hi trying find rows in database (sql server) have character é in text executing following queries. select count(*) t_question patindex(n'%[\xe9]%',question) > 0; select count(*) t_question patindex(n'%[\u00e9]%',question) > 0; but found 2 problems: (a) both of them returning different number of rows , (b) returning rows not have specified character. is way constructing regular expression , comparing unicode correct? edit: the question column stored using datatype nvarchar . following query gives correct result though. select count(*) t_question question n'%é%'; why not use select count(*) t_question question n'%é%' ? nb: like and patindex not accept regular expressions. in sql server pattern syntax [\xe9] means match single character within specified set . i.e. match \ , x , e or 9 . of following strings match pattern.
