I am creating a temporary table in some dynamic SQL. But when I call it it throws an "Invalid object name '#Settlement_Data_Grouped'" error.
I am assuming it's because dynamic SQL uses it's own seperate instance? So that it is dropped and not available to the outside SQL? It works when I use ##Settlement_Data_Grouped or create a table. But this doesn't help when multiple people are calling the sproc.
I'm thinking I could check if the table exists but that would mean I would have to delete contents and different users may require different outputs which would mean it would not work.
So does anyone have a solution/suggestion I can use where multiple people can be calling the same sproc?
IMHO you do not need the Dynamic SQL. You can change your code like something below and that will give you same result as you are trying to accomplish. Please check for any syntax error if any. I would have provided you full query but in your question you have screenshot instead of the code. So here it goes.
If you want to use Temp Tables:
SELECT
......
INTO #Settlement_Data_Grouped
FROM #Settlement_Data
WHERE (Payment_Date < Settlement_Date AND #outputType = 1) ---This will be true when you have #outputType = 1
OR #outputType = 0 ---This will be true when you have #outputType = 0
GROUP BY Part_No
,NAME
,Order_No
,Invoice_No
-------------
SELECT
......
FROM #Settlement_Data_Grouped
If you want to use CTE:
WITH Settlement_Data_Grouped
AS (
SELECT
......
FROM #Settlement_Data
WHERE (Payment_Date < Settlement_Date AND #outputType = 1) ---This will be true when you have #outputType = 1
OR #outputType = 0 ---This will be ture when you have #outputType = 0
GROUP BY Part_No
,NAME
,Order_No
,Invoice_No
)
SELECT
......
FROM Settlement_Data_Grouped
The problem is that the temp table only exists within the scope of the dynamic SQL execution context. The way around it would be to create the temp table outside of the dynamic SQL and then insert into it:
CREATE TABLE #Settlement_Data_Grouped (PartNo varchar(50) ......)
INSERT INTO #Settlement_Data_Grouped
EXEC(#selectSQL)

I need to update a few thousand rows in my Postgres table using the result of a array_agg and spatial lookup.
The query needs to take the geometry of the parent table, and return an array of the matching row IDs in the other table. It may return no IDs or potentially 2-3 IDs.
I've tried to use an UPDATE FROM but I can't seem to pass into the subquery the parent table geom column for the SELECT. I can't see any way of doing a JOIN between the 2 tables.
Here is what I currently have:
UPDATE lrc_wales_data.records
SET lrc_array = subquery.lrc_array
FROM (
SELECT array_agg(wales_lrcs.gid) AS lrc_array
FROM layers.wales_lrcs
WHERE st_dwithin(records.geom_poly, wales_lrcs.geom, 0)
) AS subquery
WHERE records.lrc = 'nrw';
The error I get is:
ERROR: invalid reference to FROM-clause entry for table "records"
LINE 7: WHERE st_dwithin(records.geom_poly, wales_lrcs.geom, 0)
Is this even possible?
Many thanks,
Steve
Realised there was no need to use SET FROM. I could just use a sub query directly in the SET:
UPDATE lrc_wales_data.records
SET lrc_array = (
SELECT array_agg(wales_lrcs.gid) AS lrc
FROM layers.wales_lrcs
WHERE st_dwithin(records.geom_poly, wales_lrcs.geom, 0)
)
WHERE records.lrc = 'nrw';
Here is a simple PostgreSQL update returning some data:
UPDATE table set num = num + 1
WHERE condition = true
RETURNING table.id, table.num
Is there a way to further use the returned results, as if they came from a select statement? Something like this:
INSERT into stats
(id, completed)
SELECT c.id, TRUE
FROM
(
UPDATE table set num = num + 1
WHERE condition = true
RETURNING table.id, table.num
) c
where c.num > 5
Or do I have to save the returned results into my application, then create a new query out of the returned results?
As of version 9.1, you can use an UPDATE ... RETURNING in a "Common Table Expression" ("CTE"), which for most purposes can be thought of as a named sub-query.
So for your purposes, you could use something like this:
WITH update_result AS
(
UPDATE table set num = num + 1
WHERE condition = true
RETURNING table.id, table.num
)
INSERT into stats
(id, completed)
SELECT c.id, TRUE
FROM update_result as c
WHERE c.num > 5
If you're using a version of Postgres below 9.1, then I think you will have to grab the result into a variable in some procedural code - either your application, or a database function (probably written in PL/pgSQL).
