我有一个存储过程，我从用户界面接收序列号。存储过程将从表中选择记录并将它们插入到临时表中，该表的结构与原始表相同，但附加列除外。
此列将保存值＆＃34;序号+ 1＆＃34;。对于连续插入，此值将自动递增。我该怎么做？我希望保留自动递增值的列名是＆＃34; REV_SEQ＆＃34;

我认为通过将列声明为identity来更容易实现此目的：
DECLARE @TempMenuResult AS TABLE (REV_SEQ INT IDENTITY, . . .);
. . .
INSERT INTO @TempMenuResult (CHRG_PTRN_DTL_ID, UPDT_STAMP, UPDT_USER, ORGL_STAMP, ORGL_USER, DEL_FLG, CHRG_PTRN_HDR_ID, SEQ, CHRG_CODE, PORT_CODE, BASIS, UM, RATE, CURRENCY, PER, PREPAID_COLLECT, INV_OFC)
SELECT *
. . .;
然后你有这个陈述：
SELECT @TotalCount = COUNT(1) OVER () FROM @TempMenuResult;
这可能不会做你想要的。你想要简单的聚合，而不是窗口函数：
SELECT @TotalCount = COUNT(*) FROM @TempMenuResult;

表变量无法实现动态身份种子。请改用Temp表。修改您的表创建如下。
DECLARE @sql varchar(8000);
SET @sql = 'DROP TABLE ##TempMenuResult; CREATE TABLE ##TempMenuResult (REV_SEQ INT IDENTITY('+ CAST(@tempRevSeq AS varchar(15)) + ', 1) NOT NULL ,
CHRG_PTRN_DTL_ID INT,
UPDT_STAMP DATETIME,
UPDT_USER VARCHAR(12),
ORGL_STAMP DATETIME,
ORGL_USER VARCHAR(12),
DEL_FLG VARCHAR(1),
CHRG_PTRN_HDR_ID INT,
SEQ INT,
CHRG_CODE VARCHAR(3),
PORT_CODE VARCHAR(7),
BASIS VARCHAR(2),
UM VARCHAR(2),
RATE DECIMAL(8,2),
CURRENCY VARCHAR(3),
PER VARCHAR(2),
PREPAID_COLLECT VARCHAR(1),
INV_OFC VARCHAR(6)
);'
EXEC (@sql);
