If the input string is empty, the LENGTH Function returns the 0. if the input string is NULL then It returns NULL Therefore, the number of characters is the same as the number of bytes for the ASCII strings in SQL Server. In MySQL, LENGTH () returns the length of the string in bytes (not the number of characters). Similarly, min(a,b) indicates to take the smaller value of "a" or "b". The function when executed calculates the total number of characters present in the expression and then returns a positive integer which equals the number of characters. For nvarchar and nchar, the length of the character string is the number of byte-pairs. XSLT string length is defined as a string function and takes a single string argument and returns an integer value representing the number of characters in the string. The scale will be set to 6 if it's greater than 6 and if the integral part is greater than 32. The conversion depends on the rules of data type precedence. The LENGTH () function returns the length of a string (in bytes). Besides the UPPER function, some database systems provide you with an additional function named UCASE which is the same as the UPPER function. In this blog post, let's learn about the error message "16205 - Invalid read length provided in OPENROWSET query.
