在SQL中,CONTAINS是一种用于全文搜索的操作符。它用于在列中搜索特定的词或短语,并返回包含这些词或短语的行。使用CONTAINS操作符时,需要指定要搜索的列和要搜索的关键词或短语。CONTAINS操作符可以与其他SQL查询操作符一起使用,例如SELECT、FROM、WHERE等等。
需要注意的是,CONTAINS操作符只能在SQL Server和Oracle数据库中使用。在MySQL和PostgreSQL中,可以使用类似的全文搜索操作符,例如MATCH AGAINST和TSQUERY。

SqlServer contains
SqlServer的CONTAINS是用于在条件语句中搜索包含指定内容的文本列的函数。其语法是CONTAINS(fullText_column, 'search contents')。通过使用CONTAINS函数,可以在SqlServer数据库中的指定列中进行全文搜索,并检索包含指定内容的记录。例如,如果我们有一个名为Titles的表,其中包含Title列,我们可以使用以下SQL语句查询包含"secret"或"computer"内容的记录:
SELECT * FROM Titles WHERE CONTAINS(Title, 'secret OR computer')。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

sql contains
SQL contains is a keyword used to search for a specific value within a database table. It is typically used in conjunction with the WHERE clause to filter the results of a query. The syntax for using the contains keyword in SQL varies depending on the specific database management system being used, but generally involves specifying the column to search and the value to look for. Some databases also support advanced search options, such as partial matches or case-insensitive searches.
