MySQL SQL 创建具有列和行总计的临时表

Question

我正在使用支持许多 VB6 客户端的 MySQL 5.0 服务器。需要创建一个非常简单的应用程序来输出几个关键表的总数。无论如何，我都不是 SQL 专家，但我似乎遇到了各种错误。

目标是创建一个临时表，其中包含来自数据库中各种表的聚合。每行需要一个Total 列（在右侧），每列需要在底部行总计。

期望的输出：

         Account      Debit        Credit       Total
1        350          1000.94      0            -1000.94
2        103          0            551.34       551.34
3        356          0            10200.41     10200.41
...
14       000          1000.94      10751.75     9750.81

当前 MySQL SQL 适用于总计行，但无法弄清楚如何创建总计行（上面的#14）：

SET @PCName := "REPORTS";

Create temporary table TempTable( Account int, Debit int, Credit int, Total int);
(
SELECT * FROM (
    SELECT 1 as seq, '350' as Account, COALESCE(SUM(invoice_amount),0) as Debit, 0 as Credit, COALESCE(SUM(invoice_amount),0) * -1 as Total FROM invoice WHERE Voided = 0
    Union all
    SELECT 2 as seq, '103' as Account, 0 as Debit, COALESCE(SUM(check_amount),0) as Credit, COALESCE(SUM(check_amount),0) as Total FROM auctiondbh.Checks
    Union all
    SELECT 3 as seq, '356' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'BFC'
    Union all
    SELECT 4 as seq, '554' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'FEED' AND Description = 'Total Feed'
    Union all
    SELECT 5 as seq, '505' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'TOT_COMM'
    Union all
    SELECT 6 as seq, '525' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'CUSTOM_CHARGES' AND  description = 'Commingle%'
    -- ONE ATTEMPT FOLLOWS:
    -- union all
    -- select 14 as seq, '000' as Account, (SELECT SUM(Debit)) AS Debit, (SELECT SUM(Credit)) AS Credit, ((SELECT SUM(Debit)) - (SELECT SUM(Credit))) AS Total
    ) x
);
-- ANOTHER ATTEMPT FOLLOWS:
-- select * FROM TempTable
-- union all
-- select 14 as seq, '000' as Account, (SELECT SUM(debit)) AS Debit, (SELECT SUM(credit)) AS Credit, ((SELECT SUM(debit)) - (SELECT SUM(credit))) AS Total from TempTable

如何修复此 SQL 以创建包含借方、贷方和总计列总计的第 14 行？

Answer 1

您必须重复所有 13 次计算才能计算总数：

SET @PCName := "REPORTS";

Create temporary table TempTable( Account int, Debit int, Credit int, Total int);
(
SELECT * FROM (
    SELECT 1 as seq, '350' as Account, COALESCE(SUM(invoice_amount),0) as Debit, 0 as Credit, COALESCE(SUM(invoice_amount),0) * -1 as Total FROM invoice WHERE Voided = 0
    Union all
    SELECT 2 as seq, '103' as Account, 0 as Debit, COALESCE(SUM(check_amount),0) as Credit, COALESCE(SUM(check_amount),0) as Total FROM auctiondbh.Checks
    Union all
    SELECT 3 as seq, '356' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'BFC'
    Union all
    SELECT 4 as seq, '554' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'FEED' AND Description = 'Total Feed'
    Union all
    SELECT 5 as seq, '505' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'TOT_COMM'
    Union all
    SELECT 6 as seq, '525' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'CUSTOM_CHARGES' AND  description = 'Commingle%'
    union all
    select 14 as seq, '000' as Account, SUM(Debit) AS Debit, SUM(Credit) AS Credit, SUM(Debit - Credit) AS Total FROM
    (
    SELECT 1 as seq, '350' as Account, COALESCE(SUM(invoice_amount),0) as Debit, 0 as Credit, COALESCE(SUM(invoice_amount),0) * -1 as Total FROM invoice WHERE Voided = 0
    Union all
    SELECT 2 as seq, '103' as Account, 0 as Debit, COALESCE(SUM(check_amount),0) as Credit, COALESCE(SUM(check_amount),0) as Total FROM auctiondbh.Checks
    Union all
    SELECT 3 as seq, '356' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'BFC'
    Union all
    SELECT 4 as seq, '554' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'FEED' AND Description = 'Total Feed'
    Union all
    SELECT 5 as seq, '505' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'TOT_COMM'
    Union all
    SELECT 6 as seq, '525' as Account, 0 as Debit, COALESCE(SUM(Amount),0) as Credit, COALESCE(SUM(Amount),0) as Total FROM ScratchBal WHERE rec_Owner = @PCName AND RowType = 'CUSTOM_CHARGES' AND  description = 'Commingle%'
    ) w
  ) x
);
