Character To Numeric Conversion Error- Select Statment On Char Column
Sep 18, 2007
Hi guys/ladies I'm still having some trouble formatting a select statement correctly.
I am using a sqldatasource control on an aspx page. It is connecting via odbc string to an Informix database.
Here is my select statement cut down to the most basic elements.
SELECT comment
FROM informix.ipr_stucom
WHERE (comment > 70)
The column "comment" contains student grades ranging from 0-100 and the letters I, EE, P, F, etc. Therefore the column is of a char type. This is a problem because I cannot run the above statement without hitting an alpha record and getting the following error
"Character to numeric conversion error"
How can I write this statement where it will work in the datasource control and have it only look at numeric values and skip the alpha values?
I have tried case with cast and isnumeric... I don't think that I have the formating correct.
I have also used:
WHERE (NOT (comment = ' I' OR comment = ' EE' OR comment = ' NG' OR comment = ' WP' OR comment = ' WF' OR comment = ' P' OR comment = ' F'))
This works but is very clunky and could possibly break if other letters are input in the future. There has to be a better way.
I am sorry for my ignorance and thanks again for your help.
Hi, I have a little bit of a problem I cannot seem to figure it out. Is it possible to write a Select statement that contains a WHERE column_name > desired_numeric_value The tricky part it that the column is of CHAR type and can contain numeric grades ranging from 0-100 or the letter I for Incomplete. My SQL was working perfect when this column contained only numbers as soon as a record with I was added I get the following error: Character to numeric conversion error This report will be used to find students who have failing grades. Thanks for any help!

I'm trying to select only July from show_held but I keep on getting the error message saying:
Conversion failed when converting date and/or time from character string.
I get error message after I write this code:
ANDshow.show_held = '&July&'
As you can see from the below code, How do I select July from times_held_in_July?
SELECTevent_name, DATENAME (MONTH, show_held) AS times_held_in_July FROMevent, show WHEREevent.show_id = show.show_id
Result:
event_name times_held_in_July DressageJuly Jumping July Led in July Led in September Led in May DressageApril DressageJuly Flag and PoleJuly SELECTevent_name, DATENAME (MONTH, show_held) AS times_held_in_July FROMevent, show WHEREevent.show_id = show.show_id ANDshow.show_held = '&July&'
Result:

gives the error mentioned above. Each select statement, when run separately, works fine. Any clues?
Hi,I'm new at asp .net and am having a problem. On a linkbutton click event, I want to insert into my db a row of data which includes two parameters. Param1 is the id of the logged in user, and Param2 is <%#DataBinder.Eval(Container.DataItem, 'UserId')%> which is the username of a user given through a datalist.When I execute the query: "insert into aspnet_friendship (userId, buddyId) values (@Param1, @Param2)"I get the error: Conversion failed when converting from a character string to uniqueidentifier.I am trying to insert these into my table aspnet_friendship into the columns userId and buddyId which are both uniqueidentifier fields. I tested the query using the same values (@Param1, @Param1) and (@Param2, @Param2) and found out that the problem is with Param2 because when I use Param1 the insert works perfectly. The value passed by Param2 is supposed to be the id of a user which I get from the datalist which selects * from aspnet_Users, so that <%#DataBinder.Eval(Container.DataItem, 'UserId')%> should also be an Id like Param1 is. Since both params are in the form of .toString(), I don't understand why one works but the other doesn't.As you can see in the code below, both of these parameters are dimmed as strings, so I don't understand why Param2 doesn't work. Can anyone please help?

I've imported a CSV file into a table in SQL Server 2012. It's a large file, 140,000+ rows, so I couldn't covert it to Excel first to preserve the date format due to Excel's row limit. In the CSV file, there were 3 column with date data in "31-Aug-09" format, and the import automatically transformed these in "31AUG09" format (varchar(50)) in SQL Server. Now I need to convert these 3 columns from varchar to datetime so I could work with them in date format.
i am working on a small project, that I have found that someone is storing a float as a varchar(). But there are also some actual words in the same column.
