Overview

You can use this Snap to execute a SQL UPDATE statement for each batch of input documents. Keys from the document are used as the columns to update and their values will be the updated value in the column.

Updates will be batched up until the account's batch size property or until the structure of the update statement changes. An UPDATE statement will change if an incoming document contains different keys than a previous document.

This Snap also supports DML (Data Manipulation Language) operations (ALTER and INSERT) when using the AWS Athena database.

Snap Type

Snowflake Update is a Write-type Snap that executes SQL SELECT statement.

Prerequisites

None.

Support for Ultra Pipelines

Works in Ultra Pipelines. However, we recommend that you not use this Snap in an Ultra Pipeline. This operation is not supported for Apache Hive databases.

Known Issues & Limitations

None.

Sequence

This Snap has exactly one document input view.

Mapper

This Snap has at most one document output view. If an output view is available, then the original document that was used to create the statement will be output with the status of the update.

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. The available options are:

Stop Pipeline Execution: Stops the current pipeline execution when the Snap encounters an error.
Discard Error Data and Continue: Ignores the error, discards that record, and continues with the rest of the 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* Default Value: Generic JDBC - Update Example: Generic JDBC - Update	String	Specify the name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.
Schema Name Default Value: N/A Example: "PUBLIC"	String/Expression	Specify the database schema name. In case it is not defined, then the suggestion for the Table Name will retrieve all tables names of all schemas. The property is suggestible and will retrieve available database schemas during suggest values. The values can be passed using the pipeline parameters but not the upstream parameter.
Table Name* Default Value: N/A Example: Employee	String/Expression	Specify the name of the table in the instance. The table name is suggestible and requires an account setting. The values can be passed using the pipeline parameters but not the upstream parameter.
Update Condition Default Value: N/A Example: Macro lookup error: excerpt "ME_DB_Snaps_Query_Examples" was not found on page "Oracle - Update" (with ID 1438908) in space "SD". If you're experiencing issues please see our Troubleshooting Guide.	String/Expression	Specify the SQL WHERE clause of the update 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 three modes in which the Snap executes. Available options are: 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.

Examples

Updating data in an SQL database

This example pipeline demonstrates how to update the data in the SQL database.

Step 1: Configure the Mapper Snap to pass the data. On validation, the Snap displays the output based on the specified input.

Step 2: Configure the Generic JDBC - Update Snap to update the “TECTONIC”.”ACTRESS1” table with the update condition. On validation, the Snap displays a confirmation message indicating that the data was successfully updated in the database.

Release	Snap Pack Version	Date	Type	Updates
November 2024	main29029	13 Nov 2024	Stable	Updated and certified against the current SnapLogic Platform release.
August 2024	438patches28541	22 Oct 2024	Latest	The JDBC Snap Pack version `438patches28052`, which removed the default bundled Oracle and Redshift drivers (JAR files), is now rolled back with `438patches28541`. Now, the drivers are bundled by default with the Oracle and Redshift Snap Packs. This rollback might cause a connectivity issue when connecting the JDBC Snaps to the Sybase database using the `jConnect` Driver. Based on your use case requirements, follow the below steps: To manually upload the custom Oracle or Redshift JDBC driver in the JDBC Database account, you must use the `438patches28052` Snap Pack version. To use the bundled Oracle and Redshift drivers, you must use the latest JDBC Snap Pack version `438patches28541`.
August 2024	438patches28052	18 Sep 2024	Latest	Fixed a connectivity issue with the Generic JDBC Snaps that resulted in an error when attempting to connect the JDBC account to a Sybase database using the `jConnect` driver. Breaking change: Your existing pipelines that use JDBC Snaps to integrate with Oracle or Redshift databases using the bundled Oracle or Redshift JDBC drivers will stop functioning with the 438patches28052. Workaround You must manually upload the Oracle or Redshift JDBC driver in the JDBC Database account to run your pipelines successfully. Download the drivers: OJDBC: Maven Repository: com.oracle.database.jdbc » ojdbc6 » 11.2.0.4 Redshift: Maven Repository: com.amazon.redshift » redshift-jdbc42 » 2.1.0.11
