Find rows whose fields contain specific words in SQL
Question:
You need a SQL query that returns all rows in a table where a specified field contains one or more words from a given list. The words can appear in the field in any order.
Solution:
To retrieve rows where a field contains any specified word, use the LIKE operator with wildcard characters:
SELECT * FROM MyTable WHERE Column1 LIKE '%word1%' OR Column1 LIKE '%word2%' OR Column1 LIKE '%word3%'
To retrieve rows where a field contains all the specified words, use the AND condition:
SELECT * FROM MyTable WHERE Column1 LIKE '%word1%' AND Column1 LIKE '%word2%' AND Column1 LIKE '%word3%'
Note:
To improve performance when searching for multiple words, consider using full-text search, which is supported by most major databases. The specific implementation of full-text search depends on the database type.
