Transact SQL :: Select Seems To Be Ignoring WHERE Conditions

Apr 23, 2015

SQL Version:  2008 (not r2)
Problem:  My Select statement seems to be unaffected by some of the conditions in the WHERE Clause.  For instance

JCCD.Mth >= cutoffs.FiscalYear_FirstMonth (value '20130101') AND JCCD.Mth <= @WIPMonthCurrent (value '20130101')AND LTRIM(RTRIM(JCCD.Job)) = '71-' (see output and code below)
SQL Code:
declare @WIPMonthCurrent date  = '20130101'
SELECT  
     JCCD.JCCo, JCCD.Job, JCCD.Mth, JCCD.Source, sum(JCCD.ActualCost) AS CostToDate

[code]....

SqlDataSource Select Is Ignoring My Filter

Sep 25, 2007

I am using the SqlDataSource to access the dB from my page. Basically this is what I do with it ds.SelectParameters.Clear();
ds.SelectParameters("Id", TypeCode.Int32, id.ToString());

DataSourceSelectArguments dssa = new DataSourceSelectArguments();
dssa.MaximumRows = 1;
dssa.AddSupportedCapabilities(DataSourceCapabilities.Page);

DataView dv = (DataView)ds.Select(dssa);
if (dv.Count > 0)
{
// collect the information
string title = (string)dv[index].Row.ItemArray[0];
}
And the SelectCommand attribute of the SqlDataSource is set in design mode to "SELECT * from vw_Items ORDER BY Category".
So, since I am trying to retrieve just the item with the given Id I was expecting just one record but when I step through I see that the data view has a count of 9 (all records in the table) !!!
What am I doing wrong here? why can't it return just one? as per the select statement which after adding the parameter should be something like "SELECT * FROM vw_Items WHERE ID = 5 ORDER BY Category

Transact SQL :: CASE - Maximum Number Of WHEN / THEN Conditions

Oct 20, 2015

I need to update many rows in some table.  I've made such SQL query:

UPDATE [%TableName%]

Select Max Value From Prior Where Conditions

Apr 7, 2006

I can't figure this out for the life of me. Wanted to know if it's possible to select certain date conditions in a query, then later reference those conditions and to only select the max of them.

I need to do this dynamically as I do not know what the max value is. I've provided an example below:

Select var1
From table1
where
(
(Date1 = '11/30/2005')
OR
(Date1 = '12/31/2005')
)
and Date1 = (Max of previously selected values e.g. '12/31/2005')

What I can't figure out is how to dynamically retrieve the max of 11/31/2005 and 12/31/2005. Any ideas are greatly appreciated.

1. Select A Field Twice With Different (special) Conditions

Sep 12, 2007

Hi guys,

My challenge is really 3 problems in 1.

I have Table1 and Table2 which are inner joined with an ID.
Each record in Table1 may have up to two corresponding values in Table2, which are Type and Name.

req1- I want to select Table2.Name twice (or more), with each selection conditioned on a specific Type.
req2- I also want all information pertaining to the same ID to be returned in each row
req3- I want all IDs to be returned, even if Table2.Name are empty for Type1 and/or Type2.

So, the source tables look something like this:

Table1.ID | ……
-----------------------
ID001
ID002
ID003
ID004

Table2.ID | Table2.Type | Table2.Name
--------------------------------------------------------
ID001 | Type1 | NameA
ID001 | Type2 | NameB
ID002 | Type1 | NameC
ID003 | Type2 | NameD


Ideally, my results should look like this:

Table1.ID | Table2.Name (Type=1) | Table2.Name (Type=2)
----------------------------------------------------------
ID1 | NameA for Type1 | NameB for Type2
ID2 | NameC for Type1 | (empty)
ID3 | (empty) | NameD for Type2
ID4 | (empty) | (empty)

Right now, I can only get Table2.Name to display once, and it won’t return the empty values, even with outer joins. The structure that I’m using is:

SELECT …
FROM …
WHERE Table2.Name IN
(SELECT Table2.Name
FROM Table1 INNER JOIN Table2 …
WHERE Table2.Name = ‘Type1’)

Sorry the abstractness, but this is the simplest way for me to express the problem.

Any help will be appreciated, thanks!

T-SQL (SS2K8) :: Select Query With Multiple Where Conditions And OR Operator

Feb 6, 2015

I have the got below T SQL query to fetch the matching record

DECLARE @MappingTable TABLE
(
Productname nvarchar(10),
identification_key1 int,
identification_key2 int,
identification_key3 int

[Code] .....

