             Summary: Round-tripping a DECIMAL literal through Planner -> RelToSqlConverter -> Planner throws validation error
                 Key: CALCITE-4081
                 URL: https://issues.apache.org/jira/browse/CALCITE-4081
             Project: Calcite
          Issue Type: Bug
            Reporter: Steven Talbot


Take the following SQL:
SELECT CAST('11111111111111111111111111111111.111111' AS DECIMAL(38,6)) AS "num"
And, in the default Calcite SQL dialect with all defaults, send it through Planner parse -> valiate -> rel to get a RelNode. The RelNode will have a Project with the "111111111111111.11111" literal in there as a RexLiteral with Decimal type. 

 

The use RelToSqlConverter to convert that RelNode back to SQL. The SQL now looks like 
SELECT 11111111111111111111111111111111.111111 AS "num"
 

If you attempt to parse and validate that SQL, you get "Numeric literal '11111111111111111111111111111111.111111' out of range" throw by SqlValidatorImpl.validateLiteral()
