[jira] [Updated] (CALCITE-5533) Unclear type name in FamilyOperandTypeChecker getAllowedSignature()
[ https://issues.apache.org/jira/browse/CALCITE-5533?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oliver Lee updated CALCITE-5533:
--------------------------------
Description:
The error message from {{getAllowedSignature()}} for {{FamilyOperandTypeChecker}} [uses the SqlTypeFamily |https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql/type/FamilyOperandTypeChecker.java#L190]instead of the actual type that is used/supplied.
For example this query using the Big Query dialect (BQ TIMESTAMP is Calcite's TIMESTAMP_WITH_LOCAL_TIME_ZONE)
{quote}SELECT TIMESTAMP_DIFF(1, TIMESTAMP "2008-12-25 15:30:00", HOUR)
{quote}
You would expect the error message in the current state to be produced using Calcite types:
{quote}Cannot apply 'TIMESTAMP_DIFF' to arguments of type 'TIMESTAMP_DIFF(<INTEGER>, <TIMESTAMP_WITH_LOCAL_TIME_ZONE(0)>, <INTERVAL HOUR>)'. Supported form(s): 'TIMESTAMP_DIFF(<TIMESTAMP_WITH_LOCAL_TIME_ZONE>, <TIMESTAMP_WITH_LOCAL_TIME_ZONE>, <ANY>)'
{quote}
However the error message is actually:
{quote}Cannot apply 'TIMESTAMP_DIFF' to arguments of type 'TIMESTAMP_DIFF(<INTEGER>, <TIMESTAMP_WITH_LOCAL_TIME_ZONE(0)>, <INTERVAL HOUR>)'. Supported form(s): 'TIMESTAMP_DIFF(<TIMESTAMP>, <TIMESTAMP>, <ANY>)'
{quote}
The [TIMESTAMP_DIFF|https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql/fun/SqlLibraryOperators.java#L811] function checks that the operands are from the [SqlTypeFamily.TIMESTAMP|https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql/type/SqlTypeFamily.java#L182] type family and the error message [uses the family name|https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql/type/FamilyOperandTypeChecker.java#L190] SqlTypeFamily.TIMESTAMP, not the SqlTypeName [SqlTypeName.TIMESTAMP_WITH_LOCAL_TIME_ZONE|https://github.com/apache/calcite/blob/main/core/src/main/java/org/apache/calcite/sql/type/SqlTypeFamily.java#L183].
