SQLParity

SQL converter

Rewrite quoting, escaping, row limits and function names between 16 dialects, with a list of what it refused to guess at.

1

Oracle query

2

PostgreSQL query

What it changed

  • current timestampCURRENT_TIMESTAMP1 place

What you still need to do

Nothing in this query is the kind of thing that translates wrongly. Still run it once before you trust it.

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 Oracle to PostgreSQL: Key Syntax Differences

Translating SQL queries between Oracle 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

Oracle: "name"

PostgreSQL: "name"

String Literal Escaping

Oracle: 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 Oracle and PostgreSQL, SQLParity executes all parsing, tokenization, and code rewriting locally in your browser. Zero queries or schemas are transmitted to remote servers.
