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

Required. 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

Default value: [None]

Table name

Required. The table on which to execute the insert operation.

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

Example: emp

Default value: [None]Example: email = "customer@example.com"
Default value: [None]

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.

The WHERE clause of delete statement. Document field values can be substituted into the WHERE clause by providing the path. For example, $emp.empno would insert the field empno from the emp object into the query (empno == $emp.empno would become empno == 101 if $emp.empno evaluates to 101).

Note

This field is optional, however, the operation deletes a whole table if a proper WHERE clause is not entered.

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

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.

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+ "'"

Number of retries
