Insert into Oracle from Foxpro frontend

Have an insert from foxpro frontend, ODBC connection, will send everything except the unique identifier to ORACLE, get error message saying that I cannot insert a null value. So, created a sequence in ORACLE. Would like to place the unique identifier into a temporary table of some sort (I think a cursor would actually be the right approach) and then when a save occurs form foxpro save the new record with the unique identifier in the db table...I have tried a number of different approaches and this is the conclusion I have come to...except I don't know how to do it, if anyone is able to comment, would be much appreciated.
SE

Unless you have some business logic or requirements around the unique identifier, a trigger is the normal approach here.
You create an on insert trigger to get the next value from the seuqence and store it with the insert:

    I am very late to help you solve the query but following is the solution to 'Bulk Insert into Oracle' that worked for me.
    To use below code for SSIS 2008 R2 in a

    Prerequisites:
    1. C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies\Microsoft.SQLServer.DTSRuntimeWrap.dll
    2. Install "Oracle Data Provider For .NET 11.2.0.1.0" and add a reference to

  • Insert into MSSQL from Oracle

    Hello together,
    I'm a little bit frustrated. The follwoing is my problem:
    I want to insert some values from an Oracle 10gR2 database into a MSSQL database (SQL Server 2008 R2).
    Therefor I'm using DG4ODBC 11.2.0.3. The connection is working absolutly fine.
    I want to insert five values from five columns from oracle.table-a into a msssql table-b.
    But I'm hitting the error:
    Invalid character value for cast specification.
    Two columns from the oracle table are chars size 12 and 40, and three are number size 5.1, 5.1 and 4.
    The MSSQL column definitions are varchar40, varchar50, 2x float8 and int.
    The column assignments are:
    Oralce -> MSSQL
    a. char 12 -> varchar40
    b. char 40 -> varchar50
    c. number 5.1 -> float8
    d. number 5.1 -> float8
    e. number 4 -> int4
    The insert works greate for a,b and e but nor for c and d.
    I tried so many solutions (cast, to_binary_float, nls_character_format, nls_theritpory etc..) but nothing helps.
    I always hitting this error.
    Can anyone help me with this problem?
    cheers
    Joe

    Hi together,
    I fixed the problem. I multiply the origin number with 10. The result is a number without any comma. During the insert into MSSql I divide by 10.
    I now, this is a very strange solution but it works.
    Yes I know this helps only, because the column can only save number with one decimal place. For higher decimal places you have to multiple it with 100 or 1000 or......
    Hope this helps also other peoples.
    kind regards
    Joe

  • Best Practice to fetch SQL Server data and Insert into Oracle Tables

    Hello,
    I want to read sqlserver data everry half an hour and write into oracle tables ( in two different databases). What is the best practice for doing this?
    We do not have any database dblinks from oracle to sqlserver and vice versa.
    Any help is highly appreciable?
    Thanks

    Well, that's easy:
    use a TimerTask to do the following every half an hour:
    - open a connection to sql server
    - open two connections to the oracle databases
    - for each row you read from the sql server, do the inserts into the oracle databases
    - commit
    - close all connections

  • Unable to insert into oracle db using times ten

    I have a times ten 6.0 installation on my m/c connected to an oracle 10.2.0.2 database. The database is a remote database. My application is deployed to oracle application server (10.1.3.1 SOA). I am getting the following SQLException when I try to insert.the first row.

    I tried a select on the table before insert and it worked. Using ttisql I can insert into this table without any problem. Using a standalone java program I am able to insert data into this table. But from within an appserver I am facing this issue.
    Thanks in advance for any help.
    Regards,
    Mahesh.

    Jimmyb,
    Are you logged in as the user that owns that table?
    Yes.
    If yes, then there are no triggers on this table.
    That is true.
    You will need to populate the ID column with your insert statement.
    Just did that.
    Usually, the sequence is very similar to the table name.
    Yes I tried few of them in my sql query and it said "sequence cannot be found"
    Isn't there some way that it will list the name of the sequence currently being used in a table?

