View 3 Repliesi am migrating access database to sql server2005.
there is field with datatype "MEMO" in access.
can anebody tell me what is the compatible datatype for memo in sqlserver2005
I tried with varchar,varchar(max).
the field in access database conatains large comments
I have an access database that I am about to move over to SQL Server. In there I have member table that has a memo field. This table has the potential to grow quite big. My question is: what issues does having a large text field have on my database. Will it slow down my updates, searches or inserts? I plan on using this field for such things like a biography of the member. Is using a text field the best way to go, or should I look at text files instead? Many thanks,
View 1 Replies View RelatedI have an Access application with various DB's linked together. One of the DB's contains a field, SOURCECODE, which was mistakenly entered in as an nvarchar(4000) field in MS Sql Server. When I link the table, Access converts it to a memo field.
There will never be more than 10 chars in that field. The company that created the DB says its will be too risky to change the data type. I need to link this field to another field that's a VARCHAR.
How can I do this? Access doesn't allow the CAST feature.
Our company is migrating a Microsoft Access 2010 backend database to a SQL Server 2008 database. One of the memo fields in the Access backend can store up to 150 Kb of Unicode data. To store this data in SQL server, we found that we can use the following data types:
ntext = (2^30) - 1 = 1,073,741,823 bytes.
nvarchar(max) = (2^31) - 1 = 2,147,483,647 bytes.
Because ntext will be deprecated in future releases of SQL Server, the only good alternative to store an Access memo field in SQL server is to use nvarchar(max), which is what Microsoft recommends for large Unicode texts.Storing a large amount of text like 150 Kb in an nvarchar(max) field using only SQL server works as expected. However, if Access is used to store the data in a table linked to SQL server, the maximum number of characters allowed is only 4000. We found that this limitation is imposed by the ODBC driver that limits nvarchar(max) to 4000 characters.
The connection string we are currently using to link a table to SQL server is this:
ODBC;DRIVER={SQL Server Native Client 10.0};SERVER= SQLEXPRESS;DATABASE=TestDB;Trusted_Connection=No;UID=uid;PWD=pwd;
Any solution for this limitation storing large amounts of data in a Microsoft Access memo field mapped to an nvarchar(max) data field in a SQL Server database?
I'm having some problems importing data from a memo column (Access) into varchar column in SQL Server.
My idea was to use slowly changing dimesion to identify modified and new rows. No matter what data type I use to convert the memo column (using Data Conversion Transformation) and then using the converted column in SCD, I get the following error :
'The SCD transform does not allow mapping between columns of different types except for DT_STR and DT_WSTR.'
What do I have to do to get Memo column 'to behave' as a string?
Same problem with a different data type - decimal (18,5) in sql server - no matter what datatype I use in Data Conversion Trans, I get the same error trying to generate scd.
Thank you for your answers.
I'm using DTS to import data from an Access memo field into a SQL Server ntext field. DTS is only importing the first 255 characters of the memo field and truncating the rest.I'd appreciate any insights into what may be causing this problem, and what I can do about it.Thanks in advance for any help!
View 4 Replies View RelatedI have one column in SQL Server 2005 of data type VARCHAR(4000).
I have imported sql Server 2005 database data into one mdb file.After importing a data into the mdb file, above column
data type converted into the memo type in the Access database.
now when I am trying to import a data from this MS Access File(db1.mdb) into the another SQL Server 2005 database, got the error of Unicode Converting a memo data type conversion in Export/Import data wizard.

I know that memo data type does not supported into the SQl Server 2005.

