On a webpage, there are filters to choose from. Like date, amount, SSN (multiple filters can be choosen).
I have a single query so far.
SqlCommand cmd = new SqlCommand("SELECT [column1], [column2], [column3], [column4], [column5] FROM [table] WHERE [column4] = 'condition4' AND [column5] = @total_bill AND [last_change] >= @txtStartDate AND [last_change] <= @txtEndDate ", Conn) ;
I want to break the query so that it executes on the basis of different sets of conditions (filters). If I dont select date filter, then the above query will not execute properly.
Please help.
I have been working on a pretty ugly stored procedure recently, while debugging I added a char(10) to the end of each line of the SQL query so I could copy it to query analyzer(QA) and debug the SQL syntax output from of the stored procedure.
It had no effect on the stored procedure working, but when I copied the query to QA it got the error below, so I removed them all and added them in one line at a time to find the problem.
--Server: Msg 170, Level 15, State 1, Line 3 --Line 3: Incorrect syntax near ','.
Below are the 2 querys, the only difference is the Char(10) between Amt6 and Amt7!
I’m okay with simple queries but as I’m no expert and have failed to find perhaps the correct wording to describe this method, if at all possible to do, so I have come to ask here.
What I would like to do is take a column from a query and then break down that column into separate results.
So the full query results: 36,18/09/2007 10:00:00,NULL,000102000304,NULL
The column I would like to brake down is (Unique Reference Number): 000102000304
And I would like to break it down to get the last 2 parts (0003 and 04): 0001 | 02 | 0003 | 04
Is this possible to do? If so where should I be looking or what should I be looking at?
Need query to expand the count from a month to the entire year in 2013 .Below is my query where I got the values for a month in 2013 ,How do I expand on this query so that it generates for the entire 2013
Query SELECT RD.RPTDESC,Count(SR.RPTDESC) AS ReportCount,sum(SR.Hrs) as ProdHours,Sum(SR.Mins) as ProdMins, (sum(SR.Hrs)*60+ Sum(SR.Mins)) as TotalProdTime, (sum(SR.Hrs)*60+ Sum(SR.Mins)/Count(SR.RPTDESC)) as AverageProdTime,sum(SR.TriageHrs) as TriageHours,Sum(SR.TriageMins) as TriageMins, (sum(SR.TriageHrs)*60+ Sum(SR.TriageMins)) as TotalTriageTime,(sum(SR.TriageHrs)*60+ Sum(SR.TriageMins)/Count(SR.RPTDESC)) as AverageTriageTime
Also when I am running for months individually there are certain months where for certain reportids there is no data returned,I would like to populate all zeroes for that row for example report id 306 in February and how to get decimal values in average fields.
Hi GuysI don't want to keep asking for your help all the time on each individualquery, so could you please help me to break the myths on the following:1) I have 2 tables. Once is called ACCOUNTS and the other ACCOUNTBUDGET.ACCOUNTS includes all of the usual details for customers and suppliers, egthe account code (as ACCOUNTID), the account name (as NAME), etc.ACCOUNTBUDGET basically holds a transaction line for each month and it'scorresponding year to store the turnover for that month, eg one row containsACCOUNTID, PERIOD (ie the month), YEAR and TURNOVER.Now a lot of the SQL 6.5 tables that I deal with are in this vein and theusual query is that I want to list all of the ACCOUNTIDs and NAMEs thatexist in the ACCOUNTS table and then show for example what their TURNOVER isfor a applicable PERIOD and YEAR, which are all held in the ACCOUNTSBUDGETtable.Now if I do a quick query using MS Query all I get are rows that haverelated values in both the ACCOUNTS and ACCOUNTSBUDGET table when I havespecified say a certain PERIOD and YEAR.The main point of my current reporting problem is that I want to show allthe ACCOUNTIDs and NAMEs in ACCOUNTS that have zero TURNOVER for aparticular PERIOD and YEAR.I'm positive that I have to create a 2 step query/join, but I don't know howto do it. What is the method? People in this NG, can rattle one up inseconds, but I just don't see the logic. Can you help me with this queryand let me know how you manage to fathom it.2) Are there any good web sites that explain in kiddie form how to do thissort of thing?I really appreciate your help on this.RegardsLaphan
I want to write sql query which runs in a background on cyclic basis. Basically i want to count the row entries of 1 table and store the data and the count in two distinct columns.
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?

I have a query with many (approximately, 30) conditions, such as:
select ....... from table1 join table2 on ( (table1.field1 = table2.field1 OR table1.filed1 IS NULL) AND (table1.field2 = table2.field2 OR table1.filed2 IS NULL) )
My question is:
In C++ or C#, when I write a condition like this, say, in an IF or WHILE, I know that I would be better off specifying the IS NULL (well, == null, to be precise) first, and use | instead of ||. In that case, the first condition (equality to null) is checked first, it's fast, and if it's not satisfied, the control flow goes to the next statement.
