I would like to know if it is possible to perform an SQL query and pass it a numerical parameter. Let's suppose that I have the following query:
SELECT
CONCAT(cuatrimestre,' Cuatrimestre') As quarter
, ROUND(SUM(fact_Ventas.cantidad * precioUnitario),0) as amount
FROM fact_Ventas
INNER JOIN dim_Tiempos ON
fact_Ventas.idAnio = dim_Tiempos.idAnio AND
fact_Ventas.idMes = dim_Tiempos.idMes AND
fact_Ventas.idDia = dim_Tiempos.idDia
INNER JOIN dim_Clientes ON dim_Clientes.idCliente = fact_Ventas.idCliente
INNER JOIN dim_Productos ON dim_Productos.idProducto = fact_Ventas.idProducto
WHERE
CAST(fact_Ventas.idAnio As Char) LIKE ${paramAnio} AND
CAST(fact_Ventas.idMes As Char) LIKE ${paramMes} AND
CAST(fact_Ventas.idVendedor As Char) LIKE ${paramVendedores} AND
CAST(fact_Ventas.origen As Char) LIKE ${paramOrigen} AND
dim_Productos.marca LIKE ${paramMarca} AND
dim_Clientes.segmentoCliente LIKE ${paramSegmento}
GROUP BY 1
ORDER BY 1
I want to divide the column amount, by a numerical value extracted from a simple parameter. I managed to use filters in the where clause, but I can not make a division in a column.
Try the following query:
SELECT
CONCAT(cuatrimestre,' Cuatrimestre') As cuatrimestre
, ROUND( (SUM(fact_Ventas.cantidad * precioUnitario)/${paramValue}),0) as Importe
FROM fact_Ventas
INNER JOIN dim_Tiempos ON
fact_Ventas.idAnio = dim_Tiempos.idAnio AND
fact_Ventas.idMes = dim_Tiempos.idMes AND
fact_Ventas.idDia = dim_Tiempos.idDia
INNER JOIN dim_Clientes ON dim_Clientes.idCliente = fact_Ventas.idCliente
INNER JOIN dim_Productos ON dim_Productos.idProducto = fact_Ventas.idProducto
WHERE
CAST(fact_Ventas.idAnio As Char) LIKE ${paramAnio} AND
CAST(fact_Ventas.idMes As Char) LIKE ${paramMes} AND
CAST(fact_Ventas.idVendedor As Char) LIKE ${paramVendedores} AND
CAST(fact_Ventas.origen As Char) LIKE ${paramOrigen} AND
dim_Productos.marca LIKE ${paramMarca} AND
dim_Clientes.segmentoCliente LIKE ${paramSegmento}
GROUP BY 1
ORDER BY 1
But it gives an error and the data is not loaded. The syntax of the query was tested in the database and is correct.
Did you set the parameter type to Numeric? It defaults to String which was probably fine for your other parameters.
The problem was that I forgot to assign the parameter to the component, I had associated it with SQL Query but not with the component.

I have a SQL query where I am trying to replace null results with zero. My code is producing an error
[1]: ORA-00923: FROM keyword not found where expected
I am using an Oracle Database.
Select service_sub_type_descr,
nvl('Single-occupancy',0) as 'Single-occupancy',
nvl('Multi-occupancy',0) as 'Multi-occupancy'
From
(select s.service_sub_type_descr as service_sub_type_descr, ch.claim_id,nvl(ci.item_paid_amt,0) as item_paid_amt
from table_1 ch, table_" ci, table_3 s, table_4 ppd
where ch.claim_id = ci.claim_id and ci.service_type_id = s.service_type_id
and ci.service_sub_type_id = s.service_sub_type_id and ch.policy_no = ppd.policy_no)
Pivot (
count(distinct claim_id), sum(item_paid_amt) as paid_amount For service_sub_type_descr IN ('Single-occupancy', 'Multi-occupancy')
)
This expression:
nvl('Single-occupancy',0) as 'Single-occupancy',
is using an Oracle bespoke function to say: If the value of the string Single-occupancy' is not null then return the number 0.
That logic doesn't really make sense. The string value is never null. And, the return value is sometimes a string and sometimes a number. This should generate a type-conversion error, because the first value cannot be converted to a number.
I think you intend:
coalesce("Single-occupancy", 0) as "Single-occupancy",
The double quotes are used to quote identifiers, so this refers to the column called Single-occupancy.
