I'm looking at doing some report development for one of our Training softwares. I finally got some queries working in FB Maestro, as I'm only familiar with SQL and Oracle.
I have the following query that works and returns results, but when trying to set up a parameter for the display name, the query runs (at least it returns no errors) however the dataset does not return any data. Has anyone worked with these before?
Here's the query:
Select CertStatus, DisplayName, Count(CertStatus) From ( With cte as (Select * From (Select COURSEVERSIONSWITHAGGREGATES.CourseTitle, COURSEVERSIONSWITHAGGREGATES.CourseNumber, "MaxTrainedCompletionDate", "Course_ID", PersonnelView.DISPLAYNAME, COURSEVERSIONSWITHAGGREGATES.RecertificationValue, COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID,
CASE
WHEN COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID = 3 THEN DATEADD(year, 1*COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONVALUE, MaxTrainingView."MaxTrainedCompletionDate")
WHEN COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID = 2 THEN DATEADD(month, 1*COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONVALUE, MaxTrainingView."MaxTrainedCompletionDate")
WHEN COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID = 1 THEN DATEADD(week, 1*COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONVALUE, MaxTrainingView."MaxTrainedCompletionDate")
WHEN COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONUNIT_ID = 0 THEN DATEADD(day, 1*COURSEVERSIONSWITHAGGREGATES.RECERTIFICATIONVALUE, MaxTrainingView."MaxTrainedCompletionDate") END
AS ExpirationDate
From MAXTRAININGVIEW
INNER JOIN PERSONNELVIEW ON (MAXTRAININGVIEW."Personnel_ID" = PERSONNELVIEW.PERSONNELID) INNER JOIN COURSEVERSIONSWITHAGGREGATES ON (MAXTRAININGVIEW."Course_ID" = COURSEVERSIONSWITHAGGREGATES.COURSEID)
WHERE Personnelview.DisplayName = 'Aaron')) Select CourseTitle, CourseNumber, "MaxTrainedCompletionDate", "Course_ID", DisplayName, RecertificationValue, Recertificationunit_ID, ExpirationDate,
CASE WHEN ExpirationDate > current_date Then 'Active' WHEN ExpirationDate < current_date Then 'Expired' END As CertStatus from cte) Group By CertStatus, DisplayName
This returns values with the static value of 'Aaron' in report builder. But trying to use a parameter, it does not throw an error in report builder, however it just does not return any data.
For example this:
WHERE Personnelview.DisplayName = '#DisplayName'))
I've got the parameter based off another data set query, and that seems to work (it gives me the option to select employees)
Here is an example of it passing 'Aaron' (with personal info removed)
Example of passing #FName Parameter:
If you want to pass the parameter in report, other type database might not recognize query like "where [field] in #parameter", so I think you could try to use filter to achieve this goal(create a filter in dataset, and create a parameter, then specify it in filter properties).

I have a complex SQL query where I have a few cases that use END AS variableName. I then use variableName to do some logic and then create a new variable which I want in the output result. However when I run the query, all the END AS variableNames that I have used are also outputted in the results.
Is there a way that I can exclude these variables as I only want the final variable that uses these variableNames.
Thanks
EDIT, here is a query explaining my problem
SELECT DISTINCT
mt.src_id AS “SRC_ID”,
CASE
WHEN mt.cd = ‘TAN’ THEN
(
(
SELECT SUM(src_amt)
FROM source_table st
WHERE mt.id = st.id
AND st._cd = ‘TAN’
AND st.amt_cd = ‘ABL’)
)
END AS src_amt
FROM MAIN_TABLE mt
WHERE
mf.dt >= 2021-12-12
AND SRC_AMT > 10
I need SRC_AMT to be used as some sort of logic but when I run the query, it prints out in the output as it's own column. I want to ignore this variable
you can wrap the whole thing into a new select-statement:
select SRC_ID from ( <entire previous query here> )
I have a SQL statement on Netezza that uses the following SQL to acquire the currently logged on user ID:
SELECT SESSION_USERNAME FROM _V_SESSION_DETAIL WHERE SESSION_ID=current_sid
This works great when I'm executing the SQL in a database client. However, when I implement the above SQL in a view (along with other SQL) the current_sid is replaced with the session ID I happened to have when I created the view. That SQL will then look something like:
SELECT DEFINITION_SCHEMA."_V_SESSION_DETAIL".SESSION_USERNAME FROM DEFINITION_SCHEMA."_V_SESSION_DETAIL" WHERE (DEFINITION_SCHEMA."_V_SESSION_DETAIL".SESSION_ID = 2434740
Is there a way to define a view that will get the currently logged on user's ID, not the ID that was assigned when the view was created?
