Question

我尝试使用Case和SET NOEXEC ON但是出现以下错误：

语法错误：意外＆＃39;设置＆＃39; （集）

语法错误：缺少＆＃39;右括号＆＃39;

INSERT INTO tag (table, repr, tag, value) SELECT 'product' AS table, @Id AS repr, 'product_code' AS tag, CASE @Code WHEN NOT null THEN @Code ELSE SET NOEXEC ON END AS value

@Id和@Code是脚本中的声明参数

Answer 1

SET NOEXEC ON -- is a command and not a value, so you can't use it in insert statment.

尝试下面的sql（ms - sql）


if(@Code is not null)
begin
INSERT INTO tag (table, repr, tag, value)
    SELECT 'product' AS table,
           @Id AS repr,
           'product_code' AS tag,
           @Code AS value
end

如果insert值为null，如何设置值为null，如何停止脚本执行？
