I thought that NVARCHAR(MAX) was limited to a 4000 character limit, and VARCHAR(MAX) was 8000.
This table contains errors from multiple sources.
CREATE TABLE dbo.ErrorLog(
Id BIGINT IDENTITY(1, 1) NOT NULL,
DateTimeUtc DATETIME2(7) NOT NULL,
ServiceId UNIQUEIDENTIFIER NOT NULL,
IncidentId UNIQUEIDENTIFIER NULL,
[Message] NVARCHAR(MAX) NULL,
EventType NVARCHAR(16) NOT NULL,
PRIMARY KEY CLUSTERED(Id)
WITH(PAD_INDEX=OFF, STATISTICS_NORECOMPUTE=OFF, IGNORE_DUP_KEY=OFF, ALLOW_ROW_LOCKS=ON, ALLOW_PAGE_LOCKS=ON)ON [PRIMARY]
)ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
SELECT
MaxWidth_Message = MAX(LEN([Message]))
FROM dbo.ErrorLog
And the results are [MaxWidth_Message] = 11611
Corporate Policy Prevents me from entering the entire Error, but they are stack trace errors that start with something like this;
"System.AggregateException: One or more errors occurred. ---> System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: The specified initialization vector (IV) does not match the block size for this algorithm.

……………………………………
There are many groups line lines like the last 5 all ending with a different last line :line ###
Has anyone run into anything like this before ?
Thanks.

when you use the "max" setting, the max size is 2GB.
From BOL:
nvarchar [ ( n | max ) ]
Variable-length Unicode string data. n defines the string length and can be a value from 1 through 4,000. max indicates that the maximum storage size is 2^30-1 characters.

Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?

Budd - Thursday, July 12, 2018 2:15 PMI thought that NVARCHAR(MAX) was limited to a 4000 character limit, and VARCHAR(MAX) was 8000.
If this were true, there would be no need for MAX at all – people would just use
NVARCHAR(4000) and VARCHAR(8000).
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

Thank you. It's like a light bulb just went ON...
I do remember that now and when I read it it made no sense, but all of a sudden now. "LIGHT BULB"