Seems like Netezza Metadata functions(ex. current_sid) are not supported in with clause and would advice to remove them from with and to include them in the base query .
CREATE
OR REPLACE VIEW ADMIN.VW_PI_HRCHY_EPH AS
WITH CHAR_MASK(CHAR_MASK_CHAR) AS (
SELECT 'xxx'
FROM _V_SESSION_DETAIL LIMIT 1
)
,NUM_MASK(NUM_MASK_NUM) AS (
SELECT - 1
FROM _V_SESSION_DETAIL LIMIT 1
)
,TS_MASK(TS_MASK_TS) AS (
SELECT '1000-01-01 00:00:00'
FROM _V_SESSION_DETAIL LIMIT 1
)
SELECT CASE
WHEN SECURITY_GRP_CNT.COUNT > 0
THEN PI_HRCHY.HRCHY_LINE_ID
ELSE NUM_MASK.NUM_MASK_NUM
END AS HRCHY_LINE_ID
,CASE
WHEN SECURITY_GRP_CNT.COUNT > 0
THEN PI_HRCHY.LOCALE_CD
ELSE CHAR_MASK.CHAR_MASK_CHAR
END AS LOCALE_CD
,CASE
WHEN SECURITY_GRP_CNT.COUNT > 0
THEN PI_HRCHY.MODIFY_TS
ELSE TS_MASK.TS_MASK_TS
END AS MODIFY_TS
FROM (
SELECT COUNT(*) AS count
FROM _V_USERGROUPS
WHERE USERNAME IN (
SELECT SESSION_USERNAME
FROM _V_SESSION_DETAIL
WHERE SESSION_ID = current_sid
)
AND GROUPNAME = 'GROUP_AUTH2READ'
) SECURITY_GRP_CNT
,ADMIN.PI_HRCHY
,CHAR_MASK
,NUM_MASK
,TS_MASK
WHERE (
(PI_HRCHY.HRCHY_TYP_ID = 11)
AND (PI_HRCHY.ACTV_IND = 'Y'::"NCHAR")
);
The solution NzGuy provided solved my problem. As he stated, apparently placing the current_sid contact in the WITH clause of the SQL causes the constant to be evaluated differently than if it were placed outside the WITH. The common table expression defined outside the WITH clause resolved my problem.
I'm having a Sql code like as follows
Select a.ItemCode, a.ItemDesc
From fn_BOM_Material_Master('A', #AsOnDate, #RptDate, #BranchID, #CompID)a
Left Outer Join fn_INV_AsOnDate_Stock(#StockDate, #AsOnDate, #RptDate, #BranchID, #CompID, #Finyear)b
On a.ItemCode=b.ItemCode and b.WarehouseCode<>'WAP'
and a.BranchID=b.BranchID and a.CompID=b.COmpID
Where a.ItemNatureCode = 'F' and a.BranchID = #BranchID and a.CompID = #CompID
Group by a.ItemCode, a.ItemDesc
Having sum(b.CBQty)<=0
Here the problem is that im passing an "#ShowZeroStock" value as as bit if the "#ShowZeroStock" value is '1' then Having should not be validated or (i.e: All values from the table should be returned including zero)
So How to change the query based on passed bit value "#ShowZeroStock"
I can Use "If else " condition at the top and remove having in else part, but for a lengthy query i can't do the same.