I am trying to determine how I can select only the rows with alphabetical characters in that column.
I want to be able to select the rows with only the alphabetical characters. There is a huge mix, and I am assuming that every first letter is one of the 26 alphabetical character used. How can I write a query to use a REGEX to select any and all rows that cannot be CAST as a Float? I have nill to no experience using REGEX.
I'm designing a database that will not be that large (I would be surprised if it ever surpassed 50,000 rows across all tables), but will be accessed quite often, so I am doing my best to optimize its structure, such as doing 3NF, selecting appropriate data types, etc.
I have a few columns that will contain numeric data (such as an invoice number (from an external source) or location ID). However, one of my classes in college was about database design, and we were taught that if you won't be doing mathmatic computation on a field (such as the invoice or location fields I mentioned earlier), then you should use a string literal type (char, varchar, etc.)
Unfortunatly, the professor did not explain much as to why this should be done. From the standpoint of semantic analysis, these types of fields are probably more labels than they are numbers. However, I don't find that very convincing (or even helpful).
In short, my question is that given a column holding numeric data that isn't worked on in a mathematical sense, is it really better to mark it as a string literal than a number? Any articles or studies I can read relating to this?
I would think that comparisons would be faster with int, as well as data storage (though, as mentioned, that's not as big of a concern). Sadly, Google doesn't have many helpful resources. (Lots of stuff on char vs varchar, though.)
I read the topic from JROdden and this case is similiar but...
I got several varchar fields with values like 1.2 1.3 ... these I can covert with select CONVERT(dec(5,2), fieldname) as fieldname
In fact I also solved undefined- and NULL-values with. CONVERT(decimal(12, 2), CASE WHEN GESCHKOSTMAX IS NULL OR GESCHKOSTMAX < '0' THEN '0' ELSE GESCHKOSTMAX END) as GESCHKOSTMAX,
But now there are values like 1,4 and these ones neither CONVERT nor CAST will handle.
I tried the SELECT DISTINCT KMPAUSCHALE FROM extr_INTFIRMA WHERE (isnumeric(KMPAUSCHALE) = 1)
and get 0,40 0.25 0.30 and so on...
The error is: [Microsoft][ODBC SQL Driver][SQL Server]Error converting datatype varchar to decimal. (or float or numeric (whatever I tried))
I think the easiest way would be to insist on higher data quality but I also would like to solve this interesting challenge.
Thanks for any hints
By the way, I followed rudys link to http://rudy.ca/afdb.html and now I know how I could protect myself !!!!
There must be a voice in my head saying: Try the db-forum, try it and stay happy... ;-)
I have to store the result of a calculation in a column of type CHAR(7) (and am unable to change the column type).
The calculation can have results ranging in size from 0.1234567 to 99999999.
In the first case, I would need to store the value of 0.12345 in the column. In the later case, an error should be thrown.
So I need to store all of the significant digits from the left of the decimal (if there are < 7) and as many of the digits to the right as will fit into a CHAR(7), with the remaining precision being truncated.
I have imported some data to sql2k from my old system. Somehow, it importedinvoice amount to char type.I just created another column called invamt2 type NUMERIC so I can copy orconvert content of invamt which is type CHAR. There are about 50,000records.How can I convert/cast from char type to numeric type ?Thanks
Hello, I am from the school of thought that you should in every case have your primary keys as numeric values only. However, where I currently work there is a project leader who is a recent FoxPro convert (I know, they are tough ones to crack). I made the suggestion recently that the keys in the table should be numeric and with him being the project leader and me just a lowely developer he said get lost. I made the point that later joining your tables together in a PK/FK relationship where the keys where character would be slower then with numeric keys. He didn't listen and now we are approaching production with a database that is really just a bunch of text file. He said that with SQL 7 it doesn't matter if the pk is numeric or character. I disagree. But I need solid documentation to take to him and to the managers to convince them. If anyone out there could advise me on this. And if anyone could give me or tell me where I could find documentation on why even in SQL 7 there is a need to use numeric keys that would be a great help and you would be making one more shop in this world a little bit more technically sound :-) Thank you in advance for your help.