All that said, fix your data model. Don't have identifiers that need to be quoted. You might not have control in the source data but you definitely have control within your query:
coalesce("Single-occupancy", 0) as Single_occupancy,
EDIT:
Just write the query using conditional aggregation and proper JOINs:
select s.service_sub_type_descr, ch.claim_id,
sum(case when service_sub_type_descr = 'Single-occupancy' then item_paid_amt else 0 end) as single_occupancy,
sum(case when service_sub_type_descr = 'Multi-occupancy' then item_paid_amt else 0 end) as multi_occupancy
from table_1 ch join
table_" ci
on ch.claim_id = ci.claim_id join
table_3 s
on ci.service_type_id = s.service_type_id join
table_4 ppd
on ch.policy_no = ppd.policy_no
group by s.service_sub_type_descr, ch.claim_id;
Much simpler in my opinion.
for column aliases, you have to use double quotes !
don't use
as 'Single-occupancy'
but :
as "Single-occupancy",
I have a query like this
select
t.tiid, t.employeeid, t.remarks,
dd.DocID, dd.Document, dd.DocuName
from
ti t
inner join
History cth on cth.tiid = t.tiid
inner join
Downloads dd on dd.DocID = cth.DocID
My data in table is like this
History:
DocID DocuName
1,2 abc.dox,def.docx
Downloads
DocID DocuName document
1 abc.docx x3400000efg..
2 def.docx xc445560000...
but when I execute this query, it shows an error:
Conversion failed when converting the varchar value '1,2' to data type int.
The DocID of history is multiple DocID had been combined with comma, So you can not compare the value directly( One value vs Multiple values).
You can check whether the multiple values contain the specify value use CHARINDEX.
To make sure complete matched of sub string,need a delimiter to indicate a single value, otherwise can get wrong result.
For Eample:
CHARINDEX('1,','12,2,3') will be 1, but in fact, there is no 1 in the string.
select
t.tiid,
t.employeeid,
t.remarks,
dd.DocID,
dd.Document,
dd.DocuName
from ti t
inner join History cth on cth.tiid=t.tiid
inner join Downloads dd on CHARINDEX(','+LTRIM(dd.DocID)+',',','+cth.DocID+',')>0
As the error says, you are trying to equate a string with int.You need to convert the int DocID as string and check if it's present in the comma-separated DocID .Something like
SELECT t.tiid,
t.employeeid,
t.remarks,
dd.DocID,
dd.Document,
dd.DocuName
FROM ti t
INNER JOIN History cth ON cth.tiid=t.tiid
INNER JOIN Downloads dd ON CHARINDEX(',' + CAST(dd.DocID AS VARCHAR(10)) + ',',',' + cth.DocID + ',')>0
This is driving me crazy. I want to do simple comparison of a column and a variable but it just doesn't work. The QUERY 1 in following code returns me my value when i do a simple select, but i use the resulting variable in my 2nd query it just doesn't work..
It looks sooooo simple but I've been working on this for hours. The complete sql proc is
The big confusing thing is that if I replace v_bbg_symbol with some hard coded 'Value' (like 'FEDL01') it gives a correct answer for Query 2, but when I use the variable v_bbg_symbol it just doesn't work any more
Declare
v_bbg_symbol VARCHAR2(50);
V_OLD_INS_NAME Varchar2(50);
Begin
--QUERY 1
SELECT BBG_SYMBOL into v_bbg_symbol FROM quotes_external WHERE ID = 1;
--Gives output - 'FEDL01'
DBMS_OUTPUT.PUT_LINE('I got here:'||v_bbg_symbol||' is my value');
-QUERY 2
SELECT NAME INTO V_OLD_INS_NAME FROM INSTRUMENT
JOIN CURVE_INSTRUMENT ON
INSTRUMENT.INSTRUMENT_ID = CURVE_INSTRUMENT.INSTRUMENT_ID
JOIN GENERIC_INSTRUMENT ON
CURVE_INSTRUMENT.GENERIC_INSTRUMENT_ID = GENERIC_INSTRUMENT.GENERIC_INSTRUMENT_ID
WHERE CURVE_INSTRUMENT.CURVE_SNAPSHOT_ID =
(SELECT MAX(CURVE_INSTRUMENT.CURVE_SNAPSHOT_ID) FROM CURVE_INSTRUMENT)
AND GENERIC_INSTRUMENT.INSTRUMENT_NAME = v_bbg_symbol;
--ORACLE ERROR 'No Data Found'
DBMS_OUTPUT.PUT_LINE('I got here:'||V_OLD_INS_NAME||' is the new value');
END;
The first 'SELECT' gives me value which i select INTO a variable 'v_bbg_symbol', but when I use the same variable 'v_bbg_symbol' in my 2nd QUERY it pretends as if there is no value passed and does not return any result. If I give static value of 'v_bbg_symbol' i.e. ('FEDL01' in this case) in my 2nd QUERY, the results come as expected.
Please help..