That syntax won't work (unfortunately! that would be convenient).
Either you update and then create another query, or you do everything in a stored procedure where you can safely store and handle query resuts, so that you just have one single database call from your application.
I am trying to create a stored procedure that will split 3 text boxes on a webpage that have user input that all have comma delimited strings in it. We have a field called 'combined_name' in our table that we have to search for first and last name and any known errors or nicknames etc. such as #p1: 'grei,grie' #p2: 'joh,jon,j..' p3: is empty.
The reason for the third box is after I get the basics set up we will have does not contain, starts with, ends with and IS to narrow our results further.
So I am looking to get all records that CONTAINS any combination of those. I originally wrote this in LINQ but it didn't work as you cannot query a list and a dataset. The dataset is too large (1.3 million records) to be put into a list so I have to use a stored procedure which is likely better anyway.
Will I have to use 2 SP, one to split each field and one for the select query or can this be done with one? What function do I use for contains in tsql? I tried using IN win a query but cannot figure out how it works with multiple parameters.
Please note that this will be an internal site that has limited access so worrying about sql injection is not a priority.
I did attempt dynamic SQL but am not getting the correct results back:
CREATE PROCEDURE uspJudgments #fullName nvarchar(100) AS
EXEC('SELECT *
FROM new_judgment_system.dbo.defendants_ALL
WHERE combined_name IN (' + #fullName + ')')
GO
EXEC uspJudgments #fullName = '''grein'', ''grien'''
Even if this did retrieve the correct results how would this be done with 3 parameters?
You may try use this to split string and obtain a tables of strings. Then to have all the combinations you may use full join of these two tables. And then do your select.
Here is the Table valued function I set up:
ALTER FUNCTION [dbo].[Split] (#sep char(1), #s varchar(8000))
RETURNS table
AS
RETURN (
WITH splitter_cte AS (
SELECT CHARINDEX(#sep, #s) as pos, 0 as lastPos
UNION ALL
SELECT CHARINDEX(#sep, #s, pos + 1), pos
FROM splitter_cte
WHERE pos > 0
)
SELECT SUBSTRING(#s, lastPos + 1,
case when pos = 0 then 80000
else pos - lastPos -1 end) as OutputValues
FROM splitter_cte
)
)
I must to write a UDF returning a Table. I’ve done it with Static SQL.
I’ve created Procedures preparing a Dynamic and Complex SQL sentence and returning a cursor.
But now I must to create a UDF with Dynamic SQL and return a table to be used with an IN clause inside other select.
It is possible on DB2 v5R4? Do you have an example?
Thanks in advance...
I don't have V5R4, but I have i 6.1 and V5R3. I have a 6.1 example, and I poked around in V5R3 to find how to make the same example work there. I can't guarantee V5R4, but this ought to be extremely close. Generating the working V5R3 code into 'Run SQL Scripts' gives this:
DROP SPECIFIC FUNCTION SQLEXAMPLE.DYNTABLE ;
SET PATH "QSYS","QSYS2","SYSPROC","SYSIBMADM","SQLEXAMPLE" ;
CREATE FUNCTION SQLEXAMPLE.DYNTABLE (
SELECTBY VARCHAR( 64 ) )
RETURNS TABLE (
CUSTNBR DECIMAL( 6, 0 ) ,
CUSTFULLNAME VARCHAR( 12 ) ,
CUSTBALDUE DECIMAL( 6, 0 ) )
LANGUAGE SQL

BEGIN
DECLARE DYNSTMT VARCHAR ( 512 ) ;
DECLARE GLOBAL TEMPORARY TABLE SESSION.TCUSTCDT
( CUSTNBR DECIMAL ( 6 , 0 ) NOT NULL ,
CUSTNAME VARCHAR ( 12 ) ,
CUSTBALDUE DECIMAL ( 6 , 2 ) )
WITH REPLACE ;
SET DYNSTMT = 'INSERT INTO Session.TCustCDt SELECT t2.CUSNUM , (t2.INIT CONCAT '' '' CONCAT t2.LSTNAM) as FullName , t2.BALDUE FROM QIWS.QCUSTCDT t2 ' CONCAT CASE WHEN SELECTBY = '' THEN '' ELSE SELECTBY END ;
EXECUTE IMMEDIATE DYNSTMT ;
RETURN SELECT * FROM SESSION . TCUSTCDT ;
END ;
COMMENT ON SPECIFIC FUNCTION SQLEXAMPLE.DYNTABLE
IS 'UDTF returning dynamic table' ;
And in 'Run SQL Scripts', the function can be called like this:
SELECT t1.* FROM TABLE(sqlexample.dyntable('WHERE STATE = ''TX''')) t1
The example is intended to work over IBM's sample QCUSCDT table in library QIWS. Most systems will have that table available. The table function returns values from two QCUSCDT columns, CUSNUM and BALDUE, directly through two of the table function's columns, CUSTNBR and CUSTBALDUE. The third table function column, CUSTFULLNAME, gets its value by a concatenation of INIT and LSTNAM from QCUSTCDT.
