【问题描述】：

无论我如何尝试，我都会不断收到此错误

E/SQLiteLog( 9445): (20) statement aborts at 5: [INSERT Into Profile (mac,image,name,age,nationality,profession,about) VALUES ('0.0.0.0.0.0','/data/user/0/com.shades.flidar/cache/scaled_image_picker5826102720138113893.jpg','test','35',
E/SQLiteQuery( 9445): exception: datatype mismatch (code 20 SQLITE_MISMATCH); query: INSERT Into Profile (mac,image,name,age,nationality,profession,about) VALUES ('0.0.0.0.0.0','/data/user/0/com.test.test/cache/scaled_image_picker5826102720138113893.jpg','test','35','test','test','test');
E/flutter ( 9445): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: DatabaseException(datatype mismatch (code 20 SQLITE_MISMATCH)) sql 'INSERT Into Profile (mac,image,name,age,nationality,profession,about) VALUES ('0.0.0.0.0.0','/data/user/0/com.test.test/cache/scaled_image_picker5826102720138113893.jpg','test','35','test','test','test');' args []

这是代码：

customQuery("CREATE TABLE Profile ("
"mac TEXT,"
"image TEXT,"
"name TEXT,"
"age TEXT,"
"nationality TEXT,"
"profession TEXT,"
"about TEXT"
")");

onPressed: () 
    profile.add(Profile(
        mac: _platformVersion,
        image: imagePath,
        name: nameController.text,
        age: ageController.text,
        nationality: nationalityController.text,
        profession: professionController.text,
        about: aboutController.text));

    DBProvider.db.customQuery("INSERT Into Profile (mac,image,name,age,nationality,profession,about)"
        " VALUES ('$profile[0].mac','$profile[0].image',"
        "'$profile[0].name','$profile[0].age','$profile[0].nationality',"
        "'$profile[0].profession','$profile[0].about');");
       ,

我真的不知道为什么，请帮忙！ 谢谢！

【参考方案1】：

profile[0].age 应该返回一个字符串数据类型。

【讨论】：

谢谢，它确实返回一个字符串值
