Data type promotion does not seem to work

See original GitHub issue

version: 3.8.4 Tried to execute (over JDBC): select sum(l_orderkey) from tpch_sf10000.lineitem

Received: net.snowflake.client.jdbc.SnowflakeSQLException: Cannot convert value in the driver from type:-5 to type:LONG, value=1799999764967164128007. at net.snowflake.client.jdbc.SnowflakeResultSetV1.getObject(SnowflakeResultSetV1.java:294)

When querying the result set metadata, got: colName = sum(L_ORDERKEY), colTpe = NUMBER, dataTpe = -5, classTpe = java.lang.Long, precision = 38, scale = 0, isNullable = 1

Seems the Long is not promoted to BigDecimal.

I can set that parameter, but through the same connection we want to issue multiple queries and don’t want to treat all columns that have a scale of 0 as decimals. Should this really be handled at the client side?

Sure, no worries. Thanks for the help.
