sqlite - SQLite Manager INSERT INTO 失败但不产生错误

Question

我有一个有一个表的 SQLite DB：

table: import_info
   Columns: First_Name, Last_Name, Payroll_ID, ... other columns not used

tabel employees
   Columns: name, employee_num

我想从第一个表中选择唯一名称和 payroll_id 到员工表中，并作为name和employee_num。

如果我在 SQLite Manager 中选择表并运行：

SELECT DISTINCT Last_Name || ' ' || First_Name AS name, Payroll_ID 
AS employee_num 
FROM import_info

我得到了完美的结果。但如果我尝试：

INSERT INTO employees (name, employee_num)
SELECT DISTINCT Last_Name || ' ' || First_Name AS name, Payroll_ID 
AS employee_num 
FROM import_info

我什么都得不到。没有错误，没有任何反应。

Answer 1

您可以提供以下值：

INSERT INTO employees(name, employee_num, created_at, updated_at)
    SELECT DISTINCT Last_Name || ' ' || First_Name AS name, Payroll_ID,
           datetime('now'), datetime('now')
    FROM import_info

然而，我很惊讶，省略这些值不会导致错误。也许某些东西正在抑制错误。
