There is a column in a table that has values like '23 + 45 + 63', '2 + 54 - 22'... and so on. I want to get the result of this formula as float like 131, 34... and so on. Is that possible with a SELECT statement. I tried:
SELECT CAST('23 + 45 + 63' AS FLOAT)
Didn't work.
Hi,I have three tables in the following structure (simplified):Table 1: Containing the customers-------------------------------------------------create table Customers([cusID] int identity(1, 1) not null,[cusName] varchar(25) not null)Table 2: Containing the customer data fields---------------------------------------------------------------create table Data([datID] int identity(1, 1) not null,[datName] varchar(25) not null,[datFormula] varchar(1500))Table 3: Containing the customer data values-----------------------------------------------------------------create table Values([cusID] int not null,[datID] int not null,[valValue] sql_variant)In this structure the user can add as many data fields to a customer ashe wants (e.g. Country, City, Email, Phone, ...). I have added triggerswhich create a view similar to a pivot (I am working in SQL 2000) andadd triggers to the view so it is insertable, deletable and updateable.What I would like to do, is allow the user to create new fields wherethe values are based upon a calculation. This calculation would be donethrough a formula similar to what he would do e.g. in excel (thisformula is stored in the dimFormula field then).An example might help. Let's assume the user created a field 'Sales'(containing last year's sales) and 'Invoices' (containing the number ofinvoices that were created for him last year). Now, he wants to createa field 'AvgSales' with the formula '[Sales]/[Invoices]'.(Note that through adding these data fields, the above view was created(let's assume it is called vw_Customers and contains the columns [ID],[Name], [Sales], [Invoices], [AvgSales]).What I am looking for is a function which can parse this formula into at_sql query which runs the calculation. So, the formula'[Sales]/[Invoices]' would be translated into (let's assume there areno records with NULL or zero invoices):update vw_Customersset [AvgSales] = [Sales]/[Invoices]from vw_CustomersI am able to do the above with simple calculations (where you can evenuse sql functions e.g. year, len, ...). Now I would like to take thisone step forward into the possibility of using functions with morevariables.For example. Let's assume, the user wants to add a rating (field called'Rating') to his customers based upon the result of 'AvgSales. Heenters the formula 'if([AvgSales] > 2500, 'A', 'B')'.If anyone could help me on this, I would be very grateful. Thanks.M

Hi,
My table has 2 fields as 'count' and 'codes'. The 'codes' field has 'count' # of code values in each record. Size of each code is 4. For example, if my record is 2,'abcdefgh' then there are 2 codes and the values are 'abcd' and 'efgh'.
Currently I am using 'script component' to parse the field into multiple values. Since I have to read 1 million records and on an average, each record has 10 codes, it is taking hrs to load it.
Can it be done without 'script component' using some other transformations?
Thanks.
I'm attempting to use T-SQL to strictly parse/pull Names from a string field like such: CN=John Doe,OU=xyz,DC=ituy,DC=qwer,DC=org...I would like the ultimate result to be JUST the full name John Doe (pretty much everything after the first = sign and before the first comma. I'm attempting combinations of REPLACE, STUFF, PATINDEX and SUBSTRING, but to no avail.
View 5 Replies View RelatedI have a column type of float and How to convert it show like this

Basically, I have a table with a column that stores mathematical formulas in string format. When my UDF is executed, it needs to select an appropriate formula from this table and evaluate it using values that are stored in local variables.
Look at the example below:
Suppose I have a string named @vcFormula that contains the following:"@dVar1 + @dVar2 / @dVar2"Now suppose I have a variable named @dVar1 that contains a value of 1.0, and variable @dVar2 contains a value of 2.5. I can use the REPLACE function to change my original string to look like this:"1.0 + 2.5 / 2.5"
Now I want to execute this string and find the numeric result, placing it in a variable named @dResult. The following works, but presents a problem:CREATE TABLE #Result (dResult decimal(20, 10))INSERT #Result EXEC('SELECT ' + @vcFormula)SELECT @dResult = dResult FROM #ResultThe problem with using this method comes from the fact that I need to be able to evaluate @vcFormula from within a user-defined function, but temporary tables are not allowed inside UDF's.
So I attempted to change the temporary table above into an instance of the TABLE data type. This didn't work either because EXEC cannot be used to populate instances of the TABLE data type. Then I came up with the bright idea to put the code above in a SP and call the SP from the UDF, but of course UDF's are not allowed to call SP's. Specifically, is there any way to execute a command/formula that is contained within a string other than by using EXEC?
Hello all,
I have a question regarding importing text file data into SQL Server. I'm hoping someone can point me in the right direction, as my searches haven't turned up anything specific enough.
I'm trying to parse a large (24MB) text file. It's a fixed-width file, with multiple columns. I need to parse this file, check if a record already exists, and then import the data into the database. But I don't need to insert every column. There's only a few columns from the file I need to insert. This parsing also needs to occur at regular intervals (daily).
I looked at BULK INSERT, but I can't find an example that uses only some of the columns. Every example uses all columns, and the file is delimited, not fixed-width.
Is there anything within SQL Server that can accomplish this? I haven't turned up anything that will solve my problem. The only other solution I can think of is an application that parses the file for me and inserts the data into the database. But can I schedule that application to run every night at midnight (for example) through SQL Server?
I'm not too familiar with SQL Server, so I appreciate any help offered.
Thanks,Jay
Hey Guys I knwo this may sound impossible but lets say I have a number of fields one of which is a Long blob or long text

I have a website, where people upload tab delimited text files of their product inventories, which the site parses and inserts into a database table. Here's the catch: Instead of insisting that each user use a standardized format, each user can upload the file in whatever column order they want, they just have to let the site know through a GUI which column is in which order. And, they may upload columns that if not mapped, will be ignored. Right now, I am doing all of this in code and it runs slow, I was thinking of offloading this to either a stored procedure, ssis, or bulk upload. But, with the varying format of the uploaded text file, I am not sure how I could do that. Any suggestions? Thanks!

