SQL Query - 'ROUND' COMMAND

May 26, 2007

Has any of you ever had problems with the ROUND command?
I have this operation:
ROUND((FIELD1 / 360 * FIELD5),3) AS FIELD7
(I want the result to be rounded at the third decimal).
SQL makes mistakes in rounding. It seems to me that
the problem relies in the quantity of decimals taken
into account in any single step of the operation.
Thank you in advance.

Is There A Command That Would Stop A Sql Query At A Certain Point?

Jan 22, 2008

I was wondering if there was a command in SQL that you could enter that would stop the execution of a query at a specified spot.

For instance if you were debugging what a batch of update queries were doing to a table and you wanted to stop it at a specific point. I realize you can select the code you want to run, but I would prefer to enter something at a point that stays whether I am selecting it or not. That way when I am looking at a 1000 lines of code I don't have to remember everytime how much to select .

So are there any commands like that? I was thinking something like 'Stop' in VBA but that doesn't work

Using Lock Hints In Query In An OLE DB Command Component

When I try using this sql statement in the 'SqlCommand' property:

UPDATE DIM_Accounts WITH (UPDLOCK)

SET COL1 = ''

SSIS gives a syntax error.

Do you know any workarounds?

SQL Gets Corrupted With 'WITH' Command And Rubbish When Editing Query Containing Derived Table

Jan 31, 2008

When my colleague makes any change to a query containing a derived table, the word 'WITH' followed by a lot of graphical characters appears after the alias, rendering the query unusable. We have tried this with various existing and new, simple queries, all to no avail. We are editing the queries in Visual Studio 2003, and he does not get this effect when using Visual Studio 2005. I can edit the query in 2003 on my laptop with no ill effects.

Help!

I would like to be able to view the complete SQL command that is sent from a Microsoft Access query which has linked SQL Server tables through ODBC, and the query also has some VBA functions manipulating and filtering data.I tried using the SQL Profiler to view the sql command send to SQL Server but all I see is the simple query format and some of the fields. I don't see the fields that have a VBA function such as trim(fieldname) etc in the column. And If I use a VBA fucntion in the Criteria then nothing shows up in SQL Profiled under the TextData column.How can I see the complete SQL command sent to SQL Server?

Error: 8624 Internal Query Processor Error: The Query Processor Could Not Produce A Query Plan.

May 24, 2007

SQL Server 2005 9.0.3161 on Win 2k3 R2



I receive the following error:



"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."



I have traced this to an insert statement that executes as part of a stored procedure.



INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)

VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)



There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.



Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).

SQL Server 2012 :: Adding Count To Query Without Duplicating Original Select Query

Aug 5, 2014

I have the following code.

SELECT _bvSerialMasterFull.SerialNumber, _bvSerialMasterFull.SNStockLink, _bvSerialMasterFull.SNDateLMove, _bvSerialMasterFull.CurrentLoc,
_bvSerialMasterFull.CurrentAccLink, _bvSerialMasterFull.StockCode, _bvSerialMasterFull.CurrentAccount, _bvSerialMasterFull.CurrentLocationDesc,

_bvSerialNumbersFull.SNWarehouseID, _bvSerialNumbersFull.TransAccount, _bvSerialNumbersFull.TransTypeDesc,

[code]...

However, as you can see, the original select query is run twice and joined together.What I was hoping for is this to be done in the original query without the need to duplicate the original query.

Query Fails With Invalid Column Name But Succeed As Sub-query With Unexpected Results

Sep 22, 2015

-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"

set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo

[code]....

This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?

Why The Query Works In Query Analyser And Doesn't Work In Reporting Service ?

Apr 30, 2007



Hello everybody,



I'm developing a report using the following structure :



declare @sql as nvarchar(4000)

declare @where as nvarchar(2000)



set @sql = 'select ....'



If <conditional1>

begin

set @where = 'some where'

end



If <conditional2>

begin

set @where = 'some where'

end



set @sql = @sql + @where



exec(@sql)



I run it in query analyser and works fine, but when I try to run in Reporting Services, Visual studio stops responding and the cpu reaches 100 %.



I realize that when I cut off the if clauses, then it works at Reporting services.

Does anybody know what is happening?

Why the query works in query analyser and doesn't work in Reporting Service ?



Thanks,

SQL Server Admin 2014 :: Estimated Query Plan For A Stored Procedure With Multiple Query Statements

Oct 30, 2015

When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.

1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?

<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>

2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
I executed the code successfully and I got a box which asked for "Enter the query string".
I typed in the following: EXEC dbo.SalesByCategory @Seafood. I got the following box: Query attempt failed. Must declare the scalar variable "@Seafood". I am learning how to enter the string for the "SQL query programed in the subQuery_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnQuery.Click" (see the code statements listed above). Please help and tell me what I missed and what I should put into the query string to get the information of the "Seafood" category out.

Thanks in advance,
Scott Chang

SP To Perform Query Based On Multiple Rows From Another Query's Result Set

Nov 7, 2007

I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w.  one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included)         INSERT INTO @users             SELECT u.userName,u.userID                 FROM  tableU u                LEFT JOIN tableW w ON w.workgroupID = u.workgroupID                WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is:             SELECT u.userName,u.userID
                FROM  tableU u
                LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
                WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!
