Divisor is equal to zero

ORA-01476: divisor is equal to zero

Why it happens

A division performed with a zero or NULL denominator (division by NULL evaluates to NULL only when handled, but a direct divide by 0 raises this).

How to fix it

Guard with CASE WHEN denom = 0 THEN NULL ELSE a / b END, wrap in NULLIF(b, 0), or validate denominators before the query runs.

A note on ORA-01476

This entry is part of a hand-curated set of ORA-, FRM-, REP- and TNS- codes that actually turn up in production Oracle estates — SQL*Plus, APEX, 19c/21c, ODP.NET apps, Oracle Forms 6i/12c and Reports included. The message text above is the canonical wording; the cause and fix are written in plain language so a developer or DBA can act without digging through pages of Oracle reference docs first.

Codes outside this list of 44 are far less common. If you hit one, the official Oracle error reference and your instance's alert or listener log remain the authoritative source.
