SnowConvert AI - Reports

词汇表

在本部分中，我们将尝试解释 SnowConvert 生成的多个报告文档中使用的概念。

  • Lines of Code (LOC): the total number of lines in the text of the source code files, excluding blank lines, that were processed by the conversion tool. A comment is considered a line of code.

  • Parsing EWIs: the total count of parsing errors that occurred during the code analysis process. A parsing error occurs when the parser (the component that reads and understands the source code files) encounters something unexpected. This usually means a syntax error, which refers to a code element in the file that did not match the SQL grammar specification that the parser was expecting. In other cases, these errors can also occur because the parser is not yet ready to support a specific grammar. Parsing errors are considered critical issues because if the code is not parsed, SnowConvert AI cannot assess it or translate it. If this number is high in relation to the migration workload size, input code revision is advised.

  • Unrecognized Elements: any code element (or parts of them) such as DML, DDL, control statements, with parsing errors that SnowConvert AI was unable to process.

  • Lines of Code in Unrecognized Elements: the total lines of code in all the unrecognized elements. This is a good indicator of how much code SnowConvert AI was not able to process.

  • (Top-Level) Code Units: a Code Unit is the most atomic, standalone executable element. In most cases, these are statements (like DDL or DML), but they also include script files because those are executed as a single element. They are classified as top-level because they are usually the “root” elements for a database dialect, and they can contain other “smaller” definitions. The top-level code units vary from one SQL dialect to another (Oracle, Teradata, SQL Server, etc). Parsing errors might cause SnowConvert AI to not be able to properly count all top-level code units.

  • Lines of Code Conversion Rate: the percentage of lines of code that were successfully converted by SnowConvert AI into Snowflake code. Take into consideration that unrecognized elements (because of parsing issues) will affect this metric, as their source code will be counted as not converted. Furthermore, a successful element conversion might not be fully equivalent in Snowflake because of platform differences or limitations. In these cases, while the conversion rate is not punished, SnowConvert AI will generate an FDM to alert about the possible difference in functionality. A 90% conversion rate for a code unit means that only 10% of its lines of code were not converted, and therefore, EWIs are generated for them.

  • Fully Converted Code Units: the percentage of top-level code units that were fully converted without any error in any of their sub-parts. They are considered ready for deployment. Any code unit whose conversion rate is less than 100% is not counted as fully converted.

评估报告 (docx)

评估报告是一份总结代码转换率估算的文档，其中还包含许多其他实用信息，可帮助用户评估距离实现功能等效的 Snowflake 代码还有多远。

顶级代码单元报告

顶级代码单元报告概述了源代码中存在的主要对象。这些顶级对象包含有关转换状态的实用信息，可用于决定转换后的后续步骤。

问题报告

问题报告是一个文件，其中包含有关迁移过程中发生的所有问题的信息。

元素报告

元素报告显示了迁移过程中找到的语法元素的汇总计数。汇总是在多列的基础上完成，因此，如果相同的语法元素属于不同的上下文，则会有区别。例如，SELECT 查询可能是 PROCEDURE 或 VIEW 的一部分，甚至可能位于脚本文件中。使用此报告，您应该能够看到一些细微差别的元素，并查看其整体转换状态。

Functions Usage Report

The Functions Usage report summarizes the invocations of built-in and user-defined functions found during the conversion process, grouped by their migration status. This report allows the user to get details about function usages, whether they were transformed to Snowflake with no problem, or whether they require an additional post-conversion action.
