hi,
mostly this error comes when your size of input is exceed.
Example I have one table and it has one column say name and size of name column is varchar(20), now i am trying to insert name in this table with length 25. at that time sql server throw this error.
So recommended that chat your input and database size.
hope this help.
Accepted 0 Hi,
The reason for this error is clear.
When you set the size to your column in the sql server table, then you need to do insert/update with the required size of the data.
Support, you have a table called register
CREATE TABLE Register
(
ID INT IDENTITY(1,1)
,Name VARCHAR(10)
)
INSERT INTO Register(Name) VALUES('AAAAABBBBBBCCCCCC')
Here the actual size of the Name column is 10 and you are trying to insert 15 chars, then you will get string binary truncated.
0 thank you sir I will try it.
