SELECT column_name, data_Type, character_maximum_length
FROM information_Schema.columns
WHERE table_name='***'
ORDER BY ordinal_position
but I have problem to get the actual maximum length of the each column. Anybody have the similar query?

Length Of Varchar In SQL7.0
May 2, 2000Hi,
I am trying to insert text into a varchar(5000) column from a JAVA program. I am using MSDE database (which I believe is a strip down version of SQL7.0), with a variation of ms SQL Server 3.70.06.90 ODBC driver and tds jdbc driver from inet software. With the ODBC driver, I don't get any error but the data saved is only 255 characters. With the latter driver, I get a data truncation error and nothing is saved.
Any help is appreciated.
Thanks

Aug 21, 2007
Hi all,
a simple question to ask for varchar type. I want to update a varchar type parameter to a stored procedure to update a table. My question is , if I don't specify the length. and the varchar type will be trimmed to only 1 character. I thought it's supposed to be 50 by default? Besides if I need to compare varchar values, do I need to specify length as well? Cheers.

Varchar Minimum Length Check
Oct 7, 2007Hi,
I have a column set to varchar(12) so I can ensure that the length of the string entered will never be more than 12 characters but I want to limit the string to a minimum of 8 characters, so I end up with a string that is from 8-12 characters long. How do I ensure the minimum length of 8 characters? I'm using SQL Server 2005 if that helps. I tried adding a check constraint like so:
DATALENGTH(UserName) >= 8
But I keep getting an error when I save the table, so any help would be very much appreciated.
Thanks
Varchar Absolute Max Length Of 1024 Characters. Why?
Oct 1, 2000Hi all,
I have a strange situation. I have a field in the database that has to be a string type field of around 4000 characters.
So naturally I setup the field as
type: varchar
length: 4000
However when I try to put any text in this field I find that I can put no more than 1023 characters of ascii text in there.
To check if this was a max record length prob I setup a test table with only 2 fields:
ID: int, PK, Identity
longVarchar: varchar, 4000
and tried to put some ascii text into the field called longVarchar. Again the most I could put in was 1023 characters!
Thinking that it could just be that SQL svr box that was wacky, I tried it on another one with the same result.
I have tried using other field types (nvarchar, char) and have found that they all could only hold 1023 characters max, no matter what how high I defined the size of the field.
Try it out yourselves and see if you get the same result. Any useful suggestions would really be appreciated.

Dynamically Changing The Length Of A Varchar(n) Field
Dec 26, 2006Hi Everyone,I have a question about dynamically changing the length of a varchar(n)field, in case the value I'm trying to insert is too big and will givea "truncated" error, but before the error is given! i.e. Is there somekind of a way to "test" the length of the field while Inserting thevalue into it, and to have it automatically increase its length to thelength of the value being inserted, in case the value is too big?I've been able to do this in a "primitive" way, simply by identifyingthe specific error number in case the value is being truncated, andthen increasing the length of the varchar(n) field by using the ALTERcommand, and then duplicating the insert statement, but is there astandard (shorter) way of doing this?Here is my code (I'm working in an ASP environment):<%var_txt = "abcdefghijklmnopqrstuvwxyz12345678789"sql = "Insert Into Table1 (text) Values ('" & var_txt & "')"On Error Resume Nextconn.Execute sqlIf err = -2147217833 ThenResponse.Write "Error Recognized Successfully!<br /><br />"sql = "ALTER TABLE Table1 ALTER COLUMN text VARCHAR(" &Len(var_txt) &") NOT NULL"On Error Resume Nextconn.Execute sqlIf err<>0 ThenResponse.Write "Error while trying to alter Column:<br/>" & err & "= " & err.description & "<br />"ElseResponse.Write "Column altered successfully to: " &Len(var_txt) &"<br />"sql = "Insert Into Table1 (text) Values ('" & var_txt &"')"On Error Resume Nextconn.Execute sqlIf err<>0 ThenResponse.Write "<br />Error number 2:<br />" &err.description &"<br />"ElseResponse.Write "Now it was added successfully!HaHa!<br />"End IfEnd IfElseResponse.Write "Success."End If%>Thanks in advance!

