scheme

    CREATE TABLE [dbo].[Buns]
    (
        [ID] INT NOT NULL PRIMARY KEY IDENTITY,
        
        [ENTRY] NVARCHAR(50) NULL, 
        [LEVEL] NCHAR(10) NULL,

SELECT ARABIC, JAPANESE , ENGLISH
FROM dbo.Buns
--WHERE JAPANESE = '私は良子に花をあげた。'
--WHERE ARABIC = 'أعطيت لهاناكو زهرة';
WHERE ENGLISH = 'I gave Yoshiko flowers';

appreciate your support with clear steps as am still a beginner

thanks

>Solution :

To specify an nvarchar string literal, you need to prefix it with N:

SELECT ARABIC, JAPANESE, ENGLISH
FROM dbo.Buns
WHERE ARABIC = N'قيمة للبحث عنها'
