Set A Variable To Datetime And Time To Exact Milliseconds In SQL Server In Stored Procedure AS A Single String
Nov 1, 2007
I need to set a variable to datetime and time to exact milliseconds in SQL server in stored procedure.
Example:
set MyUniqueNumber = 20071101190708733
ie. MyUniqueNumber contains yyyymmddhhminsecms
Please help, i tried the following:
1. SELECT CURRENT_TIMESTAMP; ////// shows up with - & : , I want single string as in above example.2.
select cast(datepart(YYYY,getdate()) as varchar(4))+cast(datepart(mm,getdate()) as char(2))+convert(varchar(2),datepart(dd,getdate()),101 )+cast(datepart(hh,getdate()) as char(2))+cast(datepart(mi,getdate()) as char(2))+cast(datepart(ss,getdate()) as char(2))+cast(datepart(ms,getdate()) as char(4))
This one doesnot display day correctly, it should show 01 but shows 1

Hi I'm new to MS SQL and trying to write a very small dynamic stored procedure which is giving me a headache.
What I have is:
CREATE PROCEDURE busy_report
@TableName varchar(255),
@reporteddate datetime=NULL
AS
if @reporteddate is null
select @reporteddate = CURRENT_TIMESTAMP
-- Create a variable @SQLStatement
DECLARE @SQLStatement varchar(255)
SET DATEFORMAT dmy
-- Enter the dynamic SQL statement into the
-- variable @SQLStatement
SELECT @SQLStatement = "SELECT vendor, reporteddate, count(vendor) FROM " +
@TableName + "WHERE reporteddate = ' "
+ @reporteddate + " '"
-- Execute the SQL statement
EXEC(@SQLStatement)
GO
The error I keep getting is:
Server: Msg 8114, Level 16, State 4, Procedure busy_report, Line 0
Error converting data type varchar to datetime.
Any ideas appreciated.
(Edit:)
I've also tried it this way:
CREATE PROCEDURE UK_busy_report
@TableName varchar(255),
@reporteddate datetime=NULL
AS
-- Create a variable @SQLStatement
DECLARE @SQLStatement varchar(255)
SELECT @reporteddate=CONVERT(datetime, @reporteddate)
IF @@ERROR <> 0 BEGIN
/* Do some error processing */
PRINT 'Error Occured' END
ELSE
-- Enter the dynamic SQL statement into the
-- variable @SQLStatement
SELECT @SQLStatement = "SELECT vendor, reporteddate, count(vendor) FROM " +
@TableName + "WHERE reporteddate = ' "
+ @reporteddate + " '"
-- Execute the SQL statement
EXEC(@SQLStatement)
GO
Which gives me the same error!
.logic.

I have a stored procedure called from ASP code, and when it is executed, the stored procedure takes in a date as an attribute.
But since the stored procedure call is really just a string in the code, it is taking in the value as a string. So in my stored procedure, I want to convert a string value to a date value.
Any idea how this is done?

Hello all.I am attempting to insert a row into a table with a datetime column:When the insert statement contains a value for the millisecond portionof the data time column: ie. {ts '2003-11-05 12:02:43:2960'}I get 'Syntax error converting datetime from string'When I insert a value like: {ts '2003-11-05 12:02:43'}with no millisecond value it succeeds.Any help would be appreciated.Thanks

I'm running into a constant issue of SQL Server modifying themillisecond part of a timestamp insert from another application. Theapplication inserts timestamp which includes a millisecond portion as astring (varchar). But when an SQL Server moves this data to anothertable (for reporting), the string is inserted in a datetime field, themillisecond field invariably changes by 1-2 milliseconds for everysingle data point inserted. Given the time critical nature of this data(to a millisecond), its almost impossible to avoid this other than toleave the data as string type. But this drives the analytical reportingfolks wild as report queries based on time criteria are getting messedup. Any ideas how to force SQL Server not to mess around with themillisecond value? Does this problem exist with SQL Server 2005 as well?

