Parameter Binding

To change the data in the query, configure the query parameters and bind the query parameters to input ports in the transformation. When you bind a parameter to an input port, identify the port by name in the query. The SQL Editor encloses the port name in question marks (?). The query data changes based on the value of the data in the port.

The following queries use parameter binding:

DELETE FROM Employee WHERE Dept = ?Dept?
INSERT INTO Employee(Employee_ID, Dept) VALUES (?Employee_ID?, ?Dept?)
UPDATE Employee SET Dept = ?Dept? WHERE Employee_ID > 100

The following SQL query has query parameters that bind to the Employee_ID and Dept input ports of an SQL transformation:

SELECT Name, Address FROM Employees WHERE Employee_Num =?Employee_ID? and Dept = ?Dept?

The source might have the following rows:

Employee_ID	Dept
100	Products
123	HR
130	Accounting

The Data Integration Service generates the following query statements from the rows:

SELECT Name, Address FROM Employees WHERE Employee_ID = ‘100’ and DEPT = ‘Products’
SELECT Name, Address FROM Employees WHERE Employee_ID = ‘123’ and DEPT = ‘HR’
SELECT Name, Address FROM Employees WHERE Employee_ID = ‘130’ and DEPT = ‘Accounting’
