获取错误 "Error occurred during SQL query execution "

Question

运行以下脚本时出错

Error: Error occurred during SQL query execution

Reason:
SQL Error [1]: [SQLITE_ERROR] SQL error or missing database (near "SET": syntax error)

测试数据创建脚本：

SET NOCOUNT ON
DECLARE @counter int = 1

WHILE (@counter <= 100)
BEGIN
    DECLARE @deptno number = 'deptno ' + RTRIM(@counter)
    DECLARE @name varchar2(50) = 'ABC ' + RTRIM(@counter)
    DECLARE @location varchar2(50) = 'xyz' + RTRIM(@counter) + '-USA'
    
    INSERT INTO DEPARTMENTS 
    VALUES (@deptno, @name, @location)
    
    SET @counter = @counter +1
    
    IF (@counter%10 = 0)
        PRINT RTRIM(@counter) + 'rows inserted.'
END;

SqLite 不支持该脚本中的变量。
（看起来像 T-SQL 脚本）

但您也可以通过递归 CTE 生成这些记录。

WITH RECURSIVE RCTE AS (
  SELECT 1 as n
  UNION ALL
  SELECT n+1
  FROM RCTE
  WHERE n < 100
)
INSERT INTO DEPARTMENTS (
 deptno, 
 name, 
 location
)
SELECT n AS deptno
, ('ABC ' || n) AS name
, ('xyz ' || n || '-USA') AS location
FROM RCTE;

select * from DEPARTMENTS order by deptno desc limit 3;

deptno	name	location
100	ABC 100	xyz 100-USA
99	ABC 99	xyz 99-USA
98	ABC 98	xyz 98-USA
