this will help , The syntax is:
code :
[CONSTRAINT constraint_name] FOREIGN KEY (column_names) REFERENCES table_name ( referenced_column_names)`
CREATE TABLE bilhete(
  id_bilhete     int,
  estado_bilhete varchar2(12),
  id_viagem      int,
  id_cliente     int,
  PRIMARY KEY (id_bilhete),
  FOREIGN KEY (id_viagem) REFERENCES viagem (id_viagem),
  FOREIGN KEY (id_cliente) REFERENCES cliente (id_cliente)
);

it should still fix some issue SHOW CREATE TABLE works even if there are no rows.
Could you please reproduce this with a command line client or phpMyAdmin?
code :
SHOW CREATE TABLE `x-addresses`

Hope this helps Okay for answering this question I went through your demo.
Where I found couple of mistakes. Let me go through one by one.
code :
class func getPath(_ fileName: String) -> String {

         let bundlePath = Bundle.main.path(forResource: "Data", ofType: ".db")
         let destPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
         let fileManager = FileManager.default
         let fullDestPath = URL(fileURLWithPath: destPath).appendingPathComponent("Data.db")
         if fileManager.fileExists(atPath: fullDestPath.path){
            print("Database file is exist")
            print(fileManager.fileExists(atPath: bundlePath!))
         }else{
            do{
                try fileManager.copyItem(atPath: bundlePath!, toPath: fullDestPath.path)
            }catch{
                print("\n",error)
            }
         }

        print(fullDestPath.path)
        return fullDestPath.path
}

Simples way to make a []byte into a "virtual" File object in golang?

To fix the issue you can do There is no ready solution for this in the standard library, but it's not that hard to do it yourself.
What we need is this http.File interface:
code :
type File interface {
        io.Closer
        io.Reader
        io.Seeker
        Readdir(count int) ([]os.FileInfo, error)
        Stat() (os.FileInfo, error)
}
type myFileInfo struct {
    name string
    data []byte
}

func (mif myFileInfo) Name() string       { return mif.name }
func (mif myFileInfo) Size() int64        { return int64(len(mif.data)) }
func (mif myFileInfo) Mode() os.FileMode  { return 0444 }        // Read for all
func (mif myFileInfo) ModTime() time.Time { return time.Time{} } // Return anything
func (mif myFileInfo) IsDir() bool        { return false }
func (mif myFileInfo) Sys() interface{}   { return nil }
type MyFile struct {
    *bytes.Reader
    mif myFileInfo
}

func (mf *MyFile) Close() error { return nil } // Noop, nothing to do

func (mf *MyFile) Readdir(count int) ([]os.FileInfo, error) {
    return nil, nil // We are not a directory but a single file
}

func (mf *MyFile) Stat() (os.FileInfo, error) {
    return mf.mif, nil
}
data := []byte{0, 1, 2, 3}

mf := &MyFile{
    Reader: bytes.NewReader(data),
    mif: myFileInfo{
        name: "somename.txt",
        data: data,
    },
}

var f http.File = mf
_ = f

Where do I start to create a "Contact Info" page/table?

To fix the issue you can do My guess is that the green image and the three buttons on top (call, email, visit website) are all subviews of the table's header view. You can easily do that, if you go to Interface Builder and drag a UIView to the top part of your UITableView. Then, you will need custom cells for the next part of the interface. One easy way is to make them all in IB and then create outlets and hook them to your table. Read the Table View Programming Guide for iOS regarding more alternatives for custom cells. If you need more customization, start from this excellent article. Finally, regarding the bluish rounded background of number "20", have a look at this SO question. Good luck!
