--------------------------------
Summary: Special character in column names breaks JDBC statement
parsing
Key: FLINK-24948
URL: https://issues.apache.org/jira/browse/FLINK-24948
Project: Flink
Issue Type: Bug
Components: Connectors / JDBC
Affects Versions: 1.12.4
Reporter: Paul Lin
Currently, JDBC connector assumes columns names respect Java identifier naming
restrictions, but Databases that support JDBC may have different naming
restrictions. For example, MySQL allows dots and colons in column names. In
that case, JDBC connector would have trouble parsing the SQL.
We could fix this by validating field names in `JdbcDmlOptions`. In addition,
it'd be good to clarify the naming restrictions of Flink SQL, so users and
connector developers would know the standard.