-- result - 'Orange'

This is an exact matching record and straight forward

Is it possible to identify the record using T SQL query based on the following scenarios

1) return the record - If all the three where conditions match
2) if record not found check and return the record where 2 columns values in the where condition match

-- Expected Result for below query: 'Orange', because 2 of the columns in where condition have matching values

SELECT Productname
FROM @MappingTable where identification_key1=1 or identification_key2 =2 or identification_key3 =1

-- result - 'Orange'

SQL Server 2008 :: Join Another Table But With Select Conditions?

Mar 24, 2015

I have this sql....

Select
DISTINCT p.dbPatID, p.dbpatfirstname, p.dbPatLastName,
s.dbSchTypeCnt as SchDetailType, t.dbSchTypeCnt as SchTypeType,
ISNULL(r.dbStatusDesc, 'No Ref') AS dbStatusDesc,
ISNULL(t.dbSchTypeCode, 'No Ref') AS dbSchTypeCode,
ISNULL(t.dbSchTypeDesc, 'No Ref') AS dbSchTypeDesc,

[code]....

however, I only want the lastest a.dbPatApptTime and only when a.dbPFStatus = 1 and a.ClientRef = 'EPS'

So the stand alone sql could be....

Select Top(1) dbPatApptTime as LastVisitDate, dbSchTypeDesc as LastVisitDesc
from appointments
where dbPFStatus = 1 and clientref = 'EPS'
order by dbPatApptTime desc

I'm just not sure how to incorporate that into my sql or whether there is a better way,

Select Rows Based On Multiple Date Conditions

Jun 5, 2008

Hi,
I have 1 table with 5 rows. One of the rows has dateTime values. I want to know how many rows there are with a value in that column < today AND how many rows there are with a value in that column > today.
I'm not sure how to do this.

SELECT Count(*) WHERE dateColumn <= today AND dateColumn > today gives me everything.
I like to end up with a column containing the count of rows <= today
and a column with rows where date > today.

Is this possible in SQL or do I have to retrieve all rows and then loop over the resultset and check each row?

Thanks,
Marc

JOIN Efficiency Using Multiple ON Conditions Versus WHERE Conditions

Jan 10, 2008

My question is fairly simple. When I join between two tables, I always use the ON syntax. For example:


SELECT

*
FROM

Users

JOIN UserRoles

ON (Users.UserRoleId = UserRoles.UserRoleId)


No problems there. However, if I then decide to further filter the selection based on some trait of the UserRole, I have two options: I can add the condition as a WHERE statement, or I can add the condition within the ON block.

--Version 1:

SELECT

*
FROM

Users

JOIN UserRoles

ON (Users.UserRoleId = UserRoles.UserRoleId)
WHERE

UserRoles.Active = 'TRUE'


-- Version 2

SELECT

*
FROM

Users

JOIN UserRoles

ON (Users.UserRoleId = UserRoles.UserRoleId

AND UserRoles.Active = 'TRUE')


So, the question is, which is faster/better, if either? The Query Analyzer shows the two queries have the exact same execution plan, which makes sense, since they're both joining the same tables. However, I'm wondering if adding the condition in the ON statement results in fewer rows the JOIN statement initially needs to join up, thus reducing the overall initial size of the results table before the WHERE conditions are applied.

So is there a difference, performance wise? I imagine that if Users had a thousand records, and UserRoles had 10 records, then the JOIN would create a cartesian product of the two tables, resulting in 10,000 records in the table before the WHERE conditions are applied. However, if only three of the UserRoles is set to Active, would that mean that the resulting table, before applying WHERE conditions, would only contain 3000 records?

Thanks for whatever information you can provide.

Transact SQL :: Select From A Select Using Row Number With Left Join

Aug 20, 2015

The select command below will output one patient’s information in 1 row:

Patient id
Last name
First name
Address 1
OP Coverage Plan 1
OP Policy # 1
OP Coverage Plan 2

[code]...

This works great if there is at least one OP coverage.   There are 3 tables in which to get information which are the patient table, the coverage table, and the coverage history table.   The coverage table links to the patient table via pat_id and it tells me the patient's coverage plan and in which priority to bill.  The coverage history table links to the patient and coverage table via patient id and coverage plan and it gives me the effective date.  

select src.pat_id, lname, fname, addr1,
max(case when rn = 1 then src.coverage_plan_ end) as OP_Coverage1,
max(case when rn = 1 then src.policy_id end) as OP_Policy1,

Ignoring A Column In During DTS

Nov 1, 2004

I'm importing from an Excel spreadsheet into an SQL Table using DTS.

