Record Groups In Blocks Via A Query

Jun 11, 2007

I'm trying to place records into groups of 100, so I need a query that will return records but not based upon an autonumber type field. For instance, if I had a set of records that had been sequentially numbered (by autonumber) with IDs to greater than 3,600 but there were actually only 300 IDs remaining ranging from 1 to 3600 (say the others were deleted), then I would want to use a query to make three groups of 100 of the remaining IDs.

I can use SELECT TOP 100 for the first 100 records. How do I get subsequent groups of 100?

It's probably obvious and I am thinking too hard.

Generate Single Record That Shows Status Of Accounting Period For Multiple Groups?

Mar 26, 2015

I'm trying to generate a single record that shows the status of an accounting period for multiple groups. For a single accounting period they could all be the same, or all be different (open, closed, hold, etc)

What I want to do is select the accounting period with a group by that says if all the groups are in the same status, then that's the status. But if there are different status' for the period, I just want to have a single line that says 'Mixed' The query below returns 3 records, but I only want 2. I tried a CASE WHEN Having COUNT > 1 but it blew up with an aggregate subquery in a group by error.

DECLARE @AccountingPeriod Table
(AccountingPeriod varchar(10), Status char(1), GroupNum int)
Insert into @AccountingPeriod
Values('2015-03','O',1),
('2015-03','O',2),
('2015-03','O',3),
('2015-02','O',1),
('2015-02','O',2),
('2015-02','C',3)
Select AccountingPeriod, Status from @AccountingPeriod
GROUP BY AccountingPeriod, Status

Query Timeouts When Updating A Record Retrieved Through A Websphere JDBC Datasource - Possible Record Locking Problem

Apr 7, 2008

Hi,

We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.

If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.

Thanks,
Sarah

The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.

This is running on a Websphere Application Server v6.1.

Code snippet - getting the record thru JDBC:


DataSource wsDataSource = serviceLocator.getDataSource("jdbc/dsSQLServer");
Connection wsCon = wsDataSource.getConnection();


// wsCon.setAutoCommit(false); //have tried with and without this flag - same results

Statements stmt = wsCon.createStatement();


String sql = "SELECT * FROM Person where personID = 12345";
ResultSet rs = stmt.executeQuery(sql);


if(rs.next()){
System.out.println(rs.getString("lastName"));
}

if (rs != null){
rs.close();
}
if (stmt != null) {

stmt.close();
}
if (wsCon != null) {

wsCon.close();
}

Problem With Matrix (in Subreport, Multiple Groups), Groups Repeating First Row Data

Jan 25, 2008

I have a new SQL 2005 (SP2) Reporting Services server to which I've just upgraded and deployed some SSRS 2000 reports.

I have a subreport that contains a matrix with two groups. The report data seems to be inexplicably repeating the data for the first row in the group for all rows in the group. Example:









ID1
ID2
DisplayData

1
1
A

1
2
B

1
3
C

2
1
A

2
2
B

2
3
C

Parent group is on ID1, child group is on ID2, report would show:








1
1
A

2
A

3
A

2
1
A

2
A

3
A


Is this a matrix bug in 2005 SP2, or do I need to do something differently? I can no longer pull a comparison version from an SSRS 2000 server to verify, but I believe it was working as expected before...

Logging Blocks

Apr 23, 2008

I would like to log blocks to see what causes it.

One hack of a way to do it is to run code similar to that which populates the blk column in sp_who; on a job every 5 seconds. It would store the results of code similar to the sp_who output whenever any of the rows has a value greater than zero in the blk column.

This way, I can see what was going on at the time there was a problem.
Does anyone have a better strategy for this?

Using Try Catch Blocks In Stored Procedure

Tempdb Is Locked And Blocks Other Users

Oct 18, 1999

When I am running reports on SQL Server 6.5 database which involves creation of temp tables, whole tempdb is locked. All other users are blocked,

The reports involve queries which fetch data into temporary tables, as,

SELECT c1 , c2, c3 ...
INTO #tmp1
FROM T1
WHERE C1 = xxx
AND .........

When any of these queries are run, it blocks all other operations using TEMPDB, like creation of temporary tables or queries using sorts etc.

It appears that the query locks the system tables (sysobjects, syscolumns) in TEMPDB.

However, the above query works fine if it is constructed as,

CREATE TABLE #tmp1 (a1 ..., a2 ...., a3 ..... )

INSERT INTO #tmp1
SELECT (c1, c2, c3)
FROM T1
WHERE c1 = xxx
AND .........

Could someone please tell me what actually is happening in the first scenario. Is there a way avoid the blocking of TEMPDB usage other than the workaround mentioned above (which means I have to change all my queries) ?

