如何在 SQL 中的临时 table 中插入自动增量值
How to insert auto increment value in temporary table in SQL
我有一个存储过程，我在其中从用户界面接收序列号。存储过程将从 table 中 select 记录并将它们插入临时 table 中，其结构与原始 table 相同，除了一个额外的列。
此列将包含值 "Sequence Number + 1"。对于连续的插入，这个值会自动递增。我应该怎么做？我要保留自动增量值的列名称是 "REV_SEQ"
ALTER PROCEDURE [PCC_APP_OWN].[Doc_GetBlChargePatternData]
@RevSeq INT NULL = 0,
@TotalCount INT OUTPUT
AS
BEGIN
DECLARE @DscgPort VARCHAR(7);
DECLARE @tempRowId INT;
DECLARE @tempRevSeq INT;
SET @tempRevSeq = @RevSeq + 1;
DECLARE @TempMenuResult AS TABLE (REV_SEQ INT,
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)
);
SELECT @DscgPort = DSCH_PORT
FROM BL
WHERE BL_NO_UID = 1 AND CA_SEQ = 0;
INSERT INTO @TempMenuResult (REV_SEQ, 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
IDENTITY(INT, @RevSeq, 1) AS id, *
FROM
CHRG_PTRN_DTL CHG_1
WHERE
CHG_1.CHRG_PTRN_HDR_ID = @ChargePtrnHdrId
AND CHG_1.PORT_CODE = @DscgPort
AND CHG_1.DEL_FLG = 'N'
UNION
SELECT
IDENTITY(INT, @RevSeq, 1) AS id, *
FROM
CHRG_PTRN_DTL CHG_2
WHERE
CHG_2.PORT_CODE IS NULL
AND CHG_2.DEL_FLG = 'N';
SELECT @TotalCount = COUNT(1) OVER () FROM @TempMenuResult;
SELECT * FROM @TempMenuResult ORDER BY REV_SEQ;
END
我认为通过将列声明为 identity:
更容易做到这一点
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 *
. . .;
然后你有这个语句：
SELECT @TotalCount = COUNT(1) OVER () FROM @TempMenuResult;
这可能不会如您所愿。您想要简单的聚合，而不是 window 函数：
SELECT @TotalCount = COUNT(*) FROM @TempMenuResult;
Table 变量无法使用动态身份种子。请改用 Temp tables。修改您的 table 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_USER VARCHAR(12),

EXEC (@sql);
