Re: Case-Sensative Password Column in SQL Anywhere 10

25-Feb-10 3:51

Thanks for the feedback guys.

After some discussion it's been asked of me to find out if there is any way of setting the actual column in the database up as a password column in some way. Is there any contraint/switch in sybase that will serve what I'm looking for?

Thanks again

I'm not sure what you mean by this. Maybe this article will be of help:

http://ianywheresolutions.net/developer/product_manuals/sqlanywhere/1000/en/html/dbdaen10/da-security-s-4649816.html[^]

This obviously leaves you with the problem of how to secure the key used to encrypt and decrypt the password; I for one don't much like the idea of hard-coding it into the trigger like this. But it's a start.

This is for SQLAnywhere, which I think you said you were using. If it is Sybase ASE there is a more sophisticated method for doing this sort of thing which is explained in the documentation.

SSIS Connection Problem in C#

3-Mar-10 4:37

Hi David,

Thanks for the link above. I was wondering if you or anyone else could help with a problem I've came into with it though.

I was able to encrypt the password field using the following trigger when a new record was added to the table:

ALTER TRIGGER "encrypt_new_user_pwd" BEFORE INSERT
ORDER 1 ON "QAS"."tableName"
REFERENCING NEW AS newPwd
FOR EACH ROW
BEGIN
Set newPwd.pwdField = ENCRYPT(newPwd.pwdField , 'key')
END

The problem is I'm unable to decrypt the password of the newly created record (fieldID = 0002), using the following:

SELECT CAST (DECRYPT(pwdField, 'key') AS VARCHAR(100))
FROM "QAS"."tableName" WHERE fieldID = '0002'

In Sybase when trying to execute the above statement I get the following error:

Interactive SQL
The following error occurred while fetching results:
Decryption error: Input must be a multiple of 16 bytes in length for AES
SQLCODE=-851, ODBC 3 State="08001"

Do you have any idea what is going wrong here?

The pwdField is of type VARCHAR and size 15.

Thanks,
Mel

Hi all
how can i get Primary key column name from table?I find some tips from google but it's not working always show no row selected.

select all_constraints.index_name, all_ind_columns.column_name, all_ind_columns.column_position from all_constraints, all_ind_columns where all_constraints.owner = all_ind_columns.index_owner and all_constraints.constraint_name = all_ind_columns.index_name and all_constraints.constraint_type = 'P' and all_constraints.owner = 'DBO' and all_constraints.table_name = UPPER('VARTABLE') order by all_constraints.index_name asc, all_ind_columns.column_position asc, all_ind_columns.column_name asc

please help me.

Goood Day All

I have a SSIS package that i have created and i want to execute in C# in my web Application. and i have a Connection manager named "OMEGA" and in my C# am trying to execute it like this

//Start the SSIS Here
Application app = new Application();
Package package = null;
package = app.LoadPackage(@"C:\O!WEB_SETUP_VERSIONS\SSIS_Compiled\OMEGA.dtsx", null);
Variables vars = package.Variables;
vars["Time1"].Value = time;
vars["Time2"].Value = time;
vars["Time3"].Value = time;
vars["TTBLTYPE"].Value = THREAD_DATA[1].ToString();

ConnectionManager Omega = package.Connections.Add("OLEDB");
Omega.Name = "OLEDBConnection";
String Strcon = obj.GetConnectionString(THREAD_DATA[0].ToString());
Omega.ConnectionString = Strcon;

//package.Connections["SQLNCLI10.1"].ConnectionString = obj.GetConnectionString(THREAD_DATA[0].ToString());
//Excute Package
Microsoft.SqlServer.Dts.Runtime.DTSExecResult results = package.Execute();
String Log;

if (results == Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure)
{
foreach (Microsoft.SqlServer.Dts.Runtime.DtsError local_DtsError in package.Errors)
{
// Log = local_DtsError.Description.ToString();

//CommonFunctions.writeLogFile(Log,true);

}
}

}

After it executed the package, when i loop through the exceptions i get this

SSIS Error Code DTS_E_OLEDBERROR.   An OLE DB error has occurred. Error code: 0x80004005.\r\nAn OLE DB record is available.   Source: \"Microsoft SQL Server Native Client 10.0\"   Hresult: 0x80004005   Description: \"Login timeout expired\".\r\nAn OLE DB record is available.   Source: \"Microsoft SQL Server Native Client 10.0\"   Hresult: 0x80004005  Description: \"A network-related or instance-specific error has occurred while establishing a connection to SQL Server.

Source: \"Microsoft SQL Server Native Client 10.0\"   Hresult: 0x80004005   Description: \"TCP Provider: No connection could be made because the target machine actively refused it.\r\n\".\r\n

Please note that i want to use my webconfig not SSIS Config. in the Function GetConnectionString i return a Connection string and Pass it to the package.

Thanks

1: Is the connection string correct?
2: Do you have the requisite permissions?
3: Check the SQL configuration via the Sql Server Configuration Manager (was called somehting else in 2005: maybe Surface Area something or other) and ensure that it is set up correctly for your installation.
4: AS I recall the error you have listed is quite common: a quick search on Google would yield plenty of results. Here is one I found in about a second: TCP Provider: No connection could be made because the target machine actively refused it [^].

There aren't any dates between 23 feb 2010 and 23 feb 2010. Thats why youre query doesn't return anything. Try:

select * from tablename where startdate between '23-Feb-2010' and '24-Feb-2010'

The idea is good, the suggestion isn't. There still isn't any date between those when treated as exclusive.

His startdates where:

startdate="24-Feb-2010 4:00PM"

So the first one is between the 23th and the 24th, isn't it?

Read the documentation for your database.

http://www.w3schools.com/sql/sql_between.asp[^] says:

"In some databases, persons with the LastName of "Hansen" or "Pettersen" will not be listed, because the BETWEEN operator only selects fields that are between and excluding the test values).

In other databases, persons with the LastName of "Hansen" or "Pettersen" will be listed, because the BETWEEN operator selects fields that are between and including the test values)."

Re: DateTime ; between query in SQL SERVER 2000 [modified]

23-Feb-10 3:21

. No

store date/time information as real DateTime, not as string, not as separate date and time.

But be aware that "between" may or may not exclude the values you specify, i.e. depending on the database "BETWEEN a and b" means "a <= x <= b" or "a < x < b"

On Oracle you could try

select * from tablename where trunc(startdate) between '23-Feb-2010' and '23-Feb-2010'

There is likely an equivalent for SQL Server.

[EDIT]
I'd also add that you are asking for a compare between two different database types so an implied conversion will take place. That conversion often causes results to be different than expected. Smile | :)
