Hi,
I work on a project which convert a database access in mysql and I have a field
which has 9 Mb and when I try to convert this field in mysql I get the error:
Error:Unable to write to stream<br />
I put the mysql sintax:
set global max_allowed_packet=16777216
but it doesn't work.
Maybe I didn't put it right.
I put this command in my program.
Please help.
Thanks

You use a third table between the 2 tables you wish to have a many to many relationship between
Table1
-ID
Table2
-ID
Table1ToTable2
-Table1ID
-Table2ID
|
|
|
|
|
the 3rd table having the 2 columns will be composite primary key or foreign key or both.
Thanx
|
|
|
|
|
Both will be foreign keys
|
|
|
|
|
thanx for clearing my confusion

Use a varbinary(max) column type. Use that type in parameters when you add data to the database. When you select it the result will by a byte array in your .NET application.

1. check the authors tabls exists in the database
2. check whether you selected / pointed the right database

If you are just learning a better question would be "What does the error mean?" so you can understand what it means in the future.
SQL Server has a number of database objects. These include tables, views, stored procedures, functions and so on.
You can get a list of all object in the database by typing
SELECT * FROM sysobjects
The message "invalid object" indicates that the object either does not exist, or it is the wrong type of object for the context in which you are trying to use it.
In this case you refer to a table object in the SELECT statement that does not exist (there may be another object in the system called authors, but that will be a different type of object, or be used in a different context.

Hi all
i wana come to know that how can i return cursor from a stored procedure???
Regards
Qaiser
|
|
|
|

I think A cursor is a server side thing. You can't "return" this to a client.
Anyway why do u need this??

Why you need to return a cursor from a Stored Procedure ? I think you got confused with Oracle .. Is it ?

Hi All
i want to get top 5 records from the table. what would be the query?
Regards
Qaiser
|
|

Returning only the first N records in a SQL query differs quite a bit between database platforms. Here's some samples:
Microsoft SQL Server
SELECT TOP 10 column FROM table
PostgreSQL and MySQL
SELECT column FROM table<br />
LIMIT 10
Oracle
SELECT column FROM table<br />
WHERE ROWNUM <= 10
Sybase
SET rowcount 10<br />
SELECT column FROM table
Firebird
SELECT FIRST 10 column <br />
FROM table

I've created a dll (with vb6) to call a webservice, and this works fine when called in vb6.
I need to run this from stored procedure in SQL Server 2000,
because we have many clients that run application that access an SQL server.
It'll be hard work to install the dll into each of the clients pc (and many of them don't have MS SOAP installed), so instead I've been planning to install the dll in the server that runs SQL server, while others clients can just use store procedure to get the result from the webservice (which access to another SQL server machine).
We've tried using linked server but the response is too slow.
When I've tried to create store procedure to access the dll, it always return NULL value.
Anyone can help with this problem?
Thanks in advance,

Hi,
I have a stored procedure which is having a input parameter as TEXT datatype. I am passing a string to it whose length is 9000. It does not accept more then 8000 characters of the string. How to solve this issue?
Is there any method in which i can increase the length of the datatype. or is there any other datatype whose datalength is more then 8000?
Thanks,
Riz

to my knowledge 8000 is max. in SQL Server 2000

If you're using classic ADO, you must use the adLongVarChar datatype for the parameter, and use AppendChunk to write the data to the parameter rather than simply assigning the Value property.
For ADO.NET and the SQL Server data provider, use the SqlDbType.Text type.
