I have a requirement to retain Oracle SQL comments made inside my Liquibase sql formatted changelogs. Thus I have the following attribute set `stripComments:false`

Such comments in my SQL formatted changelogs are typically supplied using the standard -- (hyphen hyphen) characters

```
-- DROP LINK
```

However, it appears that with Liquibase attempts to execute all comments, and in this example, the comment above. This causes my Liquibase update to fail with the following error:

```
Invalid SQL type: sqlKind = UNINITIALIZED
```

I have tried to replace all occurances of `
`

`-- comment`

with ` 
`

`/*`

`
`

`comment */`

but this also generates the same error.

 

Anyone have any

ideas?
