> @panbingkun Your PR doesn't contain any changes in *.md. Just wonder, why?
At present, the `sql-error-conditions.md` document is normal, with only one
space at the tail.
However, for example, when we add an error class and use command to
regenerate the `sql-error-conditions.md` file, it will generate an additional
two spaces at the tail in the `sql-error-conditions.md` file.
The main purpose of this PR is to fix the automated generation mechanism.
It can be reproduced through the following simple steps:
- Remove the description of any error class from the file
`sql-error-conditions.md`, for example:
<del>
### BATCH_METADATA_NOT_FOUND
[SQLSTATE:
42K03](sql-error-conditions-sqlstates.html#class-42-syntax-error-or-access-rule-violation)
Unable to find batch `<batchMetadataFile>`.
</del>
- Run the following command:
```
SPARK_GENERATE_GOLDEN_FILES=1 build/sbt \
"core/testOnly *SparkThrowableSuite -- -t \"Error classes match with
document\""
```
- Git will display differences:
