How Can I Select SQL Records Containing Specific Words in a Field?

Select records containing the specified word from the field

In SQL, you may need to get the rows where a specific field corresponds to a specific set of keywords.

Example requirements:

You want to retrieve all records in the MyTable table whose Column1 field contains any combination of the following words: "word1", "word2" and "word3".

Possible methods:

1. Multiple LIKE predicates:

   This method involves using a separate LIKE operator to check whether Column1 contains each word. Records matching any LIKE condition will be returned.

   <code class="language-sql">SELECT *
   FROM MyTable
   WHERE Column1 LIKE '%word1%'
      OR Column1 LIKE '%word2%'
      OR Column1 LIKE '%word3%'</code>

2. AND using LIKE predicate:

   For situations where all specified words must be present in Column1, multiple LIKE clauses can be combined using AND conditions.

   <code class="language-sql">SELECT *
   FROM MyTable
   WHERE Column1 LIKE '%word1%'
     AND Column1 LIKE '%word2%'
     AND Column1 LIKE '%word3%'</code>

3. Full text search:

   For more efficient searching, especially when working with large data sets, use the database's full-text search functionality. However, the specific syntax and implementation may vary depending on the database system.
