> URL: https://issues.apache.org/jira/browse/DRILL-5639
> Project: Apache Drill
> Issue Type: Improvement
> Components: Client - JDBC
> Affects Versions: 1.10.0
> Environment: Statement is explicitly CASTING to a CHAR type with
> precision but result described as VARCHAR with maximum precision.
> select cast(C1 as CHAR(10)) from (values('ABC')) T (C1)
> select cast(C1 as VARCHAR(10)) from (values('ABC')) T (C1)
> ResultsetMetadata
> ColumnIndex getColumnName getColumnTypeName getPrecision
> getScale isNullable getTableName getSchemaName
> getCatalogName getColumnClassName getColumnDisplaySize
> getColumnLabel getColumnType isAutoIncrement isCaseSensitive isCurrency
> isDefinitelyWritable isReadOnly isSearchable isSigned

> While Drill states it internally uses VARCHAR type, unclear if Drill had
> considered/attempted to ensure it would project a CHAR(n) with blank padding.
