Thanks Andrew. With `id` syntax I am not seeing “Unhandled logical type
SqlCharType” error any more. This is great progress!
However I am still seeing an issue by querying a composite field. Below is the
schema of the array type field:
Field{name=market_transactionManagement_transactionManagers, description=,
type=ARRAY<ROW<email STRING, name STRING>>, options={{}}}
My sql query is selecting a nested field: SELECT
`market_transactionManagement_transactionManagers.email` FROM PCOLLECTION
Error:
Caused by:
org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.sql.validate.SqlValidatorException:
Column 'market_transactionManagement_transactionManagers.email' not found in
any table
So what would be the right syntax? Thanks!

SELECT CAST('CAST(id AS VARCHAR)' AS VARCHAR) FROM PCOLLECTION works for me,
but I don't think that is what you wanted. Note that ' is for string literals
and ` is for escaping names in Beam SQL's default dialect config.
Try:
SELECT `id` FROM PCOLLECTION

For the first one you have
https://issues.apache.org/jira/browse/BEAM-5251<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fissues.apache.org%2Fjira%2Fbrowse%2FBEAM-5251&data=04%7C01%7Ctaol%40zillow.com%7C2c8c6047a05842fde53008d914adce2d%7C033464830d1840e7a5883784ac50e16f%7C0%7C0%7C637563559001417793%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=C4bGHyhOjB%2Bhh2HPUAAhOKICQfTisBJ1FrE4AWah1QQ%3D&reserved=0>
For the second, I opened a new issue for you:
https://issues.apache.org/jira/browse/BEAM-12323<https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fissues.apache.org%2Fjira%2Fbrowse%2FBEAM-12323&data=04%7C01%7Ctaol%40zillow.com%7C2c8c6047a05842fde53008d914adce2d%7C033464830d1840e7a5883784ac50e16f%7C0%7C0%7C637563559001427748%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=QIRqCuy9IBCEjPWWcwmIW1TR%2BB5LjrJAMTK3VzP%2F93s%3D&reserved=0>
Your second issue is because our Avro conversion library doesn't know how to
handle fixed length strings. These normally show up in SQL when you are
outputting a constant. I'm not sure exactly how to work around it, if you can
get the output type to be a VARCHAR (instead of CHAR) this problem will go
away. You might be able to do something like 'CAST("Your String Literal" AS
VARCHAR)' , 'TRIM("Your String Literal")' or ' "Your String Literal" || "" '.

Never mind. Looks like “user” is a reserved name.

Hi Beam community,
I am seeing a weird issue by using calcite sql. I don’t understand why it’s
complaining my query is not valid. Once I removed “user AS user”, it worked
fine. Please advise. Thanks.
Exception in thread "main"