Problem about pass a big string (over 8000 characters) to a variable nvarchar(max) in stored procedure in SQL 2005!
I know that SQL 2005 define a new field nvarchar(max) which can stored 2G size string.
I have made a stored procedure Hellocw_ImportBookmark, but when I pass a big string to @Insertcontent , the stored procedure can't be launch! why?
create procedure Hellocw_ImportBookmark @userId varchar(80), @FolderId varchar(80), @Insertcontent nvarchar(max)

Hi,
I am trying to access a date column up to millisecond precession. So I cast date to as follows:
Code BlockCONVERT(varchar(23),CREATE_DATE,121)
I get millisecond part as a result of query but its 000?.
When I try to test the format by using getDate instead of DateTime column I get right milliseconds.
CONVERT(varchar(23),GetDate(),121) --Gives right milliseconds in return

I have a package variable that is a datetime... how am I able to set the time of that variable? In visual studio on the variables screen if I click on value it brings up a calendar control - I can't seem to edit the time portion of the variable.
When I first click open the variables window it will say 9/1/2006 12:00:00 AM - but as soon as I click on the value box the 12:00:00 AM part will disappear and I can't edit it. I've tried on someone elses PC as well to make sure there isn't something wrong with my visual studio
Ideas?

I want to execute a paramterized ADO insert command into a SQL Server DATETIME column without losing the milliseconds. I can accomplish this without parameters, but that isn't what I want. Any suggestions?
It is OK that DATETIME only has a resolution of 3.33 milliseconds.

Hi,
i am trying to add milliseconds to a time. For example if i have a time of 01:01:05:000 and i want to add 0.297 milliseconds to it i use the following simplified query
SELECT CONVERT(nvarchar(20), DATEADD(ms, 0.297, '00:01:05:000'), 14) AS Expr1
However instead of getting 01:01:05:0.297 i get 01:01:05:000. Can somebody please tell me what i am doing wrong.
Thanks in advance.

I've been working on a project to ensure that accross our entire data warehouse everything is at the same accuracy level as far as time - migrating everything to use the full hh:mis.mmm. Some places were using hh:mis:mmm (colon instead of decimal point) and many places not using milliseconds.
The SQL server portion went essentially without issue - however SSIS is not cooperating. For example I have data I am importing from a file that is in format: hh:mis (no milliseconds) that I need to compare to data from SQL (now containing full milliseconds) - matching on time ranges. Previously this was done by converting both to the "database time" datatype in SSIS and comparing. Now when converting the cTime to database time SSIS fails and complains "The value could not be converted because of a potential loss of data".
I don't want to lop off the milliseconds becuase that could create rounding errors.
I don't like it but the only option I can think of is keeping everything in string and comparing the strings... then I run into the issue of making sure to convert all sources of data into the exact same hh:mis:mmm format in text.
Is there an easier way? I know some people use "milliseconds since midnight" and so forth but that would require major reworking of the data warehouse and many packages.

Any better way to query SQL 2012 to display the code of a stored proc to a single line. I'm trying to write a script to insert the contents of the procs between my devestprod environments. So people can query a single table for any proc that is different between environments. At the moment I am using the syscomments view and the text column but the problem here is if you get a lengthy proc it cuts it up into multiple rows.
I can get around it by converting the text to a varchar(max) and outer joining the query, but as you can see by my code below I have to try and guess what the maximum number of rows I'm going to get back for my largest proc. If someone adds a new one that returns 8 rows I'm going to miss it with this query.
Select col1.[type],col1.[name],convert(varchar(max),col1.text) + isnull(convert(varchar(max),col2.Text),'')
+ isnull(convert(varchar(max),col3.Text),'')
+ isnull(convert(varchar(max),col4.Text),'')
+ isnull(convert(varchar(max),col5.Text),'')
+ isnull(convert(varchar(max),col6.Text),'')
+ isnull(convert(varchar(max),col7.Text),'')

declare @cmd varchar(1000)
select @cmd = 'select * from ' + @server + '.DATABASE.dbo.TableName where
TableDateField =' + @variableDateField + '
exec (@cmd)
I've tried converting both datetime fields to varchar fields and I still get syntax errors. Any suggestions?