Hi,
I'm importing an Access database to SQL Server 2000.
The issue I ran into is pretty frustrating... All Memo fields that get copied over (as Text fields) appear to be fine and visible in SQL Server Enterprise Manager... except when I display them on the web via ASP - everything is blank (no content at all).
I didn't have that problem with Access, so I ruled out the possibility that there's something wrong with the original data.
Is this some sort of an encoding problem that arose during database import?
I would appreciate any pointers.
Hi all,
i've a reasonable amount of experience with MS Access and less
experience with SQL Server. I've just written an .NET application that
uses an SQL Server database. I need to collate lots of data from around
the company in the simplest way, that can then be loaded into the SQL
Server database.
I decided to collect the info in Excel because that's what most people
know best and is the quickest to use. The idea being i could just copy
and paste the records directly into the SQL Server database table (in
the same format) using the SQL Server Management Studio, for
example.
Trouble is, i have a problem with line feed characters. If an Excel
cell contains a chunk of text with line breaks (Chr(10) or Chr(13))
then the copy'n'paste doesn't work - only the text up to the first line
break is pasted into the SQL Server database cell. The rest is not
pasted for some reason.
I've tried with MS Access too, copying and pasting the contents of a
memo field into SQL Server database, but with exactly the same problem.
I've tried with 'text' or 'varchar' SQL Server database field formats.
Since i've no experience of using different types of databases
interacting together, can someone suggest the simplest way of
transferring the data without getting this problem with the line feeds?
I don't want to spend hours writing scripts/programs when it's just
this linefeed problem that is preventing the whole lot just being
cut'n'pasted in 5 seconds!
cheers

Hi,
Can anyone point me any solution how to export a MEMO field from an Access database to a TEXT field from an MS SQL Server 2000. The import export tool from SQL server doesn't import these fields if they are very large - around 9000 characters.
Thanks.

which is to parse a create table script using Microsoft.SqlServer.TransactSql.ScriptDom namespace..I get a list of statements : StatementList SQLStatement = parser.ParseStatementList(StreamReader, out errors);then I cast a relevant statement to the CreateTableStatement type which gives me access to the ColumnDefinition class.
foreach (TSqlStatement T in SQLStatement.Statements)
{ if (T is CreateTableStatement) { CreateTableStatement TC= (CreateTableStatement)T}}
with foreach (ColumnDefinition CD in TC.Definition.ColumnDefinitions)
I am ready to loop through the columns so far so good. I can get to the column name using CD.ColumnIdetifier.Value, to the data type using CD.DataType.Name.BaseIdentifier.Value, but can't seem to get to the length definition. Meaning, I can get column1 , varchar; but I need column1, varchar(40). where do I get (40) from?I tried using ScriptTokenStream under C.DataType, but it seems to iterate through all tokens not just ones relevant to that fragment.
Hi,
on a migration from access 97 to SQL Server 7.0 columns in access like 'hyperlink' are converted to datatype 'text' on the SQL Server 7.0. Now I miss the function in the access application I had before with fields like 'hyperlink'. Now I can't start e.g. a word document with a click and I have to type in the hyperlink manualy.
Does anyone had the same problem an possibly have a resolve?
Thanks.

Hello,
My datalayer of C# code is invoking a stored procedure that returns a varchar(max) SQL data type. In my ASP.NET code, I have:
SqlCommand myCommand = new SqlCommand("usp_GetTestString", myConnection);
myCommand.Parameters.Add(new SqlParameter("@TestString", SqlDbType.Text));
myCommand.Parameters["@TestString"].Direction = ParameterDirection.Output;
myConnection.Open();
myCommand.ExecuteNonQuery();
return Convert.ToString(myCommand.Parameters["@TestString"].Value);
The query fails to execute and returns an error: String[1]: the Size property has an invalid size of 0. If I change the SqlDbType.Text parameter type to SqlDBType.Varchar, 100 (or any other fixed varchar length), it works but limits the length my unlimited field text. Any suggestions on how I can use db type text or varchar(max)? The field I need to retrieve is string characters of unlimited length and
hence the datatype varchar(max).
Hi, currently i am doing discussion forum for my project.
What I want to ask is what data type that I have to set for the message. Previously I am using nvarchar which I thought it would be ok, but when the time I save the message the ENTER command is become space in the database. For example I type
Message 1
Message 2
When I save into the database it become
Message 1 Message 2

I have several memo fields in Access, whenever I use DTS to import the data into SQL,
These MEMO fields gets truncated.
Any tricks or suggestions?

