Question

Today I ran into a weird problem. I have a database in SQL Server which is filled with Linq data access layer. Now I’ve got some columns that are of datatype CHAR(100) for example .

When I`m inserting everything seems to be working fine but when I retrieve these values there some sequence of whitespace has been added to the end of each value.

Anyone got an idea?

Answer 1

That is expected behavior. char [(n)] is a:

Fixed-length, non-Unicode string data. n defines the string length and must be a value from 1 through 8,000. The storage size is n bytes. The ISO synonym for char is character.

Perhaps you mean to use varchar [(n | max)] ?

Variable-length, non-Unicode string data. n defines the string length
and can be a value from 1 through 8,000. max indicates that the
maximum storage size is 2^31-1 bytes (2 GB). The storage size is the
actual length of the data entered + 2 bytes. The ISO synonyms for
varchar are char varying or character varying.
