SQL converter
Rewrite quoting, escaping, row limits and function names between 16 dialects, with a list of what it refused to guess at.
Amazon Athena / Trino query
PostgreSQL query
What it changed
current timestampCURRENT_TIMESTAMP1 place
What you still need to do
Anything left in this list was recognised and left as it was on purpose. A function renamed to one that takes its arguments in a different order produces SQL that runs and returns the wrong rows, which is worse than SQL that fails.
Converting Amazon Athena / Trino to PostgreSQL: Key Syntax Differences
Translating SQL queries between Amazon Athena / Trino and PostgreSQL involves subtle dialect differences that standard text find-and-replace often misses. Everything below is processed entirely in your browser using SQLParity.
Identifier Quoting
Amazon Athena / Trino: "name"
PostgreSQL: "name"
String Literal Escaping
Amazon Athena / Trino: Quotes are doubled (''), backslash is literal.
PostgreSQL: Quotes are doubled (''), backslash is literal.
Null-Safe Equality
PostgreSQL: colA IS DISTINCT FROM colB
Why In-Browser SQL Conversion Matters
Database migrations frequently involve proprietary business logic, sensitive table schemas, and production column names. When converting SQL between Amazon Athena / Trino and PostgreSQL, SQLParity executes all parsing, tokenization, and code rewriting locally in your browser. Zero queries or schemas are transmitted to remote servers.
