Postgres/Flyway：如何在 sql 文件中包装长常量字符串？

Question

我想在我的 flyway 迁移文件中换行 SQL，工作版本如下所示：

comment on table account is
'Multiple users may be associated with the same account (think multiple login methods, like gmail + facebook, etc.) ';

如果我使用 IDEA 并在字符串中按回车键，它会生成以下内容：

comment on table account is
'Multiple users may be associated with the same account (think multiple' ||
' login methods, like gmail + facebook, etc.) ';

但是运行迁移操作给出了错误 PSQLException: ERROR: syntax error at or near "||"。

版本：Flyway 4.2，Postgres 10

Answer 1

在 SQL 中跨行拆分字符串完全没问题（没有任何连接运算符）：

comment on table account is
'Multiple users may be associated with the 
same account (think multiple login methods, 
like gmail + facebook, etc.)';

Answer 2

仅包装源代码而不是字符串内容的替代答案：

comment on table account is
'Multiple users may be associated with the same account (think multiple'
' login methods, like gmail + facebook, etc.)';
