I want to save data in a variable and use it later in a procedure.
UPDATE acc_Account
SET acc_Account.CompanyID = ( SELECT TOP 1
utl_Company.CompanyID
FROM utl_Company
ORDER BY CompanyID DESC
)
WHERE acc_Account.AccountNumber = #AccountNumber
how can I save the CompanyID in a variable to use it in an insert statement later on?
Have this in the beginning of your code:
declare #var varchar(20) -- change the data type according to your needs
set #var = (SELECT TOP 1 utl_Company.CompanyID FROM utl_Company ORDER BY CompanyID DESC)
Create a select local variable before the update statement, then set it, then use it.
DECLARE #companyID INT;
SELECT #companyID = "YOUR QUERY";
I think the efficient way would be using OUTPUT clause
DECLARE #TAB TABLE (CompanyID BIGINT )
UPDATE acc_Account
SET acc_Account.CompanyID = (
SELECT max(CompanyID) FROM utl_Company
)
output inserted.CompanyID into #TAB
WHERE acc_Account.AccountNumber = #AccountNumber
SELECT * FROM #TAB

I'm trying to set a couple of variables, one is a name of the table (#table), the other one is a string.
I've got the error message:
Must declare the table variable "#table".
as far as I could understand it's because I must use #table as a table variable, but I just need it as a string
declare #a varchar(50);
declare #table varchar(100);
select #table =
case
WHEN Version = 'Advanced' THEN ("tableadv")
WHEN Version = 'Professional' THEN ("tablepro")
WHEN Version = 'Light' THEN ("tablelight")
WHEN Version = 'Short' THEN ("tableshort")
END
FROM partno where inpn=3
set #a = (select top (1) LicenseNumber from #table where used is null)
insert into seriali (LicenseNumber, idpn, serdgtrace)
select #a, 2, 'DAT-enrico'
update #table set used = 1 where LicenseNumber=#a
any help will be appreciated.
Many thanks,
enrico
You need table variable not only variable to store more values with more columns not just single value :
declare #table table (
#col int,
. . .
)
insert into #table (col)
select case WHEN Version = 'Advanced' THEN 'tableadv'
WHEN Version = 'Professional' THEN 'tablepro'
WHEN Version = 'Light' THEN 'tablelight'
WHEN Version = 'Short' THEN 'tableshort'
end
from partno
where inpn = 3
hello Yogesh and thanks for the answer,
anyway I need this case structure to pick the right table name based on a field in another table.
Then I have to pass this value to update the right table;
set #a = (select top (1) LicenseNumber from #table where used is null)
update #table set used = 1 where LicenseNumber=#a
I don't need to build a table variable with one of the case values in a record, because I won't be able to pass the right table name either
Many thanks,
Enrico
I would like to create a view at the end of the following request.
I know that 'create view' must be the first statement in a query batch. My problem is that for this query i must use a variable (#listOfIDRUB).
This variable is only fill correctly at the end of my little script.
I also have tried to create the view before my first declaration but it created a problem with "DECLARE".
So is it possible to create a view easily from the result of my script or i have to do something else ?
DECLARE #CounterResId int;
DECLARE #lePath varchar(255);
DECLARE #listOfIDRUB TABLE (EXTERNALREFERENCE uniqueidentifier, ID varchar(255), DOCID varchar(255) );
DECLARE #Max int;
SET #lePath = '';
SET #CounterResId = 1;
SET #Max = (SELECT COUNT(*) FROM SYNTHETIC..EXTRANET_PURGE WHERE TYPE_SUPPR = 'ResId')
WHILE (#CounterResId <= #Max )
BEGIN;
set #lePath =
(select tmp.lePath from
(
select row_number() over(order by path)as NumLigne, CONCAT(path, '%' ) as lePath from RUBRIQUE
WHERE MODELE = 'CAEEE64D-2B00-44EF-AA11-6B72ABD9FE38'
and CODE in (SELECT ID FROM SYNTHETIC..EXTRANET_PURGE where TYPE_SUPPR='ResId')
) tmp
WHERE tmp.NumLigne = #CounterResId)
INSERT INTO #listOfIDRUB(EXTERNALREFERENCE, ID, DOCID)
SELECT SEC.EXTERNALREFERENCE , SEC.ID, SEC.DOCUMENTID
FROM WEBACCESS_FRONT..SECTIONS sec
inner join rubrique rub ON rub.ID_RUBRIQUE = sec.EXTERNALREFERENCE
inner join template_tree_item tti ON tti.id_template_tree_item = rub.modele
inner join template t ON t.id_template = tti.template
WHERE t.CODE IN (SELECT TEMPLATE_CODE from SYNTHETIC..EasyFlowEngineListTemplateCode)
and rub.path like #lePath
print #CounterResId;
print #lePath;
set #CounterResId = #CounterResId + 1;
END;
select * from #listOfIDRUB;
Instead of select * from #listOfIDRUB
i wanted create view test as select * from listOfIDRUB
I have also tried create view test as (all my request)
Whenever you ask something about SQL please state your RDBMS (product and version). The answers are highly depending on this...
From your code I assume this is SQL Server.
So to your question: No, a VIEW must be "inlineable" (single-statement or "ad-hoc") statement.
You might think about a multi-statement UDF, but this is in almost all cases a bad thing (bad performance). Only go this way, if your result table will consist of rather few rows!
