create stored procedure to execute on a remote machine

Hi, I am using the below query and works fine.

DECLARE @ProductName nvarchar(250) = 'Camera', @ProductDescription nvarchar(250) = 'DSLR camera'

DECLARE @query NVARCHAR(MAX)

    SET @query = 'EXEC (''INSERT INTO [dbo].[Products] ([ProductName], [ProductDescription]) VALUES (?,?)'',''' + @ProductName + ''',''' + @ProductDescription + ''') AT [linkedserver]'   PRINT @query -- EXEC ('INSERT INTO [dbo].[Products] ([ProductName], [ProductDescription]) VALUES (?,?)','Camera','DSLR camera') AT [linkedserver]

But when I try to write the same query as a stored procedure and do a jdbc call the stored procedure does nothing.

CREATE PROCEDURE [dbo].[testsp] @ProductName nvarchar(250), @ProductDescription nvarchar(250)
AS

DECLARE @query NVARCHAR(MAX)

    SET @query = 'EXEC (''INSERT INTO [dbo].[Products] ([ProductName], [ProductDescription]) VALUES (?,?)'',''' + @ProductName + ''',''' + @ProductDescription + ''') AT [linkedserver]'   EXEC sp_executesql @stmt = @query

In the javascript application call the stored procedure as below.

call [dbo].[testsp](?,?)

The stored procedure does not throw any errors as such nor does it insert data. Could please point me if I am missing something.

Thank you in advance.

declare  @t table

select 3,3
union
select 4,15
union
select 5,23
union
select 6,10

select * from @t

Above is the my table script and if I give value 26 then it should be subtract from the 'value' column.

Below is the expected out put 



First the input value should be subtract the first 'id'

input value --> 26 

id#1 --> 0 (26-10)

id#2 --> 0 (16-12)

id#3 --> 0(4-3)

id#4 --> 14 (1-15)

Can we do it with out While loop?

Deadlock due to Shared lock acquiring on parent table

We are getting deadlock when we update a child table by using primary key in where condition . the deadlock graph show that a shared lock was acquiring  on parent table in one execution and and in other execution it is acquiring  exclusive lock.

why the update is locking the parent table , is there any way to avoid the parent table locking .

sample code 

update table1

   id  =@va

where table1_PK=@value

here in id column we have defined a fk which reference another table

I want to work out to create next hierarchy sequence id when reparenting hierarchy tree

i.e.

HID tree /3/, /3/1/, /3/2/, /3/2/1/, /3/2/2/, /3/2/3/

Reparenting /3/2/.... tree to /5/ will remain /5/2/ and it's subsequent series.

Is there any way when we can start /5/1/ if there is no child and if any child get next HID i.e /5/2/ and so on.

SELECT * Result into a string ?

Hi !

This is for an attempt at a  trigger script that will be on many *different* tables, thus I do not know number of columns, their names or their data types. That is why I am looking for SQL Server to get the Select result as an output string.

Is it at all possible to get a "SELECT * FROM inserted" result into a string WITHOUT looping the inserted table or some object ?
I was hoping for some internal function that could do it or if there is some clever other way.

Thanks !

Fetching all rows in a triggers 'inserted' table possible?

Hi !

I am using SQL Broker Service with contracts etc and in the update trigger of a table is the code below, however it only fetches 1 row from the inserted table and sends it as xml by message.

My question is how to get all rows in 'inserted' and sending them as an xml message *without* having an outer WHILE LOOP ?

SET @MessageBody = (SELECT Id, uuid, Misc1, Misc2, Date, Dept FROM inserted
FOR XML AUTO)              

If (@MessageBody IS NOT NULL)
BEGIN

DECLARE @Handle UNIQUEIDENTIFIER;  
BEGIN DIALOG CONVERSATION @Handle  
FROM SERVICE [TestServiceInitiator]  
TO SERVICE 'TestServiceTarget'  
ON CONTRACT [TestContract]  
WITH ENCRYPTION = OFF;  
SEND ON CONVERSATION @Handle  
MESSAGE TYPE [TestMessage](@MessageBody);
END

Best Regards, Scand

Problem in apportion

Hi guys, 

I have a big problem wit the apportion. The sum of the percentage is always 99.1 / 99.2 and this is not acceptable. The percentage comes from something like this

with zz (

select sum (TotF) TF, pp from TableOne group by pp)

select pp, TF*OldValue as percentage from azz inner join....

where totF is numeric (18,3) and OldValue is numeric (38,10). i changed today the OldValue from numeric(38,6) to numeric (38,10). 

