I have the following stored procedure:
create procedure MyNumericTestProc
(
@.param1 numeric(13,2) output
)
as
begin
if (@.param1 is NULL)
begin
set @.param1 = 5.25
end
set @.param1 = @.param1 + 0.01
select @.param1
end
I call it using the MS SQL Server JDBC Driver (SP3):
public class TestMyNumericTestProc
{
public static void main(String[] args)
{
try
{
testMyNumericTestProcUsingJDBC();
}
catch (ClassNotFoundexception e)
{
}
}
public void testMyNumericTestProcUsingJDBC() throws
ClassNotFoundException
{
Class.forName("com.microsoft.jdbc.sqlserver.SQLSer verDriver");
Connection conn = null;
CallableStatement cs = null;
ResultSet rs = null;
try {
conn = DriverManager.getConnection(
"jdbc:microsoft:sqlserver://MySystem\\MySQL2000Server:MyPort;databaseName=My
Database",
"username",
"password");
cs = conn.prepareCall("{call MyNumericTestProc(?)}");
BigDecimal d = new BigDecimal("300.10");
int scale = 3;
System.out.println("Input Value = " + d.toString());
System.out.println("Input Value Scale = " + d.scale());
System.out.println("Input Parameter Scale = " + scale);
// Set a BigDecimal inout parameter and execute call
cs.setObject(1, d, Types.DECIMAL);
cs.registerOutParameter(1, Types.DECIMAL, scale);
boolean csResult = cs.execute();
// Obtain result set
rs = cs.getResultSet();
rs.next();
d = rs.getBigDecimal(1);
System.out.println("ResultSet Value = " + d.toString());
System.out.println("ResultSet Scale = " + d.scale());
// Obtain value of the output parameter as object
Object obj = cs.getObject(1);
System.out.println("Output Param Value (as Object) = " +
((BigDecimal) obj).toString());
System.out.println("Output Param Scale (as Object) = " +
((BigDecimal) obj).scale());
// Obtain value of the output parameter as BigDeciaml
d = cs.getBigDecimal(1);
System.out.println("Output Param Value (as BigDecimal) = " +
d.toString());
System.out.println("Output Param Scale (as BigDecimal) = " +
d.scale());
} catch (SQLException e) {
e.printStackTrace();
} finally {
if (cs != null) {
try { cs.close(); }
catch (SQLException e) {;}
}
if (conn != null) {
try { conn.close(); }
catch (SQLException e) {;}
}
}
}
}
The output of executing this class is as follows:
Input Value = 300.10
Input Value Scale = 2
Input Parameter Scale = 3
ResultSet Value = 30.02
ResultSet Scale = 2
Output Param Value (as Object) = 30.020
Output Param Scale (as Object) = 3
Output Param Value (as BigDecimal) = 30.020
Output Param Scale (as BigDecimal) = 3
Note that I use BigDecimal as the parameter type (which is the recommended
type fr DECIMAL and NUMERIC).
Given the stored procedure, I would have expected the value 300.11 as the
value of the output
parameter and within the result set.
It appears there is an error when the scale of the input value and the scale
specified by the output
parameter do not match, and the input parameter is a BigDecimal.
Is this a problem within the realm of the MS JDBC Driver? If it is not how
do I determine where the
error is occuring?
Try running your code against another driver. If it works, then it's
probably a MS JDBC Driver problem. And it will work.

|||I revised the code to use the JDBC/ODBC Driver and re-ran. The output was
what one would expect:
Input Value = 300.10
Input Value Scale = 2
Input Parameter Scale = 3
ResultSet Value = 300.11
ResultSet Scale = 2
Output Param Value (as Object) = 300.110
Output Param Scale (as Object) = 3
Output Param Value (as BigDecimal) = 300.110
Output Param Scale (as BigDecimal) = 3
Now that I have determined this is a problem in the SQL Server JDBC Driver,
where do I file an error/bug report so that Microsoft is aware of the issue
(and possibly an idea of when the problem may be fixed)?

Microsoft engineers read this newsgroup, so they should be able to
either direct you to such a place or create a bug report themselves.
But I wouldn't wait for the bug to be fixed; MS only releases a new
JDBC driver version with a new SP and they usually fix a very limited
number of bugs; check the changelogs of their previous versions to see
what I mean.

|||Hello Fred,
I have been able to reproduce the issue as reported. I filed a bug on it
and forwarded it to development.
Thanks,
