sql语句怎样怎样写？怎样对有汉字的字段进行统计计算？高分相送

[yyy431706]

我有一字段既有汉字又有数字
用select统计时将字段里的汉字用数字0代替，请问大家有没有办法呀？

[CrazyFor]

select sum(case when isnumeric(字段)=1 then 字段 else 0 end) from 表

那要先辨别是不是汉字啊？这个以前我在c++ builder里看到这样的贴的，你去找出来看看就知道了

[CrazyFor]

select sum(case when isnumeric(字段)=1 then 字段 else 0 end) from 表

上面位小哥说的很对：）

楼主好象不是这个意思，不过存储过程中写一个循环，再用楼上的方法就ok了

sql="SELECT month(receive.sgsj) as month,
sum(case when zrrd.fc1='未填' or zrrd.fc1='为空' then 0 else clng(zrrd.fc1) end) as fc1
FROM zrrd
INNER JOIN receive ON receive.ajbh=zrrd.ajbh
WHERE year(receive.sgsj)='"&year&"' AND receive.cjr='"&cjr&"'
group by month(receive.sgsj)"
我的代码是这样的，意思是如果字段为未填或为空，
统计时取0，
否则将其转化为数字统计。
一位大哥说access不支持case when
,请问大家有没有好的解决方法，

sql="SELECT month(receive.sgsj) as month,
sum(iif(zrrd.fc1='未填' or zrrd.fc1='为空',0,clng(zrrd.fc1)) as fc1
FROM zrrd
INNER JOIN receive ON receive.ajbh=zrrd.ajbh
WHERE year(receive.sgsj)='"&year&"' AND receive.cjr='"&cjr&"'
group by month(receive.sgsj)"

用iif代替case

[pengdali]

sql="SELECT month(receive.sgsj) as month,
sum(iif(zrrd.fc1='未填' or zrrd.fc1='为空',0,clng(zrrd.fc1)) as fc1
FROM zrrd
INNER JOIN receive ON receive.ajbh=zrrd.ajbh
WHERE year(receive.sgsj)='"&year&"' AND receive.cjr='"&cjr&"'
group by month(receive.sgsj)"

用iif代替case

[yyy431706]

SELECT month(receive.sgsj) as month,sum(iif(zrrd.fc1='未填' or zrrd.fc1='为空',0,clng(zrrd.fc1)) as fc1 FROM zrrd INNER JOIN receive ON receive.ajbh=zrrd.ajbh WHERE year(receive.sgsj)='2003' AND receive.cjr='小王' group by month(receive.sgsj)
Microsoft OLE DB Provider for ODBC Drivers 错误 '80040e14'

/work/index/fc_year.asp，行 32

还是不行呀，
pengdali(大力 V2.0) ，能不能帮我看看呀，我很急呀，马上要交工了

[yyy431706]

sql="SELECT month(receive.sgsj) as month,
sum(iif(zrrd.fc1 not in('未填','为空')),clng(zrrd.fc1),0) as fc1
FROM zrrd INNER JOIN receive ON receive.ajbh=zrrd.ajbh
WHERE year(receive.sgsj)='"&year&"' AND receive.cjr='"&cjr&"'
group by month(receive.sgsj)"

用这种方法输出的sql语句如下：
SELECT month(receive.sgsj) as month,sum(iif(zrrd.fc1 not in('未填','为空')),clng(zrrd.fc1),0) as fc1 FROM zrrd INNER JOIN receive ON receive.ajbh=zrrd.ajbh WHERE year(receive.sgsj)='2003' AND receive.cjr='小王' group by month(receive.sgsj)

报错如下：
Microsoft OLE DB Provider for ODBC Drivers 错误 '80040e14'

[Microsoft][ODBC Microsoft Access Driver] 用于函数参数的个数不对 在查询表达式 'sum(iif(zrrd.fc1 not in('未填','为空')),clng(zrrd.fc1),0)' 中。

[pengdali]

sql="SELECT month(receive.sgsj) as month,
sum(iif(zrrd.fc1 in ('未填','为空'),0,zrrd.fc1) as fc1
FROM zrrd
INNER JOIN receive ON receive.ajbh=zrrd.ajbh
WHERE year(receive.sgsj)='"&year&"' AND receive.cjr='"&cjr&"'
group by month(receive.sgsj)"

呢？

[yyy431706]

也不行，输出的sql语句：
SELECT month(receive.sgsj) as month,
sum(iif(zrrd.fc1 in ('未填','为空'),0,clng(zrrd.fc1)) as fc1 FROM zrrd
INNER JOIN receive ON receive.ajbh=zrrd.ajbh
WHERE year(receive.sgsj)='2003' AND receive.cjr='小王'
group by month(receive.sgsj)


报错如下上：
Microsoft OLE DB Provider for ODBC Drivers 错误 '80040e14'

[Microsoft][ODBC Microsoft Access Driver] 语法错误 (操作符丢失) 在查询表达式 'sum(iif(zrrd.fc1 in ('未填','为空'),0,clng(zrrd.fc1)) as fc1 FROM zrrd INNER JOIN receive ON receive.ajbh=zrrd.ajbh WHERE year(receive.sgsj)='2003' AND receive.cjr='小王' group by month(receive.sgsj)' 中。

/work/index/fc_year.asp，行 34

[yyy431706]

sql="SELECT month(receive.sgsj) as month,
sum(iif(zrrd.fc1 not in ('未填','为空'),0,1)) as fc1
FROM zrrd INNER JOIN receive ON receive.ajbh=zrrd.ajbh
WHERE year(receive.sgsj)='"&year&"' AND receive.cjr='"&cjr&"'
group by month(receive.sgsj)"
这个语句是对的，
但将iif里的1改为clng(zrrd.fc1)时会出错
输出的sql语句：
SELECT month(receive.sgsj) as month,sum(iif(zrrd.fc1 not in ('未填','为空'),0,cint(zrrd.fc1))) as fc1 FROM zrrd INNER JOIN receive ON receive.ajbh=zrrd.ajbh WHERE year(receive.sgsj)='2003' AND receive.cjr='小王' group by month(receive.sgsj)

报错：
Microsoft OLE DB Provider for ODBC Drivers 错误 '80040e07'

[Microsoft][ODBC Microsoft Access Driver] 标准表达式中数据类型不匹配。
