Rzutuj swój ntext na nvarchar(max) i wykonaj górne i lewe operacje. Próbka poniżej.
SELECT UPPER(LEFT(cast(Comments as nvarchar(max)),1)) +
LOWER(SUBSTRING(cast(Comments as nvarchar(max)),2,
LEN(cast(Comments as nvarchar(max)))))
FROM dbo.Template_Survey;
Poniższe powinno działać w przypadku aktualizacji.
Update dbo.Template_Survey SET Comments =
UPPER(LEFT(cast(Comments as nvarchar(max)),1)) +
LOWER(SUBSTRING(cast(Comments as nvarchar(max)),2,
LEN(cast(Comments as nvarchar(max)))));