Is this the logic you want?
Having sum(b.CBQty) <= 0 or #ShowZeroStock = 1
Good morning everyone!
Below is a piece of code I stitched together: I used a CTE to grab the records(data) from a link table and than convert strings to dates, than use the merge statement to get the data into a local table:
I am having a problem with the column(field) LAST_RACE_DATE this field is set to NULL and is not required but it does not update with my current set up. What I am trying to accomplished is for this field to populate when data is entered but also update, meaning it should also update with NULL.
So if the field has a specific date, and a new date is entered in the remote database, this field should update as well, even if the data is deleted in the back end, it should also remove the local table data for this field.
WITH CTE AS(
SELECT MEMBER_ID
,[MEMBER_DATE] = MAX(CONVERT(DATE, MEMBER_DATE))
,RACE_DATE = MAX(CONVERT(DATE, RACE_DATE))
,LAST_RACE_DATE = MAX(CONVERT(DATE, LAST_RACE_DATE))
FROM [EXAMPLE].[dbo].[LINKED_MEMBER_DATA]
WHERE (MEMBER_DATE IS NOT NULL) AND (ISDATE(MEMBER_DATE)<> 0) AND (RACE_DATE IS NOT NULL) AND (ISDATE(RACE_DATE)<> 0)
AND (LAST_RACE_DATE IS NULL) OR (ISDATE(LAST_RACE_DATE)<> 0)
GROUP BY MEMBER_ID)
MERGE dbo.LINKED_MEMBER_DATA AS Target
USING (SELECT
MEMBER_ID, MEMBER_DATE, RACE_DATE, LAST_RACE_DATE
FROM CTE
GROUP BY MEMBER_ID, RACE_DATE, LAST_RACE_DATE)AS SOURCE ON (Target.MEMBER_ID = SOURCE.MEMBER_ID)
WHEN MATCHED AND
(Target.MEMBER_DATE) <> (SOURCE.MEMBER_DATE)
OR (Target.RACE_DATE) <> (SOURCE.RACE_DATE)
OR ISNULL(TARGET.LAST_RACE_DATE , Target.LAST_RACE_DATE) <> ISNULL(SOURCE.LAST_RACE_DATE, SOURCE.LAST_RACE_DATE)
THEN UPDATE SET
Target.MEMBER_DATE = SOURCE.MEMBER_DATE
,Target.RACE_DATE = SOURCE.RACE_DATE
,Target.LAST_RACE_DATE = SOURCE.LAST_RACE_DATE
WHEN NOT MATCHED BY TARGET THEN
INSERT(
MEMBER_ID, MEMBER_DATE, RACE_DATE, LAST_RACE_DATE)
VALUES (Source.MEMBER_ID, Source.MEMBER_DATE, Source.RACE_DATE, Source.LAST_RACE_DATE);
I also tried this:
ISNULL(Target.LAST_RACE_DATE,'N/A') <> ISNULL(SOURCE.LAST_RACE_DATE,'N/A')
But it generates the below error for dates conversion:
Conversion failed when converting date and/or time from character string.
Thanks a Million!!
Your current statement is failing because the ISNULLs that you have don't do anything (if one of the values is NULL the expression will evaluate to NULL), and NULL values don't compare. Your second attempt doesn't work because ISNULL requires the data types of the two values to be the same, so you could try eg ISNULL(Target.LAST_RACE_DATE, '1970-01-01') <> ISNULL(Source.LAST_RACE_DATE, '1970-01-01').
Another option would be to simply enumerate the different cases (eg, (((Source.LAST_RACE_DATE IS NULL AND Target.LAST_RACE_DATE IS NOT NULL) OR (Source.LAST_RACE_DATE IS NOT NULL AND Target.LAST_RACE_DATE IS NULL) OR (Source.LAST_RACE_DATE <> Target.LAST_RACE_DATE))). Enumerating the different situations makes the code a bit more verbose, but it can result in better performance (whether it is measurably better really depends on how much data you are processing).
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.
