Steven Hawkins resolved TEIID-4608.
-----------------------------------
Resolution: Done
Changed the logic to just update the mapping prior to replacement to map to the view
columns rather than replacing by value.
Insert statement - multi-value insert into view - incorrect type
resolution if first tuple contains NULL
--------------------------------------------------------------------------------------------------------
Key: TEIID-4608
URL:
https://issues.jboss.org/browse/TEIID-4608
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 8.12.5
Reporter: Juraj DurĂ¡ni
Assignee: Steven Hawkins
Priority: Blocker
Fix For: 9.2, 9.0.6, 9.1.2
If first tuple of multi-value insert contains NULL value (regular statement, not prepared
statement), Teiid is not able to resolve types properly.
*Example 1:*
IntKey - primary key, type integer
IntNum - regular column, type integer
{code:sql}
INSERT INTO tablea (IntKey, IntNum) VALUES (1, null), (2, 2);
{code}
This query ends with ClassCastException:

If I switch tuples, no exception occurs and insert finishes successfully.
{code:sql}
INSERT INTO tablea (IntKey, IntNum) VALUES (2, 2), (1, null);
{code}
*Example 2*
IntKey - primary key, type integer
CharValue - regular column, type char
{code:sql}
INSERT INTO tablea (IntKey, CharValue) VALUES (1, null), (2, convert('+',
char));
{code}

Again, switching tuples resolves the issue.

This occurs only in case of view with defined _trigger instead of insert_. Here is my VDB
for MSSQL, but I can see same behavior for MySql and PostgreSQL
