動的SQLの結果をsql-serverの変数に取得する

ストアドプロシージャで次のように動的SQLを実行します。

DECLARE @sqlCommand nvarchar(1000)
DECLARE @city varchar(75)
SET @city = 'London'
SET @sqlCommand = 'SELECT COUNT(*) FROM customers WHERE City = @city'
EXECUTE sp_executesql @sqlCommand, N'@city nvarchar(75)', @city = @city

count（*）列の値をSPの戻り値として使用するにはどうすればよいですか？

DECLARE @sqlCommand nvarchar(1000)
DECLARE @city varchar(75)
declare @counts int
SET @city = 'New York'
SET @sqlCommand = 'SELECT @cnt=COUNT(*) FROM customers WHERE City = @city'
EXECUTE sp_executesql @sqlCommand, N'@city nvarchar(75),@cnt int OUTPUT', @city = @city, @cnt=@counts OUTPUT
select @counts as Counts

あなたはおそらくこれを試しましたが、あなたがこれを行うことができるような仕様ですか？

DECLARE @city varchar(75)
DECLARE @count INT
SET @city = 'London'
SELECT @count = COUNT(*) FROM customers WHERE City = @city

動的バージョン

    ALTER PROCEDURE [dbo].[ReseedTableIdentityCol](@p_table varchar(max))-- RETURNS int
    AS
    BEGIN
        -- Declare the return variable here
       DECLARE @sqlCommand nvarchar(1000)
       DECLARE @maxVal INT
       set @sqlCommand = 'SELECT @maxVal = ISNULL(max(ID),0)+1 from '+@p_table
       EXECUTE sp_executesql @sqlCommand, N'@maxVal int OUTPUT',@maxVal=@maxVal OUTPUT
       DBCC CHECKIDENT(@p_table, RESEED, @maxVal)
    END


exec dbo.ReseedTableIdentityCol @p_table='Junk'

DECLARE @sqlCommand nvarchar(1000)
DECLARE @city varchar(75)
DECLARE @cnt int
SET @city = 'London'
SET @sqlCommand = 'SELECT @cnt=COUNT(*) FROM customers WHERE City = @city'
EXECUTE sp_executesql @sqlCommand, N'@city nvarchar(75)', @city = @city
RETURN @cnt

これは解決策になりますか？

declare @step2cmd nvarchar(200)
DECLARE @rcount NUMERIC(18,0)   
set @step2cmd = 'select count(*) from uat.ap.ztscm_protocollo' --+ @nometab
EXECUTE @rcount=sp_executesql @step2cmd
select @rcount

 vMYQUERY := 'SELECT COUNT(*) FROM ALL_OBJECTS WHERE OWNER = UPPER(''MFI_IDBI2LIVE'') AND OBJECT_TYPE = ''TABLE'' 
    AND OBJECT_NAME  =''' || vTBL_CLIENT_MASTER || '''';
    PRINT_STRING(VMYQUERY);
    EXECUTE IMMEDIATE  vMYQUERY INTO VCOUNTTEMP ;
