I need an SQL statement to capitalize the first letter of each word. The other characters have to be lower case.

The words can be like this:

```
wezembeek-oppem
roeselare
BRUGGE
louvain-la-neuve

```

Which would have to be:

```
Wezembeek-Oppem
Roeselare
Brugge
Louvain-La-Neuve

```

This should be with an UPDATE statement, I want to update the data of a column.
Thank you very much for your answers in advance, I'm an SQL novice.
