This is a deprecated version of the SnowConvert documentation, please visit the official site .
Conversions of any large quantity of code will likely have a few errors and warnings. When using any of our tools, you can count on us to be your partner in resolving any errors you may encounter.
Below is a list of specific conversion issues for PostgreSQL that you may see when you perform a conversion with SnowConvert along with a severity level for each. Some suggested solution paths based on the severity level will follow the list of codes.
Take a minute to read through the list and the troubleshooting tips to help diagnose some of the error codes you have encountered. If you have a question that cannot be answered here, please reach out! You can drop us an email at . This is a living list, so it will grow and change as SnowConvert evolves. Updates to issue and error handling will appear on this page.

Warnings for source code that there was no direct conversion to Snowflake. The code has been converted to a functional equivalent output but should still be reviewed.
Errors that produce a functional or runtime difference. The user may have to invest a low amount of manual effort to complete the conversion.
Errors that produce a functional or runtime difference. The user may have to invest a high amount of manual effort to complete the conversion.