Aug 9, 2007
Hi all,
I'm trying to get an understanding of a serious problem I have with a large DB in production. This is going to be obvious to someone (everyone probably) <bg>
I have a table which consists of numerous varchars and ints but also a Text type field. This table resides in a SQL 2000 Database. This DB currently has a data file size of 16Gb and a Transaction Log size of 17Gb. When I edit the table and increase the size of a Varchar field from 50 to 100 these files grow to more than double their size!
Why is this happening and how can I prevent this?
TIA

Advice Needed : Nasty Problem PHP/MS SQL Server And Varchar Fields &> 255 In Length
Jul 20, 2005I am currently working on a PHP based website that needs to be able to drawfrom Oracle, MS SQL Server, MySQL and given time and demand other RDBMS. Itook a lot of time and care creating a flexible and solid wrapper and amdeep into coding. The only problem is a noticed VARCHAR fields being drawnfrom SQL Server 2000 are being truncated to 255 characters.I searched around php.net and found the following :Note to Win32 Users: Due to a limitation in the underlying API used by PHP(MS DbLib C API), the length of VARCHAR fields is limited to 255. If youneed to store more data, use a TEXT field instead.(http://www.php.net/manual/en/functi...ield-length.php)The only problem with this advice is Text fields seem to be limited to 16characters in length, and I am having similar results in terms of truncationwith other character based fields that can store more than 255 characters.I am using PHP 4.3.3 running on IIS using the php_mssql.dll extensions andthe functions referenced here http://www.php.net/manual/en/ref.mssql.php.What are my options here? Has anybody worked around this or am I missingsomething obvious?James

Problems Moving Data Over 8000k In DB2 Varchar Column Into SQL Server Varchar(max) Using SSIS
Nov 20, 2007
I have looked far and wide and have not found anything that works to allow me to resolve this issue.
I am moving data from DB2 using the MS OLEDB Provider for DB2. The OLEDB source sees the column of data as DT_TEXT. I setup a destination to SQL Server 2005 and everything looks good until I try and run the package.
I get the error:
[OLE DB Source [277]] Error: An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available. Source: "Microsoft DB2 OLE DB Provider" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".

[OLE DB Source [277]] Error: There was an error with output column "LIST_DATA_RCVD" (324) on output "OLE DB Source Output" (287). The column status returned was: "DBSTATUS_UNAVAILABLE".
[OLE DB Source [277]] Error: The "output column "LIST_DATA_RCVD" (324)" failed because error code 0xC0209071 occurred, and the error row disposition on "output column "LIST_DATA_RCVD" (324)" specifies failure on error. An error occurred on the specified object of the specified component.
[DTS.Pipeline] Error: The PrimeOutput method on component "OLE DB Source" (277) returned error code 0xC0209029. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.
Any suggestions on how I can get the large string data in the varchar column in DB2 into the varchar(max) column in SQL Server 2005?

Column Length Help
Sep 4, 2007I have a table this is populated by a flat file. In the desc field from the flat file some of the data is very long up to 150 characters in length. I have to export this data after some transformations to a fixed width file. I need to check the length of the data in the desc field and any thing that is to long needs to be put in a desc2 field, however any values in desc that are shorter than 36 characters in length needs to have spaces padding it up to 36 characters as well as the desc2 field. Any help would be great. I am not the best T-SQL programmer in the world and have limited time to get this done.

Jul 11, 2007Hello Friends,
I am working on a web application and using Sql Server 2005 as a Databasew. I want to define a variable with the datatype as defined in the database. Let me give an example.

String getFirstName;
Now this variable has to be stored into the table "Person" into the column "FirstName" which is of type "nvarchar" and having length "20" So I want to get this length programatically so that I can assign this number (20) to the maxlength property of the textbox "txtFirstName" so that in future if the legth of the database column changes it should no be needed to change in code also.
Caqn it be done? If yes please let me know.

Problem With WHERE Clause When Column Length &> 255
Mar 25, 2004Hello, I am using the JDCB-ODBC driver for my app, but one of the columns in my WHERE clause is 255 characters long. Because of this no rows are returned even though the statement should return 1 or 2 rows. I've tried other JDBC-ODBC drivers too and they have the same problem. Additionally, I've tried using RTrim(), Substring(), etc and it still will not work....any ideas? Is it a driver bug? Anyone know of a driver that will work?
Sample code....
ResultSet rs = dbRetrieve.getStatement().executeQuery( sql ) ;
if (rs.next()) {
// Never gets here
}
Thanx!
