Question

问题出在哪里？我想用以下SQL语句创建一个表。但我得到一个例外＆＃34;删除＆＃34;。

 android.database.sqlite.SQLiteException: near "delete": syntax error (code 1):   , while compiling: CREATE TABLE data_base_stuff( _id INTEGER PRIMARY KEY AUTOINCREMENT,title TEXT,color TEXT,priority TEXT,created_date TEXT,delete INTEGER)

        at android.database.sqlite.SQLiteConnection.nativePrepareStatement(Native Method)
        at android.database.sqlite.SQLiteConnection.acquirePreparedStatement(SQLiteConnection.java:889)
        at android.database.sqlite.SQLiteConnection.prepare(SQLiteConnection.java:500)
        at android.database.sqlite.SQLiteSession.prepare(SQLiteSession.java:588)
        at android.database.sqlite.SQLiteProgram.<init>(SQLiteProgram.java:58)
        at android.database.sqlite.SQLiteStatement.<init>(SQLiteStatement.java:31)
        at android.database.sqlite.SQLiteDatabase.executeSql(SQLiteDatabase.java:1674)
        at android.database.sqlite.SQLiteDatabase.execSQL(SQLiteDatabase.java:1605)

这是例外

private static final String TEXT_TYP = " TEXT";
private static final String COMMA = ",";
private static final String INTEGER_TYP = " INTEGER";

private static final String SQL_CREATE_TABLE_DATABASE_STUFF = "CREATE TABLE "
        + CheckListColumns.TABLE_NAME + "( "
        + CheckListColumns._ID + INTEGER_TYP + " PRIMARY KEY AUTOINCREMENT,"
        + CheckListColumns.COLUMN_NAME_TITLE + TEXT_TYP + COMMA
        + CheckListColumns.COLUMN_NAME_COLOR + TEXT_TYP + COMMA
        + CheckListColumns.COLUMN_NAME_PRIORITY + TEXT_TYP + COMMA
        + CheckListColumns.COLUMN_NAME_CREATED_DATE + TEXT_TYP + COMMA
        + CheckListColumns.COLUMN_NAME_DELETE + INTEGER_TYP + ")";

结束这是我的代码

delete是一个关键字，按原样解释，而不是列名。为了保留该名称，您需要按照here

所述的反引号将其包围
