Why Your AI Gets a Different Answer to the Same Database Question
Asked the same question twice and got two different lists of 'top 10 customers' or 'recent signups' — with the same data, same filters, no error. Usually a LIMIT with no ORDER BY, which Postgres and MySQL don't guarantee stays consistent.

Why Your AI Database Tool Says 'Too Many Connections'
Your AI database connector worked fine, then started failing with 'too many connections' or 'remaining connection slots are reserved' — especially on Supabase or Neon. What's actually happening, and why the fix is usually the pooler endpoint, not a bigger plan.

Why Your AI's Numbers Are Too High: The JOIN Fan-Out Problem
The query ran fine, no errors, and the total revenue or order count came back way higher than you know it should be. Almost always a JOIN multiplying rows before the SUM or COUNT runs — here's how to spot it and how to ask AI to avoid it.

Does the AI Write the SQL, or Does MCP?
When Claude or ChatGPT 'queries your database,' who actually writes the SQL? A clear breakdown of the four tools an MCP database gateway exposes — list_tables, describe_table, query_table, execute_sql — and which one is running when.

Why Your AI's SQL Fails on Columns Named order, name, or group
Your AI got the column name exactly right and the query still failed with a syntax error. The column is a reserved word — order, group, name, select — and needs quoting: double quotes in Postgres, brackets in SQL Server, backticks in MySQL.

Stop Uploading Excel to Claude for Company Numbers
Uploading spreadsheets to Claude works once — then the file is stale. For KPIs that live in your database, connect read-only MCP and ask live. What you can still export to Excel, and what not to expect.
