I have the following query:
update Qtable
set Q1 = ' If the alternative
hypothesis is as Ha : µ ≠µ0 ;
where QID = '856'
Q1
is of datatype nvarchar(max)
.
Now that I update in the database and see that instead of Ha : µ ≠µ0
, I get
Ha : µ ?µ0
Not sure why the update statement replaces ≠ with ? I understand its a special character but what settings should be applied to preserve the value?
You need to be sure that you prefix Unicode string literals with an N prefix. Like this:
update Qtable set Q1=' If the alternative
hypothesis is as Ha :'+ N'µ ≠µ0' ;
where QID='856'
QUERY 1: (OLD Query's String)
SELECT 'If the alternative
hypothesis is as Ha:µ ≠µ0';
OUTPUT:
If the alternative hypothesis is as Ha:µ ?µ0
QUERY 2: (NEW Query's String)
SELECT 'If the alternative
hypothesis is as Ha:' + N'µ ≠µ0';
OUTPUT:
If the alternative hypothesis is as Ha:µ ≠µ0
FOR DEMO Check the below link:
If you are not using NVARCHAR then you will get your not equal character
replaced by some other character.
Nvarchar stores UNICODE data. If you have requirements to store UNICODE or multilingual data, nvarchar is the choice. Varchar stores ASCII data and should be your data type of choice for normal use.
Use this statement:
update Qtable
set Q1 = N'If the alternative hypothesis is as Ha : µ ≠µ0'
where QID = '856'
