What data type use instead of 'ntext' data type?
I want to write a trigger for one of my tables which has an ntext datatype
field an as you know the trigger can't be written for n开发者_高级运维text datatype
.
Now I want to replace the ntext
with nvarchar
datatype. The ntext
maximum length is 2,147,483,647 character whereas nvarchar(max)
is 4000 character.
what datatype can I use instead of ntext
datatype.
Or are there any ways to write trigger for when I have ntext
datatype?
It's better to say my database is designed before with SQL 2000 and it is full of data.
You're out of luck with sql server 2000, but you can possibly chain together a bunch of nvarchar(4000) variables. Its a hack, but it may be the only option you have. I would also do an assesment of your data, and see what the largest data you actually have in that column. A lot of times, columns are made in anticipation of a large data set, but in the end it doesn't have them.
in MSDN i see this : * Important * ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.
Fixed and variable-length data types for storing large non-Unicode and Unicode character and binary data. Unicode data uses the UNICODE UCS-2 character set.
and it preferd nvarchar(MAX) , You can see details below :
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 2^31-1 bytes (2 GB). The storage size, in bytes, is two times the actual length of data entered + 2 bytes. The ISO synonyms for nvarchar are national char varying and national character varying.