Thanks

Best Method For Moving Blocks Of Records From One Db To Another?

Feb 6, 2008

I wanted to set up a mechanism that would transfer blocks of records (a few dozen to in rare cases a few thousand), with slight modification, from one database to another. It's a sort of custom partial archiving process that would be triggered from a web-based admin application. Records in the target db would be identical except:

-- the primary key in the source table, an identity field, would be just an integer in the target table
-- the target table has an extra field, an integer batch ID supplied by the web application that triggers the process

It's a simple, if not efficient matter to do it within the web application: query the source table, suck the records into memory, and insert them one by one into the target db. This will be an infrequent process which can be done at off-hours, so a bit of inefficiency is not the end of the world. But I wondered if there is a more sensible, orthodox approach:

-- Could this process be done, and done efficiently, as a stored procedure with the batch ID passed as a parameter?
-- Is there any way to do a bulk insert from a recordset or array in memory using ADO and SQL? And if so, is that better than inserting records one by one?

Advice on the best general approach would be appreciated, and I will try to figure out the details.

SSIS Package BLOCKS At Opening.

Mar 21, 2006

Hallo,

I'am relatively new to SSIS-programming and experiencing a serious problem with a package (6618 KB large) containing 5 dataflows. These dataflows all start from a datareader-origin and flow trough multiple transformations. While editing the fifth dataflow the developmentenvironment suddenly became unworkably slow. After any modification made to the dataflow it takes several minutes before I can continue editing. Meanwhile in the task manager the process devenv takes a very large portion (50 to 100%) of CPU.

Building the package,shutting down SSIS and even rebooting the PC don't make any difference. When you close the package ands reopen it, this takes at least 10 minutes.

We work with Microsoft SQL Server Integration Services Designer
Version 9.00.1399.00.

Does anyone know if there is a limit to the number of transformations in a flow or the size of a package? Could that be the problem?

Before this problem occured I was multiplying transformations by copying ,renaming and altering them within a dataflow. Could SSIS have some problem with that?

Any suggestion for solving this problem, other than chucking it all away an restarting, will be gratefully accepted.



With kind regards,





Paul Baudouin

Reusable Blocks Of Code In Stored Procedures

Apr 15, 2008

I have several stored procedures with a similar query. The SELECT clauses are identical, but the FROM and WHERE clauses are different.

Since the SELECT clause is long and complicated (and often changes), I want to place the SELECT clause in a separate file and then have the stored procedures include the block of text for the SELECT clause when they compile.

Is this possible? Looking through the docs and searching online, I don't see any way to do this.

Delete Statement Times Out And Blocks Reads

Aug 21, 2007

Hi. Periodically I need to run a delete statement that deletes old data. The problem is that this can timeout using ODBC (via the CDatabase and CRecordSet classes in legacy code). Also, while its running the delete, the table its operating on is locked and my application can't continue to run and operate on rows not affected by the delete.

Are there any workarounds for this? Can the timeout be set in the connect string?

Thanks,
Brian

Data Application Blocks For Windows Mobile

Feb 5, 2006

I've read that microsoft.applicationblocks.data for .net v2 can't be deployed to a mobile app, and my experience bears that out. So I 'm wondering if there are application blocks for windows mobile 5 that would know how to both talk to sql server mobile and sql server 2005. I see OpenNetCF has a port but as far as I can tell, they only address sql server mobile and not talking to a sql server 2005 remote database. I can use the OpenNetCF version for my sql server mobile requirements, but I'm hoping there is an encapsulation of sqlclient calls for communication with my server db.

thanks

Best Method To Move Blocks Of Records From One Database To Another

Feb 7, 2008

I wanted to set up a mechanism that would transfer blocks of records (a few dozen to in rare cases a few thousand), with slight modification, from one database to another. It's a sort of custom partial archiving process that would be triggered from a web-based admin application in plain old ASP (not .net alas). Records in the target db would be identical except:

-- the primary key in the source table, an identity field, would be just an integer in the target table
-- the target table has an extra field, an integer batch ID supplied by the web application that triggers the process

It's a simple, if not efficient matter to do it within the web application: query the source table, suck the records into memory, and insert them one by one into the target db.

-- Is there any way to do a bulk insert from a recordset or array in memory using plain ASP, ADO and SQL? And if so, is that better than inserting records one by one?

I realize that the ASP.NET tableadapter and dataset features might provide a good solution, but in the short run I can't rewrite the whole application. Advice on the best general approach from an ASP-ADO platform would be appreciated, and I will try to figure out the details.
