J'essaie de créer un nouveau champ dans ma table d'attributs et de mettre des valeurs d'un autre champ après la conversion de caractère en entier, mais je ne peux pas obtenir la bonne syntaxe. Je l'exécute comme shell-script dans MSYS.
cd D:/GIS_DataBase/CorineLC/shps_app_and_extr/
myfile=extr_and_app.shp
name=${myfile%.shp}
ogrinfo $myfile -sql "ALTER TABLE $name ADD COLUMN code_num int(3)"
ogrinfo $myfile -sql "UPDATE TABLE $name SET code_num = CONVERT(code_06 As int(3))"
Message d'erreur (MSYS):
Kay@KAY-PC /c/users/kay/desktop/bash
$ sh calc_field_shp.sh
Warning 6: Unsupported column type 'int'. Defaulting to VARCHAR

Edit - Un autre coup avec SQLite:
cd D:/GIS_DataBase/CorineLC/shps_app_and_extr/
myfile=extr_and_app.dbf
name=${myfile%.dbf}
ogrinfo $myfile -sql "ALTER TABLE $name DROP COLUMN code_num"
ogrinfo $myfile -sql "ALTER TABLE $name ADD COLUMN code_num integer(3)"
ogrinfo $myfile -dialect SQLite -sql "UPDATE $name SET code_num = CAST(code_06 As integer(3))"
