How to get the max length of numeric field in a DataSet?
I have a DataSet bound to an Access database. Is it possible to get the maximum length of numeric field of a table in the DataSet? Many fields in the database tables have maximum length values set in ...
Using this IIF statement:
=CountDistinct(IIF(Fields!Released_DT.Value = Fields!Date2.Value, Fields!Name.Value,
Nothing))
Released_DT = a date - 09/03/2015 or 09/02/2015
Date2 = returns another date value in this case 09/03/2015
What I'm trying to do is: count distinct number of people (Fields!Name.Value) if the Relased_DT = Date2.My IIF statement is returning a zero value.
I need to replace Access Val() functions with similiar function in sql.
i.e. Return 123 from the statement: SELECT functionname(123mls)
Return 4.56 from the satement: SELECT functionname(4.56tonnes)
Any one with ideas please
Thanks

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...
thx
Hi!
I create a dataset from a sqlce 3.5 database (I drag-dropped the tables of the database on the DataSet).
And when I try to put a text with more than 4000 characters in the dataset, it throw me an exception ....
--> I tried to insert this text directly in sql ce and it works well! So I think that the DataSet has a limitation?? But the maxlength of the string coloumn of the dataset is set to 536870911
Do you have an idea about this problem?
thx for help and sorry for my bad english

I have a very strange situation. I've increased the size of an NVARCHAR field from 8 to 9 in a database table. The format of the data that I enter will either be an 8 character field (123456-8) or a 9 character field (1234567-9). The '-' is critical.
It used to only accept the 8 character version, but after increasing the field size, if I try to insert the 9 character field version, it gets truncated after the '-', as though it's still only allowing 8 characters. But that only occurs when I include the '-' or other such characters like '#'. If I try to insert 1234567a9, it works. The following explains the outcomes:
Inserted Value -> Result in table
123456-8 -> 123456-8Â Â Â Â Â Â *Correct
1234567-9 -> 1234567-Â Â Â Â Â *Wrong
123456789 -> 123456789Â Â Â *Correct
1234567#9 -> 1234567#Â Â Â Â *Wrong
1234567a9 -> 1234567a9Â Â Â *Correct
Why is it that characters such as '-' and '#' are truncating the value, but only if the string is 9 chars long?
I'm currently using a direct t-sql insert statement in SQLExpress. The field is a simple NVARCHAR(9) field.
I need create a field to store tax rate. I need only 2 decimal points. I defined the field as decimal, precision=5 and scale=2. Does it mean that it can hold value from 0.00 to 999.99?

does anyone know if there is a way, or perhaps a custom toolbox control that is already developed that allows you to drag an entire dataset into a table, instead of pulling everything in field by field...?
was just curious.

is there a property in the sql server where i can track the length of the value in a field.

I have a text field and want to know if any of the text exceeds 10,000 characters
I can do a select max(len(rtrim(convert(varchar(8000)))) on the field but I'm not able to do for more than 8000 and you can't manipulate TEXT datay type.
Any ideas?
Thanks!
I have a database on sql2000. I want to change the length of a field in Table A, but it is related to another field in Table B. When I tried to change the length of the field in Table A via
ALTER TABLE table ALTER COLUMN field varchar(5).The query analyzer generates the following error.
Server: Msg 5074, Level 16, State 8, Line 1
The object 'UQ__table__77BFCB91' is dependent on column 'field'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN field failed because one or more objects access this column.While when I tried the same query on the field in TABLE B, the query completed without any errors.
I'm sure it is possible to select all records where the length of a given field equals a certain value, but I don't know how to do it?
Can somebody tell me how?

Hello, everyone!
What are the precision & the scale values in the numeric field for?(as also in int, etc).I need to have a field that is exactly 6 digits in length. However , when I enter the value , in the length column , it defaults to either 5 or 9 , depending on the precision values. Also when I enter the data , that field accepts not only 9(defined with precision of 10), but more than that, till about 15 digits!!…I think I am not clear on the use of precision…what do I need to define the field as so it accepts only 6 digits? Please enlighten me .
Thanks in advance!

View 1 Replies View RelatedThere are two fieldsA1 nvarchar(30)A2 nvarchar(800)I know nvarchar field is alterable length, if I store a string mystring='abc' to A1 field or to A2 field, I think they use the same disk space, so I think it's always a good way to define a big length nvarchar field such as A3 nvarchar(4000) for any length string, becuase they always use the same disk space, is it right?

