------------------------------------
Summary: Type inference for ARRAY_INSERT function is incorrect
Key: CALCITE-6723
URL: https://issues.apache.org/jira/browse/CALCITE-6723
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.38.0
Reporter: Mihai Budiu
The type inference is implemented in SqlLibraryOperators.arrayInsertReturnType.
This function computes the return type as a function of the types of arguments
0 and 2.
However, if argument 1 is nullable, the result type has to be nullable as well.
