------------------------------
Assignee: Sean Hsuan-Yi Chu (was: Aman Sinha)
> SQL parser seems to ignore specified <fractional seconds precision>
> -------------------------------------------------------------------
>
> Key: DRILL-3225
> URL: https://issues.apache.org/jira/browse/DRILL-3225
> Project: Apache Drill
> Issue Type: Bug
> Components: SQL Parser
> Reporter: Daniel Barclay (Drill)
> Assignee: Sean Hsuan-Yi Chu
> Fix For: 1.3.0
>
>
> Drill's SQL parser and/or type processing seem to ignore the fractional
> seconds precision value specified in a <fractional seconds precision> for a
> datetime or interval type.
> In one case, a type descriptor of TIME(5) yields a RelDataType whose
> getFullTypeString() returns "TIME(0)".
> In another, a type descriptor of "INTERVAL HOUR TO SECOND(3)" yields a
> RelDataType whose getFullTypeString() returns "INTERVAL HOUR TO SECOND".
> Additionally, calling .getIntervalQualifier().getFractionalSecondPrecision(
> DrillRelDataTypeSystem.DRILL_REL_DATATYPE_SYSTEM ) yields 6 (a default
> value?) instead of 3.
> (This behavior was seen in INFORMATION_SCHEMA code listing data for a view
> created using casts with the above type descriptors.)
