SQL Conversion Error

Text and numeric/date types are being converted incompatibly.

LIKELY CAUSE

Why it happens

Find the bad values before casting and use safe conversion functions when available.

SAFE FIX

What to do

Profile source data instead of assuming every row matches the intended type.

Debug in this order

  1. Reproduce the problem on the smallest sample that still fails.
  2. Inspect the exact keys, types, ranges or markup involved instead of only the displayed value.
  3. Fix the root cause, then rerun the original case and one known-good case.
  4. Document the rule if the same problem can return in recurring work.
WORKTOOLS RULE

Do not hide an unexplained data error with a cosmetic workaround. Make the input and matching logic predictable first.
