BIT type literal parsing fail?

I'm trying to execute this rather simple SELECT statement:

SELECT a FROM "Category" t0 WHERE t0.a & b'101' = b'101' LIMIT 10

where "a" is a field type BIT, which according to GridSQL SQL Reference is supported.

I keep getting the following error:

[severe] java.sql.SQLException: ERROR: Cannot Determine The Expression For (EXPRESSION)("t0"."a" & b'101')
at com.edb.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2306)

GridSQL build: 1.1b
Excerpt from console.log:

com.edb.gridsql.parser.core.ParseException: Cannot Determine The Expression For (EXPRESSION)("t0"."a" & b'101')
at com.edb.gridsql.parser.Parser.parse(Unknown Source)

Oddly enough, if left part of the expression explicitly casted, the statement goes through:

SELECT a FROM "Category" t0 WHERE t0.a::int & 5 = 5 LIMIT 10

Unfortunately this workaround wouldn't work for me, because BIT field length is 1000 in my case

Please advice.

Thank you,

This should be fixed with this commit:

We fixed it internally already, but thank you very much -- I'm sure other people will appreciate your efforts as well