The question is, is there the same rule in T-SQL?
I mean, if I put the "... IS NULL" first, and then "OR ... = ...", will the query run faster than if I write it the other way around (that is, "... = ... OR ... IS NULL")?
This is very important to me, because most of those fields are VARCHAR, and due to some business rules, I can't change them to numerics etc, which would be compared much faster than text. So, even if I use full text search, I still need to find a way to optimize the query for performance...
By the way, I know that I can put those conditions in the WHERE clause, but as far as I know it won't make much of a difference for performance. So, my question is primarily about the order of conditions, in which SQL Server constructs its query plan.
[Edited:] In other words, what runs faster: comparing varchar to null or comparing varchars? And does it make a difference if I switch their places in my sql script?
We are using SQL Server 2000 SP4, Standard Edition. [Dev edition on the dev machine.]
I've a table with a field named 'TypeOfProd' that has an ID for the various types of products: ex.: 1 - product A 2 - product B 3- product C 4 - product D .... 10 - product J and so on
I need to create a stored procedure that querys only the product types selected by the user.
The user can select 1, 3, 5, 10 or 1, 3 or 3 or 0 for all or some other combination.
For the first user selection a have something like this SELECT Prod FROM tableProd WHERE TypeOfProd = 1 OR TypeOfProd = 3 or TypeOfProd = 5 OR TypeOfProd = 10 For the second, SELECT Prod FROM tableProd WHERE TypeOfProd = 1 OR TypeOfProd = 3
Is it possible to have a stored procedures that runs a query with this random scenario?
I have following query. Now I want to change this in such a way that if Condition 1 satisfies then it should not go to next condition ,if not then should go to next. Similarly the same format till condition 4.
select * from table where IND = 'Y' and ( (STATE = @STATE and LOB =@LOB and COMPANY=@COMPANY)--Condition 1 OR (STATE = @STATE and LOB =@LOB)--Condition 2 OR (STATE = @STATE and COMPANY=@COMPANY)--Condition 3 OR (STATE = @STATE)--Condition 4 )
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
I've got a Table that has over 500,000 row in it. Now I need to convert the whole thing into Excel to import into another application. So I need to break the table into 10 different tables. How can I do that?
I hope I can get this across clearly.I have a table that needs to be broken into 3 tables.Col1 Col2 Col3 Col4 Col5 Col6 Col7Col1 and Col2 need to go into LookupTable1Col3 and Col4 into LookupTable2If Col5 is twice the width.... haha just kidding...so Col5 and Col6 go into LookupTable3There is a 4th table which is made up of foreign keys which are the PK ofLookupTable1,2,3My questions is, how to get the data from the columns of each row and add itto its respective lookuptableand sequentially step throw the table to repeat the above step until I'veprocessed each rowthanks folksT.B
Is it possible by any kind of workaround to break the 8kb limit on user-defines datatypes?
My datatype can contain an arbitrary number of double-precision points meaning that I in best case only can store 512 points (2 x 8 x 512). there's a few extra bytes used for something else, but this is roughly the maximum, which is far from what I in many cases need. I serialize the object myself to ensure that I only store what I really need.
I have a column that has text delimited by a percent sign that I wishto turn into rows.Example:A column contains ROBERT%CAMARDA, I want to turn that into two rows,one row with ROBERT and antoher row with CAMARDA.I will have source rows that have zero, one, or many percent signdelimiters that will correspond to that many rows (One percent signwill create 2 rows, 2 percent signs will create 3 rows and so forth).Any thoughts?TIARob
Hi, I have a report that is frustrating me. I've built this report, and it is not yet used in production. What it does is page break in places that I don't understand.
The FIRST area it would break after a line that had wrapped text to the line below. Even though there was plenty of room to fit it, and the entire rest of the group on the page.
The second area I honestly have NO idea why it breaks.
Does anyone have a routine that takes a row of data from database, duplicates/triplicates it, appends some information to it and writes it out as 2/3 CSV rows.
I want to show a third-level overview of how many to-do items are in various statuses (pending declined and completed) for the third level individuals.
