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
Generic JDBC - Update is a Write-type Snap that executes SQL UPDATE 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.

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.
Suggestion icon (): Indicates a list that is dynamically populated based on the configuration.
Expression icon (): Indicates whether the value is an expression (if enabled) or a static value (if disabled). Learn more about Using Expressions in SnapLogic.
Add icon (): Indicates that you can add fields in the field set.
Remove icon (): Indicates that you can remove fields from the field set.
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:
Without using expressions
EmpId = 12
email = 'you@example.com'
Using expressions
"EMPNO=$EMPNO and ENAME=$EMPNAME"
email = $email
emp=$emp
"emp='" + $emp + "'"
"EMPNO=" + $EMPNO + " and ENAME='" + $EMPNAME+ "'"
Using expressions that join strings together to create SQL queries or conditions has a potential SQL injection risk and is hence unsafe. Ensure that you understand all implications and risks involved before using concatenation of strings with '=' Expression enabled.
String/Expression
Specify the SQL WHERE clause of the update statement. You can define specific values or columns to update (Set condition) in the upstream Snap, such as Mapper Snap, and then use the WHERE clause to apply these conditions on the columns sourced from the upstream Snap. For instance, here is a sample of an Update SQL query: UPDATE table_name SET column1 = value1, column2 = value2, WHERE condition;
If the Update Condition field is left blank, the condition is applied on all the records of the target table.
Refer to the example to understand how to use the Update Condition.
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
Update 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.
