So, what if I wanted to do a search and replace for a single quotation? I can't use that in my search. How to get around that?
example:
Code:
update NamTable
set namstr=replace(namstr,''','')

Hi, I need to write a simple function to format the contents of the fields in my table. I bascially want to say that if the value in a field is below '0' then format the text in colour red and if the value in the field is 0 or above then format it in black. Obviously this can be done by writing an expression in each field but i would prefer to write a function - any ideas.....

Experts: Please assist with coding a trigger for a SQL Server 2005 .NET application.
Here's the scenario:
Suppose there are tables MEMBERS, ACTIVITY, and HEADCOUNT that look like this:
MEMBER
member_id (int)
member_name (varchar(50))
...etc
ACTIVITY
activity_id (int)
activity_name (varchar(50))
...etc
HEADCOUNT
headcount_id (int)
member_id (int)
activity_id (int)
...etc
Suppose also that the ACTIVITY table is already populated with several records, say with activity_id = 1, 2, and 3.
OBJECTIVE: When a new member record is added to MEMBER, say member_id 10, insert one record in the HEADCOUNT table for EACH activity in ACTIVITY for that member. Thus, if member #10 is added to MEMBER, then the trigger (or some other mechanism) would add the following records to HEADCOUNT (which, say, already has 30 records):
headcount_id member_id activity_id
31 10 1
32 10 2
33 10 3
I've been advised that a trigger should do the trick for this, but as I'm totally new to SQL, I'll need some help. I'm guessing some iterating SQL command language might be required, but as I'm new to SQL, I don't know how to proceed.
Note that I'm building an ASP.NET application based on VB, and so records will be added to MEMBER through a tableadapter INSERT command. (Though I suspect this has no bearing on trigger behavior.)
Much obliged for your assistance.

I need assistance on writing a particular query:
I need to be able to filter out duplicates that have different values in a particular field.
For example, I have a table that contains the following:
Code:
WBS1 WBS2 WBS3 Amount Section
123 13 00 475 F
123 13 00 0 L
123 21 01 125 C
123 24 03 50 L
I need to filter out the first two lines because they have the same values for the first three columns but the last column under 'Section' has different values.
Can someone help me?
Thanks

Hello I'm new on sql server and I wonder if there's an specific order for writing a query's clauses (joins, and other conditions in where clause or even the order of the tables in the from clause), I mean, I have a query that takes 1 minute executing, but if I execute the same query after moving the tables in the from clause (changing the order) It takes 5 seconds, could you please tell me Why ??? and what's the best order from writing a query ?
This is the query I was talking about:
SELECT TREP_VALOR_PRECIOS.CDPRECIO,
TREP_VALOR_PRECIOS.NMANO,
TREP_VALOR_PRECIOS.NMSEMANA,

TREP_PRECIOS.CDTIPO_PRECIO,
TREP_VALOR_PRECIOS.SNACTIVO,
'N' SNACTIVAR
FROM
UN_TASASCAMBI, -- I just moved this one to the end of the from clause
T2_CALENDARIO, -- I just moved this one to the end of the from clause
UN_MONEDEXTRA,
TREP_PRECIOS TREP_PRECIOS_BASE,
TREP_VALOR_PRECIOS,
TREP_PRECIOS
WHERE T2_CALENDARIO.CALFECHAINICIAL BETWEEN UN_TASASCAMBI.TASFECHDESD AND UN_TASASCAMBI.TASFECHHAST

Hi Friends,
I need help on writing an optimized query for the following problem..
Consider a table with columns "Date Emp1 Emp2"
Date Emp1 Emp2
1-feb 1 . . 2
2-feb 3 . . 4
3-feb 6 . . 1
4-feb 1 . . 2
5-feb 1 . . 5
6-Feb 5 . . 7
Now, I want search for records with employee id 1 in a way that if column emp1 contains 1 then I want the data in column emp2, and if column emp2 contains 1, then I want data in column emp1.
The output has to be a single column with no duplicate values. In the above example, for employee id 1, the output would be, 2,5 and 6 only.
This table has lakhs of records. I have to scan both columns for a given employee id. What will be the most optimized way to retrieve the data faster. Also, do I need to restructure this table for faster data retrieval?
I have indexes on emp1 and emp2 columns. Do we need union here and if yes, what is the best optimized query for the same?

