【问题描述】：
我有一个带有 mysql 数据库的 spring boot gradle 项目。以前在 jooq 版本 3.13.6 下，我的 sql 被解析没有错误。当更新到更高的 jooq 版本（3.14.X 和 3.15.X）并使用 jooq 生成/解析迁移时，我得到以下输出：
严重的 DDLDatabase 错误：您的 SQL 字符串无法解析或 解释。这可能有多种原因，包括：
- jOOQ 解析器不理解您的 SQL
- jOOQ DDL 模拟逻辑（转换为 H2）无法模拟您的 SQL
org.h2.jdbc.JdbcSQLSyntaxErrorException：找不到函数“coalesce”；
下面给出了发生错误的基本 sql 示例。使用 jooq 3.13.6 解析相同的视图。
DROP VIEW IF EXISTS view1;
CREATE VIEW view1 AS
SELECT COALESCE(SUM(table1.col1), 0) AS 'sum'
FROM table1;
我现在迷路了。我在 jooq 更改日志中没有看到任何相关更改。
非常感谢任何帮助或进一步研究的指导。
扩展堆栈跟踪：
11:10:30 SEVERE DDLDatabase Error : Your SQL string could not be parsed or interpreted. This may have a variety of reasons, including:
- The jOOQ parser doesn't understand your SQL
- The jOOQ DDL simulation logic (translating to H2) cannot simulate your SQL
If you think this is a bug or a feature worth requesting, please report it here: https://github.com/jOOQ/jOOQ/issues/new/choose
As a workaround, you can use the Settings.parseIgnoreComments syntax documented here:

【问题讨论】：
-
您可以尝试在 drop view 之前添加 -- [jooq ignore start] 并在之后添加 -- [jooq ignore stop] 吗？
-
感谢您的评论。忽略视图确实有助于避免错误。然而，我希望有一个可以从视图中处理 sql 的解决方案。毕竟这适用于以前的 jooq 版本。
-
完整的堆栈跟踪和代码生成配置是什么？
-
我更新了问题并添加了stacktrace和更新到jooq版本3.15.5后的配置
-
感谢您的更新。为了完整起见，您能否在省略号 (
...) 的位置添加您省略的内容。是coalesce还是"coalesce"？如果是后者，这可能是github.com/jOOQ/jOOQ/issues/11342 的情况
