Jul 18, 2015Using TSQL, I have a table that holds filenames of Pictures for products. Different products can be using the same picture. I need to select the filenames for a single product only if it does not exists for a different product.I have tried Where Exists (select FileName From Tbl where
Prod_Id = @var) AND NOT EXISTS(select FileName From Tbl where
Prod_Id != @var) In the Select Statement.
Return The Results Of A Select Query In A Column Of Another Select Query.
Feb 8, 2008Not sure if this is possible, but maybe. I have a table that contains a bunch of logs.
I'm doing something like SELECT * FROM LOGS. The primary key in this table is LogID.
I have another table that contains error messages. Each LogID could have multiple error messages associated with it. To get the error messages.
When I perform my first select query listed above, I would like one of the columns to be populated with ALL the error messages for that particular LogID (SELECT * FROM ERRORS WHERE LogID = MyLogID).
Any thoughts as to how I could accomplish such a daring feat?
Select Query Based Upon Results Of Another Select Query??
Sep 6, 2006Hi, not exactly too sure if this can be done but I have a need to run a query which will return a list of values from 1 column. Then I need to iterate this list to produce the resultset for return.
This is implemented as a stored procedure
declare @OwnerIdent varchar(7)
set @OwnerIdent='A12345B'
SELECT table1.val1 FROM table1 INNER JOIN table2
ON table1. Ident = table2.Ident
WHERE table2.Ident = @OwnerIdent
'Now for each result of the above I need to run the below query
SELECT Clients.Name , Clients.Address1 ,
Clients.BPhone, Clients.email
FROM Clients INNER JOIN Growers ON Clients.ClientKey = Growers.ClientKey
WHERE Growers.PIN = @newpin)
'@newpin being the result from first query
Any help appreciated
A Query To Find Primary Key
Sep 4, 2007I have a query that can tell me the columns in a table. In this case "Contact". What I would like to add to my query is if the column is part of the primary key. Can that be done? how so?
Code Snippet
SELECT
c.name AS column_name,
c.column_id,
SCHEMA_NAME(t.schema_id) AS type_schema,
t.name AS type_name,
t.is_user_defined,
t.is_assembly_type,
c.max_length,
c.precision,
c.scale
FROM
sys.columns AS c
JOIN sys.types AS t ON
c.user_type_id=t.user_type_id
WHERE c.object_id = OBJECT_ID('Contact') ORDER BY c.column_id;

Problems With Insert Query And Primary Key
Nov 27, 2007I am trying to run an insert query off of a sql datasource and I am erroring out. My code and stored procedure as of now are listed below. You will notice the section of the stored procedure that is pulling the value for facility_ID (primary key). I have also tried to pull these and pass the parameter from a label, but that does not work, giving an error that the stored procedure expects the parameter @Facility_ID which was not supplied. One other odd thing is that stepping through the code, I watched the parameter count total 21, but when running the insert command, the insert parameter count shows 20. With the code below (my current project), I get an error that null values can not be entered for facility_ID. Please help.

View 11 Replies View RelatedSlow Query On Primary Key Using LEFT
Dec 19, 2001My table consists of about 1.4 Million Records. The PK is a CHAR field and ranges in size from 3 - 25 characters. I need to pull a recordset using the LEFT function.
Example: SELECT blah WHERE LEFT(myPK, 8) = 'AIRBILLNU'
This query takes about 115927ms to run and the server is 100% CPU bound, it should only bring up 2 records. Seems like the index is not being used. I know the DB design is probably not the greatest, we probably should have had an INT PK and IX on the other field which is now the PK. I cannot do anything about that at this point.
Is there anything I can do to speed up this query.?
Thanks,Adrian

Result Sets Using Select In Query Anlyzer Vs BCP Vs Select Into
Jul 9, 2002When I run simple select against my view in Query Analyzer, I get result set in one sort order. The sort order differs, when I BCP the same view. Using third technique i.e. Select Into, I have observed the sort order is again different in the resulting table. My question is what is the difference in mechanisim of query analyzer, bcp, and select into.

