I have an input db2 table with two elements: loan_number, debt_to_income; this table's name is #Input_Table. I am trying to run a test the function by running a SQL program against this table. The problem is that the function's element is not being recognized in the SQL program for some reason, maybe I have been looking at to long? I need to validate that the output in the table will output in a order by the debt_to_income field.
Here is the function code:
ALTER FUNCTION [dbo].[FN_DTI_BANDS]
(
-- the parameters for the function here
#FN_DTI_Band decimal(4,3)
)
RETURNS varchar(16)
AS
BEGIN
declare #Return varchar(16)
select #Return =
Case
when #FN_DTI_Band is NULL then ' Missing'
WHEN #FN_DTI_Band = 00.00 then ' Missing'
When #FN_DTI_Band < = 0.31 then 'Invalid'
When #FN_DTI_Band between 0.31 and 0.34 then '31-34'
When #FN_DTI_Band between 0.34 and 0.38 then '34-38'
When #FN_DTI_Band >= 0.38 then '38+'
else null end
-- Return the result of the function
RETURN #Return
END
Here is the T-SQL test program:
SELECT loan_number,dbo.FN_DTI_BANDS(debt_to_income)as FN_DTI_Band
from #Input_table
SELECT COUNT(*), FN_DTI_Band
FROM #Input_table
GROUP BY FN_DTI_Band
ORDER BY FN_DTI_Band
Here is the error:
Msg 207, Level 16, State 1, Line 7
Invalid column name 'FN_DTI_Band'.
Msg 207, Level 16, State 1, Line 5
Invalid column name 'FN_DTI_Band'.
Can someone help me spot what I am overlooking? Thank you!
the table #input_table does not have a column called FN_DTI_Band.
Just the result of the first select statement has that column name.
You need to make the first select statement a sub query of the 2nd
Something like this:
SELECT COUNT(*), T.FN_DTI_Band
FROM
(
SELECT loan_number,dbo.FN_DTI_BANDS(debt_to_income) as FN_DTI_Band
from #Input_table
) T
GROUP BY T.FN_DTI_Band
ORDER BY T.FN_DTI_Band
Try prepending "dbo" onto the name of the function.
Select Count(*), dbo.FN_DTI_Band

I want to do a count(*) of the number of a rows fom a DB2 database.
The basic query is the following:
select
SUBSTR("Request_Detail",LOCATE('/',"Request_Detail")+1,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)-LOCATE('/',"Request_Detail"))
from "Request_Analisys"
WHERE
"Sample_Date_and_Time">=1200323230000000 and "Sample_Date_and_Time"<1200332300000000
and "Request_Detail" <> '[Summary]'
and "Request_Detail" not like 'WS:%'
Now I'd like to do a count(*) of the resulting rows, but if I do a query like this:
select
count(*),
SUBSTR("Request_Detail",LOCATE('/',"Request_Detail")+1,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)-LOCATE('/',"Request_Detail"))
from "Request_Analisys"
WHERE
"Sample_Date_and_Time">=1200323230000000 and "Sample_Date_and_Time"<1200332300000000
and "Request_Detail" <> '[Summary]'
and "Request_Detail" not like 'WS:%'
It gives the error:
18:51:58 FAILED [SELECT - 0 rows, 0.032 secs] 1) [Code: -119, SQL State: 42803] An expression starting with "Request_Detail" specified in a SELECT clause, HAVING clause, or ORDER BY clause is not specified in the GROUP BY clause or it is in a SELECT clause, HAVING clause, or ORDER BY clause with a column function and no GROUP BY clause is specified.. SQLCODE=-119, SQLSTATE=42803, DRIVER=4.22.29
2) [Code: -727, SQL State: 56098] An error occurred during implicit system action type "2". Information returned for the error includes SQLCODE "-119", SQLSTATE "42803" and message tokens "Request_Detail".. SQLCODE=-727, SQLSTATE=56098, DRIVER=4.22.29
How could I do to get the count of the rows?
Which Request_Detail line's substr would you think it shows after the count?
If you count the lines, the result set will be a single line, and using any columns in it makes no sense.
If you want multiple lines, with a count for each found substr, you need to GROUP BY this substr.
This may work...
select
count(
SUBSTR("Request_Detail"
,LOCATE('/',"Request_Detail")+1
,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)
-LOCATE('/',"Request_Detail")))
)
from "Request_Analisys"
WHERE
"Sample_Date_and_Time">=1200323230000000 and "Sample_Date_and_Time"<1200332300000000
and "Request_Detail" <> '[Summary]'
and "Request_Detail" not like 'WS:%'
But if not this should..
with cte as (
select
SUBSTR("Request_Detail"
,LOCATE('/',"Request_Detail")+1
,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)
-LOCATE('/',"Request_Detail"))) as mydetail
from "Request_Analisys"
WHERE
"Sample_Date_and_Time">=1200323230000000 and "Sample_Date_and_Time"<1200332300000000
and "Request_Detail" <> '[Summary]'
and "Request_Detail" not like 'WS:%'
)
select count(*) from cte
I suggest you use REGEXP_EXTRACT to pick what you want out of your "Request_Detail" column. This is more flexable than using SUBSTR and LOCATE, and will avoid the statement was not executed because a numeric argument of a scalar function is out of range.. error
e.g
select
REGEXP_EXTRACT("Request_Detail",'.*/(.+/)',1,1,'',1)
, SUBSTR("Request_Detail",LOCATE('/',"Request_Detail")+1,LOCATE('/',"Request_Detail",LOCATE('/',"Request_Detail")+1)-LOCATE('/',"Request_Detail"))
FROM TABLE(VALUES('aaaa/bbbb/ccc')) AS T("Request_Detail")
returns
1 |2
------|-----
bbbb/ |bbbb/
so, you could then do this
SELECT
COUNT(*)
, REGEXP_EXTRACT("Request_Detail",'.*/(.+/)',1,1,'',1)
FROM
"Request_Analisys"
GROUP BY
REGEXP_EXTRACT("Request_Detail",'.*/(.+/)',1,1,'',1)
for example
The full error message is:

