Getting Data From Dataset Back Into Database

Sep 7, 2006

I'm new at this so I apologize in advance for my ignorance.

I'm creating a website that collects dates in a calendar control (from Peter Blum). When the page containing the control loads it populates the calendar with dates from the database (that have previously been selected by the user). The user then can delete existing dates and/or add new dates.

I create a dataset when the page loads and use it to populate the calendar. When the user finishes adding and deleting dates in the calendar control I delete the original dates from the dataset and then write the new dates to the dataset. I then give execute the data adapter update command to load the contents of the dataset back into the database. This command involves using parameterized queries. For example the Insert command is:

Dim cmdInsert As SqlCommand = New SqlCommand("INSERT INTO Requests VALUES(@fkPlayerIDNumber, @RequestDate, @PostDate, @fkGroupID)", conn)

cmdInsert.Parameters.Add(New SqlParameter("@fkPlayerIDNumber", SqlDbType.Int))

cmdInsert.Parameters.Add(New SqlParameter("@RequestDate", SqlDbType.DateTime))

cmdInsert.Parameters.Add(New SqlParameter("@PostDate", SqlDbType.DateTime))

cmdInsert.Parameters.Add(New SqlParameter("@fkGroupID", SqlDbType.Int))

da.InsertCommand = cmdInsert

The update command is:

da.Update(ds, "Requests")

When I run the program I get the following error:

Parameterized Query '(@fkPlayerIDNumber int,@RequestDate datetime,@PostDate datetime,' expects parameter @fkPlayerIDNumber, which was not supplied.

I've used debug print to establish that the table in the dataset contains what it should.

I would be more than grateful for any suggestions.

Write A Date Back To A Table In An Expression

Mar 12, 2008

Help,

I have a package that maps the current getdate to a variable.

I then want to be able to write that variable back to a table using a sql task using the following expression:

"INSERT INTO CONTROL_BATCH_HEADER VALUES (
" + (DT_STR, 10, 1252) @[Control::intAdtBatchId] + ",
'" + @[Control::strSubjectArea] + "',
convert(datetime, '" + (DT_STR, 30, 1252) @[Control::dteRunDate] + "',131))"


The problem is the date is being written back in the wrong format. I've tried changing the mask to 121 but the month is being written as the day.

Help, how can I make this work regardless of the locals. In oracle I would just put a to_char(date,'dd-mm-yyyy') but not sure what to do here.

Thanks for your help

Tables Not Being Written Back To DB From Dataset. I'm Going Nutz!

Sep 26, 2006

ok. the problem: some tables are empty, so i can't be sure why some are updating at the DB and some arent.
I have manually picked thru every line of the xml that i'm reading into the dataset here, and it is fine, data is all valid and everything.
the tables i'm most worried about are bulletins and surveys, but they all have to be imported from my upload, the code steps thru just fine and I've been thru it a million times.

Transact SQL :: Insert Records And Write Back Identity Value

Jun 19, 2015

I'm trying to insert records into "holding" table and write back identity column value (Entry_Key) to the original table. So my setup is I have two tables; tblEWPBulk and tbleFormsUploadEWP. Users will enter records into tblEWPBulk and use BatchID to group records, once batch entry has been completed (usually less than 30 records) user will click on UploadAll button and insert records (not all fields) into tbleFormsUploadEWP. One record in tblEWPBulk can be sent multiple times to the holding table but tblEWPBulk will need to have latest Entry_Key captured. Records are sent from holding table to DB2 z/VSE using SQL stored procedure and based on certain logic records are marked uploaded or certain error capture... that part works fine.

So for example I want to send 

BatchID, AccountNumber, Period, ReceiveDate, AccountType, ReturnType, NetProfitOrLoss, TaxCredit FROM tblEWPBulk to the holding table and write back Entry_Key (identity column) back to the record in tblEWPBulk (field called UploadEntryKey). As I said one record could be sent to the holding table multiple times until uploaded or deleted and UploadEntryKey always needs to be updated so that when results are processed response from the DB2 can be inserted into table and presented to the user.

No foreign key relationship exists since records in the holding table get sent to the archive table and table is truncated and entry_key starting value reset back to 2000... just some DB2 restrictions.

Analysis :: How To Block Writing In Total Cells When Use Excel And Write Back

Nov 16, 2015

I have a cube with a partition configures in write back.

Users in Excel need to see the totals of the line. Unfornately they have the bad idea to write in this cell sometimes and not in the leaf cells.

