I have table like this
CREATE TABLE [dbo].[Product](
[Id] [int] IDENTITY(1,1) NOT NULL,
[Name] [nvarchar](100) NOT NULL,
[Description] [nvarchar](max) NOT NULL,
[Price] [decimal](16, 3) NOT NULL,
[SmallPhoto] [varbinary](max) NULL);
I want load image into [SmallPhoto] field
Main script looks like this
declare #filePath varchar(max)
declare #productId int
set #filePath = 'D:\myfile.png'
set #productId = 1
update Product
set SmallPhoto = -- some actions
where Id = #productId
Expected result
Command(s) completed successfully. :)
UPD:
1) My database located in other machine
2) I do not have opportunity to copy file to remote machine

We receive 10 images in varchar format through a mobile device app which are stored in one record of a table. The fields where the images are imported are named ImportPictureData, ImportPictureData2,...
[ID] [int] IDENTITY(1,1) NOT NULL,
[Projectnumber] [varchar](20) NULL,
[DeviceID] [nchar](20) NULL,
[Sendtime] [datetime] NULL,
[DeviceName] [nchar](30) NULL,
[ImportPictureData] [varchar](max) NULL,
[PictureData] [varbinary](max) NULL,
[ImportPictureData2] [varchar](max) NULL,
[PictureData2] [varbinary](max) NULL,
[ImportPictureData3] [varchar](max) NULL,
[PictureData3] [varbinary](max) NULL,
[ImportPictureData4] [varchar](max) NULL,
[PictureData4] [varbinary](max) NULL,
[ImportPictureData5] [varchar](max) NULL,
[PictureData5] [varbinary](max) NULL,
[ImportPictureData6] [varchar](max) NULL,
[PictureData6] [varbinary](max) NULL,
[ImportPictureData7] [varchar](max) NULL,
[PictureData7] [varbinary](max) NULL,
[ImportPictureData8] [varchar](max) NULL,
[PictureData8] [varbinary](max) NULL,
[ImportPictureData9] [varchar](max) NULL,
[PictureData9] [varbinary](max) NULL,
more of the importfields could be added.
To make the export flexible, I read the fieldnames in a table variable and try to create a dynamic SQL for the loop through the fields.
The SQL-string looks good where I create the string and print it(!) and then I try to assign the string to the variable which should recieve the image data:
set #sqlDynamicString='(Select Cast('''' AS XML).value(''xs:base64Binary(sql:column("'+ #PictureDateFieldName + '"))'', ''VARBINARY(MAX)'') FROM ScanIT_tblProjektbilder Where ID='''+ #PicID +''')'
creates this string:
(Select Cast('' AS XML).value('xs:base64Binary(sql:column("ImportPictureData"))', 'VARBINARY(MAX)') FROM ScanIT_tblProjektbilder Where ID='105')
DECLARE #ImageData VARBINARY(max);
select #ImageData = (Select Cast('' AS XML).value('xs:base64Binary(sql:column("ImportPictureData"))', 'VARBINARY(MAX)') FROM ScanIT_tblProjektbilder Where ID='105')
When I assign this string as a hardcopy to the variable #ImageData I do not get any error, if I am going to assign the variable #sqlDynamicString to the variable #ImageData like
select #ImageData = #sqlDynamicString
I get an
error 257: Implicit conversion from datatype 'VARCHAR' to 'VARBINARY(MAX)' is not allowed. Use CONVERT-Function
what is going wrong here??
Even using convert iso cast I get the same error.
Thanks
Execute the code in #sqlDynamicString,store the result in a temp table and then assign to your varbinary variable.
create table #temp
(
imageData varbinary(max)
)
insert into #temp
exec #sqlDynamicString
select #ImageData=(select imageData from #temp)
I was recommended the following stored procedure to audit a login table.
