Compilation Error
Sep 30, 2004I'm trying to connect to an SQL database through my asp.net page and I'm getting an Compiler Error Message: BC30188: Declaration expected for the following codes:
DBConn= New OledbConnection("Provider=sqloledb;" _
DBInsert.Commandtext = "Insert Into GuestInfo" _
DBInsert.Connection =DBConn
DBInsert.Connection.Open
DBInsert ExecuteNonQuery()
What I'm trying to do is connect to the SQL database and input new information to the database.
This is the entire code for connecting and entering info into the database. The SQL Database's name is HMS. I'm stuck and I can't figure it out.
Dim DBConn as oledbConnection
Dim DBInsert As New oledbCommand
DBConn= New OledbConnection("Provider=sqloledb;" _
& "server=localhost;" _
& "Initial Catalog=HMS;" _
& "User id=sa;" _

Prevent SP Compilation
Jul 20, 2005Hi,I'm using SQL Server 2000 MSDE on a laptop running Windows XP.I have a couple of SP's that that quite some time to compile. So I waswondering: is there any way to have the database *not* recompile them everytime after a reboot?BOL says: "As a database is changed by such actions as adding indexes orchanging data in indexed columns, the original query plans used to accessits tables should be optimized again by recompiling them. This optimizationhappens automatically the first time a stored procedure is run afterMicrosoft® SQL ServerT 2000 is restarted."Now the SQL Server is restarted a lot, because laptops don't have endlessbatteries <g>Cheers,Bas

Jul 20, 2005Using small stored procs or sp_executesql dramatically reduces the number ofrecompiles and increases the reuse of execution plans. This is evident fromboth the usecount in syscacheobjects, perfmon, and profiler. However I'm ata loss to determine what causes a compilation. Under rare circumstances theusecount for Compiled Plan does not increase as statements are run. Seemsto correspond to when there is no execution plan. It would seem to me thatcompilation is a resource intensive task that if possible (data and schemaare not changing) should be held to a minimum.How does one encourage the reuse of compile plans?Is this the same as minimizing compilation?Looks like some of this behavior is changing in SQL 2005....Thanks,Danny

Hi,
We are using .Net 2.0 for developing our application, All the file in this application are source safed, Whenever we do modification in the code it take longer time to build approax it takes around 2 min to display the default page (login page).
Please do send out your suggestions to reduce the time take for the build, is there any setting need to be done in IDE to make the build process much faster.

Compilation Of Stored Procs
Aug 10, 2006 Hi,
I would like to know if the execution plans of stored procs also get migrated when we do migration to 2005 from 2000 using attachdetach method or we will need to re-run the stored procs?
The thing is when I am running the Stored procs in 2005, its performing really slow in first run.
Any help in his regard is highly appreciated.

SP Compilation Confirmation Message?
Nov 13, 2006How can we say whether the SP is successfully compiled or not if we are compiling it on the server as a part of the TSQL script since it does not throw any message like ORACLE does.
In oracle, system will let you know whether the the procedure is successfully complied or not?

SQL Compilation And Execution Plan
Jul 5, 2007Hi all,
I€™m having a test regarding to the image data type. The test program is written with sql native api and just update the image data type column, but I looked the SQL Compilations/sec and Batch Requests/sec counters in SQLServer:QL Statistics using Perfmon, both values are almost the same. It seemed whenever the stored procedure is called, SQLServer compiles it and makes execution plan again. But when I had a test without image data type, SQL Compilation/sec was 0. SQL version is Microsoft SQL Server 2005 - 9.00.3054.00 (Intel X86) (Build 2600: Service Pack 2).
Is SQL server working the way expected or am I missing something?

View 1 Replies View RelatedSSIS Package Compilation And Execution
Mar 6, 2007I am wondering something, once we've created a job that executes a package at a given time interval, does that package get recompiled each time the job spins up and executes the package? Or is the package compiled once and then that compiled code is executed each run after the first run?
What I'm seein is this; I have a package that reads data from flat text files and then dumps that data into the database. The package will take 3 minutes to execute when executing on a single file, but when it's looping through ~50 files, it will take ~30 minutes to execute, that is less than a minute per file. Why is this?
Hopefully I'm just forgetting something and not setting a checkbox or radio button somewhere. The job is set up as an SSIS job, not as a command line job.
Thanks in advance for any help you can give me.