HiI have a character field (char ot varchar) that I want to force only tocontain numeric characters.Can that be done by way of defining a constraint on the field ?or by any other way in the field/table definition ?What id the syntax ?Anyone have examples ?ThanksDavid Greenberg
hello all,is there a quick way to convert a zipcode of type int, to a 5 characterchar value ?e.g.declare @zip intdeclare @czip char(5)select @zip = 2109select @czip = convert(char, @zip)select @czipbut with @czip = 02109 instead of 2109 ?thanks in advance
I'm wondering which way is the best way to store your numeric values. It probably doesnt matter, b/c you can always convert back and forth...but i'm just wondering what the best practice is i guess...
I'm scrambling to complete a project and ran into an int to char problem. I'm sure, in my haste, I'm doing something stupid. Here is an example of what I'm trying to do but it doesn't convert as expected. I want the SEQ_NBR2 value to convert from 4 to 0000004.
select right('0000000' + convert(char(7), isnull(a.SEQ_NBR2, 0.0)), 7) fromTXN_HEAD_837 a where a.file_auth_nbr = '1084472388468' anda.seq_nbr2 = 4 and a.sgmt_id2 = 'BHT'
I have data tables that include ZIP code, as char(5). The values looklike integers, but they are padded with leading zeroes to fill out 5characters, '00234'.There are SPs to look up data, with @Zip char(5) among the parameters.Some users call these with integer values, @Zip = 234, and SQL makesthe conversion. Is it necesary to add the leading zeroes in the SP --@Zip=RIGHT('00000'+@Zip,5) -- or would SQL find this match? (234 ='00234'). It looks like the conversion is to '234' and the matchfails.Thanks,Jim GeissmanCountrywide
In SQL I need to be able to take a varchar parameter @Area and convert it to a float.
The input values for @Area I can't control. They can range from 6300 to 6,300 SqFt to 1.2 Acres .
So to convert this value to a float I basically look through the string and remove everything that isn't a number or a period. Then I would convert this value to square feet based on how large the number is.
select @k = patindex('%[^0-9. ]%', @Temp) while @k> 0 begin select @Temp = replace(@Temp, substring(@Temp, @k, 1), '') select @k= patindex('%[^0-9. ]%', @Temp) end
If @Temp = '' BEGIN SET @Temp = '0' END
SELECT @SqFt = Convert(Float, @Temp)
--Distinguish if it was acres or square feet If (@SqFt > 750.00) BEGIN SET @SqFt = @SqFt END ELSE BEGIN SET @SqFt = (@SqFt * Convert(Float,43560) ) END
SELECT @SqFt
This works great except for one situation, If @Area is something like 6,300 Sq.Ft. . When I run it through the part that removes all non-numeric items and periods, I end up with 6300 .. . So to get around this I want to find the first letter in the string and then remove everything after it. Then take the result and run it through part that removes everything but the numbers and period.
However I can't find away to get the index of the alpha-numeric character and remove everything after it.
Hi All there - I want to show the o/p of a cursor on a single line. There is a numeric variable that needs to be clubed with the character variable. If I use char() the o/p is not right. How do I do that?
Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error.

I am trying to convert a single code page MS Server database into a unicode database, using the unicode data types,NCHAR, NVARCHAR, NTEXT. The problem is that in the original database, indexes and constraints have been defined on the tables whose configurations need to be changed. As a result, the ALTER TABLE command fails. Are there any other alternative solutions? Also, data from the old database needs to be preserved. The objective is to create a unicode database which keeps the old data intact as well as accepts the new data in unicode. It would be great if you could help! Thanks, Sheetal.
