Let's say I have a pl/sql like below:
final Connection c = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE", "system", "manager");
String plsql = "" +
" declare " +
" p_id varchar2(20) := null; " +
" l_rc sys_refcursor;" +
" begin " +
" p_id := ?; " +
" ? := 'input parameter was = ' || p_id;" +
" open l_rc for " +
" select 1a id, 'hello' name from dual " +
" union " +
" select 2a, 'peter' from dual; " +
" ? := l_rc;" +
" end;";
CallableStatement cs = c.prepareCall(plsql);
cs.setString(1, "12345");
cs.registerOutParameter(2, Types.VARCHAR);
cs.registerOutParameter(3, OracleTypes.CURSOR);
cs.execute();
Everything's fine here but how can I get a metadat.getColumnCount() from this?
What I would like to achive? Instead of:
ResultSet cursorResultSet = (ResultSet) cs.getObject(3);
while (cursorResultSet.next ())
{
System.out.println (cursorResultSet.getString(1) + " " + cursorResultSet.getString(2));
}
I would like to find metadata count and print all values for one record in a loop like:
//pseudo code
int x = callablestatement.metadata.count();
String myRecord='';
while (cursorResultSet.next ()){
for(int i=1; i<=x; i++){
myRecord= myRecord+ " " + cursorResultSet.getString(i);
}
}
To obtain the number of columns in the result set, you need to use
cursorResultSet.getMetaData().getColumnCount()
