Writing A Query To Find Results With Any Spaces Prior To Value
May 13, 2008
I have a table that contains a column called hardness. It is a varchar 50 and actually contains numbers. I did not create the database so not sure why they choose varchar vs. number. I need to write a query that will return all results with a space prior to the number in this column. I am having difficulty and would greatly appreciate some help. Thanks!
I have written several scripts to pull in nested info to the analyzer window. How do I get this data to write to the new table I have created in the database? here is the current script:
select Hierarchy_List.Hierarchy_Label as Hierarchy_Name, Hierarchy_List.hierarchy_ID as Hierarchy_ID, Hierarchy_List.Parent_ID as Parent_ID, frequency_item.manufacturer as Motor_Make, frequency_item.model as Frame from hierarchy_list full outer join Frequency_item ON HIERARCHY_LIST.HIERARCHY_ID = frequency_item.HIERARCHY_ID where parent_id in (select hierarchy_id from hierarchy_list where parent_id in (select hierarchy_id from hierarchy_list where parent_id in (select hierarchy_id from hierarchy_list where parent_id in (select hierarchy_id from hierarchy_list where parent_id=0) and parent_id<>0) and parent_id<>0) and parent_id<>0) and parent_id<>0 and frequency_item.description = 'motor'
I need to move this data to the VAER.Al_Machines and the column names are the same. I can move data via DTS, but it won't work on this because the nested info. Is there a script addendum I can add to this to execute both the search and the transfer in one job so I can automate it? Thanks for any help.
I have a table which has a few fields, one being "datetime_traded". I need to write a query which returns the row which has the closest time (down to second) given a date/time. I'm using MS SQL.
Here's what I have so far:
Code:
select * from TICK_D where datetime_traded = (select min( abs(datediff(second,datetime_traded , Convert(datetime,'2005-05-30:09:31:09')) ) ) from TICK_D)
But I get an error - "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.".
Does anyone know how i could do this? Thanks a lot for any help!
I have a table (represented by #Events) that holds modifications made to another table. I do have some control over the table structure and indexing. I want to pull all of the change records that were made between two dates.
The tricky part is to include the previous version of each record, which will usually be found prior to the start date in question.
The code that I have provided below works. So you can use it to easily see what should be returned. But it's very slow in production.
Any better method to pull this data together?
-- Production version of this table has 4.5 million rows (roughly 1,000 rows per day) -- Primary key is on L4Ident (clustered) -- nonclustered index on ProcessDate, LinkRL4 DROP TABLE dbo.#Events; DROP TABLE dbo.#Results; CREATE TABLE dbo.#Events ( L4Ident int IDENTITY(1,1) NOT NULL,

so i wrote this script and its pretty sweet (tara helped me before on this one) but now, for some STRANGE reason and its been reported by users the following:
the script for example dumps "first name, last name"
when we save the results as a CSV it looks good in notepad...
"first name, last name"
but we kept getting some kind of stange issues when we tried to dump that CSV data into another program to use... so i opened the CSV file in command prompt to see what it really looks like and it is actually "f i r s t n a m e , l a s t n a m e" with all these unnecessary spaces! why is it saving the CSV with spaces in it when my script is nothing of the sort? it was working fine last week, no changes were made to the script but now the CSV's are rendering those weird spaces.
I realize that I need to learn how to write expressions for conditional splits, etc. Frankly, I don't even know what "language" expressions are written in. They look a lot like excel functions to me.
I tried searching the internet for some documentation, but it is sparse.
Can anyone point me to some links, etc that can teach me how to write my own expressions?
I have following query which return me SP/Views and Functions script using:
select DEFINITION FROM .SYS.SQL_MODULESNow, the result looks like Create proc create procedure create proc create view create function
I need its result as:
Alter Procedure Alter Procedure Alter Procedure Alter View Alter Function
I used following
select replace(replace(replace(DEFINITION,'CREATE PROCEDURE','Alter Procedure'), 'create proc','Alter Procedure'),'create view','Alter View') FROM .SYS.SQL_MODULESto but it is checking fixed space like create<space>proc, how can i check if there are two or more spaces in between create view or create proc or create function, it should replace as i want?
hi, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!
Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist. My current SQL statement is as follows. SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))" So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated. Thanks, James.
Iam showing the query results in the asp.net grid. Iam getting a long string with more than 1 space between some words. How i can trim the spaces of that column result.
I tried RTRIM and LTRIM but these functions need two individual strings with spaces either left or right.
SET NOCOUNT ON SELECT table1.column5, table2.column9 FROM table1, table2 WHERE table1.column4 = table2.column4 AND table1.column1 != "NULL" ORDER BY table1.column5
All of the columns are cast as char up to 50 characters.
Even if only a field has a few characters, I get a lot of extra white space in my output. I want to get rid of those trailing spaces. I've tried SET ANSI_PADDING OFF, RTRIM(), and CAST(x AS VARCHAR(y)). I still get the same output. What am I doing wrong, what am I missing?
In SQL Reporting I want the user to pass a parameter to the report; the parameter is a employee number. Easy right, you write a where statement like where table_name.employee_number =@employee_number. When the user runs the report they€™re asked to type in the number.
My problem is the dB stores the employee number with leading spaces padding the number out to 9, so if the user types in 1 they get jack, but if they type in €˜ 1€™ they get the right employee. I can€™t roll it out that way
I€™d do something in the where clause so the user could just type in 1 & it would auto pad out to 9 spaces. I€™ve tried using the €˜LIKE€™ clause & I€™ve tried using concatenate but so far neither works well.
Hello, I have two tables: Customer Training Requests has say two columns.Customer - Class Requested a 1b 1c 1a 2b 2c 3a 3 I have another table called packages, which has packages of class.Package No. Class1 11 2 I want to write a query which will return only those customers who have requested exactly the classes in a particular package.so in above example if the package is 1 the query should return only customer b as only customer b has requested class 1 and 2.

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.
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 ?

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?
Mine Below Query is taking too much execution time. I am using this query in one of my sp. Is there any other way to write this query?

Help! I need to write a query that looks at one table with two columns. One column has 20K records and the second column has 25K records. I need to compare the two columns and pull out the difference between the two columns. The majority of the two columns data is the same but there are some that do not have a match between the two. The data is not in any current order. HELP! THANKS!
Hi, I need some help writing a query, and would rather not go into detail inside here. But if there is someone more advanced in SQL that could help me, could you please write me at g35gurl@yahoo.com. Thanks!
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
is there any better way of writing the below query. i don't want to use select again and again.. and as my table has millions of records.. can u pls.suggest me the best possible method.

I'm assuming it's either a division or some sort of subtractionbut I'm not sure how to formulate the SQL query.Any and all help is appreciated, thanks!
