Folgen Sie den einfachen Schritten unten:
public static final String SOME_NAME = "{call schema_name.org_name_pkg.return_something(?,?)}"; // Change the schema name,packagename,and procedure name.
// Simple JDBC Connection Pooling
// Here I am passing param companyId which is IN param to stored procedure which will return me some value.
Connection conn = null;
CallableStatement stmt = null;
ResultSet rset = null;
try {
conn = DriverManager.getConnection("jdbc:mysql://hostname:port/dbname","username", "password");
stmt = conn.prepareCall(SOME_NAME);//We have declared this at the very top
stmt.setString(1, companyid);//Passing CompanyID here
stmt.registerOutParameter(2, OracleTypes.CURSOR);//Refcursor selects the row based upon query results provided in Package.
stmt.execute();
rset = (ResultSet) stmt.getObject(2);
while (rset.next()) {
String orgId=rset.getString("RPT_ORG_ID");
// When using refcursor easy to get the value just by using Column name
String orgName=rset.getString("RPT_ORG_NAME");
// Some Logic based what do you want to do with the data returned back from query
} catch (Exception e) {
LOGGER.error("Error extracting ", e);
} finally {
DBUtils.cleanUp(conn, stmt, rset);
}
// Clean and close you connection
