SQL Server Re-writing Query Syntax

Mar 1, 2008

Hi everyone, is there any way to turn off SQL server re-writing the syntax of certain queries? An example would be if in the where you set primary keys equal to foreign keys and then it converts it to inner-joins. Thanks for your help.

Need Help Writing A SQL Server Query

Mar 16, 2007

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

SQL Server 2014 :: Writing A Cross Join Query With One Table?

Jul 19, 2015

writing a cross join query with one table:

Cities(City_name, X_coordinate, Y_coordinate)

the result should be all combinations without reverse column returns

SELECT * FROM [dbo].[Cities] as P1
Cross JOIN [dbo].[cities] as p2
where (p1.City_name != p2.City_name) and ???

for example if there are three Cities as A,B,C the result should be: A->B, A->C, B->C (without the returns B->A, C->A, C->B)

Server Query Syntax Help

Nov 5, 2006

Hi,

Following is my one of the field of Server table and it s data (SQL Server 2000 Desktop Ver.)

WORK_DESC
G/B SHADE
VALVE R/C
R/C
R/C ISU IND
CP FLANGE R/C
R/C
FAB. KICK LINE
COAT R/C LINE
R/C

To get the specific data of this WORK_DESC from table, I used following query which results fine.

SELECT RpoMstId, RPO_No, Start_Date, WORK_DESC
FROM T_RPO_Master
WHERE (WORK_DESC = N'R/C')

Which results:

R/C
R/C
R/C

What would be the syntax if I need to represent the data that has ‘R/C’ prefix or suffix in the data field? (anywhere in the data column)

With kind regards,
Ashfaque

Need Help Writing A Query

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

Writing A Query

Apr 28, 2006

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

T2_CALENDARIO, -- I just moved this one to the end of the from clause

Need Help Writing A Query...

Apr 15, 2008

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?

Help Writing A Query

Jan 28, 2008

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

Help Writing A Query.

Jul 20, 2005

Hello,I am trying to write a query and getting a little confused.My problem:I send enquiries to partners from 12:00am to 11:59pm each day. 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.

Writing A Query

May 2, 2006

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:

Help Writing Query

Oct 26, 2007

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!

Writing A Query Builder

Apr 29, 2007

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.

Need Help Writing Search Query

Feb 17, 2005

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

Quicker Way Of Writing A LIKE Query

Oct 30, 2007

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...

Writing Alternative Query For Inner Joins

Jun 19, 2007

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??????????

Help Writing A SELECT Query, Please. (Should Be Interesting For You!!!)

May 28, 2008

All- I would greatly appreciate some assistance in creating a SELECT statement for table headcount in the following problem:
First, find the schema here: http://home.pacbell.net/eulimi/schema_headcount.GIF
The problem:
Given a person_id (a record in the person table), list all headcount records WHERE:1) headcount.person_id = person.person_id AND2) the headcount.act_session_id belongs to a activity (from the activity_session table) that the person is allowed to attend by virture of the person's membership in a subexpedition.
Note that:
- A person can be a member of one or more circles (via the circle_person table)- Each circle belongs to exactly one subexpedition.- A persons who is a member of a subexpedition (via one or more circles) is entitled to sign up for one or more activities (activity_sessions) associated with the subexpedition.
So, put yet another way, the SELECT command should show, for a given person_id, the list of records in headcount that includes the activities (act_session_id) that the person is entitled to join by virtue of the persons membership in the subexpedition via his circle. (Whew!)
I hope this is enough information. I think the problem would be fun if I knew what I was doing. (SQL newbie here.) I suspect I need several INNER JOINs and a compound WHERE clause.
Thanks in advance!!!
