Question

我使用以下代码使用Sqlite创建数据库。我已将自动增量设置为列。当我尝试向表中插入值时，它会给出错误。

db.execSQL("CREATE TABLE IF NOT EXISTS "
                + SAMPLE_TABLE_NAME
                + " (user_id INTEGER PRIMARY KEY AUTOINCREMENT, username VARCHAR,age VARCHAR, zipcode VARCHAR,gender VARCHAR,isstored VARCHAR);");
        db.execSQL("INSERT INTO " + SAMPLE_TABLE_NAME + " Values ("
                + "\"" + name + "\"," + "\"" + age
                + "\",\"" + zip + "\",\"" + gender + "\", \""
                + "ok" + "\");");

错误：

 09-28 09:44:54.545: E/AndroidRuntime(3825): java.lang.RuntimeException: Unable to   start activity ComponentInfo{com.readometer/com.readometer.ReadometerSplash}: 
android.database.sqlite.SQLiteException: table USERDETAILS has 6 columns but 5 values were supplied (code 1): , while compiling: INSERT INTO USERDETAILS Values ("kumar","23","1234","M", "ok");

Answer 1

当您尝试插入时，应以这种方式插入。 SQlite框架将自动将自动递增的值插入user_id列。

INSERT INTO test.authors (username,age, zipcode,gender,isstored) VALUES ("kumar","23","1234","M", "ok");

Answer 2

您应该做一些更干净的事情，首先将所有列属性声明为常量，然后使用以下代码在数据库中进行正确的插入：

ContentValues values = new ContentValues();
values.put(USERNAME, name);
values.put(AGE, age
values.put(ZIPCODE, zip);
values.put(GENDER, gender);
values.put(STORED, ok);
db.insert(SAMPLE_TABLE_NAME, null, values);

Answer 3

试试这段代码：

SQLiteDatabase s =getWritableDatabase();
s.execSQL( "INSERT INTO requestmsg (username ,age , zipcode ,gender ,isstored ) " +                 "VALUES ('" + name + "', '" + age+ "','" +  zip+ "','"+gender+"','ok')");

Answer 4

试试如下：

sql = "INSERT INTO "+ SAMPLE_TABLE_NAME + "( username,age,zipcode,gender,isstored) " +
"VALUES ('" + name + "', '" + age + "','" + zip+ "' ,'" +gender + "' ,'"ok"' )";
db.execSQL(sql);

将自动增量设置为android中Sqlite数据库中的列
