These following options are applied to the join key columns in both sources to attempt to find matches. After the join is executed, no data in either column is changed based on these selections.
| Option | Description | ||
|---|---|---|---|
| fuzzy match | Use a fuzzy matching algorithm for key value matching.
Fuzzy matching uses the doublemetaphone algorithm for matching strings (keys). Both primary encodings of each key value must match. See DOUBLEMETAPHONEEQUALS Function. | ||
| Ignore case | Ignore case differences between the join key values for matching purposes. | ||
| Ignore special characters | Ignore all characters that are not alphanumeric, accented Latin characters, or whitespace, prior to testing for a match. | ||
| Ignore whitespace | Ignore all whitespace characters, including spaces, tabs, carriage returns, and newlines. |
