In SQL, CONTAIN is often used for full-text search functionality to retrieve text content that contains specified keywords or phrases. When using CONTAIN, it needs to be used in conjunction with the CONTAINS function and full-text index.

The grammar is as follows:

SELECT columns
FROM table
WHERE CONTAINS(column, 'keyword') > 0;

In this case, column is the name of the column to search, while keyword is the keyword or phrase to search for. The CONTAINS function will return 1 or 0, indicating whether a match was found. If there are multiple keywords, you can use AND or OR to connect multiple CONTAINS conditions for the search. It is important to note that when using CONTAIN for full-text search, a full-text index needs to be created on the corresponding column to improve search efficiency.