Without knowing your tables this is rather blind walking, but you might try this (add parameters, if you can transfer external operations (e.g. filtering) into the function):
CREATE FUNCTION dbo.MyFunction()
RETURNS #listOfIDRUB TABLE (EXTERNALREFERENCE uniqueidentifier, ID varchar(255), DOCID varchar(255) )
AS
BEGIN
DECLARE #CounterResId int;
DECLARE #lePath varchar(255);
DECLARE #Max int;
SET #lePath = '';
SET #CounterResId = 1;
SET #Max = (SELECT COUNT(*) FROM SYNTHETIC..EXTRANET_PURGE WHERE TYPE_SUPPR = 'ResId')
WHILE (#CounterResId <= #Max )
BEGIN;
set #lePath =
(select tmp.lePath from
(
select row_number() over(order by path)as NumLigne, CONCAT(path, '%' ) as lePath from RUBRIQUE
WHERE MODELE = 'CAEEE64D-2B00-44EF-AA11-6B72ABD9FE38'
and CODE in (SELECT ID FROM SYNTHETIC..EXTRANET_PURGE where TYPE_SUPPR='ResId')
) tmp
WHERE tmp.NumLigne = #CounterResId)
INSERT INTO #listOfIDRUB(EXTERNALREFERENCE, ID, DOCID)
SELECT SEC.EXTERNALREFERENCE , SEC.ID, SEC.DOCUMENTID
FROM WEBACCESS_FRONT..SECTIONS sec
inner join rubrique rub ON rub.ID_RUBRIQUE = sec.EXTERNALREFERENCE
inner join template_tree_item tti ON tti.id_template_tree_item = rub.modele
inner join template t ON t.id_template = tti.template
WHERE t.CODE IN (SELECT TEMPLATE_CODE from SYNTHETIC..EasyFlowEngineListTemplateCode)
and rub.path like #lePath
--print #CounterResId;
--print #lePath;
set #CounterResId = #CounterResId + 1;
END;
RETURN;
END
You can call it like this (very similar to a VIEW)
SELECT * FROM dbo.MyFunction();
And you might even use it in joins...
And last but not least I'm quite sure, that one could solve this without declares and a loop too...
My problem is using a table variable in a exec.
declare #sort_col nvarchar(1000) = 'itm_id'
declare #sort_dir nvarchar(4) = 'desc'
declare #filters nvarchar(1000) = ' and itm_name like ''%aa%'''
declare #temp table
(
itm_id int
)
insert into #temp
EXEC('select itm_id from Tblitm where itm_name not like ''%aa%''')
EXEC('select * from (select (ROW_NUMBER() OVER (ORDER BY '+#sort_col+' '+#sort_dir+')) row_num, * FROM (select itm_id, itm_name,
dbo.fnItmsHistory(itm_id) itm_history
from dbo.Tblitm as itm
left outer join '+#temp+' as temp on itm.itm_id = temp.itm_id
where itm_id=itm_id and temp.itm_id = null '+#filters+') as x) as tmp')
It says Must declare the scalar variable "#temp" when the temp table is declared i tried using original temp table and it worked, but i had problems when trying to update my entity model.So is there any solution for this problem?
Note:
I must use exec because in filters i store string for the where clause.
Try moving the table variable inside the dynamic statement.
EXEC('
declare #temp table
(
itm_id int
)
insert into #temp
select itm_id from Tblitm where itm_name not like ''%aa%''
select * from (select (ROW_NUMBER() OVER (ORDER BY '+#sort_col+' '+#sort_dir+')) row_num, * FROM (select itm_id, itm_name,
dbo.fnItmsHistory(itm_id) itm_history
from dbo.Tblitm as itm
left outer join #temp as temp on itm.itm_id = temp.itm_id
where itm_id=itm_id and temp.itm_id = null '+#filters+') as x) as tmp')
For solution i had to use a temp table and then on the start of my stored procedure i used the if condition from the EF can't infer return schema from Stored Procedure selecting from a #temp table anwser.
It's the best solution for this scenario i think.
EXEC [dbo].[SP]
#Param = ( SELECT COUNT(id) FROM TABLE )
Gives errors, so what's the next best thing or what am I doing wrong?
Without using Declare Set etc. etc.
Set it before you run the stored proc?
SET #Para1 = (SELECT COUNT(id) FROM TABLE)
EXEC [dbo].[SP] #Param = #Para1
Is there a more efficient way to write this code? Or with less code?
SELECT *
INTO #Temp
FROM testtemplate
Declare #id INT
Declare #name VARCHAR(127)
WHILE (SELECT Count(*) FROM #Temp) > 0
BEGIN
SELECT TOP 1 #id = testtemplateid FROM #Temp
SELECT TOP 1 #name = name FROM #Temp
UPDATE testtemplate
SET testtemplate.vendortestcode = (SELECT test_code FROM test_code_lookup WHERE test_name = #name)
WHERE testtemplateid = #id
--finish processing
DELETE #Temp Where testtemplateid = #id
END
DROP TABLE #Temp
You can do this in a single UPDATE with no need to loop.
UPDATE tt
SET vendortestcode = tcl.test_code
FROM testtemplate tt
INNER JOIN test_code_lookup tcl
ON tt.name = tcl.test_name
You could try a single update like this:
UPDATE A
SET A.vendortestcode = B.test_code
FROM testtemplate A
INNER JOIN test_code_lookup B
ON A.name = B.test_name
Also, the way you are doing it now is wrong, since you are taking a TOP 1 Id and a TOP 1 name in two separate querys, without an ORDER BY, so its not sure that you are taking the right name for your ID.
You could write a function to update vendortestcode. Then your code reduces to one SQL statement:
update testtemplate set vendortestcode = dbo.get_test_code_from_name(name)