Here is your query, with table aliases to facilitate following it:
SELECT NAME INTO V_OLD_INS_NAME
FROM INSTRUMENT i JOIN
CURVE_INSTRUMENT ci
ON i.INSTRUMENT_ID = ci.INSTRUMENT_ID JOIN
GENERIC_INSTRUMENT gi
ON ci.GENERIC_INSTRUMENT_ID = gi.GENERIC_INSTRUMENT_ID
WHERE ci.CURVE_SNAPSHOT_ID = (SELECT MAX(ci.CURVE_SNAPSHOT_ID) FROM CURVE_INSTRUMENT ci) and
gi.INSTRUMENT_NAME = v_bbg_symbol;
What this says is that the maximum ci.curve_snapshot_id is not for the instrument that is associated with v_bbg_symbol. I think you want a correlated subquery:
SELECT NAME INTO V_OLD_INS_NAME
FROM INSTRUMENT i JOIN
CURVE_INSTRUMENT ci
ON i.INSTRUMENT_ID = ci.INSTRUMENT_ID JOIN
GENERIC_INSTRUMENT gi
ON ci.GENERIC_INSTRUMENT_ID = gi.GENERIC_INSTRUMENT_ID
WHERE ci.CURVE_SNAPSHOT_ID = (SELECT MAX(ci2.CURVE_SNAPSHOT_ID)
FROM CURVE_INSTRUMENT ci2
WHERE ci2.instrument_id = i.instrument_id
) and
gi.INSTRUMENT_NAME = v_bbg_symbol;
I have one master table with all the IDs to each child table. The SQL statement looks like this...
SELECT Class.Descript
, Regulation.Descript AS Reg
, Compgroup.Descript AS Grouping
, Category.Descript AS Cat
, Exempt.Descript AS Exempt
, Reason.Descript AS Reasons
, COALESCE(ComponentRuleSet.NormalType, ComponentRuleSet.Supertype, '') AS Type
FROM ComponentRuleSet
LEFT OUTER JOIN Reason
ON ComponentRuleSet.ComponentCategoryID = Reason.ComponentCategoryID
LEFT OUTER JOIN Class
ON ComponentRuleSet.ComponentClassID = Class.ComponentClassID
LEFT OUTER JOIN Regulation
ON ComponentRuleSet.RegulationID = Regulation.RegulationID
LEFT OUTER JOIN Compgroup
ON ComponentRuleSet.ComplianceGroupID = Compgroup.ComplianceGroupID
LEFT OUTER JOIN Category
ON ComponentRuleSet.ComponentCategoryID = Category.ComponentCategoryId
LEFT OUTER JOIN Exempt
ON ComponentRuleSet.ExemptID = Exempt.ComponentExemptionID
WHERE (ComponentRuleSet.ComponentID = 38048)
The problem is that there are two fields in the ComponentRuleSet table called NormalType and Supertype. If either of those fields have a value, I need to display it in a column called Type. Yet, if neither have a value I need to display a Blank value in the Type column.
Any ideas?
---EDIT
Is my placement of COALESCE correct in the edited query? It is still returning errors.
--UPDATE
IMPORTANT: The type of both fields are boolean, I need to return the column name of the column that holds a TRUE value, and place that value in the TYPE column.
Use COALESCE for this field:
COALESCE(ComponentRuleSet.NormalType, ComponentRuleSet.Supertype, '') AS Type
COALESCE:
Returns the first nonnull expression among its arguments.
Following your comments as to the actual requirement, CASE is probably a better option:
CASE WHEN ComponentRuleSet.NormalType = 1 THEN 'NormalType'
WHEN ComponentRuleSet.Supertype = 1 THEN 'SuperType'
ELSE ''
END AS Type
Seeing your comments, perhaps a CASE expression will work:
select ...
, CASE WHEN ComponentRuleSet.NormalType is not null then 'NormalType'
WHEN ComponentRuleSet.Supertype is not null then 'SuperType'
ELSE ''
end as Type
UPDATE Since boolean values are just 1 for true and 0 for false, try this:
select ...
, CASE WHEN ComponentRuleSet.NormalType = 1 then 'NormalType'
WHEN ComponentRuleSet.Supertype = 1 then 'SuperType'
ELSE ''
end as Type
This is the only place that I get all answer ;)
I want to select :
SELECT
RTRIM(LTRIM(il.Num_bloc)) AS Bloc,
RTRIM(LTRIM(il.num_colis)) AS Colis,
cd.transporteur AS Coursier,
cd.origine AS Origine,
cd.destination AS Destinataire,
cd.adresse AS [Adresse Destinataire],
cd.poids AS Poids,
il.Signataire, il.num_cin AS CIN, il.date_livraison AS [Date Livraison]
FROM
dbo.cd
INNER JOIN
dbo.il ON cd.bloc = il.Num_bloc AND dbo.cd.colis = dbo.il.num_colis
WHERE
(il.Num_bloc = RTRIM(LTRIM(#ParamBloc)))
AND (il.num_colis = RTRIM(LTRIM(#ParamColis)))
In the way of getting result if the user put ether #ParamBloc or #ParamColis
Try using IsNull() function.
A simple query would go like this
Select * from yourTable
Where
Num_bloc = ISNULL(#ParamBloc, Num_block) AND
num_colis = ISNULL(#ParamColis, num_colis)
The second parameter would make the expression to true if the #parameter Bloc or Colis is null. This query would be useful for all 4 possible combination of these two parameter.
