Question

我正在尝试设置两个数据库。午餐后，模拟器，并试图输入数据，我试图找到这个错误的确切原因，但没有成功。

我收到错误：

05-17 16：23：06.410：E / AndroidRuntime（311）：android.database.sqlite.SQLiteException：near＆＃34; NULLbaby_age_month＆＃34;：语法错误：CREATE TABLE设置（_id INTEGER PRIMARY KEY AUTOINCREMENT， uri_baby TEXT NOT NULL，baby_name TEXT NOT NULL，baby_gender TEXT NOT NULL，baby_age_year TEXT NOT NULLbaby_age_month TEXT NOT NULLbaby_age_day TEXT NOT NULL）;

Answer 1

忘记在查询中添加,

TEXT NOT NULL,baby_age_month

和

TEXT NOT NULL,baby_age_day

CREATE TABLE settings ( _id INTEGER PRIMARY KEY AUTOINCREMENT, uri_baby TEXT NOT NULL, baby_name TEXT NOT NULL, baby_gender TEXT NOT NULL, baby_age_year TEXT NOT NULL,baby_age_month TEXT NOT NULL,baby_age_day TEXT NOT NULL);

Answer 2

有小错误：遗忘（，）分隔符

CREATE TABLE settings ( _id INTEGER PRIMARY KEY AUTOINCREMENT, uri_baby TEXT NOT NULL, 
baby_name TEXT NOT NULL, baby_gender TEXT NOT NULL, baby_age_year TEXT NOT 
NULL, baby_age_month TEXT NOT NULL,baby_age_day TEXT NOT NULL);

android app db.execSQL - 创建两个数据库sqlite
