Code | Description | Severity |
|---|---|---|
The following subquery matches at least one of the patterns considered invalid and may produce compilation errors | Medium | |
The following table was GLOBAL TEMPORARY on the source code, which is not supported on the target language. | Low | |
The statement below has usages of cursor for loop | Low | |
The statement below has usages of dynamic SQL | High | |
The statement below has usages of cursor fetch bulk operations | Low | |

In this section, you could find an explanation of the severities.
Warnings for source code that there was no direct conversion to Snowflake. The code has been converted to a functionally 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.
