-----------------------------------
Summary: Support implicit type cast for single operand family
checker
Key: CALCITE-3331
URL: https://issues.apache.org/jira/browse/CALCITE-3331
Project: Calcite
Issue Type: Improvement
Components: core
Affects Versions: 1.20.0
Reporter: Danny Chan
Assignee: Danny Chan
Fix For: 1.22.0
When the FamilyOperandTypeChecker is used to check single operand data type,
support implicit type coercion if we can.
Now some of the sql operator override method #checkOperandTypes, and use the
SqlSingleOperandTypeChecker#checkSingleOperandType to check the operand data
type, we should support the implicit type coercion for these operators.