Hi,
If I want to make a field of characters to be unlimited length(or maybe 2k for example), what datatype should I use?
Char, varchar and text have a max. limit of 255...
Will appreciate any suggestions.

I have to modify field length in the table, which is part of publication. I tried to use an Enterprise Mgr and received an error message because that table is scheduled for replication.
Is any way around this beside temporary stopping and restarting replication? And actually how to do this to be sure that after restart the data will be again in sync.
We have SQL Server 2000 Enterprise Edition and Windows 2000 Advanced Server.

Hi all,I've set up a page with a gridview, and I'm trying to create a query based on three parameters and to display all records when the page loads.I have created the first two parameters no problem, but I'm having problems with the last one.The parameter is to be populated by a dropdownlist, where the selectedvalue is numeric. I have done a search and found that I can't use the '%' wildcard as it is for a string data type.I have read somewhere that to get around this I can use the CHAR() function to convert to a character, I have tried this without success.When creating the ControlParameter the datatype gets set to string, which I think is not working becuase the input has to be an integer for it to conver to char, am I right?This is the query, and it is the @Application parameter that I'm having this problem with. SELECT dbo.Issue.IssueID, dbo.Issue.ReportedBy, dbo.Issue.ShortDescription, dbo.Issue.DateReported, dbo.Issue.Status, dbo.Priority.Description AS Priority,
dbo.Application.Application
FROM dbo.Issue INNER JOIN
dbo.Priority ON dbo.Issue.Priority = dbo.Priority.PriorityCode INNER JOIN
dbo.Application ON dbo.Issue.Application = dbo.Application.ApplicationID
WHERE (dbo.Issue.Status LIKE '%' + @Status) AND (dbo.Issue.AssignedTo = @AssignedTo) AND (CHAR(dbo.Application.ApplicationID) LIKE '%' + @Application)
ORDER BY dbo.Priority.PriorityCodeHas anyone managed to do this another way?Thanks

View 2 Replies View RelatedI have a numeric data field called Price and this has a value of 0.000 in the db. when i create a package to extract this data to a flat file, the value is displayed as .000
what should i do to make it appear as 0.000 in the flat file.
I tried using a derived column expression where i check if the db value is 0.000 and display it as a string "0.000". this works fine if the OLEDB source is a sql command but fails if the OLEDB source is a sql command from variable.

I have a few columns in table with default value defined as zero length string (''). I want to insert record from DetailsView which uses SqlDataSource as DataSource. In the ItemInserting event, if the data is not valid, I want to use zero length string for the column. But I always get Null instead of zero length string. The code in ItemInserting event looks like this:
If objddl.SelectedIndex > 0 Then e.Values("myFld") = objddl.SelectedItem.ValueElse e.Values("myFld") = ""End If
The line: e.Values("myFld") = "" put Null in the column.
How can I set a column as zero length string using the SqlDataSource?
Any help is appreciated.
Thanks.
Hi,
I have to export data from a database in a special form (the customer wants it this way): every record in one line, and all fields in a large string. Thus, only by convendion it is defined the first seven characters being the central number, the next fivr characters the number of this spare part type, the following 30 the description, and so on...
Just at the end of every record has to be CF-LF.
all works well so far by with this code (in PHP) -
except one thing - see details below the code snippet):
$q1 = "SELECT dirc_matdata.* FROM dirc_vorgang, dirc_matdata ";
$q2 = "WHERE dirc_vorgang.rep_out> '".$anf_dat."'";
$q3 = "AND dirc_vorgang.rep_out < '".$end_dat."'";
$q4 = "AND dirc_matdaten.auftrags_nr = dirc_vorgang.auftrags_nr";
$q5 = "INTO outfile '".$drive.":/matdata.dat'";
$q6 = "FIELDS TERMINATED BY '' LINES TERMINATED BY '
';";
$query = $q1.' '.$q2.' '.$q3.' '.$q4.' '.$q5.' '.$q6;
The INT (integer) fields appear in the (plain text) output file with wrong field lengths. Although I had set the first field (i.e. the number of this type ofparts) to a length of 5, this field appears in the outfile being 10 characters long -- the maximum length of a normal INT type field (and twice as long as it should be).
Or (when set to filed type "MEDIUMINT"), it appears in the length of 8 characters only. But I need this data exactly 5 characters long in this application.
BIG QUESTION: How can I make mySQL (Ver. 4.1) write this fields into the outfile with their correct length as defined in the database structure?
Is this flaw already known in the community?
Is there any sort of "workaround"?
Thank you for every hint!
