You may specify only one partition column. The JDBC connector supports `date`, `int`, and `enum` \ values. A null `PARTITION_BY` defaults to a single fragment. | | RANGE | Read | Required when `PARTITION_BY` is specified. The query range, \[:\]. When the partition column is an `enum` type, `RANGE` must specify a list of values, each of which forms its own fragment. If the partition column is an `int` or `date` type, `RANGE` must specify a finite left-closed range. That is, the range includes the \ but does *not* include the \. If the partition column is a `date` type, use the `yyyy-MM-dd` date format. | | INTERVAL | Read | Required when `PARTITION_BY` is specified and of the `int` or `date` type. The interval, \[:\], of one fragment. Specify the size of the fragment in \. If the partition column is a `date` type, use the \ to specify `year`, `month`, or `day`. | +| QUOTE_COLUMNS | Read | Controls whether PXF should quote column names when constructing an SQL query to the external database. Specify `true` to force PXF to quote all column names; PXF does not quote column names if any other value is provided. If `QUOTE_COLUMNS` is not specified (the default), PXF automatically quotes *all* column names in the query when *any* column name:
- includes special characters, or
- is mixed case and the external database does not support unquoted mixed case identifiers. | Example JDBC \ connection strings: -- GitLab
