Preciso converte o codigo abaixo para PL/SQl, ele esta em T-SQL do SQL Server funciona que é uma maravilha, é uma procedure generica para montar estatistica, tipo cubo de decisao.
Se alguém puder ajudar.
Código: Selecionar todos
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[spDynamicCrossTab]

@RowValue VARCHAR(255), --what is the SQL for the row title
@ColValue VARCHAR(255), --what is the SQL for the column title
@Aggregate VARCHAR(255), --the aggregation value to go in the cells
@FromExpression VARCHAR(8000), --the FROM, ON and WHERE clause
@colOrderValue VARCHAR (255)=NULL, --how the columns are ordered
@Title VARCHAR(80)='_', --the title to put in the first col of first row
@SortBy VARCHAR(255)='row asc', --what you sort the rows by (column heading)
@RowSort VARCHAR(80)=NULL,
@ReturnTheDDL INT=0,--return the SQL code rather than execute it
@Debugging INT=0 --debugging mode
/*
e.g.
Execute spDynamicCrossTab
@RowValue='firstname+'' ''+lastname',
@ColValue='Year(OrderDate)',
@Aggregate= 'count(*)',
@FromExpression='FROM Employees INNER JOIN Orders
ON (Employees.EmployeeID=Orders.EmployeeID)',
@ColOrderValue='Year(OrderDate)',
@Title ='No. Sales per year',
@SortBy ='total desc' --what you sort the rows by (column heading)

Execute spDynamicCrossTab
@RowValue='firstname+'' ''+lastname',
@ColValue='DATENAME(month,orderDate)',
@Aggregate= 'sum(subtotal)',
@FromExpression='FROM Orders
INNER JOIN "Order Subtotals"
ON Orders.OrderID = "Order Subtotals".OrderID
inner join employees on employees.EmployeeID =orders.EmployeeID',
@ColOrderValue='datepart(month,orderDate)',
@Title ='Customers orders per month '

EXECUTE spDynamicCrossTab
@RowValue='country',
@ColValue='datename(quarter,orderdate)
+case datepart(quarter,orderdate)
when 1 then ''st''
when 2 then ''nd''
when 3 then ''rd''
when 4 then ''th'' end',
@Aggregate= 'sum(subtotal)',
@FromExpression='FROM Orders
INNER JOIN "Order Subtotals"
ON Orders.OrderID = "Order Subtotals".OrderID
inner join customers on customers.customerID =orders.customerID',
@ColOrderValue='datepart(quarter,orderDate)',
@sortby='total desc',
@Title ='value of orders per quarter'

*/
AS
SET nocount ON
DECLARE @Command NVARCHAR(MAX)
DECLARE @SQL VARCHAR(MAX)
DECLARE @SQL1 VARCHAR(MAX)

--make sure we have sensible defaults for orders
SELECT @ColOrderValue=COALESCE(@ColOrderValue, @ColValue),
@Sortby=COALESCE(@SortBy,@RowValue),
@rowsort=COALESCE(@RowSort,@RowValue)



--first construct tha SQL which is used to calculate the columns in a
--string
SELECT @Command='select @SQL=coalesce(@SQL,''SELECT
['+@Title+']=case when row is null then ''''Sum''''
else convert(Varchar(80),[row]) end ,
'')+
''[''+convert(varchar(100),'
+@ColValue+')+''] =sum( CASE col WHEN ''''''+convert(varchar(100),'
+@ColValue+')+'''''' THEN data else 0 END ),
'' '+@FromExpression+'
GROUP BY '+@ColValue+'
order by max('+@ColorderValue+')'




--Now we execute the string to obtain the SQL that we will use for the
--crosstab query
EXECUTE sp_ExecuteSQL @command,N'@SQL VARCHAR(MAX) OUTPUT',@SQL OUTPUT
IF @@error > 0 --display the string if there is an error
BEGIN
RAISERROR ( 'offending code was ...%s', 0, 1, @command )
RETURN 1
END
IF @debugging <>0 SELECT @Command
--we now add the rest of the SQL into the string



SELECT @SQL=@SQL+' [Total]= sum( data )
from
(select [row]='+@RowValue+',
[col]='+@ColValue+',
[data]='+@Aggregate+',
[sort]=max('+@rowsort+')
'+@FromExpression+'
GROUP BY '+@RowValue+', '+@ColValue+'
)f
group by row with rollup
order by grouping(row),'+@Sortby

--and execute it
IF @ReturnTheDDL<>0 SELECT @SQL ELSE EXECUTE (@SQL)
IF @@error > 0
BEGIN
RAISERROR ( 'offending code was ...%s', 0, 1, @sql )
RETURN 1
END


A parte negritada é o principal problema
