SQL Quality

Query Optimize

Make slow or expensive SQL easier to fix.

Find what's making a query slow or expensive and get specific, explainable suggestions.

Use Altimate Code to tune SQL with evidence.

The problem it solves

Data teams often know a query is slow or expensive, but identifying the cause takes experience: broad scans, non-sargable filters, SELECT *, bad joins, unnecessary sorts, or missing partition pruning.

What it does

Finds performance anti-patterns in SQL.
Suggests rewritten SQL or targeted optimization steps.
Uses schema context and execution plans when available.
Can pair optimization suggestions with equivalence checks.

When to use it

WHEN

a query is slow, expensive, or scanning too much data

BEFORE

productionizing exploratory SQL

WHEN

tuning warehouse workloads

DURING

cost reduction or performance review work

How it works

The skill reviews the SQL, gathers schema or execution context when available, identifies optimization opportunities, and explains what changed and why it helps.

Tools used

sql_optimize

Find query performance issues and suggest safer rewrites or optimization strategies.

sql_analyze

Analyze SQL for anti-patterns, performance issues, and safety risks without executing it.

sql_explain

Generate warehouse execution plans so the agent can reason about query cost and performance.

altimate_core_equivalence

Check whether two SQL queries are intended to produce equivalent results.
