Description: | This Snap enables you to fetch data from a database by providing a table name and configuring the connection. The Snap produces the records from the database on its output view, which can then be processed by a downstream Snap.
If more powerful functionality is desired, then the Execute Snap should be used. | ||||||||||||
| Prerequisites: | N/A | ||||||||||||
| Support and limitations: | Works in Ultra Task Pipelines. | ||||||||||||
| Account: | This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See Configuring Vertica Accounts for information on setting up this type of account. | ||||||||||||

Label | Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline. | ||||||||||||
Schema name | Required. The database schema name. Selecting a schema filters the Table name list to show only those tables within the selected schema. The property is suggestible and retrieves available database schemas during suggest values. Example: public | ||||||||||||
Table name | Required. The table on which to execute the insert operation. Example: emp | ||||||||||||
Where clause | The WHERE clause of the SELECT statement. This supports document value substitution (for example, $person.firstname will be substituted with the value found in the incoming document at the path). Examples: | ||||||||||||
Order by | Enter the columns in the order in which you want them set up. The default database sort order will be used. Example: name, email | ||||||||||||
Limit offset | The starting row of the query. | ||||||||||||
Limit rows | The number of rows to return from the query. Example: 10 | ||||||||||||

| Fetch Output Fields In Schema |
Default value: Not selected | ||||||||||||
| Pass through | If selected, the input document will be passed through to the output view under the key 'original'. Default value: Selected | ||||||||||||
| Ignore empty result | If selected, no document will be written to the output view when a SELECT operation does not produce any result. If this property is not selected and the Pass through property is selected, the input document will be passed through to the output view. Default value: Not selected | ||||||||||||
| Auto commit | Select one of the options for this property to override the state of the Auto commit property on the account. The Auto commit at the Snap-level has three values: True, False, and Use account setting. The expected functionality for these modes are:
Default value: False | ||||||||||||
| Match data types | Conditional. This property applies only when the Output fields property is provided with any field value(s). If this property is selected, the Snap tries to match the output data types same as when the Output fields property is empty (SELECT * FROM ...). The output preview would be in the same format as the one when SELECT * FROM is implied and all the contents of the table are displayed. Default value: Not selected | ||||||||||||
