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

ClickHouse query

2

SQLite query

What it changed

  • current timestampCURRENT_TIMESTAMP1 place
  • VARCHARTEXT1 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 ClickHouse to SQLite: Key Syntax Differences

Translating SQL queries between ClickHouse and SQLite involves subtle dialect differences that standard text find-and-replace often misses. Everything below is processed entirely in your browser using SQLParity.

Identifier Quoting

ClickHouse: `name`

SQLite: "name"

String Literal Escaping

ClickHouse: Quotes are doubled (''), backslash is an escape character.

SQLite: Quotes are doubled (''), backslash is literal.

Null-Safe Equality

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