Hello,

I added a table called tsql2 into the system. When I do 'describe tsql2' i
get the following error -

./herddb-cli.sh -q "DESCRIBE tsql2"
read system property: herddb.vint.read.folded=false
read system property: herddb.vint.write.folded=false
error:java.sql.SQLException: herddb.model.StatementExecutionException: From
line 1, column 10 to line 1, column 14: Column 'TSQL2' not found in any
table

Has this functionality implemented?

Thanks,

We have never implemented DESCRIBE
so your are passing by an unknown code path.


for your new feature "SHOW CREATE" you don't have to reach Calcite.
Like what we do for "EXECUTE",
I think you don't have to pass from jSQLParser as well
I would check if the statement starts with something like SHOW CREATE ......
and then do you new code
