analyzed, how many were modified, and a table indicating for each department, the total of
bonuses and whether the bonuses were modified.
Let’s now write the inline style implementation of this method. Edit the
increaseEmployeeBonuses method in
hrm.inProgress.pdqInlineStyle.HumanResourcesManager. We do not need to
use any handlers, so we use this method in Listing 12.2.
In determining how to specify the SQL stored procedure call, we need to choose how we
will specify the parameter markers. Refer to Section 5.4, which describes parameter
markers. We use variables of the type double to store the values of p_bonusFactor
and p_bonusMaxSumForDept, so we must use either the ? or the ?n type. We choose
the ? type. Because the SQL statement contains parameter markers for the OUT
parameters, we must specify corresponding parameters in the varargs parameters. They
are OUT parameters, so there is no input value. Therefore, we specify null.
Add the code in Listing 12.5 to execute the stored procedure in the inline method style:
// Execute the bonus_increase stored procedure.
storedProcedureResult = data.call ("CALL bonus_increase (?, ?, ?, ?, ?,
?)",
bonusFactor, bonusMaxSumForDepartment, null, null, null, null);
Listing 12.5 - Use an inline method to execute the stored procedure
The first thing that the application needs to do after executing the stored procedure call is
retrieve the OUT parameters from storedProcedureResult, since pureQuery will
automatically close storedProcedureResult when the last query result is retrieved.
Add the code in Listing 12.6, which retrieves the array of OUT and INOUT parameters, and
assigns the new value of the parameters to variables.
// Get the values of the OUT parameters from bonus_increase.
// Do this before getting the query results, since getting the last
// query result closes storedProcedureResult.
Object[] outputParameters = storedProcedureResult.getOutputParms ();
String departmentsWithoutNewBonuses = (String) outputParameters[2];
int countDepartmentsViewed = (Integer) outputParameters[3];
int countDepartmentsBonusChanged = (Integer) outputParameters[4];
String errorMessage = (String) outputParameters[5];
Listing 12.6 - Get the updated values of the OUT parameters from the stored
procedure
After we have retrieved the OUT parameters, we access the query result. The query result
contains a row for each employee in the company. At a large company, this could be more
data than we would want to have in memory at any point in time, so we use a
java.util.Iterator object to retrieve one row at a time from the database. Add
