Change Length Of Field

Dec 31, 2012

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.

Change Field Length W/ Replication

Jun 15, 2001

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.

Transact SQL :: NVARCHAR Field Getting Truncated After Increasing Field Length?

Aug 28, 2015

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 -> 123456-8      *Correct
1234567-9 -> 1234567-     *Wrong
123456789 -> 123456789    *Correct
1234567#9 -> 1234567#     *Wrong
1234567a9 -> 1234567a9    *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.

What Matter Are There If I Always Set Big Length In Nvarchar Field?

Sep 29, 2006

There 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?

How To Insert A Zero Length String Into A Field Using SqlDataSource?

Jul 25, 2006

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.

Select Into Outfile: Wrong Field Length

Oct 29, 2005

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!

Hi,
I am trying to upload a fixed field text file to a sqlserver table using the DTS wizard. The txt file has 111 columns and the total length of a single row is 5897.

Is there a limitation on this? if so is there a work around ? to solve this.
Any help on this is truly appreciated.

Dynamically Changing The Length Of A Varchar(n) Field

Dec 26, 2006

Hi 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!

Union All Component Silently Changes Output Field Length

Jul 25, 2007

To simulate problem do follows:

1. Add Script source component.

2. Add 2 string output collumns: F1 length 50, F2 length 110

3. Add Union All component connected to Script source component

4. Add Script transformation component connected to Union All component

5. Mark F1 and F2 as input collumns

6. In the Input and Output section of the script transformation component check that length of the fields is 50 and 110 correspondingly

7. Edit Union All component: change Union All Input 1 to <ignore> for Output collumns F1, and F2; change Union All Input 1 to F2 for F1 and F1 for F2; change back <ignore> for F1, <ignore> for F2; set back F1 for F1, F2 for F2; Click OK to save

8. In the Input and Output section of the script transformation component check that length of the both fields is 110 now.



So, be careful to select output columns values in Union All component. If you choose wrong field by accident, and replaced it with correct one straight away, the length of output column could be stored not as you expect an need.

Transact SQL :: DATALength - Split A Field Based Off Its Length

May 15, 2015

I need to split a field based off it's length.  Initial thought was to take Left(field, characters), and Right(field, characters), but now I see I am duplicating the data as I am capturing too much of the data in.  However, what I actually need to achieve is in field1 capture the left 1000 characters, and in field 2 take from character 1001 to the end.  How can I update my syntax so that field2 will ONLY capture from character 1001 to end?

field1 = COALESCE(CASE WHEN DATALENGTH(exitinterviewnotes) > 998 THEN LEFT(CAST(exitinterviewnotes AS VARCHAR(MAX)), 1000) ELSE exitinterviewnotes END,''),
field2 = COALESCE(CASE WHEN DATALENGTH(exitinterviewnotes) > 998 THEN RIGHT(CAST(exitinterviewnotes AS VARCHAR(MAX)), 1000) END,'')

T-SQL (SS2K8) :: Procedure Parameter Length Declaration Less Than Column Length?

BlobColumn.GetBlobData() With Data Length &&> Integer Length (32767)

Mar 27, 2008

For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.

The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "&paramname=value&parm2=value..." format.

The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:

Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)

The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.

THIS IS A PROBLEM!!!

Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!

Thanks for your help in advance,
LOSTlover