CREATE PROCEDURE ApplicationLogin
#Username NVARCHAR(255),
#IpAddress NVARCHAR(255)
AS
BEGIN
DECLARE #UserID INT;
BEGIN TRANSACTION;
SET #UserID = (SELECT UserID FROM User WHERE Username = #Username);
IF #UserID > 0
BEGIN
UPDATE User
SET LastLogin = GETDATE()
WHERE UserID = #UserID;
END
INSERT INTO UserLogger (Username, UserID, TimeStamp)
VALUES (#Username, #UserID, #Timestamp);
COMMIT TRANSACTION;
SELECT #UserID
END
However I can't make it work for some syntax errors that I can't figure out.
The User table looks like this:
CREATE TABLE [dbo].[User]
(
[UserID] [INT] IDENTITY(1,1) NOT NULL,
[UserName] [VARCHAR](50) NOT NULL,
[Enabled] [BIT] NOT NULL,
[LastLogin] [TIMESTAMP] NOT NULL,
PRIMARY KEY CLUSTERED ([UserID] ASC)
)
The Audit table looks like this:
CREATE TABLE [dbo].[UserLogger]
(
[UserID] [INT] IDENTITY(1,1) NOT NULL,
[UserName] [VARCHAR](50) NOT NULL,
[Name] [VARCHAR](100) NULL,
[TS] [TIMESTAMP] NULL,
[IpAddress] [NCHAR](10) NULL
) ON [PRIMARY]
I get an error
Cannot update a timestamp column
which I don't see why.
Any idea?
timestamp is not what you think it is. It is some sort of internal representation of the row address. Here is an explanation.
Use datetime or datetime2 to fix your problem.
This is made all the more confusing, because CURRENT_TIMESTAMP doesn't return a timestamp.
I have table User with n columns that stores user information in it.
I have another table User_Edit_Changes that I use to temporarily store changes to table User in it so that after admin confirmation I update the actual table User with new values.
In table User_Edit_Changes, I stored which user column requested for update and what is new value for that. How to write a dynamic query to get just changed value columns and new value from User_Edit_Changes and update the User table?
here is my sample create table command ,
teacher stores infos,
Tbl_ProfessorRequest stores edit change request,
Tbl_ProfessorEditInfoFields stores which fileds teacher request to edit

I'd say you have 3 options:
Handle the logic of updates outside the database, in what ever your application is built with. That's most likely the easiest way, since this kind of dynamic handling is not what databases are good at.
Build a dynamic SQL clause based on the contents of User_Edit_Changes. Loop through the changes in the table, construct an update statement into a variable and use sp_executesql to execute it. With cursor the code should be something like this:
set #params = N'#NewValue varchar(100)'
fetch next from yourcursor into #FieldName, #NewValue
while ##FETCH_STATUS = 0 begin
set #sql = 'update User set ' + #FieldName + ' = #NewValue'
exec sp_executesql #sql, #params, #NewValue = #NewValue
fetch next from yourcursor into #FieldName, #NewValue
end
Create static SQL statements for updating each of the columns. You can build something like this:
update U
set U.UserName = C.NewValue
from
User U
join User_Edit_Changes C on U.UserId = C.UserId
where
C.FieldName = 'UserName'
For this you of course need to have similar statements for each of your columns. You could build one massive update query with pivot or max+case, but handling the old and new values gets pretty complex.
i have the following type:
CREATE TYPE [dbo].[locationTable] AS TABLE(
[location_id] [varchar](100) NULL,
[name] [nvarchar](100) NULL,
[address] [varchar](100) NULL,
[latitude] [varchar](100) NULL,
[longitude] [varchar](100) NULL,
[distance] [varchar](100) NULL,
[state] [varchar](100) NULL,
[sub_cat] [varchar](100) NULL,
[idCat] [varchar](100) NULL,
[icon_link] [varchar](100) NULL,
[checkinsCount] [int] NULL
)
GO
and i'm passing a table as parameter having the above type to a stored procedure... but i need to delete some rows from this table in my stored procedure but i keep getting that it cannot be modified.... sql is always requesting to define the table as readonly and in this case i can not modify
A table parameter to a stored procedure must be readonly. MSDN says:
Note that the READONLY keyword is required for declaring a table-valued parameter.
