Question

public static final String DB_NAME = "task_management";
public static final int DB_VERSION = 1;

public static final String EMPLOYEE_TABLE = "employee";
public static final String ID_FIELD = "_id";
public static final String NAME_FIELD = "name";
public static final String TIME_DATE = "time_date";

public static final String EMPLOYEE_TABLE_SQL = "CREATE TABLE"
        + EMPLOYEE_TABLE + "(" + ID_FIELD + "INTEGER PRIMARY KEY,"
        + NAME_FIELD + "name," + TIME_DATE + "time_date,)";

我的数据库有什么问题？

我的日志猫显示

“TABLEemployee”：语法错误。

如何解决？

Answer 1

在...TABLE"和EMPLOYEE_TABLE ...

之间添加空格

像：

EMPLOYEE_TABLE_SQL = "CREATE TABLE " + EMPLOYEE_TABLE...
                                  ^
                              add space here

Answer 2

public static final String EMPLOYEE_TABLE_SQL = 
        "CREATE TABLE " + EMPLOYEE_TABLE 
        + "(" + ID_FIELD + "integer primary key autoincrement," 
        + NAME_FIELD + "string," + TIME_DATE + "datetime)" 
        + ");";

这个怎么样？

Answer 3

您的员工表sql不正确。除了语法错误（缺少空格，缺少结束分号）之外，还需要为TIME_DATE列定义数据类型。

顺便说一下，我实际上已经在SQLite数据库上执行这个sql语句了，但它确实有效。

试试这个：

    public static final String EMPLOYEE_TABLE_SQL = "CREATE TABLE "
        + EMPLOYEE_TABLE + " (" + ID_FIELD + " INTEGER PRIMARY KEY, "
        + NAME_FIELD + " TEXT, " + TIME_DATE + " DATETIME);";