Hello,
I have a database containing 2 tables:
the first one called "weeks" has 4 columns: id, week number (ex:
2007/01), start date(ex:01/01/2007), end date(ex: 07/01/2007)
the second one is called "tests" and has 5 columns: index, date, name,
test name, duration
my goal: I want to make a query to get rows containing 3 columns:
week number,
name,
dates = date1, date2, etc.,
tests=test1, test2, etc.,
total duration of test for the given week and given person
To be clear, I am trying to get per week a summary of names with the
tests they did and how long total it lasted. The first tables is just
here to get the week number, given the test date.
My current query returns a list of all tests (table 2) with an added
column of the week number and looks like this:
SELECT date, initials, test, [hours outside 8-19], [Week number] FROM
tests, weeks WHERE date BETWEEN [start date] AND [end date]
What I need now is to have one line per person and per week with their total of hours for the week and the list of tests for the same week. I tried lots of things but does not know to get to my goal. Could
someone please help me?
Any help will be appreciated. Thank you in advance

I have tenpartners, and each partner has a different daily limit. In my partner table(Table1), I have a columnm for the Daily Enquiry Limit called "DailyCap". Ialso have a second table (Table2) which counts how many enquiries a partnerhas had and assigns a date stamp.So, my query needs to:Select PARTNERwhere Table2.PartnerCount is less than Table1.DailyCapAND where Table2.TimeStamp between 12:00am TODAY and 11:59pm TODAY.This should hopefully then select any partner who hasent yet reached thedaily cap between midnight start and 24 hours later.Any odeas how to write this query using proper SQL? I have tried butfailed.Regards,Gary.

Hello I'm new on sql server and I wonder if there's an specific order for writing a query's clauses (joins, and other conditions in where clause or even the order of the tables in the from clause), I mean, I have a query that takes 1 minute executing, but if I execute the same query after moving the tables in the from clause (changing the order) It takes 5 seconds, could you please tell me Why ??? and what's the best order from writing a query ?
This is my specific query:
/**************/
This is the first one:
***************/
SELECT TREP_VALOR_PRECIOS.CDPRECIO,
TREP_VALOR_PRECIOS.NMANO,
TREP_VALOR_PRECIOS.NMSEMANA,

I have a database that contains projects and information about the projects.
So, for example:
proj Table
Columns:
project_id
project_name
project_code
Sample Data:
project_id: 1
project_name: Test1
project_code: Alpha6
emp Table
Columns:
employee_id
employee_name
Sample Data:
employee_id: 1
employee_name: david
employee_id:2
employee_name: mike
employee_id:3
employee_name:jason
assign_emp Table
Columns:
project_id = project id from proj table
assign_lab = employee id from emp table
assign_tech = employee id from emp table
assign_tester = employee id from emp table
Sample Data:
project_id: 1
Assign_lab: 1
Assign_tech: 2
Assign_tester: 3
So, I have a table called "proj" that contains the "project_id", "project_name", "project_code" and other various information (not related to my current task). I then have a master employee table called "emp". This contains information about the employees, including the "employee_id" and "employee_name". I then have a 3rd table that links the employee to the project. I've called it: "assign_emp". This table contains the "project_id", "assign_lab", "assign_tech", "assign_tester".
I want to create a query to be able to list the following in a single row, For Example:
Project ID | Project Name | Project Code | Lab Employee | Tech Employee | Tester Employee
1 | Test1 | Alpha6 | david | mike | jason
My problem is figuring out how to select multiple employees from a single table based on whether they are assigned to the project or not. As far as I got was:
Select proj.project_id, proj.project_name, proj.project_code, emp.employee_name as 'Lab Employee' from proj inner join assign_emp on proj.project_id = assign_emp.project_id inner join emp on assign_emp.assign_lab = emp.employee_id where proj.project_id = 1
Any help figuring out the query would be great!

Could someone please help me out? I need to write a sql stored proc to query the following table.My SQL experience is very week. If someone can help me with this, I will be happy to pay you $40 foryour help.
I need the proc to do the following:1.) For every Superintendent in a region, country state and county; return the state name, superintendent name, the county name and and a string which is a comma delimited list of schools they supervise. See the sample output italicised and bold.
So the big challenge here is to also return a string that is a concatenation of school names for a particularSuperintendent in a given state and county. For example: East,Kennedy,Apolo,Morrison.
So basically the stored proc should accept input parameters of the Region, Country, State, and County
Here is the data table:
REGION COUNTRY STATE SUPER_INTENDENT PHONE_NO SCHOOL County
NA USA Texas Mike Andrews 789-3614 East LakeNA USA Texas Mike Andrews 789-3614 Kennedy LakeNA USA Texas Mike Andrews 789-3614 Apolo LakeNA USA Texas Mike Andrews 789-3614 Morrison LakeNA USA Texas Amy Markson 789-2134 Anderson MaylorNA USA Texas Amy Markson 789-2134 Molina MaylorNA USA Texas Amy Markson 789-2134 Polima MaylorNA USA Ohio Terry Ellis 966-8314 Kingston KeelNA USA Ohio Terry Ellis 966-8314 Martin KeelNA USA Ohio Terry Ellis 966-8314 Eastmore KeelNA USA Ohio Terry Ellis 966-8314 Canondale Keel
Here is the sample output the way it will appear on a web form:
State:Texas County:Lake
Mike Andrews East,Kennedy,Apolo,Morrison 789-3614
County:Maylor
Amy Markson789-2134 Anderson,Molina,Polima
State:Ohio County:Keel
Terry Ellis Kingston,Martin,Eastomore,Keel