You can solve this dilemma by copying the content to a local table variable. For example:
if exists (select * from sys.procedures where name = 'TestProc')
drop procedure TestProc
if exists (select * from sys.types where name = 'TestType')
drop type TestType
go
create type TestType as table (id int, name varchar(20))
go
create procedure dbo.TestProc
#par TestType readonly
as
declare #t TestType
insert #t select * from #par
delete #t where id = 2
select * from #t
go
declare #p1 TestType
insert #p1 values (1,'a'), (2,'b'), (3,'c');
exec dbo.TestProc #p1
I have a Microsoft SQL Server R2 2008. And i see it first time in my life.
I have sql procedure:
DECLARE #RC int
DECLARE #Id uniqueidentifier
DECLARE #Segment_ID uniqueidentifier
DECLARE #SDate datetime
DECLARE #EDate datetime
DECLARE #withBig bit
DECLARE #withKm bit
DECLARE #withGeo bit
DECLARE #withDescr bit
-- TODO: задайте здесь значения параметров.
EXECUTE #RC = [Request_BusStation]
#Id
,#Segment_ID
,#SDate
,#EDate
,#withBig
,#withKm
,#withGeo
,#withDescr
GO
How i understand its just calling of procedure not thetself. But procedure too bit to copy it here.
AND have a table:
CREATE TABLE [BusStation](
[Id] [uniqueidentifier] NOT NULL,
[Segment_ID] [uniqueidentifier] NOT NULL,
[Dist] [decimal](18, 4) NOT NULL,
[Kod_Spr012] [smallint] NOT NULL,
[Square] [decimal](18, 6) NULL,
[OperationStartDate] [date] NULL,
[BallanceCost] [decimal](18, 6) NULL,
[DepreciatedCost] [decimal](18, 6) NULL,
[ChargesNorm] [decimal](18, 6) NULL,
[DocumentName] [varchar](100) NULL,
[DocumentNum] [varchar](100) NULL,
[DocumentDate] [date] NULL,
[Authority] [varchar](100) NULL,
[Kod_Spr091] [smallint] NOT NULL,
[HasWaysideStop] [bit] NOT NULL,
[HasLanding] [bit] NOT NULL,
[HasSpeedTransitArea] [bit] NOT NULL,
[LenSpeedTransitArea] [decimal](18, 6) NULL,
[YearBuilt] [smallint] NULL,
[YearMajorOverhaul] [smallint] NULL,
[Kod_Spr019] [smallint] NOT NULL,
[TechCond] [varbinary](max) NULL,
[LandCont] [varbinary](max) NULL,
[LandContDate] [date] NULL,
[LandContStartDate] [date] NULL,
[LandContEndDate] [date] NULL,
[Kod_Spr120] [smallint] NULL,
[E_Date_Begin] [datetime] NOT NULL,
[E_Date_End] [datetime] NULL,
[E_Date_Stop] [datetime] NULL,
Now i want to call this procedure for each row of table.
Its possible?
Yes, you can use a cursor that selects all the rows in the table and iteratively calls the stored procedure.
I would suggest that you may have a design issue before going down that route though. If the stored procedure needs to be called for every row in the table, you may be able to write a stored procedure that simply does what your current sp does to all the rows instead of a single row operation.
You have not provided what the sp is doing so I can only speculate here.
As mentioned in my comment, the only way I would know how to do that is using a CURSOR. Here is some sample code (untested of course):
DECLARE #ID INT
DECLARE #Segment_ID uniqueidentifier
DECLARE #getAccountID CURSOR
SET #BusStationCursor = CURSOR FOR
SELECT Id, Segment_ID --(etc: all the fields you need)
FROM BusStation
OPEN #BusStationCursor
FETCH NEXT FROM #BusStationCursor INTO #ID, #Segment_ID
WHILE ##FETCH_STATUS = 0
BEGIN
--CALL YOUR SP HERE
PRINT #ID
PRINT #Segment_ID
FETCH NEXT FROM #BusStationCursor INTO #ID, #Segment_ID
END
CLOSE #BusStationCursor
DEALLOCATE #BusStationCursor

Good luck.
