Question

如何在SQL Server中将值设置为声明的变量。

DECLARE  @V_SEQUENCE INT,  @V_SEQUENCENAME NVARCHAR(MAX);
SET @V_SEQUENCENAME = 'dbo.MYSEQ';   
EXEC('SELECT @V_SEQUENCE = NEXT VALUE FOR  ' + @V_SEQUENCENAME)
SELECT @V_SEQUENCE

我在这里收到错误：

必须声明标量变量＆＃34; @ V_SEQUENCE＆＃34;＆＃39;

请告诉我如何获得@V_SEQUENCE的结果。

您想要从执行中传递一个值。我建议您使用DECLARE @V_SEQUENCE INT, @V_SEQUENCENAME NVARCHAR(MAX), @SQL NVARCHAR(MAX); SET @V_SEQUENCENAME = 'dbo.MYSEQ'; SELECT @SQL = 'SELECT @V_SEQUENCE = NEXT VALUE FOR ' + @V_SEQUENCENAME; EXEC sp_executesql @SQL, N'@V_SEQUENCE INT OUTPUT', @V_SEQUENCE = @V_SEQUENCE OUTPUT; SELECT @V_SEQUENCE;：