Create A Query That Will Give Result Set Containing Primary Order On Type
May 14, 2012I have a table with plant types and plant names. Certain plants are grouped on a custom field, currently called Field. I am trying to create a query that will give me a result set containing the primary order on Type, but need items with the same 'Field' value grouped by each other.For example, the following shows a standard query result with "order by Type", ie select * from plants order by Type
Code:
ID Type Name Field
1 Type1Name1(group1)
2 Type2Name2(group2) -group2
3 Type3Name3(group3)
4 Type4Name4(group4)
5 Type5Name5(group2) -group2
6 Type6Name6(group6)
But I want it to look like this, with fields of the same value located next to each other in the result set (but still initially ordered by Type)
Code:
1 Type1Name1(group1)
2 Type2Name2(group2) -group2
5 Type5Name5(group2) -group2
3 Type3Name3(group3)
4 Type4Name4(group4)
6 Type6Name6(group6)

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

_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.

Transact SQL :: Use Query Results As Select Criteria For Another Query
Jul 10, 2015I have a query that performs a comparison between 2 different databases and returns the results of the comparison. It returns 2 columns. The 1st column is the value of the object being compared, and the 2nd column is a number representing any discrepancies.What I would like to do is use the results from this 1st query in the where clause of another separate query so that this 2nd query will only run for any primary values from the 1st query where a secondary value in the 1st query is not equal to zero.I was thinking of using an "IN" function in the 2nd query to pull data from the 1st column in the 1st query where the 2nd column in the 1st query != 0, but I'm having trouble ironing out the correct syntax, and conceptualizing this optimally.
While I would prefer to only return values from the 1st query where the comparison value != 0 in order to have a concise list to work with, I am having difficulty in that the comparison value is a mathematical calculation of 2 different tables in 2 different databases, and so far I've been forced to include it in the select criteria because the where clause does not accept it.Also, I am not a DBA by trade. I am a system administrator writing SQL code for reporting data from an application I support.
Transact SQL :: SELECT On Column Name From Query Result Set In Same Query?
May 9, 2015I have a column colC in a table myTable that has a value (e.g. '0X'). The position of a non-zero character in column colC refers to the ordinal position of another column in the table myTable (in the aforementioned example, colB).
To get a column name (i.e., colA or colB) from table myTable, I can join ("ON cte.pos = cn.ORDINAL_POSITION") to INFORMATION_SCHEMA.COLUMNS for that table catalog, schema and name. But I want to show the value of what is in that column (e.g., 'ABC'), not just the name. Hoping for:
COLUMN_NAME Value
----------- -----
colB 123
colA XYZ
I've tried dynamic SQL to no success, probably not executing the concept correctly...
Below is what I have:
CREATE TABLE myTable (colA VARCHAR(3), colB VARCHAR(3), colC VARCHAR(3))
INSERT INTO myTable (colA, colB, colC) VALUES ('ABC', '123', '0X')
INSERT INTO myTable (colA, colB, colC) VALUES ('XYZ', '789', 'X0')
;WITH cte AS
(
SELECT CAST(PATINDEX('%[^0]%', colC) AS SMALLINT) pos, STUFF(colC, 1, PATINDEX('%[^0]%', colC), '') colC

Declaring A Table Variable Within A Select Table Joined To Other Select Tables In Query
Oct 15, 2007Hello,
I hope someone can answer this, I'm not even sure where to start looking for documentation on this. The SQL query I'm referencing is included at the bottom of this post.
I have a query with 3 select statements joined together like tables. It works great, except for the fact that I need to declare a variable and make it a table within two of those 3. The example is below. You'll see that I have three select statements made into tables A, B, and C, and that table A has a variable @years, which is a table.
This works when I just run table A by itself, but when I execute the entire query, I get an error about the "declare" keyword, and then some other errors near the word "as" and the ")" character. These are some of those errors that I find pretty meaningless that just mean I've really thrown something off.
So, am I not allowed to declare a variable within these SELECT tables that I'm creating and joining?
Thanks in advance,
Andy

(
declare @years table (years int);

Select Query Vs Store Procedure Query
Oct 29, 1998hi, does it make a difference to write the following select statement in either query window or create a sp and then calling the store procedure to be executed..
select * from authors
OR
create procedure authors as
select * from authors
lets assume that we have million records in the author table. is it faster to run the query from within a store procedure or not ?
thanks for your input

