Snap type:

Read

Description:

This Snap executes a SQL update with the given properties. Keys from the document will be used as the columns to update and their values will be the updated value in the column.

Note
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.

Prerequisites:

None

Support and limitations: Works in Ultra Task Pipelines.

Account:

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See Configuring PostgreSQL Accounts for information on setting up this type of account.

Views:

Input

This Snap allows exactly one input view.

Output

This Snap has no output views.

Error

This Snap has at most one error view and produces zero or more documents in the view.

Note
Database Write Snaps output all records of a batch (as configured in your account settings) to the error view if the write fails during batch processing.

Settings

Label

Required.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

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.

Example: myschema

Default value: [None]

Table name

Required. 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.

Example: people

Default value: [None]

Update condition

Required. 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;

Info
If the Update Condition field is left blank, the condition is applied on all the records of the target table.

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.

Refer to the example to understand how to use the Update Condition.

Examples:

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+ "'"

Warning

title	Caution

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.

Default value: [None]

Number of retries

Specifies 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.

Example: 3

Default value: 0

name	retries
page	File Reader

Retry interval (seconds)

Specifies the time interval between two successive retry requests. A retry happens only when the previous attempt resulted in an exception.

Example: 10

Default value: 1