I am not sure how to go about doing this. I have a record that has a start time of 1 am and a stop time of 9pm (same day for simplicity) and I want to know how many hours during a peek time and how many were not.
For example, the application starts and inserts into the data base the start time of 1am and then the user stops the app at 9pm. Lets say the peek hours are 1pm to 7pm. I know i can do a date diff function to get how long the app ran for but how can I get the amount of hours it ran during the peek time? I know there has to be some mathematical solution to this but it is escaping me at the moment. I want to do this over many records so a a cte or pivot table is the end solution for performance.

Hi,
I'm having problems with a stored procedure, that i'm hoping someone can help me with.
I have a table with 2 columns - Username (varchar), LastAllocation (datetime)
The Username column will always have values, LastAllocation may have NULL values. Example
Username | LastAllocation
------------------------
Greg | 02 October 2005 15:30
John | 02 October 2005 18:00
Mike | <NULL>
My stored procedure needs to pull back a user name with the following criteria:
If any <NULL> dates send username of first person where date is null, sorted alphabetically, otherwise send username of person with earliest date from LastAllocation
Then update the LastAllocation column with GETDate() for that username.
This SP will be called repeatedly, so all users will eventually have a date, then will be cycled through from earliest date. I wrote an SP to do this, but it seems to be killing my server - the sp works, but I then can't view the values in the table in Enterprise Manager. SP is below - can anyone see what could be causing the problem, or have a better soln?
Thanks
Greg

Hello all,
We have a domain where all computers are on GMT(Greenwitch Mean Time). We have an access front end that timestamps certain fields according to the client time that the program is running on, but we will be moving our client workstations off of GMT time and keep our SQL Server on GMT time, and want to keep the timestamps GMT.
So, I wanted to know if it was possible to create a stored procedure that gets the Server's time and returns it to the Access frontend for entry into the timestamp fields?
Or, if anyone has a better idea of how to get the time from the server to use on the clients, I would greatly appreciate it!!!

