SQL Server存储过程中的错误处理

我有一个相当复杂的SP（逻辑智慧）嵌套IF BEGIN END ELSE，这个嵌套逻辑中存在多个端点，其中逻辑失败，并且两个地方导致成功并且SQL存在付诸行动。SQL Server存储过程中的错误处理

如何，在SP结束我可以捕获错误，并做了IF Error Count>0 THEN ROLLBACK

DECLARE @errCount int=0 
DECLARE @DataSetCount int=0 
DECLARE @countCurrent int=0 
DECLARE @countHistorical int=0 


IF (isnumeric(@DataSetID)=(0) OR @DataSetID=(0)) 
BEGIN 
    RAISERROR('The DataSet specfied does not appear to be valid', 5, 1) 
END 
ELSE 
IF (@Destination='C' OR @Destination='H') 
    BEGIN 
     if Exists (SELECT NULL from tblOpportunityDataSets where [email protected]) 
     BEGIN 
      SET @countCurrent=(SELECT COUNT(1) from tblOptyRecordsCurrent where [email protected]) 
      SET @countHistorical=(SELECT COUNT(1) from tblOptyRecordsHistorical where [email protected]) 
      IF @destination='C' 
      BEGIN 
       if @countCurrent>0 
       BEGIN 
        RAISERROR('There are already existing records in the Current Tables for the specified DataSet', 5, 1) 
       END ELSE 
       if @countHistorical=0 
       BEGIN 
        RAISERROR('There do not appear to be any records in the Historical Tables to transfer for the specified Dataset', 5, 1) 
       END ELSE 
       BEGIN 
        -- ENTER TRANSFER CODE 
        INSERT INTO tblRecordsHistorical 
        (X, Y, Z) 
        SELECT X, Y, Z FROM tblA 
        WHERE x=y 
        -- Check that record count in both tables match 
        SET @countCurrent=(SELECT COUNT(1) from tblOptyRecordsCurrent where [email protected]) 
        SET @countHistorical=(SELECT COUNT(1) from tblOptyRecordsHistorical where [email protected]) 
        IF (@countCurrent<>@countHistorical) 
        BEGIN 
         RAISERROR('There was an error whilst copying the records into the Historical Tables, Source and Destination Record Count do not match', 5, 1) 
        END ELSE 
        BEGIN 


        END 
       END 
      END ELSE 
      IF @Destination='H' 
      BEGIN 
       if @countHistorical>0 
       BEGIN 
        RAISERROR('There are already existing records in the Historical Tables for the specified DataSet', 5, 1) 
       END ELSE 
       if @countCurrent=0 
       BEGIN 
        RAISERROR('There do not appear to be any records in the Historical Tables to transfer for the specified Dataset', 5, 1) 
       END ELSE 
       BEGIN 
        RAISERROR('DataSet Found, ready to transfer records to HISTORICAL', 5, 1)  
        -- ENTER TRANSFER CODE 
        INSERT INTO tblOptyRecordsCurrent 
        (X, Y, Z) 
        SELECT X, Y, Z FROM tblB 
        WHERE x=y 
        -- Check that record count in both tables match 
        SET @countCurrent=(SELECT COUNT(1) from tblOptyRecordsCurrent where [email protected]) 
        SET @countHistorical=(SELECT COUNT(1) from tblOptyRecordsHistorical where DataSetID=[email protected]) 



       END 
      END 
     END 
     ELSE 
     BEGIN 
      RAISERROR('The DataSet you have specified cannot be found', 5, 1) 
     END 
    END 
    ELSE 
    BEGIN 
     RAISERROR('You have not specified a valid Destination', 5, 1) 
    END

注意，在包含INSERT INTO代码的两节中，将有至少两个额外的SQL操作声明必须全部运作或全都失败。

编辑：我已经与

BEGIN TRAN 
BEGIN TRY 
    -- STATEMENT 1 
    INSERT INTO X WHERE Y 
    -- STATEMENT 2 
    DELETE FROM X WHERE Y 
    -- STATEMENT 3 
    UPDATE X WHERE Y 
    COMMIT 
END TRY 
BEGIN CATCH 
    ROLLBACK TRAN 
    RAISERROR('There was an error whilst copying the records into the Current Tables. The Transaction has been rolled back', 5, 1) 
END CATCH
