Field Name

Field Type

Description

Label*

Default ValueAlloyDB Delete
ExampleAlloyDB 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.

The values can be passed using the pipeline parameters but not the upstream parameter.

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 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'). Here is an example of a delete statement

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

Note

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

Here is an example of a delete statement

Number of Retries

Default Value: 0
Example3

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 ValueExecute 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.