I'm pretty new to this stuff, so any help would be appreciated.
Not a problem of the function. Like the error messages says: The string '1e+06' cannot be cast to integer.
Obviously, the columns n_agents in your table results_20161109.initial_agent_count_by_tract_res_11 is not an integer column. Probably type text or varchar? (That info would help in your question.)
Either way, the assignment cast does not work for the target type integer. But it does for numeric:
Does not work:
SELECT '1e+06'::text::int; -- error as in question
Works:
SELECT '1e+06'::text::numeric::int;
If my assumptions hold, you can use this as stepping stone.
Replace b.n_agents in your query with b.n_agents::numeric::int.
It's your responsibility that numbers stay in integer range, or you get the next exception.
If that did not nail it, you need to look into function overloading:
Is there a way to disable function overloading in Postgres
And function type resolution:
PostgreSQL function call
The schema search path is relevant in many related cases, but you did schema-qualify all objects, so we can rule that out.
How does the search_path influence identifier resolution and the "current schema"
Your query generally looks good. I had a look and only found minor improvements:

ORDER BY pgid -- sort once in a subquery. cheaper.

When I try to run the following statement, I get this error:
"A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations."
DECLARE #OFR DECIMAL(18,2)
;
SELECT #OFR =
CASE SUM(ofr.Quantity)
WHEN 0 THEN 0
ELSE SUM(ofr.Gross) / SUM(ofr.Quantity)
END
FROM DistributionCosts ofr
;
SELECT #OFR
I just want to stick the result of that case statement into a variable and I'm getting stuck here.
Any ideas?
Thanks.
Are you sure this is where your error is? I just ran the statement below and it worked:
DECLARE #OFR DECIMAL(18,2)
;
with DistributionCosts as
(
select 1 as quantity, 5 as gross
union
select 5 , 20
)
SELECT #OFR =
CASE SUM(ofr.Quantity)
WHEN 0 THEN 0
ELSE SUM(ofr.Gross) / SUM(ofr.Quantity)
END
FROM DistributionCosts ofr
;
SELECT #OFR
If I select a column in addition to setting a variable I do get your error... If you are selecting another column you will need to either stop selecting that column or assign that column to a local variable as well.
I wish to write a Query for SAP B1 (t-sql) that will list all Income and Expenses Items by total and month by month.
I have successfully written a Query using PIVOT, but I do not want the column headings to be hardcoded like: Jan-11, Feb-11, Mar-11 ... Dec-11.
Rather I want the column headings to be parametrically generated, so that if I input:
--------------------------------------
Query - Selection Criteria
--------------------------------------
Posting Date greater or equal 01.09.10
Posting Date smaller or equal 31.08.11
[OK] [Cancel]
the Query will generate the following columns:
Sep-10, Oct-10, Nov-10, ..... Aug-11
I guess DYNAMIC PIVOT can do the trick.
So, I modified one SQL obtained from another forum to suit my purpose, but it does not work. The error message I get is Incorrect Syntax near 20100901.
Could anybody help me locate my error?
Note: In SAP B1, '[%1]' is an input variable

