coalesce(ccc.amountincrease,
                       0
                       ) as decimal(10,2)
             )
        )+ '%'

Answer 4

SELECT ccc.*,
REPLACE(
    REPLACE(
        REPLACE(
            REPLACE(
                REPLACE(bbb.Text,
                '[Change]', CONVERT(varchar, CAST(COALESCE(ccc.change, 0) AS decimal(10, 2)))),
            '[CurrentAmount]', '$' + CONVERT(varchar, CAST(COALESCE(ccc.currentamount, 0) AS money), 1)),
        '[Increase]', CONVERT(varchar, CAST(COALESCE(ccc.increase, 0) AS decimal(10, 2))) + '%'),
    '[AmountIncrease]', CONVERT(varchar, CAST(COALESCE(ccc.amountincrease, 0) AS decimal(10, 2))) + '%'),
'[AmountDecrease]', CONVERT(varchar, CAST(COALESCE(ccc.amountdecrease, 0) AS decimal(10, 2))) + '%')
as Condition FROM CCCCheck ccc WITH (NOLOCK)
