<p>A numeric value that is either the maximum or actual character length of a character  string or binary data type. It is the maximum character length for a fixed-length data type,  or the actual character length for a variable-length data type. Its value always excludes the  null-termination byte that ends the character string.  This information is returned from the SQL_DESC_LENGTH record field of the IRD. </p>
