Hi Belgacem,
I understand you want to retrieve data from an Oracle REF CURSOR using MATLAB, follow these steps:
- Execute the SQL Statement: Use exec to execute the SQL statement.
- Fetch the Result Set: Use fetch to get the result set.
- Extract Data: Access and process data from the ResultSet field.
You can check the below refrence code.
% Establish connection
conn = database('your_database_name', 'your_username', 'your_password', ...
'Vendor', 'Oracle', 'AutoCommit', 'on', 'ReadOnly', 'off');
% Define SQL command
cmd = 'BEGIN :1 := EDB_DI_ADMIN.PKG_GPIS_READ.GetPredictionsForMatlab(''avg generation'',''forecast'',''li...); END;';
% Prepare and execute statement
stmt = conn.Handle.createStatement();
stmt.registerOutParameter(1, java.sql.Types.REF_CURSOR);
stmt.execute(cmd);
% Retrieve and process REF CURSOR
refCursor = stmt.getObject(1);
resultSet = refCursor.getResultSet();
metaData = resultSet.getMetaData();
numCols = metaData.getColumnCount();
% Fetch data
data = {};
while resultSet.next()
row = cell(1, numCols);
for col = 1:numCols
row{col} = resultSet.getObject(col);
end
data = [data; row];
end
% Cleanup
resultSet.close();
stmt.close();
close(conn);
% Display data
disp(data);
- Ensure MATLAB is configured for Java integration.
- Add error handling as required.
- Adjust data extraction logic based on column types.
I hope it helps!