The query above is (as example) my view and if I see the property of the view the column percentage is numeric (38,6). 

I would like to have a numeric 38,10 or 38,12 so I can have a more accurate percentage and a more meaningful total (not 99.1 or 99.2 but at least 99.8/99.9)

Any advice?

Hi All, 

I have been struggling to understand this query , however I have to rewrite it to improve the performance as tabe has records in millions and can not afford multiple joins to the same table.

SELECT DISTINCT 1.A_ID 
FROM ABC 1
INNER JOIN ABC 2 ON 1.ID = 2.ID
INNER JOIN ABC 3 ON 3.ID = 2.MATCH_P_ID
LEFT OUTER JOIN OTHER_TABLE O ON  O.SOME_COL = 2.SOME_COL
WHERE 1.TYPE =1 AND O.VALUES IN ( 100,101,102)


I do not have an execution plan and no idea about indexes on the table, I will reach out to DBAs to see that  ,however I want to know if anyway rewriting can happen here.

Thank you !

Challenge with Linking

April 14, 2020, 10:33 am

I'm trying to link 3 tables and produce one summary line with different level groupings.  The best way to make this clear is to provide an example.  Table names are underlined.  Example data is in brackets.

Item Master
Item Number
Qty on Order
[Widget, 2]

PO
PO Number
Item Number
Qty Ordered
[PO1, Widget, 5]
[PO2, Widget, 5]

Receipts
PO Number
Item Number
Qty Received
[PO1, Widget, 2]
[PO1, Widget, 1]
[PO2, Widget, 5]

The results should be one row per item number. Based on the above info, that would be as follows:

Results
Item Number [Widget]
Qty on Order [2]
Qty Ordered [10]
Qty Received [8]

We are troubleshooting instances where the Qty on Order does not match the Qty Ordered - Qty Received.  The above example ties out.

My challenge is the three layers.  There are multiple POs for each item.  And then multiple receipts for each PO.

We are seeing issue with one of our production server Log file getting filled up. Some transaction is filling up the space. How do I identify the long running transaction when it runs ? Its mostly from one of the jobs that run late night.

Also how can I automate a script to Shrink Logfiles ? I did using SSMS but would like to see if there is any way through T SQL and automate to run every few hours?

Getting dynamically values separated by commas

April 14, 2020, 3:49 pm
$
0

Hi there,

In a query, imagine you need to get the values separated by commas in a dynamic column where you have sometimes four, five or six values.

Let me show you:

--declare @core_value varchar(200) = 'microwave,oven,dish_washer,refrigerated,pressure_cooker,steamer';
declare @core_value varchar(200) = 'microwave,oven,dish_washer,refrigerated';


--getting the number of commas plus 1 in order to know in advance how many values need to split out
SELECT (LEN(@core_value) - LEN(REPLACE(@core_value, ',', ''))) + 1  as Number_of_Times

SELECT dbo.GetColumnValue(@core_value, ',', 1) as Product_Support_Devices1
,dbo.GetColumnValue(@core_value, ',', 2) as Product_Support_Devices2
,dbo.GetColumnValue(@core_value, ',', 3) as Product_Support_Devices3
,dbo.GetColumnValue(@core_value, ',', 4) as Product_Support_Devices4
,dbo.GetColumnValue(@core_value, ',', 5) as Product_Support_Devices5
,dbo.GetColumnValue(@core_value, ',', 6) as Product_Support_Devices6

If you run the above query you will get "Product_Support_Devices5" and "Product_Support_Devices6" with fake values, in fact they don't exist, however the UDF (below) extract a value not a NULL