Hi All,
For one of our projects, we are supposed to write a query builder to display reports in tabular format. For the filter criteria ( i.e where clause ) user can select from a list of predefined columns and assign conditions to it. For example, user can select 'CustomerName' as the column and specify condition where name begines with 'A'. Similarly he can also select ouput columns
Problem
The columns that user selects can come from different tables. We are planning to store mapping between tables and columns and also their primary and foreign keys in an xml file. But I would want to understand how to build the join clause.
For example, say there are 4 tables customer, customer address, order, and items. Say user wants the number of items purchased by each customer who stays in 'Delhi'.
1. In output column he selects customer.name and count(items.id)
2. In filter criteria he selects address.city = 'delhi'
How would the query builder know that to join customer and items, order also has to be joined. Any pointers would be helpful.

I am not very familiar with the syntax of MS SQL and I am trying to write a stored procedure which would do a search and return matching records.
This is what I need to achieve:
for instance I create a form with 4 text fields
- First Name
- Last Name
- Employee ID
- Date
I am interested in writing a stored procedure that would run a select query based on the input in the text fields
e.g.
- if the user enters First Name and the Last Name (leaving Employee ID and Date fields blank) query should be something like
select * from Employee where FirstName like @FirstName and LastName like @LastName
- or if the user enters only the Employee ID stored procedure should run a query similar to
select * from Employee where EmployeeID like @EmployeeID

Hi
I have two product tables in two different databases, both contain thousands of records. I have to write a query that suggests matches on similar codes, and have come up with:
SELECT TB1.product, TB2.product
FROM TB1
JOIN (select distinct product
from db2.dbo.TB2) as TB2 --this table has PK of product and warehouse
ON TB2.product LIKE '%' + TB1.product+'%'
which DOES work, but because the table have many rows,takes time to do it... is there a way of rewritting this query, so it gives a faster result?
Thanks in advance...

I am using a Table Many Times in Left Outer Joins and Inner Joins for various Conditions,
is there anyway of writing a query using minimal Table usage, instead of Recurring all the time.
**********************************
SELECT
blog.blogid,
BM.TITLE,
U.USER_FIRSTNAME+ ' ' + U.USER_LASTNAME AS AUTHORNAME,
Blog_Entries = (cASE WHEN Blog_Entries is NULL or Blog_Entries = ' ' then 0 else Blog_Entries END),
Blog_NewEntries = (cASE WHEN Blog_NewEntries is NULL or Blog_NewEntries = ' ' then 0 else Blog_NewEntries END),
Blog_comments = (cASE WHEN Blog_comments is NULL or Blog_comments = ' ' then 0 else Blog_comments END),
dbo.DateFloor(VCOM.objCreationDate) AS CreationDate,
dbo.DateFloor(BLE.entryDate) AS Date_LastEntry
FROM vportal4VSEARCHCOMM.dbo.blog_metaData BM
INNER JOIN vportal4VSEARCHCOMM.dbo.blog BLOG
ON BM.BLOGID = BLOG.BLOGID
INNER JOIN vportal4VSEARCH.dbo.[USER] U
ON U.USER_ID = BLOG.OWNERID
INNER JOIN vportal4VSEARCHCOMM.dbo.vComm_obj VCOM
ON BLOG.vCommObjID = VCOM.vCommObjId

ON BLOG.BLOGID = BLE.BLOGID
LEFT OUTER JOIN
(SELECT BlogID, Blog_Entries = COUNT(*)

LEFT OUTER JOIN
(
SELECT BlogID, Blog_NewEntries = COUNT(*)

Hello....
i have 4 tables in a databse(tab1,tab2,tab3,tab4). id is the attribute of TAB1 and id also foreign key of all the tables.....That mean id attribute exists on all the tables........so when i want to query to more than 1 table , i have to go for Joins...basically i am using innerjoin.........
Can u tell me is there any other way to find the same output as the innerjoin......without using the keyword INNER JOIN
for example ......SELECT * FROM TAB1 INNER JOIN (TAB2 INNERJOIN TAB3 ON TAB2.ID=TAB3.ID) ON TAB1.ID=TAB2.ID
another query........
SELECT *FROM TAB1,TAB2,TAB3 WHERE (TAB1.ID=TAB2.ID) AND (TAB2.ID=TAB3.ID) AND (TAB3.ID=TAB1.ID)
above queries are same or not??????????
