------------------------------------
Hi [~hyunsik],
I examined this issue. Although the function name makes us expect something
other than {{int}}, I think that the use of {{int}} instead of
{{java.sql.Types}} here is correct.
> TajoResultSetMetaData::getColumnType should use java.sql.Types

> Components: JDBC
> Affects Versions: 0.8.0
> Reporter: Hyunsik Choi
>
> See the title.
> Currently, getColumnType method uses the following function. It returns
> invalid integer values. We should fix it.
> {code}
> public static int tajoTypeToSqlType(TajoDataTypes.DataType type) throws
> SQLException {
> switch (type.getType()) {
> case BOOLEAN:
> return Types.BOOLEAN;
> case INT1:
> return Types.TINYINT;
> case INT2:
> return Types.SMALLINT;
> case INT4:
> return Types.INTEGER;
> case INT8:
> return Types.BIGINT;
> case FLOAT4:
> return Types.FLOAT;
> case FLOAT8:
> return Types.DOUBLE;
> case NUMERIC:
> return Types.NUMERIC;
> case DATE:
> return Types.TIMESTAMP;
> case VARCHAR:
> return Types.VARCHAR;
> case TEXT:
> return Types.VARCHAR;
> default:
> throw new SQLException("Unrecognized column type: " + type);
> }
> }
> {code}
