Mihai Budiu created CALCITE-7230:
------------------------------------
Summary: Compiler rejects comparisons between NULL and a ROW value
Key: CALCITE-7230
URL: https://issues.apache.org/jira/browse/CALCITE-7230
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.40.0
Reporter: Mihai Budiu
Assignee: Mihai Budiu
Fix For: 1.41.0
This is exhibited by the following SqlValidatorTest:
{code:java}
sql("SELECT COALESCE(NULL, ROW(1))")
.withValidatorConfig(c -> c.withCallRewrite(false))
.type("RecordType(RecordType(INTEGER EXPR$0) EXPR$0) NOT NULL");
{code}
The program is rejected with:
>From line 1, column 8 to line 1, column 29: Parameters must be of the same type
The sad thing is that I already fixed a similar issue in [CALCITE-7195], but my
fix was insufficient.
