Wie Auto-Inkrement-Wert in temporäre Tabelle in SQL

Question

einfügen Ich habe eine gespeicherte Prozedur, wo ich eine Sequenznummer von der Benutzeroberfläche empfangen. Die gespeicherte Prozedur wählt Datensätze aus einer Tabelle aus und fügt sie in eine temporäre Tabelle ein, deren Struktur der ursprünglichen Tabelle entspricht, mit Ausnahme einer zusätzlichen Spalte.

Diese Spalte enthält den Wert "Sequence Number + 1". Bei aufeinanderfolgenden Einfügungen wird dieser Wert automatisch erhöht. Wie soll ich das machen? Der Spaltenname, wo ich das Auto erhöhte Wert halten wollen, ist „REV_SEQ“

Dynamic Identity-Seeds sind nicht mit Tabellenvariablen möglich. Verwenden Sie stattdessen Temp-Tabellen. Ändern Sie Ihre Tabellenerstellung wie folgt.

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); 
    --Your code here to further process ##TempMenuResult

EDIT geändert: Wenn Sie die dynamische SQL nicht verwenden möchten, verwenden Sie DBCC CHECK reseed.

ALTER PROCEDURE [PCC_APP_OWN].[Doc_GetBlChargePatternData]

     DROP TABLE ##TempMenuResult;

Answer 2

Ich denke, dass es einfacher ist, dies zu tun, indem Sie einfach die Spalte erklärt identity zu sein:

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 * 
    . . .; 

Dann haben Sie diese Aussage:

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

Tis wird wahrscheinlich nicht tun, was Sie wollen. Sie möchten einfache Aggregation, keine Fensterfunktion:

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