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.

Label*

Default Value: AlloyDB Delete
Example: AlloyDB Delete

String

Specify a unique name for the Snap.

Schema Name

Default Value: 
Example:

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: 
Example:

String/Expression

Table name to execute the delete on.

Delete Condition (Truncates Table if empty)

Default Value: None
Examples: 

Without using expressions

• email = 'you@example.com' or email = $email 

• emp=$emp

Using expressions

• "EMPNO=$EMPNO and ENAME=$EMPNAME"

• "emp='" + $emp + "'"

• "EMPNO=" + $EMPNO + " and ENAME='" + $EMPNAME+ "'"

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.
The document field values can be substituted into the WHERE clause by providing the path. For example, $person.firstname would insert the field 'firstname' from the 'person' object into the query (firstname == $person.firstname would become firstname == 'Joe' if $person.firstname evaluates to 'Joe'). 

If you leave this field blank, the Snap truncates the table.

Here is an example of a delete statement. 

Number of Retries

Default Value: 0
Example: 3

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
Example: 10

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
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.
