Member Functions
dataLength 
std::size_t dataLength() const;
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.