DTS To SSIS Conversion (ActiveX Script Has Compilation Errors)
Oct 12, 2015I am re-writing old DTS packages(from sql 2005) to convert them to SSIS packages(sql 2014) and in one of the script task, the old activex script does not run.
The script is :
'************************

Function Main()
mydate = now()
yrs = ""

mth = Month(mydate) - 1
yrs = Right(Year(mydate), 4)

Ignore Compilation Errors For Creation Of Stored Procedures
Apr 2, 2008I have an application that is moving from an home made full text search engine to using the full text indexing engine of SQL 2005. I have a stored procedure that I want to behave as:
check documents table to determine whether a full text index for SQL's full text engine has been created.
If it has not, query the documentText table (which is the table for my in-house full text search)
If it has, use the full text indexing engine
My problem is that compilation of the TSQL to create the stored procedure fails when the full text index has not already been created with the followign error:
Msg 7601, Level 16, State 2, Procedure My_FullTextSearch, Line 0
Cannot use a CONTAINS or FREETEXT predicate on table or indexed view 'Documents' because it is not full-text indexed.
In my test lab, I tried:
1. creating the full text index
2. creating the stored procedure
3. deleting the ful text index
which gets me to the desired end result of having a stored procedure that can determine whether or not the full text index has been created yet (the procedure works in this state). But I creating this index as part of this stored procedure creation in production is not an option.
My question - Can I somehow tell SQL to ignore the compilation errors it encounters while creating this stored procedure? If not, is there some other way to create this "smart" stored procedure?
Here's a code snippet stripped down to the bare minimum to generate the error:
CREATE PROCEDURE [My_FullTextSearch]
@Term VarChar(1000)
AS
BEGIN
SET NOCOUNT ON;
IF NOT OBJECTPROPERTY(OBJECT_ID('Documents'), 'TableHasActiveFulltextIndex')=1
BEGIN
Select [DocumentID]
from [DocumentText]
where [Term] like '%' + LTRIM(@Term) + '%'
END
ELSE
BEGIN
Select [key] from FREETEXTTABLE(Documents, Contents, @Term)
END
END
Stored Procedure Compilation Question: Doing Disparate Things In Aproc
Dec 8, 2007To minimize the very large number of stored procedures typicallyassociated with an application, I have gotten in the habit ofcombining a select, insert, update, and delete all in one procedure,and passing an argument to indicate which to use. (I use defaultvalues for all input params to avoid having to declare them forselects and deletes.) So I'll have just one PersonAdmin proc insteadof PersonGet, PersonInsert, PersonUpdate, and PersonDelete procsWhile this is nice for housekeeping, I wonder what the compiler doeswith such an architecture,and I fear the worst. The select returns arecordset; the others don't.Is this a bad idea?If it is, I really wish SQL would permit some sort of user folderstructure in the proc list.

How To Convert UTC Time (retrieved From SQL) To Local Time In Reporting Services Based On Time Zone
Aug 7, 2007
Hi all,
I have created a report in SSRS 2005 which is being viewed by users from different Time Zones.
I have a dataset which has a field of type datetime (UTC). Now I would like to display this Date according to the User Time Zone.
For example if the date is August 07, 2007 10:00 AM UTC,
then I would like to display it as August 07, 2007 03:30 PM IST if the user Time Zone is IST.
Similarly for other Time Zones it should display the time accordingly.
Is this possible in SSRS 2005?
Any pointers will be usefull...
Thanks in advance

SQL 2012 :: Accurate Sorting Data Each Time With Millions Of Records Without Time Field?
Apr 25, 2014Sample Table

It seems to work fine with one million records.
Each primary key is unique, but the begindate is non-unique, and i guess even if i use datetime2 and add nanoseconds, from what i have read, there is a chance that i could have a duplicate datetime since the date is imported via XML from multiple sources.

