Execute external database Stored Procedure from X++ code using ODBC connectivity

This is to show a method to execute external database stored procedures from X++ code. Create a job in AOT with following code. Follow the steps as explained here in the code like replace Server Name, Database name , Stored Procedure name.

The below code is executed through the ODBC Connection.

static void execExternalDatabase(Args _args)
{
LoginProperty loginProperty;
ODBCConnection odbcConnection;
Statement statement;
ResultSet resultSet;

ResultSetMetaData resultSetMetaData;
Counter counter;
str sql;
SqlStatementExecutePermission perm;
;


loginProperty = new LoginProperty();
loginProperty.setServer("SERVERNAME Here"); // Replace your Database Server Name here
loginProperty.setDatabase("DemoDB"); //Replace your Database name here
odbcConnection = new ODBCConnection(loginProperty); // setting odbc connection here.

// ODBC Connection to create statement
statement = odbcConnection.createStatement();

// Replace the StoredProcedure you want to execute.
sql = strfmt('EXEC[myStoredProcedureName]');

// Set code access permission to Execute
perm = new SqlStatementExecutePermission(sql);
perm.assert();

try
{
// if Stored Procedure has Select query use executeQuery method.

resultSet = statement.executeQuery(sql);
resultSet.next();

resultSetMetaData = resultSet.getMetaData();
for (counter = 1; counter <= resultSetMetaData.getColumnCount(); counter++)
{
switch(resultSetMetaData.getColumnType(counter))
{
case 0,1 :
info(resultSet.getString(counter));
break;
case 3:
info(date2StrUsr(resultSet.getdate(counter)));
break;
}
}
}
catch (exception::Error)
{
print "An error occured in the query.";
pause;
}
// Code access permission scope ends here.
CodeAccessPermission::revertAssert();
}

Used a simple select query in the stored procedure and the result will be displayed on the infolog.
