How to find Length of String in SQL Server? LEN() Function Example

One of the most common task while writing SQL queries or stored procedure is to find the length of String. Since most of the columns are VARCHAR, you often need to find the length before taking any action. 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. 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. SQL Server 2017.
