How I can improve below code to use 'select' only once?
IF EXISTS (SELECT [NUMBER] FROM [TABLE] WHERE [ID_RECORD] = #id_record
BEGIN
DECLARE #tmp_variable
SELECT #tmp_variable = [NUMBER] FROM [TABLE] WHERE [ID_RECORD] = #id_record
SET #other_variable = #tmp_variable
END
ELSE
BEGIN
SET #other_variable = 0
END
Try This :
DECLARE #tmp_variable INT
SET #tmp_variable = ISNULL(( SELECT [NUMBER]
FROM [TABLE]
WHERE [ID_RECORD] = #id_record
), 0)
Try this solution:
DECLARE #tmp_variable int
SET #tmp_variable = null
SELECT #tmp_variable = [NUMBER] FROM [TABLE] WHERE [ID_RECORD] = #id_record
IF #tmp_variable is not null
BEGIN
SET #other_variable = #tmp_variable
END
ELSE
BEGIN
SET #other_variable = 0
END

In a stored procedure I am trying to add two numeric values as shown
DECLARE #tradeamt1 NUMERIC(23,2)
DECLARE #tradeamt3 NUMERIC(23,2)
DECLARE #value NUMERIC(23,2)
if (#retVal1 = 0)
BEGIN
SELECT #row_count = count(1),
#tradeamt1=Sum(trade_amt) ,
#units= Sum(curr_shrs_num)
FROM [csr_staging].[dbo].[fi_impact_source] WITH(NOLOCK)
Where acct_id = 'BANKFEES'
and SD_ID >= EFF_DT
print #tradeamt1
END
if(#retVal3 > 0)
BEGIN
select #row_count = count(1) - #retVal3 + #row_count,#tradeamt3=Sum(trade_amt),#units= #units +Sum(curr_shrs_num) - #currshares
FROM [CSR_Staging].[dbo].[fi_impact_source] WITH(NOLOCK)
where (clearing_code = 'MBS'or clearing_code = 'CNS') and (SD_ID >= EFF_DT)
print #tradeamt3
END
set #value = #tradeamt1 +#tradeamt3
this value gives null instead of adding tradeamount1 =1.00 and tradeamount3 = 191432650.13
Maybe this could work for your SP:
declare #tradeamt1 numeric(23, 2) = 0
, #tradeamt3 numeric(23, 2) = 0
, #value numeric(23, 2) = 0
select #row_count = 0, #units = 0
if #retVal1 = 0
select #row_count = count(1)
, #tradeamt1 = isnull(sum(trade_amt), 0)
, #units = isnull(sum(curr_shrs_num), 0)
from [CSR_Staging].[dbo].[fi_impact_source] with (nolock)
where acct_id = 'BANKFEES'
and SD_ID >= EFF_DT
if #retVal3 > 0
select #row_count = #row_count + count(1) - #retVal3
, #tradeamt3 = isnull(sum(trade_amt), 0)
, #units = #units + isnull(sum(curr_shrs_num), 0) - #currshares
from [CSR_Staging].[dbo].[fi_impact_source] with (nolock)
where clearing_code in ('MBS', 'CNS')
and SD_ID >= EFF_DT
set #value = #tradeamt1 + #tradeamt3
Using isNull( ensures that both #tradeamt1 and #tradeamt3 are not null
This is most probably because when tradeamt1 and tradeamt3 are not initialised and for some reason also not assigned values.
You could initialise them with:
DECLARE #tradeamt1 NUMERIC(23,2) = 0
DECLARE #tradeamt3 NUMERIC(23,2) = 0
DECLARE #value NUMERIC(23,2) = 0
Let me know if that helps.

