------------------------------------
Summary: SqlNode.toString can throw
Key: CALCITE-6708
URL: https://issues.apache.org/jira/browse/CALCITE-6708
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.38.0
Reporter: Mihai Budiu
Currently SqlNode.toString() calls toSqlString, which can throw if the SQL is
incorrect.
This makes toString less useful for debugging and logging.
For example, the query `SELECT TRIM()` is parsed but cannot be converted back
to a String, because SqlTrimFunction.unparse attempts to access a null operand.
I am not sure this can be fixed easily.
