選択した値を印刷しようとしていますが、これは可能ですか?
例:
PRINT
SELECT SUM(Amount) FROM Expense
選択した値を印刷しようとしていますが、これは可能ですか?
例:
PRINT
SELECT SUM(Amount) FROM Expense
もっと簡単な方法があるかもしれませんが、最初に頭に浮かぶのは次のとおりです。
Declare @SumVal int;
Select @SumVal=Sum(Amount) From Expense;
Print @SumVal;
もちろん、この方法でテーブルから任意の数のフィールドを印刷できます。もちろん、複数の行を返すクエリからのすべての結果を印刷したい場合は、出力を適切に (たとえば、テキストに) 送信するだけです。
XML として表示しても問題ない場合:
DECLARE @xmltmp xml = (SELECT * FROM table FOR XML AUTO)
PRINT CONVERT(NVARCHAR(MAX), @xmltmp)
尋ねられたOPの質問は必ずしもこれを必要とするわけではありませんが、複数の行/列を(理由の範囲内で)印刷しようとしている場合に役立ちます。
複数の行を印刷する場合は、カーソルを使用して結果を反復処理できます。たとえば、sys.database_principals からすべての名前を出力します。
DECLARE @name nvarchar(128)
DECLARE cur CURSOR FOR
SELECT name FROM sys.database_principals
OPEN cur
FETCH NEXT FROM cur INTO @name;
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT @name
FETCH NEXT FROM cur INTO @name;
END
CLOSE cur;
DEALLOCATE cur;
set @n = (select sum(Amount) from Expense)
print 'n=' + @n
私はあなたが望むことをするためにこのSPを書きましたが、動的SQLを使用する必要があります。

複数の結果を出力したい場合は、行を選択して一時テーブルに入れ、その一時テーブルから選択してバッファに入れてから、バッファを出力します。
drop table if exists #temp
-- we just want to see our rows, not how many were inserted
set nocount on
select * into #temp from MyTable
-- note: SSMS will only show 8000 chars
declare @buffer varchar(MAX) = ''
select @buffer = @buffer + Col1 + ' ' + Col2 + CHAR(10) from #temp
print @buffer
すべてのテーブルに対してこれを行う場合は、文書化されていないsp_MSforeachtableストアド プロシージャをそのまま使用することもできます。
sp_MSforeachtable @command1 ="PRINT 'TABLE NAME: ' + '?' DECLARE @RowCount INT SET @RowCount = (SELECT COUNT(*) FROM ?) PRINT @RowCount"
