Hi
I have two databases that are merged using replication, and I want to change the length of one of the fields. Can anyone think of a way of doing it that doesn't require dropping the whole publication and rebuilding it? Thanks Ed
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!
View 2 Replies View RelatedI 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.
Hi all,I need to change a varchar from 35 to 50. In the SQL Server books online it says that SQL Server actually creates a new table when youchange the length. I ran a test in a test database and it appears theonly thing that changes is the length. All the data remains in tact.The table with the column I want to modify is very critical. Is thereany chance I would loose data if I change the length to a larger size? Iam making a back up of the table just in case. Thanks,Kelly
View 2 Replies View RelatedI have a field in a table
FormID nvarchar(6)
i want to change the length of the datatype to nvarchar(8).
what is the best way to do with out dropping the table?
Hello all, I'm using SQL Server 2000 and have about 250 stored procedures that use an EMPLID parameter or variable of type varchar with a length of 4. I need to change the length to 10 instead and would like to do so without having to open every sp for editing. Is there a way to do this through SQL Server 2000? Does anyone have a script to do this? Any help would be appreciated.

Can I increase the length of a varchar column of table involved in transactional replication without dropping and recreating publication/subscription?
Any help/short-cuts/undocumented features greatly appreciated.

Hi,
I am trying to import data from Oracle RDB into SQL Server 2005 using SSIS. Created a ODBC data source to connect to Oracle and used DataReader Source component and ADO.net to connect to the ODBC data source.
Under the Component properties tab, the SQL Command looks something like this.
Select ID, ADDRESS, REVISED from ADDRESS
The data type for the source columns are Integer, Varchar(30) and DATE VMS.
Now when I look at the Input and Output properties window,
The External columns has the following data types.
ID - four-byte signed integer [DT_I4]
ADDRESS - Unicode string [DT_WSTR], length = 0
REVISED - database timestamp [DT_DBTIMESTAMP]
The Output columns has the following data types
ID - four-byte signed integer [DT_I4]
ADDRESS - Unicode string [DT_WSTR], length = 0
REVISED - database timestamp [DT_DBTIMESTAMP]
When I tried to change the length of the ADDRESS on the output column, I get the following error.
Error at Data Flow Task [DataReader Source [1]]: The data type of output columns on the component "DataReader Source" (1) cannot be changed.
Error at Data Flow Task [DataReader Source [1]]: System.Runtime.InteropServices.COMException (0xC020837D)
at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.SetOutputColumnDataTypeProperties(Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)
at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostSetOutputColumnDataTypeProperties(IDTSManagedComponentWrapper90 wrapper, Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)
Is this the default length for the Unicode string type. I was not able to load the ADDRESS column as it gets truncated before I load it into destination. Even if I use Derived or Data Conversion transformation, the ADDRESS is getting truncated before it reaches this transformation.
Any thoughts.
Thanks,
SK
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

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

Hey all.
I'm looking around for a solution on how to pull records back based on legnth.
So, if field A is more then 2 characters, return that row.
Thanks

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?

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?

Hi, all
I am seting up a table with email message, I am wondering what is the max length for varchar field. I am so reluctant to use text field, since when

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.

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?

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!

Hello,
I am running a stored procedure thru' isql.

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. The problem is when I use the wizard to specify the starting and ending of each column, its not allowing me to specify the columns beyond the position 4095.
Is there a limitation on this? if so is there a work around ? to solve this.
Any help on this is truly appreciated.
Thanks much. :)
I have a field Char(10) named bank, and another one Char(15) named namebank.
I need to create a TSQL query, but i need to preserve the white space on my first field named bank and concatenate with the other namebank, this last i dont need white space.
B001 Bank 123
How can accomplish this query.
How to limit the length of a database field such that only first 12 characters are shown in the result?
For example, I have show the only first 12 characters of employee name.
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.
Hi All,
Is there a way to check the data type and the maximum length of a field?
