sql-server - テーブルからの動的 SQL 値

Question

現在動的クエリを使用しており、テーブルの値が必要です。

これまでの私のクエリ：

DECLARE @query varchar(1500)
SET @query = 
'SELECT Id,'
+ 'SUM(CASE WHEN ['+convert(varchar(50),CAST(myTable.myDate AS date),120)+'] = ['+convert(varchar(50), CAST(GETDATE() AS date), 120)+'] then [Counter] else 0 end) ''0'','
+ 'SUM(CASE WHEN ['+convert(varchar(50),CAST(DATEADD(day, -1, myTable.myDate)), 120)+'] = ['+convert(varchar(50),CAST(DATEADD(day, -1, GETDATE()) AS date), 120)+'] then [counter] else 0 end) ''1'','
+ 'SUM(CASE WHEN ['+convert(varchar(50),CAST(DATEADD(day, -2, myTable.myDate)), 120)+'] = ['+convert(varchar(50),CAST(DATEADD(day, -2, GETDATE()) AS date), 120)+'] then [counter] else 0 end) ''2'','
+ 'SUM(CASE WHEN ['+convert(varchar(50), CAST(DATEADD(day, -3, myTable.myDate)), 120)+'] = ['+convert(varchar(50),CAST(DATEADD(day, -3, GETDATE()) AS date),120)+'] then [counter] else 0 end) ''3'','
+ 'SUM(CASE WHEN ['+convert(varchar(50),CAST(DATEADD(day, -4, myTable.myDate)),120)+'] = ['+convert(varchar(50),CAST(DATEADD(day, -4, GETDATE()) AS date),120)+'] then [counter] else 0 end) ''4'''
+ 'FROM [myTable] GROUP BY Id'
PRINT(@query)
EXEC(@query)

「マルチパート識別子「myTable」をバインドできませんでした」と表示されるため、これは機能しません。行 4-8。

私は人々がこのようなものを推奨しているのを見てきました:

CREATE TABLE #tmp
(
    id varchar(50),
    counter int,
    myDate smalldatetime
)
Insert Into #tmp (id, counter, myDate)
SELECT * FROM myTable
--GO                       --doesn't work either with or without 'go'
DECLARE @query varchar(1500)
SET @query = 
'SELECT Id,'
+ 'SUM(CASE WHEN ['+convert(varchar(50),CAST(#tmp.myDate AS date),120)+'] = ['+convert(varchar(50), CAST(GETDATE() AS date), 120)+'] then [counter] else 0 end) ''0'','
+ 'SUM(CASE WHEN ['+convert(varchar(50),CAST(DATEADD(day, -1, #tmp.myDate)), 120)+'] = ['+convert(varchar(50),CAST(DATEADD(day, -1, GETDATE()) AS date), 120)+'] then [counter] else 0 end) ''1'','
+ 'SUM(CASE WHEN ['+convert(varchar(50),CAST(DATEADD(day, -2, #tmp.myDate)), 120)+'] = ['+convert(varchar(50),CAST(DATEADD(day, -2, GETDATE()) AS date), 120)+'] then [counter] else 0 end) ''2'','
+ 'SUM(CASE WHEN ['+convert(varchar(50),CAST(DATEADD(day, -3, #tmp.myDate)), 120)+'] = ['+convert(varchar(50),CAST(DATEADD(day, -3, GETDATE()) AS date),120)+'] then [counter] else 0 end) ''3'','
+ 'SUM(CASE WHEN [+'convert(varchar(50),CAST(DATEADD(day, -4, #tmp.myDate)), 120)+'] = ['+convert(varchar(50),CAST(DATEADD(day, -4, GETDATE()) AS date),120)+'] then [aounter] else 0 end) ''4'''
+ 'FROM [myTable] GROUP BY Id'
PRINT(@query)
EXEC(@query)

それでもうまくいきません。助けてください！

私の問題の簡易版：

DECLARE @query varchar(1500)
SET @query = 'SELECT ['+myTable.value+'] FROM [myTable]'
EXEC(@query)

動作しません
