How do I get the length of a field in SQL?
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 stored in the emp_name string. Remember that this is different from the actual length you specified when creating the table, for example, emp_name VARCHAR (60).
How do I find the length of column value?
LEN() is a very useful method, it takes column name and returns the length of values stored in that column. You can also apply conditional logic using a CASE statement to do different things based upon different length e.g. you can shorten long name by appending “…” at the end of String.
