Lost or Found Lost or Found

Oracle의 LENGTHB 같은게 없나 싶었는데 있네요.아마도 예전에는 없다가 최근 버젼부터 나오는게 아닐까 생각도 듭니다. The LEN (length) function returns the number of characters in a string expression, excluding any blanks after the last character (trailing blanks). DATALENGTH, on the other hand, returns the number of bytes used for an expression. In this recipe, I will demonstrate how to measure the number of characters and bytes in a string..
