    nonprintable characters in the databse, when insert data

    I have a problem. I have a structure with many elements.
    I have an array ab[5]. I have to update database field, even array is empty, but I wan to make it NULL
    Code:
    memset(ab,"\0,sizeof(ab));
    
    or
    
    ab[0] = "\0"
    noting help, I see in the database some nonprintable characters, like:
    Code:
    ннннн
    how can I put NULL or blank?

    try
    Code:
    memset(&arr[0], 0, sizeof(arr));
    loop through it setting each element to null or 0 ,zero for int arrays
