Unconnected SQL transformation example

You are updating employee salaries with a cost of living increase. You have a CSV file that contains employee names and IDs. You need to add each employee's salary, calculate their increase, and write the data to a new CSV file.

You have the following source data:

EMP_ID, EMP_NAME
1001, John
1002, Alice
1003, Mary
1004, Mark
1005, Stephan

You have a stored procedure called ADD_SALARY in an Oracle database that adds the employee's salary to the file and a second stored procedure called SALARY_INCREASE which calculates the salary increase. In the mapping, use two unconnected SQL transformations to call the stored procedures and two Expression transformations to call the SQL transformations.

The following image shows the mapping:

The main data flow includes a Source transformation, two Expression transformations, and a Target transformation. The mapping also includes two SQL transformations that are not connected to the data flow.

Configure the transformations in the following ways:

Source transformation: Configure the Source transformation to load the source data that you want to use.

SQL_Add_Salary transformation: Configure the first SQL transformation to call the ADD_SALARY stored procedure.; On the
SQL
tab, select the connection that contains the ADD_SALARY stored procedure and then select the stored procedure.; Select
Unconnected stored procedure
.; The stored procedure has one input field for the employee ID and returns the current salary in the output field.

SQL_Increase transformation: Configure the second SQL transformation to call the SALARY_INCREASE stored procedure.; On the
SQL
tab, select the connection that contains the SALARY_INCREASE stored procedure and then select the stored procedure.; Select
Unconnected stored procedure
.; The stored procedure has one input field for the employee name and returns the new salary in the output field.

Expression_Add_Salary transformation: Configure the first Expression transformation to call the SQL_Add_Salary transformation. Create a variable field for the input parameter and an output field to capture the output of the stored procedure.; On the
Expression
tab, add a variable field named ID and configure its value as the EMP_ID field in the source. Create an output field called salary to capture the return value of the ADD_SALARY stored procedure in the first SQL transformation. Configure the salary field to call the ADD_SALARY stored procedure with the following expression:
:SP.SQL_Add_Salary(ID, PROC_RESULT)
The expression takes the variable field ID as the input parameter of the stored procedure and returns the salary value to the SALARY output field.; The following image shows how you configure the Expression transformation:

Expression_Increase transformation: Configure the second Expression transformation to call the SQL_increase transformation. Add a variable field called CurrentSalary and configure its value as the incoming salary field. Add a output field called newSalary to capture the return value of the SALARY_INCREASE stored procedure. Configure the newSalary field to call the SALARY_INCREASE stored procedure with the following expression:
:SP.SQL_increase(CurrentSalary, PROC_RESULT)
The expression takes the variable field CurrentSalary as the input parameter of the stored procedure and returns the new salary to the newSalary output field.; The following image shows how you configure the Expression transformation:
Target transformation: Configure the Target transformation to create a target file at run time.

When you run the mapping, you get the following results:

EMP_ID, EMP_NAME, salary, newSalary
1001, John, 400, 480
1002, Alice, 500, 600
1003, Mary, 400, 480
1004, Mark, 700, 840
1005, Stephan, 600, 720