EXECUTE (#query)
I don't know SAP, but a couple of things spring to mind:
It looks like you want #listCol to contain a collection of numbers within square brackets, for example [07],[08],[09].... However, your code appears not to put a [ at the start of this string.
Try replacing the lines
T0.[Refdate] >= '[%1]' AND
T0.[Refdate] <= '[%2]'
with
T0.[Refdate] >= ''[%1]'' AND
T0.[Refdate] <= ''[%2]''
(I also added a space before the AND in the first of these two lines while I was editing your question.)
Greetings,
Here is my problem.
I need to get data from multiple rows and return them as a single result in a larger query.
I already posted a similar question here.
Return multiple values in one column within a main query but I suspect my lack of SQL knowledge made the question too vague because the answers did not work.
I am using Microsoft SQL 2005.
Here is what I have.
Multiple tables with CaseID as the PK, CaseID is unique.
One table (tblKIN) with CaseID and ItemNum(AutoInc) as the combined PK.
Because each person in the database will likely have more than one relative.
If I run the following, in a SQL query window, it works.
DECLARE #KINList varchar(1000)
SELECT #KINList = coalesce(#KINList + ', ','') + KINRel from tblKIN
WHERE CaseID = 'xxx' and Address = 'yyy'
ORDER BY KINRel
SELECT #KINList
This will return the relation of all people who live at the same address. the results look like this...
Father, Niece, Sister, Son
Now, the problem for me is how do I add that to my main query?
Shortened to relevant information, the main query looks like this.
SELECT DISTINCT
c.CaseID,
c.Name,
c.Address,
Relatives=CASE WHEN exists(select k.CaseID from tblKIN k where c.CaseID = k.CaseID)
THEN DECLARE #KINList varchar(1000)
SELECT #KINList = coalesce(#KINList + ', ','') + KINRel from tblKIN
WHERE CaseID = 'xxx' and Address = 'yyy'
ORDER BY KINRel
SELECT #KINList
ELSE ''
END
FROM tblCase c
ORDER BY c.CaseID
The errors I receive are.
Server: Msg 156, Level 15, State 1, Line 13
Incorrect syntax near the keyword 'DECLARE'.
Server: Msg 156, Level 15, State 1, Line 18
Incorrect syntax near the keyword 'ELSE'.
I tried nesting inside parenthesis from the DECLARE to the end of the SELECT #KINList.
I tried adding a BEGIN and END to the THEN section of the CASE statement.
Neither worked.
The source table data looks something like this. (periods added for readability)
tblCase
CaseID Name Address
10-001 Jim......100 Main St.
10-002 Tom....150 Elm St.
10-003 Abe.....200 1st St.
tblKIN
CaseID ItemNum Name Relation Address
10-001 00001 Steve...Son........100 Main St.
10-002 00002 James..Father....150 Elm St.
10-002 00003 Betty....Niece......150 Elm St.
10-002 00004 Greta...Sister.....150 Elm St.
10-002 00005 Davey..Son........150 Elm St.
10-003 00006 Edgar...Brother...200 1st St.
If I run the query for CaseID = 10-002, it needs to return the following.
CaseID Name Address.......Relatives
10-002 Tom...150 Elm St. ..Father, Niece, Sister, Son
I am sure this is probably a simple fix, but I just don't know how to do it.
Thank you for your time, and I apologize for the length of the question, but I wanted to be clear.
Thanks !!!
When I did something similar I had to create a scalar function to do the coalesce that returns the varchar result. Then just call it in the select.
CREATE FUNCTION GetRelatives
(
#CaseID varchar(10)
)
RETURNS varchar(1000)
AS
BEGIN
DECLARE #KINList varchar(1000)
SELECT #KINList = coalesce(#KINList + ', ','') + KINRel from tblKIN
WHERE CaseID = #CaseID
ORDER BY KINRel
RETURN #KINList
END
Then your select
SELECT DISTINCT
c.CaseID,
c.Name,
c.Address,
database.dbo.GetRelatives(c.CaseID) AS Relatives
FROM tblCase c
ORDER BY c.CaseID
You can create a FUNCTION which takes in the caseID as the arguement and returns true or false.
Since you are calling the nested query multiple times, its definitely a performance hit. A better solution is to execute the query and store the results in a temporary table.
Then pass this temporary table and the caseID to the FUNCTION and check for containment.
