[GitHub] [arrow-datafusion] alamb opened a new issue #174: Support DataType::Decimal(15, 2) in TPC-H benchmark
alamb opened a new issue #174:
URL: https://github.com/apache/arrow-datafusion/issues/174
*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-11536
Currently converting the Float64 to Decimal(15, 2) fails with:
Error: Plan("\'Int64 - Decimal(15, 2)\' can\'t be evaluated because there isn\'t a common type to coerce the types to")

@alamb this issue can be closed.
The cast/try_cast has been implemented.
We can cast float to decimal or decimal to float.
