我的表格中有column
,文字(字符串)如 19.5 或 7.14 ,但只有 19 < strong>或 11 。
我想将 2列 1中的文字与“。”之前的所有文字分开。和“。”之后的所有文本都是1。 。
对于字符串中不带 。的条目,该表必须在第二列中包含 00 。此外,。之后的所有数据都必须为2个字符长(填充为0)。
e.g。 19.5 必须提供column1: 19 column2: 50
; 11 必须提供 column1:11 column2:00
任何人都可以帮助我使用正确的tsql代码吗?

请尝试:
select
YourCol,
SUBSTRING(YourCol, 0, CHARINDEX('.', YourCol+'.')) Col1,
LEFT(SUBSTRING(YourCol, CHARINDEX('.', YourCol+'.')+1, 2)+'00', 2) Col2
from YourTable
或
select
YourCol,
CAST(YourCol AS INT) Col1,
RIGHT(PARSENAME(YourCol,1), 2) Col2
from
(
select
CONVERT(NUMERIC(18,2), YourCol) YourCol
from YourTable
)x
样品:
declare @tbl as table(txt nvarchar(10))
insert into @tbl values ('19.5'), ('11'), ('7.14')
select
txt,
SUBSTRING(txt, 0, CHARINDEX('.', txt+'.')) Col1,
LEFT(SUBSTRING(txt, CHARINDEX('.', txt+'.')+1, 2)+'00', 2) Col2
from @tbl
或
select
txt,
CAST(txt AS INT) Col1,
RIGHT(PARSENAME(txt,1), 2) Col2
from
(
select
CONVERT(NUMERIC(18,2), txt) txt
from @tbl
)x

select cast(cast(number as float) as int) column1,
right(cast(number as numeric(9,2)), 2) column2
from
(VALUES ('19.5'),('7.14'),('19'),('11') ) t(number)

试试这个,
Declare @InputList VARCHAR(8000), @Delimiter VARCHAR(8000);
Declare @1stvalue nvarchar(20), @2ndValue Int;
Set @InputList = '19.5';
Set @Delimiter = '.';
set @1stvalue = (select RTRIM(LTRIM(SUBSTRING(@InputList,1,CHARINDEX(@Delimiter,@InputList,0)-1))));
set @2ndValue = (Select RTRIM(LTRIM(SUBSTRING(@InputList,CHARINDEX(@Delimiter,@InputList,0)+LEN(@Delimiter),LEN(@InputList)))) )
set @2ndValue = (select case when @2ndValue < 10 then convert (varchar(10) ,convert (varchar(10),@2ndValue) + '0') else convert (varchar(10), @2ndValue) end);
SELECT @1stvalue AS Column1, @2ndValue AS Column2;
您可以将其用作功能..
