引起：android.database.sqlite.SQLiteException：“Appliances”附近：语法错误（代码1）：

Question

我在 SQLITE 中有 5 个表，当我尝试编译时显示“语法错误”但我在代码中找不到任何语法错误。

这是我的代码

override fun onCreate(db: SQLiteDatabase?) {
        var ClothTable = "CREATE TABLE $Cloth (_id INTEGER PRIMARY KEY AUTOINCREMENT,Description TEXT ,IMAGE BLOB)"
        var DairyTable = "CREATE TABLE $Dairy (_id INTEGER PRIMARY KEY AUTOINCREMENT,Description TEXT ,IMAGE BLOB)"
        var EATable = "CREATE TABLE $ElectricalAppliances (_id INTEGER PRIMARY KEY AUTOINCREMENT,Description TEXT ,IMAGE BLOB)"
        var FoodTable = "CREATE TABLE $Food (_id INTEGER PRIMARY KEY AUTOINCREMENT,Description TEXT ,IMAGE BLOB)"
        var VegetableTable = "CREATE TABLE $vegetable (_id INTEGER PRIMARY KEY AUTOINCREMENT,Description TEXT ,IMAGE BLOB)"

        db?.execSQL(ClothTable)
        db?.execSQL(DairyTable)
        db?.execSQL(EATable)
        db?.execSQL(FoodTable)
        db?.execSQL(VegetableTable)


    }

错误是：

Caused by: android.database.sqlite.SQLiteException: near "Appliances": syntax error (code 1): , while compiling: CREATE TABLE Electrical Appliances (_id INTEGER PRIMARY KEY AUTOINCREMENT,Description STRING ,IMAGE BLOB)

我猜你已经像这样声明了变量 ElectricalAppliances：

val ElectricalAppliances = "Electrical Appliances"

作为表名，但不允许有空格。
改成：

val ElectricalAppliances = "[Electrical Appliances]"

名称必须用方括号 [ ] 或反引号 `（ascii 代码 096）括起来。
