sql删除不使用à

Question

我试图删除数据库中的一行,但由于某种原因它无法正常工作.

SELECT * FROM <tablename> 
WHERE MAPPING_ID = '66' 
  AND FIELD_VALUE = 'Sanità' 
  AND PARENT_VALUE = 'ITA';

结果: 66 Sanità ITA

DELETE FROM <tablename> 
WHERE MAPPING_ID = '66' 
  AND FIELD_VALUE = 'Sanità' 
  AND PARENT_VALUE = 'ITA';

结果: 0 rows deleted.

我猜它是由于à.我已经有了SET DEFINE OFF,但仍然没有去.

有什么建议？

Answer 1

DELETE FROM <tablename> 
WHERE MAPPING_ID = '66' 
  AND FIELD_VALUE = N'Sanità' 
  AND PARENT_VALUE = 'ITA';

试试这个N用于匹配nvarchar值(Unicode)

希望这会帮助你.