It Takes A Long Time To Insert The First Record Each Time When The Program Start
Dec 15, 2006I am using VS2005 (VB) to develop a PPC WM5.0 Program. And I am using SQLCE 3.0. My PPC Hardware is in 400MHz.
The question is when the program try to insert the first record into sdf database after each time the program started. It takes a long time. Does anyone know why and how can I fix it?
I will load the whole database into a dataset when the program start and do all the "Insert", "Update", "Delete" in this dataset and fill it into database after each action.
cn.Open()
sda = New SqlCeDataAdapter(SQL, cn) 'SQL = Select * From Table
scb = New SqlCeCommandBuilder(sda)
sda.Update(dataset)
cn.Close()
I check the sda.update(), it takes about 0.08s for filling one record into database normally. But:
1. Start the PPC Program
2. Load DB into dataset
3. Create a ONE new record in dataset
4. Fill back to DB
When I take this four steps everytime, the filling time is almost 1s or even more!
Actually, 0.08s is just a normal case. Sometimes, it still takes over 1s to filling back a dataset which only inserted one record when the program is running. (Even all inserted records are exactly the same in data jsut different in the integer key)
However, when I give up the dataset and using the following code:
cn.Open()
Dim cmd As New SqlCeCommand(SQL, cn) ' I have build the insert SQL before (Insert Into Table values(XXXXXXXXXXXXXXX All field)
cmd.CommandType = CommandType.Text
cmd.ExecuteNonQuery()
cn.Close()
StartTime = Environment.TickCount
I found that it is still the same that the first inserted record takes more time, but just about 0.2s. And the normal insert time is around 0.02s. It is 4 times faster!!!

Problem With Getdate() In Transaction Takes The Insert Time Instead Of The Commit Time
Nov 12, 2007Hi,
We need to select rows from the database that have been recently inserted/updated. We have a main primary table (COMMIT_TEST) and a second update table (COMMIT_TEST_UPDATE). The update table contains the primary key and a LAST_UPDATE field which is a datetime (to tell us when an update occurred). Triggers on the primary table are used to populate the update table.
If we insert or update the primary table in a transaction, we would expect that the datetime of the insert/update would be at the commit, however it seems that the insert/update statement is cached and getdate() is executed at the time of the cache instead of the commit. This causes problems as we select rows based on LAST_UPDATE and a commit may occur later but the earlier insert timestamp is saved to the database and we miss that update.
We would like to know if there is anyway to tell the SQL Server to not execute the function getdate() until the commit, or any other way to get the commit to create the correct timestamp.
We are using default isolation level. We have tried using getdate(), current_timestamp and even {fn Now()} with the same results. SQL Queries that reproduce the problem are provided below:
/* Different functions to get current timestamp €“ all have been tested to produce the same results */
/*
SELECT GETDATE()
GO
SELECT CURRENT_TIMESTAMP
GO
SELECT {fn Now()}
GO
*/
/* Use these statements to delete the tables to allow recreate of the tables */
/*
DROP TABLE COMMIT_TEST
DROP TABLE COMMIT_TEST_UPDATE
*/
/* Create a primary table and an UPDATE table to store the date/time when the primary table is modified */
CREATE TABLE dbo.COMMIT_TEST (PKEY int PRIMARY KEY, timestamp) /* ROW_VERSION rowversion */
GO
CREATE TABLE dbo.COMMIT_TEST_UPDATE (PKEY int PRIMARY KEY, LAST_UPDATE datetime, timestamp ) /* ROW_VERSION rowversion */
GO
/* Use these statements to delete the triggers to allow reinsert */
/*

Any help would be appreciated, we understand we could make changes to the application/database to approximate what we need, but all the solutions have identified suffer from possible performance issues, or could still lead to missing deals (assuming the commit time is larger than some artifical time window).

