如何檢測列NVARCHAR是否包含拉丁文或cyrilic字符

Question

我有「模板」表：

CREATE TABLE Template (
    ID BIGINT, -- PK 
    NAME NVARCHAR(255) 
) 

列NAME包含俄語或英語文本。如何將此列的值移至RUSSIAN_NAME和ENGLISH_NAME列取決於值名稱列值。

CREATE TABLE Template (
    ID BIGINT, -- PK 
    RUSSIAN_NAME NVARCHAR(255), 
    ENGLISH_NAME NVARCHAR(255) 
) 

Answer 1

試試這個：

我不知道俄文本的意義，從什麼地方

DECLARE @tbl TABLE (name NVARCHAR(255),plainLatin NVARCHAR(255),foreignChars NVARCHAR(100)); 
INSERT INTO @tbl(name) VALUES 
(N'abcd'),(N'слов в тексте'),(N'one more'),(N'с пробелами и без них'); 

UPDATE @tbl 
SET plainLatin=CASE WHEN PATINDEX('%[^-a-zA-Z0-9 ]%' /*add signs you want to allow*/,name)=0 THEN name END 
    ,foreignChars=CASE WHEN PATINDEX('%[^-a-zA-Z0-9 ]%' /*add signs you want to allow*/,name)>0 THEN name END 

SELECT * FROM @tbl 

結果只是複製
