How can you find strings containing specific words using REGEXP (for example, “cat” or “dog”)?

Finding Specific Words Using REGEXP in MySQL

In MySQL, you can use the REGEXP operator to search for strings containing specific words. The pipe | symbol allows you to match one word or another, functioning as a logical OR.

Key Points for Matching Specific Words

Alternation: Use 'word1|word2' to match either word1 or word2.
Anchors Optional: To match anywhere in the string, no anchors are needed; use ^ or $ to restrict matches to start or end of the string.
Case Sensitivity: REGEXP is case-insensitive by default for non-binary columns. Use BINARY for case-sensitive matches.
Combination with Other Patterns: You can combine with character classes, quantifiers, or grouping for more complex searches.

This approach allows searching a column for multiple possible keywords in a single query without using multiple OR conditions.

Example: Match Strings Containing 'cat' or 'dog'

Example: Match Strings Starting with 'cat' or 'dog'

Example: Match Strings Ending with 'cat' or 'dog'
