这是我的错误编码我创建了一个名为“详细信息”的表以下是该表的数据库代码，插入方法为“insertDescription”

public void insertDescription(int rid, String name, String phoneno, String email, String subject, String desc){
    ContentValues cv = new ContentValues();
    cv.put("_rid", rid);
    cv.put("name", name);
    cv.put("phoneno", phoneno);
    cv.put("email", email);
    cv.put("subject", subject);
    cv.put("desc", desc);
    Log.d("DB", "Record is here!");
    sdb.insert("details", null, cv);
}
@Override
public void onCreate(SQLiteDatabase arg0) {
arg0.execSQL("CREATE TABLE users ( _uid INTEGER PRIMARY KEY, name TEXT, mail TEXT, password TEXT, hint TEXT);");
arg0.execSQL("CREATE TABLE details (_rid INTEGER PRIMARY KEY, name TEXT, " +
            "phoneno VARCHAR(10) CONSTRAINT phone CHECK(phoneno LIKE '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]')," +
" email TEXT, subject TEXT, desc TEXT);");
}

使用上面的我通过以下java代码将值插入数据库

String rnos = rno.getText().toString();
int rnoz = Integer.parseInt(rnos);
String names = name.getText().toString();
String mobiles = mobile.getText().toString();
String emailids = emailid.getText().toString();
String subjects = subject.getText().toString();
String descs = desc.getText().toString();
String dates = date.getText().toString();
if(rnos.isEmpty() || names.isEmpty() || mobiles.isEmpty()
    || emailids.isEmpty() || subjects.isEmpty()|| descs.isEmpty() || dates.isEmpty()){
    Toast.makeText(getApplicationContext(), "All Fields are Mandatory", Toast.LENGTH_LONG).show();
    }else{
        mdb.openDB();
        mdb.insertDescription(rnoz, names, mobiles, emailids, subjects, descs);
        Toast.makeText(getApplicationContext(), "Record Saved Successfully!", Toast.LENGTH_LONG).show();
        }
        mdb.closeDB();

发生以下错误。我不知道如何处理我刚从朋友那里得到这个查询约束查询的 SQL 查询。无论如何，表创建成功我在程序执行后看到了该表结构。以下是我的错误日志

我希望由于我在查询中给出的约束语句而发生错误。在 Java 'insertDescription()' 的插入方法中，我试图将所有内容保存为字符串。如果有更好的查询或可用的替代方案建议我，我的完整项目 zip 不完整（我坚持查询的中间）skydrive

LIKE不支持字符类。您收到一个错误，因为您的电话号码的第一个字符 is not [，或者第二个 is not 0，或者第三个 is not -，等等。

替换LIKE为GLOB。

你有问题 phoneno VARCHAR(10) CONSTRAINT phone CHECK(phoneno LIKE '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]')

在以下代码中

arg0.execSQL("CREATE TABLE details (_rid INTEGER PRIMARY KEY, name TEXT, " +
            "phoneno VARCHAR(10) CONSTRAINT phone CHECK(phoneno LIKE '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]')," +
" email TEXT, subject TEXT, desc TEXT);");
