What's the quickest way to convert nvarchar(max) to nvarchar(n) and indicate there's more data?
eg: convert the column Address to nvarchar(100) and if Address is larger than 100 characters then replace the last 3 characters with "..."
UPDATE t
SET t.Address = SUBSTRING(t.Address, 1, 97) + '...'
FROM TableName t
WHERE LEN(t.Address) > 100;
ALTER TABLE dbo.TableName
ALTER COLUMN Address NVARCHAR (100);
UPDATE Table
SET [Address] = CASE
WHEN LEN([Address]) > 100
THEN CAST([Address] AS NVARCHAR(97)) + N'...'
ELSE CAST([Address] AS NVARCHAR(100))
END
now change the data type of your column since all the data more than 100 characters will be truncated after the above statement.
ALTER TABLE TableName
ALTER COLUMN [Address] NVARCHAR(100)
