It seems to be close to SQL server , which has some TINYINT logic in its converter - it looks like Snowflake supports this type - so you need to add this to the converter. I also see [https://docs.uipath.com/process-mining/automation-suite/2022.10/user-guide/sql-differences-between-snowflake-and-sql-server](https://docs.uipath.com/process-mining/automation-suite/2022.10/user-guide/sql-differences-between-snowflake-and-sql-server). Do any of these SQL quirks require converter changes? I notice that Snowflake SQL uses double quotes, where as Flink SQL uses back ticks , it would be worth testing that quotes work for Snowflake. -- This is an automated message from the Apache Git Service.