In this example there's 2 regional leaders (level3), each with local leaders (level2) and individual team members (level1)
Status "1" is a new or pending to-do item Status "2" is a declined item Status "3" is a completed item
Here's what I want the output to look like (I may need to add columns for the final report but it should look as follows):
LEVEL3 | Status 1 | Status 1 | Status 2 | Status 3 | LEADER | TOTAL | 2012 | TOTAL | TOTAL | -------|----------|----------|----------|----------| paul | 3 | 1 | 1 | 0 | roger | 1 | 1 | 1 | 0 |
Here's some sample data similar to my live DB:
CREATE TABLE #items (id int, datestamp datetime, userid int, status int) INSERT INTO #items (id,datestamp,userid,status) VALUES (1,'12/26/2011',1,1) INSERT INTO #items (id,datestamp,userid,status) VALUES (2,'12/26/2011',2,1) INSERT INTO #items (id,datestamp,userid,status) VALUES (3,'1/2/2012',4,1) INSERT INTO #items (id,datestamp,userid,status) VALUES (4,'1/3/2012',1,2)
[Code] ....
I have a view called hierarchy that shows me the hierarchy for each level 1 user. Here's the source for the view:
SELECT a.id 'level1', b.id 'level2', c.id 'level3' FROM #users a INNER JOIN #users b ON a.reportsto = b.id INNER JOIN #users c ON b.reportsto = c.id
I've run into table/view limits when using a straight query and timeouts when trying to create a cursor that looks through all level3 users and populates a temporary table with an INSERT and multiple UPDATE statements to get the individual counts for each column for each user.
(Just a note on the actual database in case it's relevant: It has about 1000 LEVEL1 users, 50 Level2, and 15 Level 3 users. It will generate about 1400 to-do items per week.)
I'm having a problem and I cannot seem to find how to fix this anywhere on the web.
I have a stacked bar chart with my data labels showing down the x axis. My client wants me to put a bit of white space between the label and the actual chart. So I tried adding spaces to my data label but of course RS thinks they don't exist since they are not non breaking spaces.
How can I do the following in my chart label
=Fields!Myfield.Value & " "
As you can see I want to add a couple of spaces to my data label. I can't use , all the ampersands get confused. I tried & char(32) but RS doesn't like char(n). I tried ChrW(160) [I saw this in the web somewhere] but this didn't work either.
I'm wondering how most people manage very very large backups. What is the best approach to breaking up the backup files if you're restricted to a drive size (450gig in my case). I unix, you can pipe the backup to gzip and split, I'm not sure how the same thing could be accomplished in windows.
Col 9 is char (2) and Col10 is char (34). It is this column that needs to be broken up into several columns depending on the value in Col 9.
Col1 to Col3 is the key to the record.
So say if record 1 has Col 9 value 'AA' then Col10 ( 34 bytes) is to be spilt into 10+10+10+4 (four columns).The value 'AA' can repeat for several records and the value in Col 10 can change for the same value 'AA'.
Now say record 27 has Col 9 value 'BB' then Col 10 is to be split as 5+25+4 (3 columns).
There are 15 such unique values of Col 9. I have the file layouts for Col 10 for each distinct value of Col 9. So using the file layouts and Table A which exists in my database how do I proceed.
Need I make 15 tables ( one each for the 15 unique Col 9 values). These structure Col1..Col2..Col3...Col9 (the key fields and Col 9) will be common to every table. Plus the file layouts will serve as additional columns specific to each of these tables.
In my database there is a text field type that is used to enter streetaddress. This address could be a few lines long, each line with acarriage return at the end.Is there a way to search for these carriage returns and break out whatis in each line seperately?Thanks.Mike
How do I format a date value in SQL 2000 sp? Tired the following none are returning the quivilent rates. What is the syntax please? SELECT *FROM tblCompanyWHERE ( C_LastBuyDate = '03/21/2008') SELECT *FROM tblCompanyWHERE ( C_LastBuyDate = '2008/03/2008') SELECT *FROM tblCompanyWHERE ( C_LastBuyDate = '03-21-2008')
We run a multiple database environment, with two of the databases receiving most of the user activity. (both write and read). These databases are roughly 25gb each and receive roughly the same amount of activity. Currently both of the .mdf files sit on the same drive shelf. Their log files are located on a separate drive shelf.
Debate: We have an extra fiber channel shelf available for us to use. We are not having too many problems related to performance, but we are always seeking for different ways to increase application/server performance. The debate centers on what to do with the extra shelf. There are two different suggestions on how best to use the shelf. They are:
1)Separate the .mdf files for two most utilized databases. This would separate the databases and the I/O associated with each across two different shelves
2)Break off the indexes for all 5 databases on to the extra shelf. This would leave all the .mdf files on the same shelf, but it would move the I/O associated with the indexes to a different shelf.
Can anyone provide the pros and cons of either suggestion? I would like to see arguements for either side.
We are running SQL Server 2012 on Windows Server 2008. Just wondering what type of actions would break the backup-chain or backup sequence? For instance, if you have tlog backups being taken every 10 minutes and you stop the SQL Server Service for say 30 minutes. Would this action break the backup chain? Or would everything return to normal once the SQL Server Service is restarted?
