Field Name

Field Type

Label*

Default Value: Snowflake - Delete
Example: Load Employees

String

Specify a unique name for the Snap.

Schema Name

Default Value: N/A
Example: schema_demo

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 suggestable 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: employees_table

String/Expression

Specify the table name to execute the delete on.

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

Delete Condition (Truncates Table if emptycondition (deletes all records from table if left blank)

Default Value: N/A
Example: email = 'you@example.com'

String/Expression

Specify the SQL WHERE clause of the delete statement. The delete condition may also be passed via an upstream Snap or through the pipeline parameters.

Specify a valid WHERE clause for the delete condition. If you leave this field blank, the Snap truncates deletes all the records from the table.

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+ "'"

Note

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.