We are using SQL Server 2008 as our database and use Access as a GUI. I am looking to create a form in Access where employees can access their time card and request changes from management. I want to use the format from the attached screen shot for the form. I pretty much know how to do it all, the only point of complication is trying to figure out the easiest way to get the transaction punch record data on employee_punch_record into a format where I can easily populate the form in the horizontal format you see in the screen shot.
I am not super strong in SQL, but figure I can do it using a formatting table of some sort. quick and easy way to move transaction records into a more horizontally oriented record?
A Time Series Prediction Was Requested With A Start Time Further In The Past Than The Internal Models Of The Mining Model
Feb 19, 2008Hi all,
I have a very simple time series model which processing works fine without any problem. However when I run the following query
SELECT
[TimeSeries].[PriceChange],
[TimeSeries].[Symbol],
PredictTimeSeries(PriceChange, -3, 2)
From
[TimeSeries]
WHERE
[TimeSeries].[Symbol] = 'x'
I get the following error:
TITLE: Microsoft SQL Server 2005 Analysis Services
------------------------------
Error (Data mining): A time series prediction was requested with a start time further in the past than the internal models of the mining model, TimeSeries, specified in the HISTORIC_MODEL_GAP and HISTORIC_MODEL_COUNT parameters can process.
The following is the excerpt of the minding model script related to the two parameters:
<AlgorithmParameters>
<AlgorithmParameter>
<Name>MISSING_VALUE_SUBSTITUTION</Name>
<Value xsi:type="xsdtring">Previous</Value>
</AlgorithmParameter>
<AlgorithmParameter>
<Name>HISTORIC_MODEL_GAP</Name>
<Value xsi:type="xsd:int">1</Value>
</AlgorithmParameter>
<AlgorithmParameter>
<Name>HISTORIC_MODEL_COUNT</Name>
<Value xsi:type="xsd:int">10</Value>
</AlgorithmParameter>
</AlgorithmParameters>
These HISTORIC_MODEL_GAP (1) and HISTORIC_MODEL_COUNT (10) should accommodate PredictTimeSeries(PriceChange, -3, 2). Could anyone shed some light on this?
Reporting Services :: SSRS Loses Ability To Delegate User Credentials To Database Time To Time?
Apr 30, 2015we have problems with our SQL Reporting Service 2012 (SSRS) server . We have setup Kerberos delegation between SSRS and the database server (SQL Server Always-on cluster) so users are authenticated down to the database. The issue occurs from time to time that SSRS loses the ability to delegate the user credentials to the database. At this point in time the Report Server logs contain rejected database connections because of ANONYMOUS logon. After restarting SSRS the problem is gone.
View 2 Replies View RelatedHelp Writing Query (find The Entry With The Closest Time Given A Time)
May 26, 2005Hi,
I have a table which has a few fields, one being "datetime_traded". I need to write a query which returns the row which has the closest time (down to second) given a date/time. I'm using MS SQL.
Here's what I have so far:
Code:
select * from TICK_D
where datetime_traded = (select min( abs(datediff(second,datetime_traded , Convert(datetime,'2005-05-30:09:31:09')) ) ) from TICK_D)
But I get an error - "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.".
Does anyone know how i could do this? Thanks a lot for any help!
Optimization Advice (CPU Time = 15203 Ms, Elapsed Time = 8114 Ms.)!!
Aug 17, 2007Ok, so I have some horribly convuluted SQL that I would love to optomize. I'm not happy leaving it in it's current state, that's for sure!
I'm currently working on our test bed servers, so obviously my stats are out because of the "crap-ness" (yes, that's the technical term) of the hardware, but still, it should NEVER need to take this long!!
Basically, the issue arises in the nasty join to the career table (one employee can have multiple career lines). Just to make things complicated, employees can have any number of career records on any given date, these can even be input for future career events. The following SQL picks out the latest-current career date for each employee based on the career_date being <= GetDate() and the date of entry for this date being the greatest.
E.g.
career_date | datetime_created
2009-01-01 | 2006-05-05 13:55:21.000
2007-01-01 | 2006-05-05 13:54:18.000
2007-01-01 | 2006-05-05 13:52:55.000
From the above we want to return
2007-01-01 | 2006-05-05 13:54:18.000

Oh judt to point out that "employee" is a view on the "Table 'people'."
EDIT: I know it's pointing out the obvious, but I'm pulling out the managers "DN" from AD_Import based on the manager_number and employeeNumber matching.
