osipovartem opened a new issue, #14340: URL: https://github.com/apache/datafusion/issues/14340
### Describe the bug Query ```sql create table test (COLUMN_NAME TEXT NOT NULL, constraint COLUMN_NAME_PK primary key (COLUMN_NAME)) ``` triggers the error ```Column for primary key not found in schema: COLUMN_NAME``` When creating a table, we build a schema and apply [normalization](https://github.com/apache/datafusion/blob/main/datafusion/sql/src/planner.rs#L260) to column names with to_ascii_lowercase call, which is enabled by default. But during constraint check we don't do this for the [constraint column name](https://github.com/apache/datafusion/blob/main/datafusion/sql/src/statement.rs#L1459). ### To Reproduce _No response_ ### Expected behavior The query should work without errors ```sql create table test (COLUMN_NAME TEXT NOT NULL, constraint COLUMN_NAME_PK primary key (COLUMN_NAME)) ``` ### Additional context Suggestion to use just [to_lowercase](https://github.com/apache/datafusion/blob/main/datafusion/sql/src/statement.rs#L1459) (since we don't pass column names with ascii symbols) ```rust .position(|item| *item.to_lowercase() == pk.value.to_lowercase()) ``` -- This is an automated message from the Apache Git Service.