The MIN function requires 1 argument(s).
set #TarnsportExemption = MIN(#MinConveyance,#MinTransport) - The MIN function is not what you think it is.
You probably want to do something like this:
set #TarnsportExemption = CASE WHEN #MinConveyance < #MinTransport THEN
#MinConveyance
ELSE
#MinTransport
END
Another option is this:
SELECT #TarnsportExemption = MIN(val)
FROM
(
SELECT #MinConveyance as val
UNION ALL
SELECT #MinTransport as val
)
And one more option is to use the values clause:
SELECT #TarnsportExemption = MIN(val)
FROM (VALUES ( #MinConveyance), (#MinTransport)) AS value(val)
Change your min statement like below MIN. Please refer MIN (Transact-SQL)
--fROM
set #TarnsportExemption = MIN(#MinConveyance,#MinTransport)
--To
SELECT #TarnsportExemption = MIN(A) FROM (
SELECT #MinConveyance A
UNION ALL
SELECT #MinTransport
)AS AA
In SQL, MIN function will return you minimum value of a column from selected list; so you can use MIN only in inline queries.
e.g. Select min(Salary) from Tbl_Employee
So, in your case either you can use case when then or union all to get minimum value from two variables as:-
SET #TarnsportExemption = CASE WHEN #MinConveyance < #MinTransport THEN #MinConveyance ELSE #MinTransport END
OR
SELECT #TarnsportExemption = MIN(TEMPS.[VALUE])
FROM (
SELECT #MinConveyance AS VALUE
UNION ALL
SELECT #MinTransport AS VALUE
) AS TEMPS
I am developing a stored procedure to update specific columns using parameters.
For example:
CREATE PROCEDURE save_proc
(
#userid varchar(5),
#column varchar(10),
#data varchar(50)
)
AS
BEGIN
UPDATE MyProfile
SET #column = #data
WHERE userid = #userid
The following is my code that I've tried but didn't work. Is it possible to do such an update by updating specific columns through parameters? Thanks
You can build up a query in your stored procedure and execute.
CREATE PROCEDURE save_proc
(
#userid varchar(5),
#column varchar(10),
#data varchar(50)
)
AS
BEGIN
exec sp_executesql N'UPDATE MyProfile SET ' + #column + '=''' + #data + ''' WHERE userid = ''' + #userid + ''''
END
The method may lead to security concern however.
Its doable but i would avoid doing it.... you code should be like below:
DECLARE #column varchar(10)
DECLARE #data varchar(50)
UPDATE DummyTable
SET
col1 = CASE WHEN #column = 'Col1' THEN #data ELSE col1 END ,
col2 = CASE WHEN #column = 'Col2' THEN #data ELSE col2 END
where userid = #userid
.
.
.
Hope that this is what you are looking for
Using a CASE statement causes all columns identified to once again be updated; this would invoke a reindexing for some indexes upon columns wherein that change, even if the same value, occurs. Waste of execution updates on server.
An IF statement is best option for single value, especially if value is NOT the same type as the column datatype.

A Try/Catch is advisable
I'm writing a stored procedure and it's working for if but not for else. For if I'm getting the correct ID value but for else it's just giving me null.
SELECT #ID = ID FROM PRODUCTS WHERE SN = #SN
SELECT #Chip_ID = Chip_ID FROM PRODUCTS WHERE SN = #SN
SELECT #Power = Power From Module_Cycle WHERE ChipID = #Chip_ID
SELECT #Test_ID=Test_ID FROM TestEE_Mod WHERE ID=#ID AND #TypeID = TypeID
IF(#Test_ID IS NOT NULL)
BEGIN
IF(#TypeID = '3')
BEGIN
SELECT #Temp_TestID=TestID FROM TempCycle WHERE ChipID = #Chip_ID AND #Power = 'false'
BEGIN
UPDATE TestEE_Mod SET Temp_TestID = #Temp_TestID WHERE ID = #ID AND TypeID = #TypeID
END
END
ELSE
BEGIN
SELECT #Temp_TestID=TestID FROM TempCycle WHERE ChipID = #Chip_ID AND #Power = 'true'
BEGIN
UPDATE TestEE_Mod SET Temp_TestID = #Temp_TestID WHERE ID = #ID AND TypeID = #TypeID
END
END
END
Most likely the issue lies in the #Power variable. In your two SELECT statements, the only difference is that one includes #Power = 'false' in the WHERE clause, while the other includes #Power = 'true'.
Since #Power is a variable, not an actual column in your TempCycle table, I'm guessing you actually meant to filter by Power = #Power in both of them.
I am getting the following error
An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Add a name or single space as the alias name.

Could you please help ?
You have 2 commas in a row here
#last_mod_user_id =last_mod_user_id ,
,#i=#i+1
Also probably not relevant to the error message but you have a line
Where #sup_id = supplier_id
but the declared variable is #supplier_id
