I am trying to update an existing record in a table using the following code in an ASP page. The table (tblProjectCats) has an ID value (integer, autoincrement), and Title and Description fields (both set to varchar). The following code just doesn't work...doesn't give an error message...

'//start code
Dim objConn, objRS
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open strConnect
Set objRS = Server.CreateObject("ADODB.Recordset")
objRS.Open "UPDATE tblProjectCats SET Title ='Title', Description = 'Desc' WHERE ID=1", objConn, adOpenDynamic, adLockReadOnly, adCmdText
objRS.Close
Set objRS = Nothing
objConn.Close
Set objConn = Nothing
'//end code

Try:

Dim objConn
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open strConnect

oConn.Execute "UPDATE tblProjectCats SET Title ='Title', Description = 'Desc' WHERE ID=1", , adExecuteNoRecords Or adCmdText

objConn.Close
Set objConn = Nothing

memo fields and other big fields

i have a MSAccess database (soon to be upgraded to SQL Server db)... which has Memo fields and some OLE and maybe even picture fields

in ASP... given a connection object (set cn = server.createobject("adodb.connection")), how do i update the data in the memo field to that of a variable

e.g. i want to do "UPDATE myTable SET myMemoField=<here i="" need="" to="" put="" like="" 50k="" of="" data=""> WHERE ... " but of course i can't fit that all into the string

and even if it did fit in the string, it screws up when i have SQL commands in the text data itself

thanks in advance for your help

I think you have to do it manually - write code to open recordset, call method Edit(), set value for your memo field and call Update().

When you will move to SQL server you might want to write stored procedures to update your database - you will get it very robust and probably faster.

Collation

With which SQL stored procedure I can get/set table or databse collation?

Re: Collation

From SQL BOL:

Changing Collations

You can change the collation of a column by using the ALTER TABLE statement:

CREATE TABLE MyTable (
   PrimaryKey   int PRIMARY KEY,
   CharCol      varchar(10) COLLATE French_CI_AS NOT NULL
)
GO
ALTER TABLE MyTable 
   ALTER COLUMN CharCol varchar(10)
   COLLATE Latin1_General_CI_AS NOT NULL
GO

You cannot alter the collation of a column that is currently referenced by:

A computed column.
An index.
Distribution statistics, either generated automatically or by the CREATE STATISTICS statement.
A CHECK constraint.
A FOREIGN KEY constraint.

You can also use the COLLATE clause on an ALTER DATABASE to change the default collation of the database:

ALTER DATABASE MyDatabase COLLATE French_CI_AS

Altering the default collation of a database does not change the collations of the columns in any existing user-defined tables. These can be changed with ALTER TABLE. The COLLATE CLAUSE on an ALTER DATABASE statement changes:

The default collation for the database. This new default collation is applied to all columns, user-defined data types, variables, and parameters subsequently created in the database. It is also used when resolving the object identifiers specified in SQL statements against the objects defined in the database.
Any char, varchar, text, nchar, nvarchar, or ntext columns in system tables to the new collation.
All existing char, varchar, text, nchar, nvarchar, or ntext parameters and scalar return values for stored procedures and user-defined functions to the new collation.
The char, varchar, text, nchar, nvarchar, or ntext system data types, and all user-defined data types based on these system data types, to the new default collation.

After a collation has been assigned to any object other than a column or database, you cannot change the collation except by dropping and re-creating the object. This can be a complex operation. To change the default collation for an instance of Microsoft® SQL Server™ 2000 you must:

Make sure you have all of the information or scripts needed to re-create your user databases and all of the objects in them.
Export all of your data using a tool such as bulk copy.
Drop all of the user databases.
Rebuild the master database specifying the new collation.
Create all of the databases and all of the objects in them.
Import all of your data.

Note Instead of changing the default collation of an instance of SQL Server 2000, you can specify a default collation for each new database you create.

This example returns the name of the default collation for the server.

SELECT SERVERPROPERTY('Collation')

This example returns the name of the default collation for the Northwind database.

SELECT DATABASEPROPERTYEX('Northwind', 'Collation')

Getting the collation for a column is not as easy. The only way I have found is to use the SQL_VARIANT_PROPERTY function. It's only supposed to work on sql_variant types, but it seems to work on other types as well.

SELECT TOP 1 SQL_VARIANT_PROPERTY(Column, 'Collation') FROM Table