Two things:

1. I don't want anything imported into Column 1 of the table as this has been designed to automatically increment (creating a primary key). I haven't worked out how to do this.

2. How can I get the DTS package to ignore the top 2 rows of the Excel spreadsheet (header information)?

An answer to one will be great but both will be tremendous!!

Query Ignoring Filter?

Feb 29, 2008

All,

So I have this query that is ignoring my date filter and for the life of me I can't figure out why. Was hoping some guru could explain it to me. Here goes:

This query ignores my date filter:

SELECT
rcv.Name AS MachineName,
r.JobId,
j.Name AS JobName,
r.CreateTime AS JCreateTime,
rsv.Name AS JResultStatus,
rpv.Path + rpv.Name AS ResourcePool,
rcvv.ResourceConfigurationVal AS Dimension

FROM
dbo.Result_View AS r
INNER JOIN dbo.ResourceConfiguration_View AS rcv ON r.ResourceConfigurationId = rcv.Id
INNER JOIN dbo.Job_View AS j ON r.JobId = j.Id
INNER JOIN dbo.ResultStatus_View AS rsv ON r.ResultStatusId = rsv.Id
INNER JOIN dbo.Resource_View AS rv ON rcv.ResourceId = rv.Id
INNER JOIN dbo.ResourcePool_View AS rpv ON rv.ResourcePoolId = rpv.Id
RIGHT JOIN dbo.ResourceConfigurationValue_View AS rcvv ON rv.LatestResourceConfigurationId = rcvv.ResourceConfigurationId
LEFT JOIN dbo.Dimension_View AS d ON rcvv.DimensionId = d.Id

WHERE
(r.CreateTime > DATEADD(DAY, -15, GETDATE()))
AND
(rcv.Name LIKE 'PNP%')
AND
(d.Id = 859)
OR
(d.Id = 860)

If I comment out the last two joins and associated select/filters, all of the sudden the date filter works again. From everything I have read, the joins are supposed to be processed BEFORE the filters are applied in the virtual table. My DB goes back a number of years and contains millions of records. W/O the date filter, the query takes a very, very long time to run.

Any ideas on why this would happen?

Thanks,

Allen

Views Ignoring Order By Clause

Sep 7, 2007

I have just transferred my site to a new server with SBS R2 Premium, so the site's database changed from SQL 2000 to SQL 2005.   I find that searches are now returning results in random order, even though they use a view with an Order By clause to force the order I want.
I find that the results are unordered when I test the view with Management Studio, so the issue is unrelated to my VB/ASP Net code.
Using my SQL update tool (SQL Compare, from Redgate) I find that there are no differences in the views, or the underlying tables.
Using Management Studio to test a number of views, I find that I have a general problem with all views.  For example, one of the simpler views is simply a selection of fields from one table, with an Order By clause on the tables primary key: -       SELECT     TOP (100) PERCENT GDQid, GDQUser, GDQGED, GDQOption, gdqTotalLines, GDQTotalIndi, GDQRestart, GDQCheckpointMessage,                             GDQStarted, GDQFinished, gdqCheckpointRecordCountr       FROM         dbo.GEDQueue       ORDER BY GDQid DESC
If I right-click the view (from Management Studio's Object Explorer pane), select Design from the menu to show the view's design, and then click the Execute SQL icon, the view's results are displayed perfectly, in descending order of GDQid.  However, if I select "Open View" the view's results are displayed out of order.
When I do this with the SQL 2000 database, both Design/Execute and Open View correctly display the data in the correct order.
Is there something that I should check in the SQL 2005 installation - some option that has been set incorrectly?
Regards, Robert Barnes

Ignoring A Parameter Value In A Stored Procedure

Jun 2, 2006

If you have a table called Person and has ID, Age, Gender and Name. And you have a stored procedure:
CREATE PROCEDURE [dbo].[GetName]@Age TINYINT,@Gender TINYINTASBEGIN    SELECT Name FROM Person   WHERE Age = @Age AND Gender = @Gender END
You want some times to send @Age as null to get all ages (or in other words, you are not concerned with the age) or @Gender as null to get all genders.
A way to do that is to build your query string dynamically and execute it with EXEC command. However, this is a bad solution because you are losing most of the SP benefits and writting longer and more complicated procedures, specially that you have a lot of parameters!
Another solution that I thought of is having your select like this:    SELECT Name FROM Person   WHERE Age = ISNULL(@Age,Age) AND Gender = ISNULL(@Gender, Gender)
However, I noticed that when the value of the column is NULL, you will get false results, obviously because you are using = operator in comparing a value with null while you should be using IS operator, so this method did not work.
I am wondering if any one has a good solution for this.