As there is some MDX code behind in the weight expression field, we got some weird values : one is negative and others ARe 10 times the initial value in the total. So it's very dangerous.

How can we block the writing in this totals cells ?

Problem With Update When Updating All Rows Of A Table Through Dataset And Saving Back To Database

Feb 24, 2006

Hi,
I have an application where I'm filling a dataset with values from a table. This table has no primary key. Then I iterate through each row of the dataset and I compute the value of one of the columns and then update that value in the dataset row. The problem I'm having is that when the database gets updated by the SqlDataAdapter.Update() method, the same value shows up under that column for all rows. I think my Update Command is not correct since I'm not specifying a where clause and hence it is using just the value lastly computed in the dataset to update the entire database. But I do not know how to specify  a where clause for an update statement when I'm actually updating every row in the dataset. Basically I do not have an update parameter since all rows are meant to be updated. Any suggestions?
SqlCommand snUpdate = conn.CreateCommand();
snUpdate.CommandType = CommandType.Text;
snUpdate.CommandText = "Update TestTable set shipdate = @shipdate";
snUpdate.Parameters.Add("@shipdate", SqlDbType.Char, 10, "shipdate");
string jdate ="";
for (int i = 0; i < ds.Tables[0].Rows.Count - 1; i++)
{
jdate = ds.Tables[0].Rows[i]["shipdate"].ToString();
ds.Tables[0].Rows[i]["shipdate"] = convertToNormalDate(jdate);
}
da.Update(ds, "Table1");
conn.Close();
 
-Thanks

Having Difficulty Setting Back Up To Back Up File Wihout Datetime Stamp SQL 2K

Apr 24, 2007

Hello,I'm trying to create a simple back up in the SQL Maintenance Plan that willmake a single back up copy of all database every night at 10 pm. I'd likethe previous nights file to be overwritten, so there will be only a singleback up file for each database (tape back up runs every night, so each daysback up will be saved on tape).Every night the maintenance plan makes a back up of all the databases to anew file with a datetime stamp, meaning the previous nights file stillexists. Even when I check "Remove files older than 22 hours" the previousnights file still exists. Is there any way to create a back up file withoutthe date time stamp so it overwrites the previous nights file?Thanks!Rick

Mirroring :: Principal Database Get Role Back After Being Back On Line

May 14, 2015

New to Database Mirroring and I have a question about the Principal database server. I have a Database Mirroring setup configured for High-safety with automatic fail over mode using a witness.

When a fail over occurs because of a lost of communication between the principal and mirror, the mirror server takes on the roll of Principal. When communication is returned to the Principal server, at some point does the database that was the previous Principal database automatically go back to being the Principal server?

SQL Server 2008 :: Populate One Dataset In SSRS Based On Results From Another Dataset Within Same Project?

May 26, 2015

I have a report with multiple datasets, the first of which pulls in data based on user entered parameters (sales date range and property use codes). Dataset1 pulls property id's and other sales data from a table (2014_COST) based on the user's parameters. I have set up another table (AUDITS) that I would like to use in dataset6. This table has 3 columns (Property ID's, Sales Price and Sales Date). I would like for dataset6 to pull the Property ID's that are NOT contained in the results from dataset1. In other words, I'd like the results of dataset6 to show me the property id's that are contained in the AUDITS table but which are not being pulled into dataset1. Both tables are in the same database.

Integration Services :: Perform Lookup On Large Dataset Based On A Small Dataset

Oct 1, 2015

I have a small number of rows in a dataset, Table 1.  There is a CLOB on a large dataset, Table 2.  They join on a PK.  I would like to retrieve this CLOB and add it to the data flow for Table1.  In short I want to emulate the following:

Table 1:  Small table without CLOB, 10 rows. 
Table 2: Large table with CLOB, 10,000,000 rows

select CLOB
from table2
where pk = (select pk from table1)

I want this to return the CLOBs for the small number of rows in Table 1.  The PK is indexed obviously so it should be a fast look up.

Table 1 and Table 2 live on different Oracle databases.  How do I perform this operation efficiently in SSIS?  It seems the Lookup and Merge Join wont do this.

Rolling Back SQL Server 2005 Databases Back To SQL Server 2000

Sep 22, 2006

Does anybody know of a way to rollback SQL Server 2005
databases back to SQL Server 2000? Is there a way of doing it without
resorting to Copy Database Wizard? I love to find a way of attaching a SS 2005 database
to a SS 2000 instance without any issues.



