----------------------------------
Summary: PutDatabaseRecord should give a better message when the
table cannot be found
Key: NIFI-8535
URL: https://issues.apache.org/jira/browse/NIFI-8535
Project: Apache NiFi
Issue Type: Improvement
Reporter: Matt Burgess
Currently PutDatabaseRecord calls DatabaseMetaData.getColumns() to try and
match the columns from the specified table to the fields in the incoming
record(s). However if the table itself is not found, this method returns an
empty ResultSet, so it is not known whether the table does not exist or if it
exists with no columns.
PutDatabaseRecord should call DatabaseMetaData.getTables() if the column list
is empty, and give a more descriptive error message if the table is not found.
This can help the user determine whether there is a field/column mismatch or a
catalog/schema/table name mismatch.
