Settings

Label*

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 retrieves available database schemas during suggest values.

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

Example: public

Table name*

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: emp

Update condition

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.

page	Oracle - Update

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.

The maximum number of times that the process must be retried before displaying an error.

Example: 2

Default value: 0

Retry interval (seconds)

The maximum resting time in seconds between subsequent retries.
