Datagrid,actualizar solo los datos de una columna

[moNTeZIon]

MySQL
-----------------------------------------------------------------
select if(pagado=1,'true','false') as Pagado from contrato

SQL-Server
-----------------------------------------------------------------
select iif(pagado=1,'true','false') as Pagado from contrato

Por cierto, si no rula, se puede probar con CASE WHEN, algo asi:

SELECT Pagado =
CASE pagado
WHEN 1 THEN 'true'
ELSE 'false'
END,
price AS Precio
[...]
FROM titles
WHERE price IS NOT NULL
ORDER BY pagado, price
