Re: Howto dynamically set "Start with" value on a sequence in Oracle

18-Mar-09 22:29

I want to create a sequence in Oracle, and I want the start value to be the same as the value in another sequence.

This doesn't work:

CREATE SEQUENCE CUSTOMERID_SEQ 
  MINVALUE 1
  MAXVALUE 99999999
  INCREMENT BY 1 
  START WITH (SELECT THAT_OTHER_TABLESPACE.CUSTOMERID_SEQ.NEXTVAL FROM DUAL)
  NOCYCLE
  NOORDER
  NOCACHE

As there can be no subqueries in a Create Sequence

Any hints?

cant be done .. at least, not like this - start has to be an integer (so it doesnt even evaluate your select clause)

I could do it from c++ using oci - I'd do a [SELECT THAT_OTHER_TABLESPACE.CUSTOMERID_SEQ.NEXTVAL FROM DUAL] into an integer variable and then use that variable as a replacement into a create statement and execute the create statement.

Sorry, likely not what you were looking for ...

I wonder if it's possible to do that in pl-sql?
Then it could be saved to a script.
Thanks for the idea!
I'll try it this afternoon.

it should definately be do-able in pl-sql

Create and Execute a control flow task withing the Script task in SSIS

19-Mar-09 5:30

For anyone interested, this is one way that works:

DECLARE
  SEQ_ID NUMBER;
BEGIN
  SELECT AN_OTHER_TABLESPACE.CUSTOMERID_SEQ.NEXTVAL INTO SEQ_ID FROM dual;
  
  EXECUTE IMMEDIATE 'CREATE SEQUENCE CUSTOMERID_SEQ
  MINVALUE 1
  MAXVALUE 99999999
  INCREMENT BY 1
  START WITH ' || SEQ_ID || '
  NOCYCLE
  NOORDER
  NOCACHE';
END;

Roll backing the server

Hello Friends,

I am in trouble while loading data to SQL Server. i am using bulkcopy code to load datas.

I dont have much knowledge with SQL

While loading, if error occurs (in xtreme cases) loading wont be perfect(ie I having four tables to be loaded. error may occur while loading the fourth table. for me its like corrupting the tables. because for tables are interconnected)

So if error occurs i want to roll back other three tables to last state.
The below code is i used for loading and these function is calling four times for updating four tables

Can Rollback property be applied to the below code?? Please do help

Or any other way to prevent the tables from getting corrupted

------------------------------------------
Public Function rb_BCP(ByVal Server As String, ByVal Database As String, _
ByVal Table As String, ByVal FileName As String)

Dim objServer As SQLDMO.SQLServer
Dim objBCP As SQLDMO.BulkCopy
Dim objDB As SQLDMO.Database

On Error GoTo ErrorHandler
Set objServer = New SQLDMO.SQLServer
Set objBCP = New SQLDMO.BulkCopy

objServer.LoginSecure = True
objServer.EnableBcp = True
objServer.QuotedIdentifier = True
objServer.Connect (Server)

Set objDB = objServer.Databases(Database)

With objBCP
.UseExistingConnection = True
.DataFilePath = FileName
.RowDelimiter = vbCrLf
.IncludeIdentityValues = True
.ServerBCPKeepNulls = True
.DataFileType = SQLDMODataFile_SpecialDelimitedChar
.ColumnDelimiter = "|"
.IncludeIdentityValues = True
.ImportRowsPerBatch = 1000000
'Below speeds things up
'but does not log the bulk copy operation
'comment out if this is not what you
.UseBulkCopyOption = True
End With
objDB.Tables(Table).ImportData objBCP

Set objBCP = Nothing
objServer.Disconnect
Set objServer = Nothing

Exit Function
ErrorHandler:
MsgBox "Error " & Err.Number & vbCrLf & Err.Description

End Function

Hello.

Im running a webserver with apache and mysql 5.xx
Now I want to connect to the MySQL database on a server outside my own. But it doesnt allow remote connections from my mysql database.
I have port 3306 open and the firewall off.

How can I setup MySQL to accept remote connection?

Best Regard
Mads

Did you check the "Enable TCP/IP connections" option when you run the instance configuration? If not you can just reconfigure.

I installed it together with wamp.
And can't find such just thing in the mysql.ini .. What do I have to change in the mysql.ini to enable TCP/IP connections ?

I use windows for hosting mysql..
I have tried look in my.ini for these bind-adress and the other configs.. But can't find anything at all in my.ini that seems to have something to do with TCP/IP configuration.

Why SQL "blocks" when it cannot connect to a server? I would want it to return immediately on failure. Connection-timeout attribute looks like useless. I gave it as 5 seconds, but it continues to block for an eternity. Any help?

Please Explain in Detail what is your Problem

Vuyiswa Maseko,

Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

I thought I explained enough. Anyway here I go:

1. There's an SQL server waiting for you to connect. It's address it 123.134.1.2.
2. Now your application connects, uses DB, finally closes connection. Fine.
3. Now server shuts down, restarts. It's IP is 123.134.2.3 (changed)
4. Your application tries to connect to the old address 123.134.1.2, which doesn't exist.
Waits,
Waits,
Waits,
Waits,
Waits,
Waits,
Waits,
Waits,
Waits,
5. Throws a DB exception (May be wrong server/network error)

I want to remove

Waits,
Waits,
Waits,
Waits,
Waits,
Waits,
Waits,
Waits,
Waits,

and want it to throw the error immediately.

Why do you use an IP ? Because it changes, why dont you use its name ?
