如何检查数据是否存在于 SQL Server 表列中，其中数据以引号重新插入

Question

I have added some data values as 'a','b','c' (same as this) in a SQL Server table column. How can I check if a or b or c is present in this table value or not?

Answer 1

Assuming that your column value looks like:

[YourColumn]
-------------
'a','b'
'a'
'a','b','c' 

The following should work:

SELECT * FROM [YourTable] WHERE Contains([YourColumn], 'a') 
OR
SELECT * FROM [YourTable] WHERE [YourColumn] LIKE '%a%'

However, unless the possible values for this column are very-very excessive, it is not recommended to store them like this in a single column. Instead, have different flag columns for each value. Again, do it only if the possible values are limited.

Hope this helps.
