【问题描述】：

检索本地数据库数据时出现以下错误：

android.database.sqlite.SQLiteException: near "=": syntax error (code 1): , while compiling: SELECT EVENT_USER_ID,EVENT_ID,RINGEE_USER_ID,IS_INVITED,IS_ATTENDING,IS_DELETE FROM user_relationWHERE _ID =1

user_relation 表的查询如下，

public static abstract class UserRelationTable {
    public static final String TABLE_NAME = "user_relation";
    public static final String COL1_EVENT_USER_ID = "EVENT_USER_ID";
    public static final String COL2_EVENT_ID = "EVENT_ID";
    public static final String COL3_RINGEE_USER_ID = "RINGEE_USER_ID";
    public static final String COL4_IS_INVITED = "IS_INVITED";
    public static final String COL5_IS_ATTENDING = "IS_ATTENDING";
    public static final String COL6_IS_DELETE = "IS_DELETE";

    public static final String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + "(" + _ID + " INTEGER PRIMARY KEY," + COL1_EVENT_USER_ID + INTEGER_TYPE + COMMA_SEP + COL2_EVENT_ID + INTEGER_TYPE
            + COMMA_SEP + COL3_RINGEE_USER_ID + INTEGER_TYPE + COMMA_SEP + COL4_IS_INVITED + INTEGER_TYPE + COMMA_SEP + COL5_IS_ATTENDING + INTEGER_TYPE + COMMA_SEP + COL6_IS_DELETE + INTEGER_TYPE + ")";

    public static final String DELETE_TABLE = "DROP TABLE IF EXISTS " + TABLE_NAME;

    public static final String RETRIVE_ALL_USER_DATA = "SELECT " + COL1_EVENT_USER_ID + COMMA_SEP + COL2_EVENT_ID + COMMA_SEP + COL3_RINGEE_USER_ID + COMMA_SEP + COL4_IS_INVITED + COMMA_SEP + COL5_IS_ATTENDING + COMMA_SEP
            + COL6_IS_DELETE + " FROM " + TABLE_NAME + "WHERE _ID =";
}

如何解决这个错误提前谢谢。

【解决方案1】：

WHERE前加空格：

public static final String RETRIVE_ALL_USER_DATA = "SELECT " + COL1_EVENT_USER_ID + COMMA_SEP + COL2_EVENT_ID + COMMA_SEP + COL3_RINGEE_USER_ID + COMMA_SEP + COL4_IS_INVITED + COMMA_SEP + COL5_IS_ATTENDING + COMMA_SEP
            + COL6_IS_DELETE + " FROM " + TABLE_NAME + " WHERE _ID =";

【解决方案2】：

试试这个，

public static final String RETRIVE_ALL_USER_DATA = "SELECT " + COL1_EVENT_USER_ID + COMMA_SEP + COL2_EVENT_ID + COMMA_SEP + COL3_RINGEE_USER_ID + COMMA_SEP + COL4_IS_INVITED + COMMA_SEP + COL5_IS_ATTENDING + COMMA_SEP
            + COL6_IS_DELETE + " FROM " + TABLE_NAME + " WHERE _ID =";

你没有给tablename后面的空格，所以会出现这个错误。

嘿，你检查了吗？
好的，如果这个答案对你有帮助，请点赞。

【解决方案3】：

在您的代码字符串 RETRIVE_ALL_USER_DATA

“WHERE _ID =" 倾向于 ”WHERE _ID =" 始终将此标记为 DATABASE

简单易行

SPACE 之后选择、创建、删除、更新等...

and SPACE both side WHERE,LIKE,IN,FROM,etc.....