I am updating a Sql Server 7.0 DB to Sql Server 2005 Standard
I have to update Sql Server tables with Paradox 4.5 (DOS) data,
with DTS in 7.0 this was no problem.
In Visual Studio I use the OLE DB Jet 4.0 driver with the extended property "Paradox 4.x"
The package runs well if there is no Memofield or the Memofield has only a few characters.
If there is an Memofield filled with more than 250 Characters the preview and the data flow faults.
If I use "DBASE IV" on a dBase-table there is no error, but the NTEXT-Field in Sql Server has only one character " "
What can I do to get Paradox-data with Memofields?
Other problem:
I am missing the OLE DB Jet 4.0 Data Source in the Import/Export-wizard in
Sql Server Management Studio.

can this datatype hold formatted?? e.g. carriage returns?
View 3 Replies View RelatedI'm trying to create a site which allows me to add Memo type fields but when I insert or edit my record it will not take any of my text after an enter (vbNewLine).

Hey guys. I have a SQL query I'm trying to create. It's nice and dandy, but I have a memo field that's being trunicated to 256 characters.
SQL is something like this:
Code:
Select distinct `group`,sortorder,HideLabel,category,img,Description,Null as num,Null as subcat
from catalogimages
where Inact=0 and subcateg is NULL
group by `group`,sortorder,HideLabel,category,img,Description
order by `group`,sortorder,category
Description would be the memo field.
Is the 'GROUP BY' clause even necessary here?
I'm also willing to bet that the 'DISTINCT' clause might not be necessary.
Any help would be greatly appreciated.

Hello All,
Does anyone know how to convert data in a Memo field from Foxpro into a Text field in SQL table? Straight import via DTS package seems to entirely ignore this memo field and result in blank.

Good afternoon,
I have an issue with an ssis variable datatype.
The scenario is as follows:
I have a stored procedure:
PROCEDURE [dbo].[sp_newTransaction]
@sourceSystem varchar(50),
@txOut NUMERIC(18,0) OUTPUT
AS
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
Thanks much,

I have an application written in Access 97 that connects to a SQL2000backend. One field is a description field that is a data type NTEXT in theSQL database. In my access form, I can not enter more than 255 characters.Before I converted the backend to SQL, the description field was a memofield in Access.What do I need to do to make it so I can enter more text into this field?
View 1 Replies View RelatedI have used DTS in SQL Server 2000 to import an MDB filed (MS ACCESS) of a table. When the table is imported the primary key is lost and the memo field data is completely gone.
I use the tranformation option in the DTS wizard to add the primary key and make sure the data type for the memo field is varchar and has a size of 8000. I need that large size since I am storing lots of html code.
When I preview the data I see the html code that is supposed to get imported. However, when I return all rows from the table in Enterprise Manager the field is empty.
So I tried to manually copy the data from the MS Access Database into SQL Server. Could not figure out if SQL Server has an interface like MS Access to simply copy data into a table. So I linked to the tables from MS Access to the SQL Server table.
When I opened the linked table I see the data in the description field. However, if I return the rows from within SQL Server no data is present.
I have some ASP code trying to read the data in the SQL Server table. However, nothing is returned and when I run the SQL Statement, nothing gets returned. The SQL statement returns all rows. All the other data is present but nothing in the description field.
What am I doing wrong? Any suggestions anyone, please!
TIA

Hi,
I imported a table from Accees to SQL 7 with data in it.
I need to modify one of the datatype columns to "datetime" from nvarchar.
I tried to convert it manually, in SQL Server Enterprise Manager tool, but it gave me an error.
I also tried, creating another column "DATE2-datatype:datetime" and updating the column with the old one.
UPDATE users SET DATE2 = DATE.. But it also faild,..
How can I modify the column?
Thank you.
HI,I have a table with IDENTITY column with the datatype as INTEGER. Nowthis table record count is almost reaching its limt. that is totalrecord count is almost near to 2^31-1. It will reach the limit with inanother one or two months.In order to avoid the arithmentic overflow error 8115, we would likechange the datatype from INT to BIGINT. we hope this will solve ourproblem.How do I approch this datatype conversion?. Since the data count ishuge, that leads to a long down time of database.we need better approach or solution for this problem?. kindly give mea better solution that will reduce the total downtime of the productiondatabase.?.Regards
