将递归查询添加到具有声明的组合查询组

Question

我正在尝试向这个巨大的查询片段添加另一个查询 - 除了最后一部分anotherQuery之外一切正常 - 我已经分别编写了anotherQuery，然后尝试将其与其他人一起粉碎但是 - 产生一个错误，读取DECLARE附近的'不正确的语法。期待'（'或SELECT'

如果没有声明，我不确定如何重写它？或者，如果我能找到我的错误？

Answer 1

您应该将所有DECLARES移到顶部。像Tab所说，你不能在CTE中声明一个变量。不知道他对剩下的意思是什么，你可以在顶部声明变量，并在以后的任何地方使用它们

Answer 2

未经测试，但我认为它会像这样工作：

DECLARE
    @UserId BIGINT = 31946,
    @StartDateOfWeek DATETIME = '8/4/2014',
    @EndDateOfWeek DATETIME = '8/10/2014';

DECLARE @insertedDate date = @StartDateOfWeek
DECLARE @days_table TABLE (days DATE); 

WHILE @insertedDate<@EndDateOfWeek
BEGIN
INSERT INTO @days_table (days) values (@insertedDate);
set @insertedDate=DATEADD(D,1,@insertedDate)
END
INSERT INTO @days_table (days) values (@EndDateOfWeek);

WHILE @insertedDate<@EndDateOfWeek
BEGIN
INSERT INTO @days_table (days) values (@insertedDate);
set @insertedDate=DATEADD(D,1,@insertedDate)
END
INSERT INTO @days_table (days) values (@EndDateOfWeek);
