Problem Unicode Data 0x2300 In SQLServer 2000 SQLServer 2005 Express

Sep 20, 2006

Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))

Insert Data
insert into testunicode (Bez)values('Œ€„¢')
with 2 Unicode characters
Œ€ = 0x2300
„¢ = 0x2122

Selecting the data
select Bez from testunicode
I see
"?„¢"

„¢ = 0x2122 is ok but instead of 0x2300 there is 0x3f

When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'„¢')

and select again voila i see
"Œ€„¢"
Does anyone have an idea?

Thanks

SqlServer 2005 String Or Binary Data Would Be Truncated When Data Is OK

Feb 21, 2006

When using AquaData or JDBC (inet tds driver), when doing an insert using SqlServer 2005, I get error "String or binary data would be truncated" when the data is actually OK. There are no triggers, etc. that would confuse the situation. It works fine in SqlServer 2000.

The scenario is as follows:

Create table:
create table test3 (
name varchar (18) ,
tbname varchar (18)
)

Create and populate table:
create table maxtable (
tablename varchar (18) not null,
[...]
)

Try to insert into test3:
insert into test3 (name, tbname)
select i.name, o.name
from dbo.sysindexes i, sysobjects o, maxtable m
where i.indid > 0 and i.indid < 255
and i.id = o.id and i.indid = 1
and o.name = lower(m.tablename)

And I get the error "String or binary data would be truncated." The values being selected for i.name and o.name have maximum length of 18. There are other rows in sysindexes and sysobjects with longer values, but they are not being selected.

The error does not occur with SQL Server Management Studio, and does not occur using SqlServer 2000.

Check Data Changes In Table

Oct 27, 2007

Hi all!
I need to check data changes in some tables from specified date. Can it be done without triggers for each table?
SQL Server Management Studio always says "Data was changed" if another user updates data and you try to update old version. How it checks data modification date? I found only this:


USE [ScheduleDB]

GO

SELECT * FROM sys.objects WHERE object_id = OBJECT_ID('[dbo].[TTest]') AND type in ('U')

but it can only show structure modification date.

SQLserver 2005 -data Length 'max'

Jan 11, 2007

Hi all,

I ve few queries regarding SQLServer 2005, kindly help me to understand the things,

1. Datatypes like nvarchar, varchar, varbinary use 'max' to define their datalength,

a. is this 'max' always has the value of 2^31-1 ?
b. what other data types in sqlserver 2005 can use 'max' to define their datalength?

2. I defined a table (say 't') with a column 'name' of datatype nvarchar(max), now tried to execute the below query in the SQLServer client,

select column_name, data_type, character_maximum_length from information_schema.columns where table_name='t'

the result is,

+--------------+------------+--------------------------+
| column_name | data_type | character_maximum_length |
+--------------+------------+--------------------------+
| name | nvarchar | -1 |
+--------------+------------+--------------------------+

The question is why the datatype length is returned as -1, what happened to 'max'?
is there any other way to retrieve the actual data length (ie., 'max') from the table definition?

How To Use Xml Data From A Sqlserver Table In A Gridview

Jan 6, 2008

I have a products table in a Sql Server 2005 database.  One of the fields contains the products attributes in xml.  The most commonly used attribute is color.  An element of color is inventory.  This is the only way I could think of to maintain inventory numbers of each color of each product using someone else's (opensource) code.  An example of an attribute field would be <?xml version="1.0"?> <ArrayOfAttribute
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Attribute>
<Name>Color</Name> <Description>Shown in
Black</Description> <Selections> <AttributeSelection>
<FormattedValue>483 - Black</FormattedValue> <Value>483 -
Black</Value> <Inventory>25</Inventory>
</AttributeSelection> <AttributeSelection> <FormattedValue>484
- Lt. Tan</FormattedValue> <Value>484 - Lt. Tan</Value>
<Inventory>15</Inventory> </AttributeSelection>
<AttributeSelection> <FormattedValue>485 -
Pink</FormattedValue> <Value>485 - Pink</Value>
<Inventory>17</Inventory> </AttributeSelection>
</Selections> <SelectionType>SingleSelection</SelectionType>
</Attribute> </ArrayOfAttribute> How can I read this into the gridview control so that it makes sense to the user?Diane

