How do I check if a SQL Server text column is empty?

emptydatatext, notnull, sql-server, sql-server-2005, sqldatatypes

Solution

where datalength(mytextfield)=0

Problem

I am using SQL Server 2005. I have a table with a text column and I have many rows in the table where the value of this column is not null, but it is empty. Trying to compare against '' yields this response: The data types text and varchar are incompatible in the not equal to operator. Is there a special function to determine whether the value of a text column is not null but empty?