I recently upgraded to SS 2005 and I am very unhappy with the SS 2005 and I
want to rollback to SS 2000, which was a lot more stable. I am having
several major issues that are affecting my whole company's day-to-day
operations and the managers are not happy. Some of the issues include
night time batch running very sluggish for no apparent reason. This is a
biggest problem because it only occurs once or so a week and causes a disturbance
with the daily activities when the night time processing isn€™t completed on
time. The rest of the time, the batch processing runs great, even a little better then on SS 2000. I
don't believe it is a matter of my application needing to be retuned because if
that was the case, then why isn't it running sluggish every night? Also,
it's never the same day that the sluggish behavior occurs. If it was occurring
on the same night, then I would have something to investigate within our
application, but it doesn't. Another issue that I am having involves a
night time job that restores a copy of the production database to the Data
Warehouse server to be used for updating the data warehouse. Again, most
of the time it runs great (~2 1/2 hours), but once or twice a week, it goes
stupid and takes 6 1/2 hours for no apparent reason. Again, it is not happening
the same day either, which could give me something to invesigate. On SS 2000, this same job ran flawlessly. Never I did I run into situation that the
database restoration took that long to run. Even another issue involves a SQL Server Agent Job that was put into suspended
state. What's a suspended state and how can I get it out of suspended
state? I can find no information about suspended state in BOL. I
did a Google and nothing came up. If this suspended state was put
in for security reasons, great, but then tell me how I can remove the suspended
state. I am also not happy with the
fact that I can't get accurate information about the queries that are actively
running at that particular moment. In SS 2000, when I noticed high CPU
usage on the server, I would run the sp_who2 active stored proc and it would
show me all the active thread and how much CPU it was consuming. I would
then find the running threads with the highest CPU numbers and investigate the
query and see if we could improve it. Now in SS 2005, I get in the same
situation and run the sp_who2 stored proc, and there is no smoking gun.
All of the active threads are showing very little CPU usage, which I am very
suspect of. What the heck happen to sp_who2? I looked at some of
the other ways of looking at running processes (i.e... sys.sysprocesses) and
they don't appear to be giving the information that I need.



I am very unhappy and I just want to roll back to SS 2000 and wait a couple of
years before I upgrade to SS 2005.

Filter One One Dataset With Values In Another Dataset?

Dec 19, 2006

Hi,

I have two datasets in my report, D1 and D2.

D1 is a list of classes with classid and title

D2 is a list of data. each row in D2 has a classid. D2 may or may not have all the classids in D1. all classids in D2 must be in D1.

I want to show fields in D2 and group the data with classids in D1 and show every group as a seperate table. If no data in D2 is available for a classid, It shows a empty table.

Is there any way to do this in RS2005?

I need to call this method. But my problem is how pass parameter ?
I see the tab Param but it isn't work as I wait,... maybe I do a mistake...

I want that statTime and endTime are select by the user via a calendar for example...
now idIndicator and idEq was result of an other dataSet from a xml datasource...

But I don't how integrate dynamically... I try to enter a parameter via the param tab, and create and expression :
=First(Fields!idEq.Value, "EquipmentDataSet")
but when i execute the query, the promter display <NULL>...
So I don't know how to do and if it is possible !
I hope someone can help me !
Thank you !

Dynamic Dataset For Another Dataset!

Dec 3, 2007

Hi experts,

I'm not sure my design is normal or not. Please give me some advice.

I've a dataset and query by a field name 'companyid'.

select * from companyid where companyid = @icompany which @icompany is a input field.


if user select all, i'll send 0 to @icompany then I need to select all records.

question 1. How can I get all records? (i think about this query select * from companyid <> 0)

if user select for example companyid = 1, i'll send 1 to @icompany and the query work fine.

question 2. How can I change the query to adopt this 2 condition?

Thanks a lot,

Jeff

Back To 6.5

Sep 14, 2000

anyone try to convert a 7.0 database back to 6.5? Is there a way to move the data back or does the 6.5 to 7.0 upgrade change field identifiers or anything else prohibiting the move?

Thanks

Back Up

Sep 19, 2000

Hi all,

We need to restore a back up of database from one machine to another machine. The sql server's are running separately on two of the machines.

We rebuilt the MASTER database on the machine which needs to be restored as there was a conflict in the LOCALE and SORT ORDER.

We rebuilt the Master using the RebuiltM.exe

After that we successfully restored the database. AS BOL suggessted that MSDB and Model had to be restored, thosee two were also done.

But we are not able to see all LOGINS / USERS that were there in the original database.

Are we missing anything that will show up all the users once we restore database from the dump.

Help.
