Question

我试图创建一个名为“知识”的表

以下是我的查询，

private static final String CREATE_KNOWLEDGE_STATUTORY = "CREATE TABLE " + TABLE_KNOWLEDGE_STATUTORY + "("
            + KEY_ID + " INTEGER PRIMARY KEY,"
            + KEY_STATUTORY_MAPPING + " TEXT,"
            + KEY_LOCATION + " TEXT,"
            + KEY_DESCRIPTION + " TEXT,"
            + KEY_ACTIVE + " TEXT,"
            + KEY_PROVISION + " TEXT,"
            + KEY_COMPLIANCE_TASK + " TEXT,"
            + KEY_FORMAT_FILE_LIST + " TEXT,"
            + KEY_DURATION + " TEXT,"
            + KEY_DOC_NAME + " TEXT,"
            + KEY_PENAL_CONSEQUENCE + " TEXT,"
            + KEY_DURATION_ID + " TEXT,"
            + KEY_FREQUENCY_ID + " INTEGER,"
            + KEY_REPEAT_FREQ + " TEXT,"
            + KEY_COMPLIANCE_ID + " INTEGER,"
            + KEY_REPEAT_TYPE_ID + " TEXT,"
            + KEY_STATUTORY_MONTH + " TEXT,"
            + KEY_STATUTORY_DATE + " TEXT,"
            + KEY_TRIGGER_DATE + " TEXT,"
            + KEY_REPEAT_BY + " TEXT" + ");";

以下是我用来创建它的方法，

public void addStatutory(StatutoryModel statutoryModel) {

        SQLiteDatabase sqLiteDatabase = this.getWritableDatabase();
        ContentValues contentValues = new ContentValues();

        contentValues.put(KEY_ID, statutoryModel.getId());
        contentValues.put(KEY_STATUTORY_MAPPING, statutoryModel.getStatuoryMapping());
        contentValues.put(KEY_LOCATION, statutoryModel.getLocation());
        contentValues.put(KEY_DESCRIPTION, statutoryModel.getDescription());
        contentValues.put(KEY_ACTIVE, statutoryModel.getIsStatutoryActive());
        contentValues.put(KEY_PROVISION, statutoryModel.getStatutoryProvision());
        contentValues.put(KEY_COMPLIANCE_TASK, statutoryModel.getComplianceTask());
        contentValues.put(KEY_FORMAT_FILE_LIST, statutoryModel.getFormat_fileList());
        contentValues.put(KEY_DURATION, statutoryModel.getDuration());
        contentValues.put(KEY_DOC_NAME, statutoryModel.getDocument_name());
        contentValues.put(KEY_PENAL_CONSEQUENCE, statutoryModel.getPenalConsequences());
        contentValues.put(KEY_DURATION_ID, statutoryModel.getDurationType_id());
        contentValues.put(KEY_FREQUENCY_ID, statutoryModel.getFrequencyId());
        contentValues.put(KEY_REPEAT_FREQ, statutoryModel.getRepeatsEvery());
        contentValues.put(KEY_COMPLIANCE_ID, statutoryModel.getComplianceId());
        contentValues.put(KEY_REPEAT_TYPE_ID, statutoryModel.getRepeatsTypeId());
        contentValues.put(KEY_STATUTORY_MONTH, statutoryModel.getStatutory_month());
        contentValues.put(KEY_STATUTORY_DATE, statutoryModel.getStatutory_date());
        contentValues.put(KEY_TRIGGER_DATE, statutoryModel.getTrigger_before_days());
        contentValues.put(KEY_REPEAT_BY, statutoryModel.getRepeat_by());

        sqLiteDatabase.insert(TABLE_KNOWLEDGE_STATUTORY,null,contentValues);
        sqLiteDatabase.close();
    }

我将其作为

调用

DbHandler dbHandler = new DbHandler(getActivity());
dbHandler.addStatutory(new StatutoryModel(i, dbDesc, isStatutoryActive, statutoryProvision, complianceTask, format_fileList, duration, penalConsequences, document_name, durationType_id, frequencyId, repeatsEvery, repeatsTypeId, complianceId, statutory_month, statutory_date, trigger_before_days, repeat_by, compDescription, dbLoc));

问题是，我变得没有这样的表存在错误。以下是我的错误日志。

在任何情况下，这个问题都是重复的，因为它被CL标记为重复，因为问题不在onUpgrade中，而在于运行应用程序而不刷新以前的数据

确保您是否通过调用db.execSQL（CREATE_KNOWLEDGE_STATUTORY）创建了表;在你的DbHandler类的onCreate（）方法？

Answer 2

嘿，我在表创建定义中发现了语法错误。

您必须在常量TABLE_KNOWLEDGE_STATUTORY之后添加一个额外的空格，以便将括号与表名分开。

您的表创建定义应类似于以下内容：

private static final String CREATE_KNOWLEDGE_STATUTORY = "CREATE TABLE " + TABLE_KNOWLEDGE_STATUTORY + " ("
        + KEY_ID + " INTEGER PRIMARY KEY,"
        + KEY_STATUTORY_MAPPING + " TEXT,"
        + KEY_LOCATION + " TEXT,"
        + KEY_DESCRIPTION + " TEXT,"
        + KEY_ACTIVE + " TEXT,"
        + KEY_PROVISION + " TEXT,"
        + KEY_COMPLIANCE_TASK + " TEXT,"
        + KEY_FORMAT_FILE_LIST + " TEXT,"
        + KEY_DURATION + " TEXT,"
        + KEY_DOC_NAME + " TEXT,"
        + KEY_PENAL_CONSEQUENCE + " TEXT,"
        + KEY_DURATION_ID + " TEXT,"
        + KEY_FREQUENCY_ID + " INTEGER,"
        + KEY_REPEAT_FREQ + " TEXT,"
        + KEY_COMPLIANCE_ID + " INTEGER,"
        + KEY_REPEAT_TYPE_ID + " TEXT,"
        + KEY_STATUTORY_MONTH + " TEXT,"
        + KEY_STATUTORY_DATE + " TEXT,"
        + KEY_TRIGGER_DATE + " TEXT,"
        + KEY_REPEAT_BY + " TEXT" + ");";

在表定义中，表未正确创建，因此当您尝试插入新记录时，显然会出现“无此表”错误。

Answer 3

我认为您没有发布正确的错误消息。这是您尝试插入时获得的错误，而不是失败的create table中的错误。你甚至在任何地方执行查询CREATE_KNOWLEDGE_STATUTORY吗？

查看您的创建表，问题可能是最后的;。从Java执行SQL时，不包括;。我认为这会产生错误，例如“无效字符”。

用于创建表的sSQLITE查询无效
