Field Name | Field Type | Description |
---|---|---|
Label* Default Value: AlloyDB Delete | String | Specify a unique name for the Snap. |
Schema Name Default Value: | String/Expression | The database schema name. Selecting a schema filters the Table name list to show only those tables within the selected schema. |
Table Name Default Value: | String/Expression | Table name to execute the delete on. The values can be passed using the pipeline parameters but not the upstream parameter. |
Delete Condition (Truncates Table if empty) Default Value: None Without using expressions
Using expressions
| String/Expression | Specify a valid WHERE clause for the delete condition. The delete condition may also be passed through an upstream Snap or through the Pipeline parameters. Here is an example of a delete statement. If you leave this field blank, the Snap truncates the table. Using expressions that join strings together to create SQL queries or conditions has a potential SQL injection risk and is therefore unsafe. Ensure that you understand all implications and risks involved before using concatenation of strings with '=' Expression enabled. |
Number of Retries Default Value: 0 | Integer/Expression | 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. |
Retry Interval (Seconds) Default value: 1 | Integer/Expression | Specify 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 | Dropdown list | Select one of the following three modes in which the Snap executes:
