SQL LIKE Contains Text

Find rows where a code or description contains a fragment.

What this solves

Find all submix IDs containing AK. This pattern is useful when the business question is clear but a generic tutorial is too abstract.

The rule

Wrap the fragment in % wildcards.

SELECT SM FROM Mixes WHERE SM LIKE '%AK%';

Real-work checklist

  1. Define the business key and expected grain before writing the formula, query or markup.
  2. Test the pattern on a small known sample where you can verify the answer manually.
  3. Check missing values, duplicates and data types before trusting a large result.
  4. Scale to the real file or database only after the logic is proven.

Common mistake

Case sensitivity depends on the database collation; test with your actual system.