Query Based Off Primary Key Of Parent Table - Adding Child Table
Jan 28, 2012I need to add a child table that will tell us who the participants counselor is, what I did was I did a Make Table query based off the primary key of the Parent table and made that the link (foreign key) for the People_tbl and the Counselor_tbl, so if the counselor changes then the user adds the record to the counselor tbl and then puts in the Effective date. The problem is that when I run a report it doesn't show the present counselor always shows the old counselor?
Code:
SELECT Student_ind.StudentFirstName, Student_ind.StudentLastName, Student_ind.[Student ID], People_tbl.[Family ID], People_tbl.FirstName,

Student_ind ON People_tbl.[Family ID] = Student_ind.[Family ID]

Auto Incremented Integer Primary Keys Vs Varchar Primary Keys
Aug 13, 2007Hi,
I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.
For example:
id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]
isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.
Regards
Mike
SQL Server 2008 :: Change Primary Key Non-clustered To Primary Key Clustered
Feb 4, 2015We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?

Nov 21, 2006Hi,
I have been having problems trying to sort this query out and would appreciate some pointers.
I have a SQL Server table 'Match' which includes the columns:
match_date datetime
age_group int
The match_date column includes both date and time values. The age_group column is an id linked to an 'Age_Group' table.
I would like the select query to retrieve the top 3 dates (not including times) and the agegroups for these dates.
For example:
The table data might include
match_date, agegroup
--------------------
10/11/2006 10:00, 1
10/11/2006 11:00, 1
10/11/2006 12:00, 1
10/11/2006 13:00, 2
03/11/2006 09:00, 3
03/11/2006 10:00, 4
03/11/2006 11:00, 5
25/10/2006 10:00, 2
20/09/2006 10:00, 5
20/09/2006 10:00, 6
I would like the SELECT to retrieve like so:
match_date, agegroup
--------------------
10/11/2006, 1
10/11/2006, 2
03/11/2006, 3
03/11/2006, 4
03/11/2006, 5
25/10/2006, 2
So the query only returns the one record for each age_group on each date for the top 3 dates.
Does anyone have any ideas? I hope I have explained it well enough!
Thanks,
Pete
Select Query
Feb 27, 2007Hi, I'm trying to do the following select statement.
I have the following databases with the following tables and columns which will be involved with the query.
DataBase Name: usersTable: UsersColumn: UserNameColumn: UserId
DataBase Name: documentareasTable: document_areaColumn: doc_area_idColumn: doc_area_nameColumn: doc_area_typeColumn: doc_area_defaultTable: document_area_user_accessColumn: doc_area (contains a doc_area_id)Column: user_id (contains a username)
Now I want to select the doc_area_name where the logged in username exists in the user_id of the document_area_user_access table.
So to clarify, I am looking to look through the document_area_user_access for each time the current users username exists and for each existing username the doc_area_name is displayed depending on what doc_area(s) is associated with the user_id in document_area_user_access.
Don't know if this has made any sense??
I am hoping to do all this in the aspx sqlsource if possible. As for each userarea that the user has access a link will exist.
Cheers, Mark
SELECT Query
Apr 3, 2007Hello,I have the following tables:[Blogs] > BlogId (PK), ...[Posts] > PostId (PK), BlogId (FK), Title, Content, ...[Labels] > LabelId (PK), LabelName[LabelsInPosts] > LabelId (PK), PostId(PK)I am selecting all posts from a Blog given the BlogId:SELECT * FROM dbo.Posts WHERE BlogId = @BlogIdThis will return the columns Title, Content, ... for those posts.I would like to add 2 columns, PostLabels and LabelsCount:1. PostLabels would be created by:For each post select all the labels associated with it inLabelsInPosts. Then for each label get the label name. Then createthe value of PostLabels which would be each label separated by acomma.I tried the following but this is not working. I am having problems getting the LabelId from LabelsInPosts and then getting the LabelName from Labels and use them to create the CSV string:SELECT DISTINCT l1.PostID, STUFF((SELECT DISTINCT TOP 100 PERCENT ',' + l2.LabelName FROM Labels AS l2 WHERE l2.PostID = l1.PostID ORDER BY ',' + l2.LabelName FOR XML PATH('')), 1, 1, '') AS PostLabelsFROM Labels AS l1ORDER BY l1.PostID2. LabelsCount would be the number of labels associated with each postI created a procedure which, given a PostId, returns the number oflabels associated with it.So I suppose it would be only a question of integrating a call tothis procedure with this SELECT I am trying to create.Thank You,Miguel
