Snap Views
Type | Format | Number of Views | Examples of Upstream and Downstream Snaps | Description |
---|
Input | Document | | | This Snap allows exactly one input view. |
Output | Document | | | Keys from the document will be used as the columns to update and their values will be the updated value in the column. |
Error | Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter while running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab: Stop Pipeline Execution: Stops the current pipeline execution if the Snap encounters an error. Discard Error Data and Continue: Ignores the error, discards that record, and continues with the remaining records. Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Asterisk ( * ): Indicates a mandatory field. Suggestion icon (): Indicates a list that is dynamically populated based on the configuration. Expression icon ( ): Indicates the value is an expression (if enabled) or a static value (if disabled). Learn more about Using Expressions in SnapLogic.

Field Name | Field Type | Description |
---|
Label* | String | Specify a unique name for the Snap. |
Schema name Default value: None Example: myschema | String/Expression/Suggestion | 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 will retrieve available database schemas during suggest values. Note |
---|
The values can be passed using the pipeline parameters but not the upstream parameter. |
|
Table name* Default Value: None Example: people | String/Expression/Suggestion | The name of the table to execute the update operation on. Note |
---|
The values can be passed using the pipeline parameters but not the upstream parameter. |

Update condition Default value: None Examples: Without using expressions Using expressions Note |

Caution Using expressions that join strings together to create SQL queries or conditions has a potential SQL injection risk and hence unsafe. Ensure that you understand all implications and risks involved before using concatenation of strings with '=' Expression enabled. |
| String/Expression | Condition to execute an update on. Info |
---|
In certain scenarios where you want to use specific data from the upstream Snaps, and do not want to change that data in the Update Snap, then you need to place the data in the original structure of the input document. Hence, we recommend that you use the format for Update condition and input data format as shown below: {
"valueToUpdate" : "true",
"original": {
"col1" : "KEY"
}
}
|
Note |
---|
In a scenario where the downstream Snap depends on the data processed in an Upstream Database Bulk Load Snap, use the Script Snap to add delay for the data to be available. |

|
Number of retries Default value: 0 Example: 3 | Integer/Expression | Specifies Specify the maximum number of attempts to be made to receive a response. The request is terminated if the attempts do not result in a response. Note |
---|
No macro found named "retries" on page "File Reader" in space "SD". If you're experiencing issues please see our Troubleshooting Guide. |
Retry interval (seconds) Default value: 1 Example: 10 | Integer/Expression | Specifies the time interval between two successive retry requests. A retry happens only when the previous attempt resulted in an exception. |
Snap Execution Default Value: Execute Only Example: Validate & Execute | Dropdown list | Select one of the following three modes in which the Snap executes: Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime. Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data. Disabled: Disables the Snap and all Snaps that are downstream from it.
