![]() It doesn't need to be VARCHAR, but LEN() function accepts a text value, which means it could be CHAR, VARCHAR, NCHAR or NVARCHAR as well. So remember to use LEN() function in SQL Server to find out the length of any String stored in VARCHAR column. SHOW CHARACTER SET SET s CONVERT(MySQL String Length USING ucs2) SELECT CHARLENGTH(s). In other words, a character such as counts as a single character. Get the length of a string in bytes and in characters. A multi-byte character counts as a single character. Note: the function is based on the number of bytes. you can shorten long name by appending "." at the end of String. I n SQL language the LENGTH () function allows to calculate the length of a string. You can also apply conditional logic using a CASE statement to do different things based upon different length e.g. SELECT emp_name from Employee where LEN(emp_name) 10 and LEN(name) < 50 If you want to find out all names which are less than 10 characters than you can use LEN() function like following SQL query: LEN() function Example in SQL Server 2014 This function is also explained in detail in my favorite course Microsoft SQL for Beginners by Brewster Knowlton on Udemy, one of the best course to learn SQL Server and T-SQL from a beginners point of view. In this SQL Server tutorial, I will teach you how to use the LEN() function to find out actual length or number of character in a VARCHAR or CHAR field. ![]() ![]() To give you an example, you have a column called emp_name VARCHAR(60), which means the length of this column is 60 characters, it can hold names with maximum 60 characters long, but not all names are 60 characters long, hence you may need to find the length of actual String at times. SQL Server 2017.ītw, you should remember that this is different than the length of the actual column which you specify while creating table e.g. CHARLENGTH(), i.e., CHARACTERLENGTH() The syntax for the CHARLENGTH function is: CHARLENGTH(str) The function outputs the length of the specified str string, measured in characters. This method exists from SQL Server 2008 onwards which means you can use this function in SQL Server 2012, 2014, 2016 and latest version of Microsoft SQL Server i.e. MySQL issues a warning if the result string is illegal for the specified character set. In Java, you can find the length of String by using the length() method but how about SQL Server? How will you find the length of String in Microsoft SQL Server in general and Microsoft SQL Server 2016 in particular? Well, you can use the LEN() function to find the length of a String value in SQL Server, for example, LEN(emp_name) will give you the length of values stored in the column emp_name. Since most of the columns are VARCHAR, you often need to find the length before taking any action. One of the most common task while writing SQL queries or stored procedure is to find the length of String.
