如何执行具有输出参数的存储过程

Question

This question answers about calling an Oracle stored procedure: How to execute an oracle stored procedure?

However I have a procedure which takes one IN and one OUT parameter. What should my test syntax in Oracle SQL Developer look like to define a variable, run a stored procedure, and output the result of that variable?

I'm trying this but declaring the variable gives me an error:

begin
xyz MY_TABLE.EMAIL_ADDRESS%TYPE := NULL;
myPackage.GetEmailForId('12345',xyz);
end;

Answer 1

declare
    xyz MY_TABLE.EMAIL_ADDRESS%TYPE; 
begin 
    myPackage.GetEmailForId('12345',xyz);
    dbms_output.put_line(xyz);
end;

Create a unit test.

1. Go to Tools > Unit Test > Select Current Repository and follow the prompts to set up a unit test repository.
2. Go to View > Unit Test to open the Unit Testing view.
3. Right-click on tests and choose Create test .
4. Choose the connection and then pick the procedure you want to test.
5. Specify the test name and select Create single with dummy implementation then click Next .
6. Click 'Next' (you don't need any startup).
7. Specify the values for the parameters then click Finish .
8. The test should then appear in the Unit Test view and you can right-click and select Run Test .

Oracle's documentation for unit tests is here .
