Comment insérer une valeur d'incrémentation automatique dans une table temporaire dans SQL

Question

J'ai une procédure stockée dans laquelle je reçois un numéro de séquence de l'interface utilisateur. La procédure stockée sélectionne les enregistrements d'une table et les insère dans une table temporaire dont la structure est la même que la table d'origine, à l'exception d'une colonne supplémentaire.

Cette colonne contiendra la valeur "numéro de séquence + 1". Et pour les insertions successives, cette valeur s'incrémentera automatiquement. Comment dois-je faire cela? Le nom de la colonne où je veux garder la valeur incrémentée automatique est « REV_SEQ »

Les variables d'identité dynamique ne sont pas possibles avec les variables de table. Utilisez les tables Temp à la place. Modifiez la création de votre table comme ci-dessous.

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);

Answer 2

Je pense qu'il est plus facile de le faire en tout déclarant la colonne à identity:

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 * 
    . . .; 

Ensuite, vous avez cette déclaration:

SELECT @TotalCount = COUNT(1) OVER() FROM @TempMenuResult; 

Cela ne fera probablement pas ce que vous voulez. Vous voulez une agrégation simple, pas une fonction de fenêtre:

SELECT @TotalCount = COUNT(*) FROM @TempMenuResult;
