I run the procedure in SMSS and @a1 to @a24 and @b1 to @b24 are not null and result is integer. However, the @resultTOT1 to @resultTOT24 is returning 0. I can't figure out why, please help.

Prasad Raveendran · Answer

ssues: Integer Division Truncation: Since @sumA and @sumB are integers, the division result is also an integer, losing decimal precision before converting to DECIMAL(6,2) . Fix: Convert at least one operand to DECIMAL(6,2) before division: ???????SET @currentResultTOT = CONVERT(DECIMAL(6,2), @sumA) / NULLIF(@sumB, 0); Why NULLIF(@sumB, 0) ? This prevents division by zero. Repeated Accumulation in Loop: Each iteration keeps adding values to @sumA and @sumB , leading to incorrect cumulative calculations. Fix: Compute only the individual division at each iteration instead of cumulative sums: ???????SET @currentResultTOT = CONVERT(DECIMAL(6,2), CASE @counter WHEN 1 THEN @a1 / NULLIF(@b1, 0) WHEN 2 THEN @a2 / NULLIF(@b2, 0) WHEN 3 THEN @a3 / NULLIF(@b3, 0) WHEN 4 THEN @a4 / NULLIF(@b4, 0) WHEN 5 THEN @a5 / NULLIF(@b5, 0) WHEN 6 THEN @a6 / NULLIF(@b6, 0) WHEN 7 THEN @a7 / NULLIF(@b7, 0) WHEN 8 THEN @a8 / NULLIF(@b8, 0) WHEN 9 THEN @a9 / NULLIF(@b9, 0) WHEN 10 THEN @a10 / NULLIF(@b10, 0) WHEN 11 THEN @a11 / NULLIF(@b11, 0) WHEN 12 THEN @a12 / NULLIF(@b12, 0) WHEN 13 THEN @a13 / NULLIF(@b13, 0) WHEN 14 THEN @a14 / NULLIF(@b14, 0) WHEN 15 THEN @a15 / NULLIF(@b15, 0) WHEN 16 THEN @a16 / NULLIF(@b16, 0) WHEN 17 THEN @a17 / NULLIF(@b17, 0) WHEN 18 THEN @a18 / NULLIF(@b18, 0) WHEN 19 THEN @a19 / NULLIF(@b19, 0) WHEN 20 THEN @a20 / NULLIF(@b20, 0) WHEN 21 THEN @a21 / NULLIF(@b21, 0) WHEN 22 THEN @a22 / NULLIF(@b22, 0) WHEN 23 THEN @a23 / NULLIF(@b23, 0) WHEN 24 THEN @a24 / NULLIF(@b24, 0) END ); Better Alternative - Using a Table Variable: Instead of many variables and CASE statements, a table variable simplifies the logic: DECLARE @Data TABLE ( RowNum INT PRIMARY KEY, A INT, B INT, Result DECIMAL(6,2) ); -- Insert all values into the table INSERT INTO @Data (RowNum, A, B) VALUES (1,4,1), (2,3,2), (3,4,1), (4,4,2), (5,0,0), (6,3,1), (7,0,0), (8,2,1), (9,1,0), (10,2,1), (11,4,1), (12,3,4), (13,6,2), (14,5,1), (15,3,0), (16,3,2), (17,9,8), (18,6,3), (19,6,3), (20,4,2), (21,0,0), (22,2,1), (23,6,3), (24,9,4); -- Compute results UPDATE @Data SET Result = CONVERT(DECIMAL(6,2), A) / NULLIF(B, 0); -- Return results SELECT * FROM @Data; This approach makes it much easier to manage and debug!

Please help!!!

It seems that the issue causing @resultTOT1 to @resultTOT24 to return 0 in your SQL Server procedure lies within the aggregation logic and variable assignments. Here are some aspects to consider in troubleshooting this problem: 1. Debugging the Calculation : - Verify that your calculation for `@currentResultTOT` is correctly computing the result. Check if the values of `@sumATOT` and `@sumTOT` are being computed accurately to ensure the division yields the expected outcome. You can use `PRINT` or `SELECT` statements within the loop to inspect these intermediate values. 2. Data Availability : - Double-check the data retrieved by queries assigning values to variables like @a1 to @a24 and @b1 to @b24. Ensure that the queries are fetching the necessary data and that there are no conditions causing unexpected results, such as missing data or incorrect join conditions. 3. Month-Handling : - Review the logic concerning month calculations, particularly how you are handling month offsets and ensuring that the correct months are considered in your date calculations. An error in month calculation could lead to unexpected results. 4. Data Types and Conversions : - Confirm that the data types used in computations and assignments align with the expected result types. Check whether any implicit conversions may be altering the results unintentionally. 5. Scope and Visibility : - Ensure that the variables are correctly scoped throughout the procedure. Variables declared outside the loop should retain their values as intended, and the calculations should accumulate properly. 6. Error Handling : - Implement error handling within your stored procedure to catch any potential issues that might be occurring during data retrieval or calculations. This can help in identifying and addressing issues promptly. By thoroughly reviewing these aspects and potentially adding some diagnostic messages within the stored procedure to output intermediate results, you can pinpoint the root cause of why @resultTOT1 to @resultTOT24 is returning 0. Once you identify the specific stage where the unexpected behavior occurs, it will be easier to refine the procedure and correct the issue. Let me know if you need further assistance or more specific guidance on any of these points!
