TSQL - 如何查找列是否有空格char(32)？

select *
from [sometable]
where CHARINDEX(' ', [somecolumn]) > 0

不起作用？有什么想法吗？

Answer 1

你必须rtrim CHAR列。

CHAR列在右侧填充空格，直到达到最大长度。

当存储短于最大长度的字符串时，RTRIM有助于避免误报。

select * from [table] where rtrim(col) like '% %'



create table dropme
(foo char(32))

insert into dropme values('nospaces')
insert into dropme values('i have a space')
insert into dropme values('space bar')

select replace(foo,' ','|') from dropme
where foo like '% %'

nospaces
i|have|a|space
space|bar

select replace(foo,' ','|') from dropme
where rtrim(foo) like '% %'

i|have|a|space
space|bar

Answer 2

以下示例应说明如何实现此目标。

create table #tableTest
(
    someData varchar(100) not null
);

insert into #tableTest(someData) values('dsadsa');
insert into #tableTest(someData) values('fdssf 432423');
insert into #tableTest(someData) values('432423fsdv');
insert into #tableTest(someData) values('321 jhlhkj 543');



select * 
from #tableTest;

select * 
from #tableTest 
where charindex(char(32),someData) > 0;

drop table #tableTest;

Answer 3

“不起作用”是什么意思？这两种方式都适合我：

SELECT ''''+a+'''' FROM(
SELECT 'asd fgh' AS a UNION ALL
SELECT ' fgh' AS a UNION ALL
SELECT 'asd ' AS a UNION ALL
SELECT 'asfdg') As t
WHERE a LIKE '% %'

---------
'asd fgh'
' fgh'
'asd '

SELECT ''''+a+'''' FROM(
SELECT 'asd fgh' AS a UNION ALL
SELECT ' fgh' AS a UNION ALL
SELECT 'asd ' AS a UNION ALL
SELECT 'asfdg') As t
WHERE CHARINDEX(' ', a) > 0

---------
'asd fgh'
' fgh'
'asd '

Answer 4

以下对我有用：

val a: List[(Int, Int)] = dicP_SO.getOrElse(yi, List.empty[(Int, Int)] // return empty list if the key doesn't exists

Answer 5

select * from [sometable] where somecolumn like '% %'

Answer 6

鉴于你没有真正解释问题是什么......

您在寻找hardspace (nbsp)，CHAR(160)吗？还是tab CHAR(9)？这些看起来像空格但不是

Answer 7

使用以下查询：

SELECT UniqueName 
FROM employee
WHERE employeeName LIKE '% %'

Answer 8

我有和措词完全相同的问题，尽管我想看看该列是否有空格vs是否为空。这对我有用：

SELECT UniqueName 
FROM employee
WHERE ascii(employeeName) = 32

直观查询无效；下面还返回所有空行：

SELECT UniqueName 
FROM employee
WHERE employeeName = ' '