I'm new to SSIS, but have been programming in SQL and ASP.Net for several years. In Visual Studio 2005 Team Edition I've created an SSIS that imports data from a flat file into the database. The original process worked, but did not check the creation date of the import file. I've been asked to add logic that will check that date and verify that it's more recent than a value stored in the database before the import process executes.
Here are the task steps.
[Execute SQL Task] - Run a stored procedure that checks to see if the import is running. If so, stop execution. Otherwise, proceed to the next step.
[Execute SQL Task] - Log an entry to a table indicating that the import has started.
[Script Task] - Get the create date for the current flat file via the reference provided in the file connection manager. Assign that date to a global value (FileCreateDate) and pass it to the next step. This works.
[Execute SQL Task] - Compare this file date with the last file create date in the database. This is where the process breaks. This step depends on 2 variables defined at a global level. The first is FileCreateDate, which gets set in step 3. The second is a global variable named IsNewFile. That variable needs to be set in this step based on what the stored procedure this step calls finds out on the database. Precedence constraints direct behavior to the next proper node according to the TRUE/FALSE setting of IsNewFile.
If IsNewFile is FALSE, direct the process to a step that enters a log entry to a table and conclude execution of the SSIS.
If IsNewFile is TRUE, proceed with the import. There are 5 other subsequent steps that follow this decision, but since those work they are not relevant to this post.
Here is the stored procedure that Step 4 is calling. You can see that I experimented with using and not using the OUTPUT option. I really don't care if it returns the value as an OUTPUT or as a field in a recordset. All I care about is getting that value back from the stored procedure so this node in the decision tree can point the flow in the correct direction.
CREATE PROCEDURE [dbo].[p_CheckImportFileCreateDate]
/*
The SSIS package passes the FileCreateDate parameter to this procedure, which then compares that parameter with the date saved in tbl_ImportFileCreateDate.
If the date is newer (or if there is no date), it updates the field in that table and returns a TRUE IsNewFile bit value in a recordset.
Otherwise it returns a FALSE value in the IsNewFile column.
Example:
exec p_CheckImportFileCreateDate 'GL Account Import', '2/27/2008 9:24 AM', 0
*/
@ProcessName varchar(50)
, @FileCreateDate datetime
, @IsNewFile bit OUTPUT
AS
SET NOCOUNT ON
--DECLARE @IsNewFile bit
DECLARE @CreateDateInTable datetime
SELECT @CreateDateInTable = FileCreateDate FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName
IF EXISTS (SELECT ProcessName FROM tbl_ImportFileCreateDate WHERE ProcessName = @ProcessName)
BEGIN
-- The process exists in tbl_ImportFileCreateDate. Compare the create dates.
IF (@FileCreateDate > @CreateDateInTable)
BEGIN
-- This is a newer file date. Update the table and set @IsNewFile to TRUE.
UPDATE tbl_ImportFileCreateDate
SET FileCreateDate = @FileCreateDate
WHERE ProcessName = @ProcessName
SET @IsNewFile = 1
END
ELSE
BEGIN
-- The file date is the same or older.
SET @IsNewFile = 0
END
END
ELSE
BEGIN
-- This is a new process for tbl_ImportFileCreateDate. Add a record to that table and set @IsNewFile to TRUE.
INSERT INTO tbl_ImportFileCreateDate (ProcessName, FileCreateDate)
VALUES (@ProcessName, @FileCreateDate)
SET @IsNewFile = 1
END
SELECT @IsNewFile
The relevant Global Variables in the package are defined as follows:
Name : Scope : Date Type : Value
FileCreateDate : (Package Name) : DateType : 1/1/2000
IsNewFile : (Package Name) : Boolean : False
Setting the properties in the "Execute SQL Task Editor" has been the difficult part of this. Here are the settings.
General
Name = Compare Last File Create Date
Description = Compares the create date of the current file with a value in tbl_ImportFileCreateDate.
TimeOut = 0
CodePage = 1252
ResultSet = None
ConnectionType = OLE DB
Connection = MyServerDataBase
SQLSourceType = Direct input
IsQueryStoredProcedure = False
BypassPrepare = True
I tried several SQL statements, suspecting it's a syntax issue. All of these failed, but with different error messages. These are the 2 most recent attempts based on posts I was able to locate.
SQLStatement = exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
SQLStatement = exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
Parameter Mapping
Variable Name = User::FileCreateDate, Direction = Input, DataType = DATE, Parameter Name = 0, Parameter Size = -1
Variable Name = User::IsNewFile, Direction = Output, DataType = BYTE, Parameter Name = 1, Parameter Size = -1
Result Set is empty.
Expressions is empty.
When I run this in debug mode with this SQL statement ...
exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the following error message appears.
SSIS package "MyPackage.dtsx" starting.
Information: 0x4004300A at Import data from flat file to tbl_GLImport, DTS.Pipeline: Validation phase is beginning.
Error: 0xC002F210 at Compare Last File Create Date, Execute SQL Task: Executing the query "exec ? = dbo.p_CheckImportFileCreateDate 'GL Account Import', ?, ? output" failed with the following error: "No value given for one or more required parameters.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Task failed: Compare Last File Create Date
Warning: 0x80019002 at GLImport: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED.

This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "MyPackage.dtsx" finished: Failure.
When the above is run tbl_ImportFileCreateDate does not get updated, so it's failing at some point when calling the procedure.
When I run this in debug mode with this SQL statement ...
exec p_CheckImportFileCreateDate 'GL Account Import', ?, ? output
... the tbl_ImportFileCreateDate table gets updated. So I know that data piece is working, but then it fails with the following message.
SSIS package "MyPackage.dtsx" starting.

The IsNewFile global variable is scoped at the package level and has a Boolean data type, and the Output parameter in the stored procedure is defined as a Bit. So what gives?
The "Possible Failure Reasons" message is so generic that it's been useless to me. And I've been unable to find any examples online that explain how to do what I'm attempting. This would seem to be a very common task. My suspicion is that one or more of the settings in that Execute SQL Task node is bad. Or that there is some cryptic, undocumented reason that this is failing.
Thanks for your help.
