SQL Server - Searching string with international characters using LIKE clause
I have a field 'Description' which can have product descriptions with any unicode characters. If I search for a description which contains an international character, with a LIKE condition (word searched with does not have the international character) I get the following results:
Ex: GEWÜRZTRAMINER is one of the descriptions. When I do:
Select * from table where Description LIKE '%GEWURZTRAMINER%', it retrieves the entry.
When I do:
Select * from table where Description LIKE '%GEWURZ%', the entry is not retrieved.
(Note: the search condition does not include the Ü but has a U)
Is there a way around this so that I can retrieve with '%GEWURZ%' as well?
For bog standard varchar, you'd have to coerce to a accent insensitive collation
Select 1 where 'GEWÜRZTRAMINER' COLLATE LATIN1_GENERAL_CI_AI LIKE '%GEWURZTRAMINER%'
There should be no difference between the calls though for the SQL you provided.
It will depend on the collation order for the column. It should work if you use e.g. SQL_Latin1_General_CP1_CI_AI