I want a function which takes Keyname as input & returns the value related with it if found.
GetValueFmKey('Key1') should return Val1 and like on.
In the following code I want to compare 2 values: AccessVal and SQLVal. The values are stored as nvarchars, so I'm isolating the numeric values in a subquery. Notice I'm only selecting 1 row. The commented line, where I compare the values, is throwing the error.

I've tried converting to numeric, int and bigint instead of float. I've tried CAST instead of CONVERT. Nothing works.
I have a problem at the moment, where the client wants to be able to type in a custom algebraic formula with add/minus operators, and then to have this interpreted, so that the related datasets are then added and returned as a single dataset.
An example would be having a formula stored of [a] + [b] - [c]
and if I were to write the SQL to apply that formula, I might write something like (let's assume 1:1 relationships with the ID's)
select a.a + b.b - c.c as [result]
from z
inner join tblA a on z.id = a.id
inner join tblB b on z.id = b.id
inner join tblC c on z.id = c.id
The formula can change though, maybe things like:
[a] + [b] + [c] + [d]
[a] + [b]
The developer before me wrote something SQL-based where they parsed the string and assigned each value of the formula as either positive or negative (e.g A is positive, B is positive, C is negative, now sum the datasets to get the result), and then created one large table of values then summed them. This does (kind of) work, I'm just contemplating potential alternatives, as it is quite a slow process, and feels like it is quite convoluted, when I get into the details. If I were to do something like this in SQL, I'd normally want each part of the expression to be a column, and then to just apply the operators, but because the formula can change, then the SQL would need to be somehow dynamic for this approach.
In SQL reporting, How do I add the formula in the Formula bar?All the data is coming from a sproc.

I am working on an HTTP POST application where I am using SQL to return "message" based text results.
A typical query would yield a message something like:
135,15,1,1,1,4,1,1,1,"NAME"
I now have a requirement to have the same query return several rows, but when i send them, they need to be a single message containing several records delimited by CRLF, yielding (1) message, so the result set would look like:
135,15,1,1,1,4,1,1,1,"NAME"
135,15,2,1,1,2,2,3,2,"TestName"
135,15,3,1,1,4,1,1,1," 41"
135,15,4,1,1,4,1,1,1,"asd"
how to do this?
I have a column that is populated similar to below
[URL] ....
I need to extract just the 12345 portion. This will always appear after the first "=" and always be proceeded by &UL. I know how I can do this separately, which would be like
To get 12345&UL
ltrim(rtrim(
substring(
replace(cast(MyCol as nvarchar(max)),
'=',
replicate(cast(' ' as nvarchar(max)),10000)),
10001, 10000)))
And then I could run an update on the table after doing the above step using something like
SUBSTRING(MyCol,0, CHARINDEX('&',MyCol))
What I'd like to do is to have everything performed in one step, the above 2 SQL statements combined as one statement, so a separate update does not need to be ran.
Table contains field defined as text. First 12 characters will be date format 'mm/dd/yyyy'. then the next 3 characters could be:
9A, 12P, 3P, 7A or LTL
I would like to convert '9A' to be 09:00AM, so that I can sort by that converted field.
'12P to be 12:00PM and so on....
I have tried various form of case with substring and convert commands, but cant' get the solution. I can not change text field to varchar in table.

We have an interface where we receive data from an external supplier. One of the fields in the interface is of type BLOB (the source is an Oracle database), which would be read into our MSSQL database as image. This can also be converted to varbinary, and a typical field value looks something like:
0x70697A5F8F000000789C0DCCBD0DC2301....etc. etc.
However, we know that the origin only contains text, and we even know the text from the GUI they supply us with. The text could typically be "Delayed by 3 minutes because of water damage" or something like that.
What I want to do, is to extract that text from the field.
First, I have stored the incoming data stream in a table, where one column is of type varbinary(max). It looks like this goes swell. But I don't know which command to use in order to get the text extracted.
I have tried these:
1) select master.dbo.fn_varbintohexstr(Myfield) from Mytable
-> Returns just the text "0x70697A5F8...." which I have no interest in
2) select cast(Myfield as varchar(max)) from Mytable
-> Returns just Chinese signs.
3) select cast(Myfield as nvarchar(max)) from Mytable
-> Returns just Chinese signs.
4) declare @ptrval varbinary(16)
select @ptrval = TEXTPTR(MyField) from MyTable -- with MyField defined as image
READTEXT MyTable.MyField @ptrval 1 30
-> Returns just the text "0x697A5F8...." which I have no interest in
Of course, since only text is stored in this field, the field should never have been defined as BLOB in the first place. But the source system is external, and it's a standard system, so we may not alter it in any way.
I have a flat text file with lots HTML tags and corresponding values

we can easily load a file into db tables. However, my main concern here is the number of columns in the file. A text file TEXT_1400.txt has 1400 columns. I am unable to load data to my db table using BCP or BULK INSERT commands, as maximum of 1024 columns are allowed per table in SQL Server 2008.
We can still go ahead and create ‘Wide Table’ (a special table that holds up to 30,000 columns. The maximum size of a wide table row is 8,019 bytes.). But when operating on wide table, BCP/BULK INSERT commands still fail. After few hours of scratching my head over BCP and BULK INSERT, I observed that while inserting BCP/BULK INSERT commands are unable to identify SPARSE columns and skip these columns, which disturbs column mapping and results in data conversion and trancation errors.
Is there any proper way to load this kind of files into the db table?
