sql - 你可以在 SQL 中使用 DOES NOT CONTAIN 来代替 not like 吗？

Question

我有一个名为 的表logs.lognotes，我想找到一种更快的方法来搜索备注中没有特定单词或短语的客户。我知道我可以使用“不喜欢”，但我的问题是，DOES NOT CONTAINS你可以用同样的方式替换不喜欢，就像你可以使用：

SELECT *
  FROM table
 WHERE CONTAINS (column, ‘searchword’)

Answer 1

Yes, you should be able to use NOT on any boolean expression, as mentioned in the SQL Server Docs here. And, it would look something like this:

SELECT *
  FROM table
 WHERE NOT CONTAINS (column, ‘searchword’)

To search for records that do not contain the 'searchword' in the column. And, according to

Performance of like '%Query%' vs full text search CONTAINS query

this method should be faster than using LIKE with wildcards.

Answer 2

你也可以简单地使用这个：

select * from tablename where not(columnname like '%value%')