    Thanks!Hi,
    You'll want to read up on using parameters (also known as bind variables) - these are critical for scalability in an OLTP-type system and helping guard against SQL Injection attacks. There's many sources out there, but here's a link to the Parameter Binding section in the ODP.NET Developer's Guide which is probably a good thing to become familiar with:
    http://docs.oracle.com/cd/E11882_01/win.112/e23174/featOraCommand.htm#i1007242
    Here's your sample using bind variables:
    string oradb = "Data Source= oraDB;User Id=sm;Password=mypassword;";
    OracleConnection conn = new OracleConnection(oradb);
    conn.Open();
    OracleCommand cmd = new OracleCommand();
    cmd.Connection = conn;
    // Perform insert using parameters (bind variables)
    cmd.CommandText = "Insert into USER.EMPLOYEE VALUES (:1, :2)";
    // Here's one way to use parameters aka bind variables:
    // Create parameters to hold values from front-end
    cmd.Parameters.Add(new OracleParameter("1",
                                           OracleDbType.Varchar2,
                                           tbEmployeeName.Text,
                                           ParameterDirection.Input));
    cmd.Parameters.Add(new OracleParameter("2",
                                           OracleDbType.Varchar2,
                                           lbEmployeeGender.Text,
                                           ParameterDirection.Input));
    int rowsUpdated = cmd.ExecuteNonQuery();
    if (rowsUpdated == 0)
      MessageBox.Show("Record not inserted");
    else
      MessageBox.Show("Success!");
    conn.Dispose();
    // don't forget to perform any clean-up as necessaryNote that I've just typed this into a text editor and not verified, so please excuse any typos you may find.
    Also, I've allowed the default of OracleCommand.BindByName=false as I prefer that, though others certainly prefer setting it to "true". See the docs for what this means if you are not sure.

            java.sql.SQLException: Invalid operation for read only resultset: moveToInsertRowAlternatively (1) I have tried to have automatically generated rave connection pool / jdbc resources and copying over the driveradapter.jar but as we know that version is locked for embedded applications only (since Creator only includes the AppServer PE's driveradapter which cannot be deployed on WebServers).
    Alternatively (2) I have tried manually setting up the connection pool / jdbc resources and copying over the smutil.jar / smoracle.jar / smbase.jar but it complains about java.lang.ClassNotFoundException: com.sun.sql.jdbc.oracle.OracleDriver
    Is there a pain-free way to get Creator to play with Web Server 6.1 nicely? I seem to either run into Oracle THIN JDBC problems (main code above) or otherwise running into situations where Creator and Web Server 6.1 doesn't like each other (alternative 1 and 2).
    Thanks for your input

    Hi there, sorry for the trouble. I found the following thread:
    http://forum.java.sun.com/thread.jspa?forumID=48&threadID=417560
    I am using Oracle 8, I had followed the instructions in that thread and still get the error.. but you can ignore this thread for now I will pursue this in the other thread. Sorry for taking your time.

  • Can select, but cannot insert into oracle tables using php.

    I am having trouble inserting data into a tables in oracle using PHP. I can insert into the tables using baninst1, but nothing else. I can't even insert using the tables' owner. Every time I try I get the ORA-00492 error of table or view does not exist. However, I can run a select statement just fine. So far, baninst1 is the only user that can actually do inserts. I've triple checked all the table grants and everything is fine. Also, I can copy/paste the exact insert statement into SQL*Plus and it works with the correct user. It doesn't have to be baninst1. I've tried everything I can think of. I've tried putting the table name in quotes, adding the schema name to the table, checking public synonyms, but everything appears to be ok. I would greatly appreciate any suggestions others may have.
    I'm using PHP 5.2.3 with an oracle 9i DB.

    Here is the code that doesn't work. It works only with baninst1, no other username will work and all I do is change the my_username/my_password to something different. This is one example function where I try to do an insert, but it doesn't work on any of the tables I try.
    Thanks for looking.
