DBeaver incorrectly gives syntax error highlighting

[ged-yuko]

@ged-yuko please create a separate issue and provide samples and other useful details there.

Snowflake documentation demonstrates expressions of the expr:something::typename form, the lack of support for which is the reason behind the behavior found by @ufuk-ergin-carbon

Here some offtopic follows:
Looks like there are also inline XPath-expressions and a FLATTEN function with a strange lambda-like arguments in Snowflake, and then there is more. These pieces doesn't really needed until you are targeting to cover all the SQL extensions provided by all the databases (or at least complete syntax of some DBs). I also don't think you would really like to implement a complete XPath handling for your semantic analysis, so another issue doesn't worth it. Otherwise it would require appropriate investigation of the SQL extensions and corresponding planning. Maybe even modular parsing, or at least modular grammars, which you apparently decided not to use at all, while different DBs have pretty different syntax extensions.

Sure. Here are the log files. Thank you for your analysis.

Hello @ufuk-ergin-carbon,

Please provide the mentioned script and the table's DDL so we can reproduce the issue. Thanks!

Hi @ShadelessFox , here is the script file. It has multiple tables. Do you need the DDL of all the joined tables?

[ShadelessFox]

Thank you for your quick answer. We will try reproducing the issue without the DDL; the query analysis probably failed due to the script's complexity, so it shouldn't depend on the schema.

Can you also provide log files? We might find something helpful there: https://github.com/dbeaver/dbeaver/wiki/Log-files#log-files

Taking a look at the parser's grammar used in dbeaver, while it parses typecast of the form expr::typename, it doesn't handle expr:something::typename. Which is also easily discoverable by observing where the identifiers stop being highlighted in this select statement. So its about the support of the json-related syntax constructs apparently.

[ShadelessFox]

@ged-yuko please create a separate issue and provide samples and other useful details there.
