Range joins allow you to include many more matching values and therefore rows in the join. Depending on the matches and the included columns, your resulting dataset can become very large. You should use this feature with some caution.
- Range joins apply only keys whose data types can be compared.
For example, for joins involving keys of Binary data type, you can use Equal to or Not equal to joins.
Tip: Range joins cannot be applied to Datetime data type values directly. However, if you convert the values to numeric Unix time values, you should be able to specify a range join. For more information, see UNIXTIME Function.
- Any range comparison that includes one or more string columns as keys uses the string comparison greater/less than, not the numerical comparison.
This feature may need to be enabled by a workspace administrator. See Workspace Settings Page.
After range joins have been enabled, you can specify them as part of performing any join operation.
