How to Search for Multiple Words in an SQL Query Using LIKE?

SQL Query: Retrieve results containing any combination of specific words

Suppose you need a SQL query to select records from a table where a specific field contains multiple words and the result should contain any combination of these words.

Query:

To retrieve rows where field Column1 contains any of the specified words (regardless of their order), you can use the following query:

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

Result:

This query will return all rows containing:

• Column1 contains "word1".
• Column1 contains "word2".
• Column1 contains "word3".

Force all words to be present:

If you need all specified words to be included in the results, please modify the query as follows:

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

This will return the row where Column1 contains all three words ("word1", "word2" and "word3").

Performance Notes:

While the above queries are simple, they can be slow for large data sets. To improve performance, consider using the full-text search feature, which is optimized for searches within text fields. Exactly how full-text search is implemented depends on the specific database you are using.
