How to select according to langague in sql?

Question

I have a database that contains both Hebrew and English. Unfortunately, the man who created the Data-base did a crappy job. I need to select rows that don't contain any Hebrew in them. Does SQL/MYSQL have a way of doing that?

Answer 1

This depends a lot on the character set being used for storing the data. A guess would be that it is UTF8 encoded. UTF8 encoding has a particular characteristic that is useful for this purpose: ASCII characters (the kind we use in English) are only one byte. Hebrew characters would require more than one byte.

So, you can try this:

where char_length(col) = length(col)

If you know that the strings always begin with an alphabetic character, then something like:

where left(col1, 1) between 'a' and 'z'

might also work.

Answer 2

Hi As the the column contain both english and Hebrew the data type must be nvarchar,

In SQL SERVER I DID THIS

SELECT CASE 
    WHEN CHARINDEX('?',CONVERT(VARCHAR,'2232d@❤##'))>0 THEN 'YES' 
    ELSE 'NO' 
END

this will tell you if a value is hebrew if yes else in english.

Use Locate in place of Char Index

Please let me know if this is of any help.

I am just giving you an upper idea. If you need any further help please tell.