However, the part that apparently relates to the question is the SELECTBY parameter of the function. The usage example shows that a WHERE clause is passed in and used to help built a dynamic 'INSERT INTO... SELECT...statement. The example shows that rows containingSTATE='TX'` will be returned. A more complex clause could be passed in or the needed condition(s) could be retrieved from somewhere else, e.g., from another table.
The dynamic statement inserts rows into a GLOBAL TEMPORARY TABLE named SESSION.TCUSTCDT. The temporary table is defined in the function. The temporary column definitions are guaranteed (by the developer) to match the 'RETURNS TABLE` columns of the table function because no dynamic changes can be made to any of those elements. This allows SQL to handle reliably columns returned from the function, and that lets it compile the function.
The RETURN statement simply returns whatever rows are in the temporary table after the dynamic statement completes.
The various field definitions take into account the somewhat unusual definitions in the QCUSTCDT file. Those don't make great sense, but they're useful enough.
I have a spreadsheet with multiple columns, one of which is an owner_id column. The problem is that this column contains a comma delimited list of owner id's and not just a single one.
I've imported this spreadsheet into my sql database (2008) and have completed other importing tasks and now have a parcel_id column as a result of this process.
I need to create an entry in my parcelOwners table for each parcelID/ownerID pair, but I'm not sure how to go about this with the owner id's being in the comma delimited list.
My tables look like this:
ImportData
=================
owner_id varchar,
parcelID int
sample row (owner_id = '13782, 21431', parcelID = 319)
ParcelOwners
=================
ownerID int,
parcelID int
row from ImportData table should look like:
ownerID = 13782, parcelID = 319
ownerID = 21431, parcelID = 319
Is this a common situation for anybody and if so, how do you go about getting around this?
The below function will split you comma sep column into a table. You will then need to iterate through the temp table and insert 1 row into your parcelOwners table using the data from your single column. To get this to work you will need an outer loop to iterate through the parcelOwners table and an inner loop to iterate through the #temptable for each row. Also, don't forget, if you come to a row in your outer loop with no comma's in the owner_id column you won't want to do anything.
CREATE FUNCTION dbo.Split(#String varchar(8000), #Delimiter char(1))
returns #temptable TABLE (items varchar(8000))
as
begin
declare #idx int
declare #slice varchar(8000)
select #idx = 1
if len(#String)<1 or #String is null return
while #idx!= 0
begin
set #idx = charindex(#Delimiter,#String)
if #idx!=0
set #slice = left(#String,#idx - 1)
else
set #slice = #String
if(len(#slice)>0)
insert into #temptable(Items) values(#slice)
set #String = right(#String,len(#String) - #idx)
if len(#String) = 0 break
end
return
end
You can do this easily leveraging SQL Server's XML functions:
WITH xmlData (xml_owner_id,parecelID) AS (
/* make into xml */
SELECT cast('<x>'+replace(owner_id,',','</x><x>')+'</x>' as XML) AS xml_owner_id, parecelID
FROM ImportData
)
SELECT x.value('.','int') AS owner_id, parecelID /* split up */
FROM xmlData
CROSS APPLY xmlData.xml_owner_id.nodes('//x') AS func(x)
(In response to #senloe's question about how to use the function supplied by #RandomBen)
This answer to a previous question shows how to use OUTER APPLY to apply a function to every row in a table. In your case, and assuming you have already run #RandomBen's code to create the dbo.Split function, the syntax would look something like this:
INSERT INTO ParcelOwners (ownerId, parcelID)
SELECT CONVERT(int, Results.items), ImportData.parcelID
FROM ImportData
OUTER APPLY dbo.Split(ImportData.owner_id, ',') AS Results
(I don't have access to SQL Server right now, so I haven't tried it yet. You can run it without the first line, i.e. just from SELECT onwards, to see what output it is going to generate before you actually do the INSERT).