Search By Ignoring Special Characters

Dec 14, 2011

In our schools we have a number of East-European, Turkish, Scandinavian, ... students. Their names contain "special" characters, like Ö, Ü, Ø, ... Our users want to be able to search for student names without having to enter those special characters. Most often they don't know the exact spelling of the names and they get "no match found" messages as a result.

They want to have persons with the name Ösgür, Osgueld, ... in the result set after entering "osgu" in the search field.

What is the best way to do this? I was thinking about using another collation near the LIKE, but I don't know if that would work and how it should be done. The Database collation is Latin1_General_CI_AS.

Order By Ignoring The Hyphen Character

Sep 24, 2007

Hi,
I'm using the following SQL script to return a list of part number and the order is not what I expect. Perhaps this is a collation problem but I have no idea where to look to modify that.

Thanks in advance, John
select part from transactions T where (T.transdate between '20070701' and '20070705') and
(T.transtype = 'ISSU' or T.transtype = 'RTRN') order by part


Here is the beginning of the Transactions table create script


CREATE TABLE [Transactions] (
[RecNo] [int] IDENTITY (1,1) NOT NULL,
[Part] [nvarchar] (30) NOT NULL ,
[TransDate] [nvarchar] (8) NOT NULL ,
[TransType] [nvarchar] (4) NOT NULL ,
[FromLoc] [nvarchar] (10) ,


The 'Part' column is an alphanumeric field. The problem I am having is that the
Order By seems to ignore the hyphen character '-' when the returned rows
are ordered by the Part (which can contain hyphens in any column).

Here is an example of what I get.

130909N9
130909N9
130909N9
1-480698-0 * These two should not be here
1-480699-0 *
15-423
164-07700
164-07700
164-07700
1683


I was expecting this ( and I get this in and older database ).

068-03000
068-03000
06A19956
074-03200
077-367-0

Files Ignoring Permission Inheritence

Feb 29, 2008

Hi,

This may be a silly question out of ignorance, but I'm working in an environment where I am a DBA for a server, but I'm not a local admin on the windows server for the first time, so sorry if it is

Anyway, I have set up some traces that are writing to a file stored in a directory I have full control on. However, the trace files themselves are not inheriting the folder permissions, even though the folder is configured to do so. The only logins with access are the Local System account, the SQL Server service account local group, and the local administrators group.

Is this something that SQL Server does on its own, or would this have to be something the system admins have set up with group policy or something? If its SQL Server, is there some configuration setting I can change to get it to stop doing that so I can stop bugging the admins to give me access every time I run a trace?

Thanks,

Larry

Delete From A Table Ignoring A Foreign Key

Dec 6, 2007

Hi,

I am looking to delete a single row from a relatively small table. Unfortunately, there is a foreign key relationship between this table and a much much larger table. The checking of this foreign key when I am deleting this row seems to significantly impact the performance of the operation. Previously there was an index on this larger table that helped this query run. This index has been dropped to improve the performance of a more frequently executed operation.

Is there a way I can use a hint or something to stop SQL checking this foreign key when deleting the row? I am certain that there are no associated rows in the larger table.

I have read elsewhere that I could disable the foreign key, perform the delete, then enable the foreign key. This delete statement is not a one off process and could happen in the normal operation of the application so I don't really know what the implications of doing this are.

Any suggestions would be appreciated.

Thanks

Rich

SQL Query Ignoring Null Values In Joins-- Help

Aug 2, 2006

I would like to populate a grid with data from 2 different tables.
Table1: [PK]id(int), name(nvarchar), areaID(int)
Table2: [PK][FK]areaID(int), areaDescription(nvarchar)

My cerrent query is:
SELECT Table1.id, Table1.name, Table2.areaDescription FROM Table1 INNER JOIN Table2 ON Table1.areaID = Table2.areaID

However, sometimes the areaID in Table1 will only be populated at a later stage and therefore will be NULL in Table1. Table2 is used as a lookup table when inserting into Table1. This query therefore ommits any records in Table1 which do not have an areaID. I would like to view ALL records(ones without an areaID as well) as they would be populated in the grid and selected to be updated on web forms because they are incomplete and then subsequently assigned an areaID.

Any help with this query would be much appreciated...
