-------------------------------

             Summary: Enumerable DML should reject assignments that may lose 
data
                 Key: CALCITE-7627
                 URL: https://issues.apache.org/jira/browse/CALCITE-7627
             Project: Calcite
          Issue Type: Bug
            Reporter: zzwqqq
            Assignee: zzwqqq


Enumerable DML currently accepts some assignments that may lose data.
One example is assigning a longer string to a shorter VARCHAR column:

{code:sql}
CREATE TABLE dept (deptno INTEGER NOT NULL, name VARCHAR(10));

INSERT INTO dept
VALUES (30, 'Engineering');
{code}

The Enumerable/server path can insert the value now. With their default 
settings, PostgreSQL, MySQL, and Oracle reject this case:
https://onecompiler.com/postgresql/44sf3dz68
https://onecompiler.com/mysql/44sf3efz4
https://onecompiler.com/oracle/44sf3ewmh

The assignment should produce a runtime error rather than truncating or 
accepting the value.
