SQL converter
Rewrite quoting, escaping, row limits and function names between 16 dialects, with a list of what it refused to guess at.
Snowflake query
Apache Spark SQL query
What it changed
'', backslash escapes\', backslash escapes1 placecurrent timestampCURRENT_TIMESTAMP1 placeVARCHARSTRING1 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 Snowflake to Apache Spark SQL: Key Syntax Differences
Translating SQL queries between Snowflake and Apache Spark SQL involves subtle dialect differences that standard text find-and-replace often misses. Everything below is processed entirely in your browser using SQLParity.
Identifier Quoting
Snowflake: "name"
Apache Spark SQL: `name`
String Literal Escaping
Snowflake: Quotes are doubled (''), backslash is an escape character.
Apache Spark SQL: Quotes are escaped with backslash (\'), backslash is an escape character.
Null-Safe Equality
Apache Spark SQL: NOT (colA <=> 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 Snowflake and Apache Spark SQL, SQLParity executes all parsing, tokenization, and code rewriting locally in your browser. Zero queries or schemas are transmitted to remote servers.