UDF am I using:

CREATE FUNCTION dbo.GetColumnValue(
    @String VARCHAR(MAX),
    @Delimiter CHAR(1),
    @Column INT = 1
)
RETURNS VARCHAR(MAX)
AS    
BEGIN
DECLARE @idx INT
DECLARE @slice VARChar(MAX)     
SELECT @idx = 1     
    IF LEN(@String)<1 OR @String IS NULL
        RETURN NULL
DECLARE @ColCnt INT
    SET @ColCnt = 1
WHILE (@idx != 0)
BEGIN    
    SET @idx = CHARINDEX(@Delimiter,@String)     
    IF @idx!=0 
    BEGIN
        IF (@ColCnt = @Column) 
            RETURN LEFT(@String,@idx - 1)        
        SET @ColCnt = @ColCnt + 1
    END
    SET @String = RIGHT(@String,LEN(@String) - @idx)     
    IF LEN(@String) = 0 BREAK
END
RETURN @String  
END

So the idea is getting real values not repeated ones

Thanks for your inputs/hints

Hi All,

Thank you for helping others who are in need.

I have a requirement where i need to calculate the calc_wrkhrs field (which is in mustard color) from the attached excel

I have 3 tables Payrolltable, Census table and quickbasetable

Based on the quick base table the values in workedhrs column the hours should sum up from Payroll table.

1- Regular is always comes in Payroll Table (this we can sum up with no issue) in the excel i did not sum up this

for ex

for employeid 2180, pay group  YOR, and Unicode  VA4-NOCBA : the column 'workedhours' has values  22- Training, 20 -Holiday (please ignore 1- Regular (this is a compulsary column in Payrolltable only other columns will vary) 

 Pick these values 22- Training, 20 -Holiday Worked match to hrs_22 and hrs_20 columns in Payroll table and provide the sum

the color blue and green in the excel determines the how the values are associated with unicode 

Please find the required code for the table creation and attached the excel for reference to  give an idea.

Thank you in Advance

create table quickbase (
paygroup varchar(3),
unioncd varchar(20),
workedhrs varchar(8000)
)
insert into quickbase values ('Y0R','VA4-NOCBA','1 - Regular;22 - Training;20 - Holiday Worked');
insert into quickbase values ('Y0R','NJ2-WJHTCS','1 - Regular;22 - Training;20 - Holiday Worked;HLW - Holiday Worked;GM - Guard Mount');

create table census (
paygroup varchar(3),
empid bigint,
unioncd varchar(20) ) 
insert into census values ('Y0R',21840,'VA4-NOCBA')
insert into census values ('Y0R',19948,'NJ2-WJHTCS')

create table payroll (
paygroup varchar(3),
empid bigint,
rg_hrs decimal(20,0),
hrs_20 decimal(20,0),
hrs_22 decimal(20,0),
hrs_hlw decimal(20,0),
hrs_gm decimal(20,0),
upd_date datetime default getdate()
)
truncate table payroll
insert into payroll(paygroup,empid,rg_hrs,hrs_20,hrs_22,hrs_hlw) values ('Y0R',21840,5,0,5,10);  --- 1 emp can have multiple recs in payroll table 
insert into payroll(paygroup,empid,rg_hrs,hrs_20,hrs_22) values ('Y0R',21840,70,8.0,0); --- 1 emp can have multiple recs in payroll table 
insert into payroll(paygroup,empid,rg_hrs,hrs_20,hrs_22,hrs_hlw,hrs_gm) values ('Y0R',19948,75,12.0,11.0,5,4);

Hi All,

Today I was checking a database log file full issue. {The transaction log for database 'XXX' is full due to 'LOG_BACKUP'}

Found log backup was never taken on the database. So issued log backup manually & after that there was 99% free space available on the log file.

Immediately after taking log backup, I was trying to shrink the file. But by mistake, instead of choosing the reorganize option & I have clicked on option 'empty file by migrating data to other files in the same file group'.

There is only one log file present on the DB. I am worried, if it would have caused any data loss. Please suggest.

Thank You!