Need Help Using Foreach Loop To Transfer Data From DB2/400 To SQLServer 2005

May 8, 2007

Hi, I am attempting to create SSIS packages to extract data from our AS/400 DB2 databases and populate tables for analysis and reporting in SQLServer. We have recently installed a new 2005 SQL Server to replace our existing 2000 databases. I have several DTS packages setup to connect to the 400s and copy the needed data to SQL2000 and these work great but do not transition to SSIS very well. I can get my SSIS packages to work if I create a seperate data flow task for each table but that does not seem appropriate for a tool like SSIS. I would think that what I am attempting is a very common thing to do. Maybe other enumerators could be used but I have not been able to get it to work.



I am trying to use a foreach loop, currently with a forech item enumerator, to first truncate the table on the SQL Server database using an Execute SQL task, and the to use a Data Flow task to refresh the data using an ole db source and destination. I have the truncate portion working, but when I try to setup the Ole db source using a variable it tells me I have no input columns. I have a variable from the forech loop that loops through the table names, this variable is used in a second variable which is set to EvaluateAsExpression with the expression set to the follwoing: "select * from " + @table_name



I have set delayvalidation to true and validateexternalmetadata to false. What do I do in order to get around this issue? Also, how should the old db destination be set so that it load the data into the table specified in the variable?



Thanks for any help you can provide.

How Do You Connect To Networked SqlServer 2005 Express Using The Add New Data Source Wizard

Sep 7, 2006

Hi All,

I want to connect to SQLExpress database on the network. I can do so using code but I want to use the Data Source Configuration Wizard. It seems this only works for local instances of SQL server. Is this true?

I can connect just fine to the database on the network using Microsoft SQL Server Management Studio Express...for what this is worth.

I have tried to map a drive to the SQL server machine and pick the mdf file but I get the error msg of network path is not supported for database files....I have turned on allow remote connections, allow tcp/ip, named pipes, added sqlserv.exe and sqlbrowser.exe to my firewall exceptions ect..

I want to be able to use Table Adapters, SqlDataAdapters ect. After reading numerous forum questions/ kb articles this seems to be a common problem. I am on the verge of just saying forget it and use MS Access instead.

Thanks in advance!

Trying To 'load' A Copy Of A SQLServer 2000 Database To SQLServer 2005 Express

Apr 18, 2008



I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.

I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?

The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.

Thanks!!

Integration Services :: Check Table For Existing Record Before Data Flow Task

Jun 1, 2015

Using SSIS 2012 (within Visual Studio) on Windows 7.

Before allowing my Data Flow task to fire, I'd like to check the target table (OLE DB Destination) for a specific date value in a specific field. I've seen how the Lookup Task is commonly used to check for dupes before inserting, but I'm not able to use that method because the data value I want to search the table for is contained in a Global Variable (let's say "MyVariableDate"). 

Is there any way to check for any records in a target table where Date1 = MyVariableDate (i.e. scanning the entire table for any occurrence of MyVariableDate in the Date1 field)?

Replacing Sqlserver 2000 With Sqlserver 2005 Express

Jun 14, 2006

I have an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000.

Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express? The app would still be using the sqlserver 2000 jdbc driver to try and make the connection.

If that is a possibility, what can be some differences in the configuration? Previously with 2000 the config information I entered is:

server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS"

DB name: name of db instance

port: 1433(default)

user and pass.

My attempts so far results in

"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket."

and

"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unable to connect. Invalid URL."

SQLSERVER 2005 X64 Linked Server To SQLSERVER 7.0

Jun 20, 2007

Hello people.

I am in the process of planning a server upgrade to sql2005 x64.

I created 2 linked servers: one to a SQL2000 sp4 server and one to a SQL7.0 SP3.

I have the following error when I query the linked servers.
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "Unspecified error".
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "The stored procedure required to complete this operation could not be found on the server. Please contact your system administrator.".
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "IVDM2K". The provider supports the interface, but returns a failure code when it is used.

I am aware of KB 906954.
http://support.microsoft.com/default.aspx?scid=kb;en-us;906954

I applied the instcat.sql on the SQL2000SP4 server and my linked server issues for that one are gone.

However, I ran the instcat.sql script on the SQL7.0 sp3 server and the linked server is still giving me an issue.

Can someone help me find a solution to this?
