> JDBC thin driver will return wrong metadata for column type when user creates
> a table with Date and Decimal type.
>
> Steps to reproduce.
> 1. Start one node and create table using this command
> create table a(a varchar, b decimal,c date, primary key(a));
> 2. Run "!desc a" to show the metadata of table a
> This results is as follows:
> TABLE_CAT
> TABLE_SCHEM PUBLIC
> TABLE_NAME A
> COLUMN_NAME A
> DATA_TYPE 12
> TYPE_NAME VARCHAR
> COLUMN_SIZE null
> BUFFER_LENGTH null
> DECIMAL_DIGITS null
> NUM_PREC_RADIX 10
> NULLABLE 1
> REMARKS
