Description

Input 

Document

  • Min: 1

  • Max: 1

  • Mapper

  • Oracle Execute

This Snap allows exactly one input view. Schema name, table name and the update condition to apply on the query.

Output

Document

  • Min: 0

  • Max: 1

  • File Writer

  • Mapper

Keys from the document will be are used as the columns to update and their values will be are the updated value values 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.

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

  • 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

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.

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. 

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

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.

Info

  1. Download and import the Pipeline into SnapLogic.

  2. Configure Snap accounts, as applicable.

  3. Provide Pipeline parameters, as applicable.
