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.

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

Table name

 

Required. Table name to execute the delete on,

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


Example: people

Delete condition (deletes all records from table if left blank)

This is an expression property to 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 deletes all the records from the table.

Examples: 

Without using expressions

Using expressions

  • "EMPNO=$EMPNO and ENAME=$EMPNAME"

  • email = $email 

  • emp=$emp

  • "emp='" + $emp + "'"

  • "EMPNO=" + $EMPNO + " and ENAME='" + $EMPNAME+ "'"

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.
