| **Table field**    | Specify the field name from the populated list of **Target table** columns for which you want to compare.                                                                                                                                                                                                                                                                                                                                                                                            |
| **Comparator**     | <p>Specify the comparator you want to use. Note that case-sensitive comparisons are possible, depending on your connected database and <strong>Target table</strong>.You can select one of the following comparators:</p><ul><li><code>=</code></li><li><code><></code></li><li><code><</code></li><li><code><=</code></li><li><code>></code></li><li><code>>=</code></li><li><code>LIKE</code></li><li><code>BETWEEN</code></li><li><code>IS NULL</code></li><li><code>IS NOT NULL</code></li></ul> |
| **Stream field 1** | Specify the name of the field from the incoming stream that contains the row you want to use for comparison against the **Table field** value.                                                                                                                                                                                                                                                                                                                                                       |
| **Stream field 2** | Specify the name of the field from the incoming stream that contains the row you want to use for the `BETWEEN` comparison against the **Stream field 1**.                                                                                                                                                                                                                                                                                                                                            |
| **Get fields**     | Select this button to populate **Stream field 1** and **Stream field 2** from previous steps in your transformation.                                                                                                                                                                                                                                                                                                                                                                                 |

For example, if the look up value of \`QUANTITYORDERED\` is less than or equal to the \`min\_quantityordered\`, and \`PRODUCTLINE\` values map equally, then that \`QUANTITYORDERED\` row is deleted from the \`STG\_SALES\_DATA\` table.
