如何在SQL中的临时表中插入自动增量值
我有一个存储过程，从用户界面接收序列号。存储过程将从表中选择记录，并将其插入临时表中，该临时表的结构与原始表相同，只是增加了一列 此列将保存值序列号+1。对于连续插入，该值将自动递增。我该怎么做？我希望保留自动递增值的列名是REV_SEQ如何在SQL中的临时表中插入自动增量值,sql,stored-procedures,row,identity,sql-server-2016,Sql,Stored Procedures,Row,Identity,Sql Server 2016,我有一个存储过程，从用户界面接收序列号。存储过程将从表中选择记录，并将其插入临时表中，该临时表的结构与原始表相同，只是增加了一列 此列将保存值序列号+1。对于连续插入，该值将自动递增。我该怎么做？我希望保留自动递增值的列名是REV_SEQ ALTER PROCEDURE [PCC_APP_OWN].[Doc_GetBlChargePatternData] @RevSeq INT NULL = 0, @TotalCount INT OUTPUT AS BEGI

我认为通过将列声明为identity更容易做到这一点： 那么你有这样的说法：
SELECT @TotalCount = COUNT(1) OVER () FROM @TempMenuResult;
SELECT @TotalCount = COUNT(*) FROM @TempMenuResult;
对于表变量，动态标识种子是不可能的。使用临时表代替。如下所示修改表的创建

标记您正在使用的dbms。该代码是特定于产品的。SQL Server 2016尝试在创建列REV_SEQ INT Identity RevSeq，1时，不在其中插入任何内容。。。所以它将从参数中的RevSeq数开始，并继续为每个条目增加1，即使用RevSeq+1，1。。。取决于要从哪个数字开始，然后从其他查询中删除插入到该列中必须声明表变量@TempMenuResult。这就是我在实现代码后遇到的错误。。执行INSERT语句时出错将@TempMenuResult更改为TempMenuResult。在进一步的SP代码中。它在第一次执行时成功返回结果。但在下一次执行时，它给出了一个错误，数据库中已经有一个名为“TempMenuResult”的对象。没有找到它。。。编辑以包括DROP TABLE TempMenuResult；在查询中，您可以告诉我如果不使用动态sql，创建临时表的语法是什么。更准确地说，我需要标识列的语法，即创建表TempMenuResult REV_SEQ INT identity'+CAST@tempRevSeq作为varchar15+'，1不能为NULL，因为不接受单引号
