What connection method used by SQLs embedded in C/C++?

Hello.

I've seen a lot of information on Pro * C and embedded SQL in C/C++ applications instructions.
But have not found any information - which method of connection it use?

Actually Pro * C replacement integrated SQL statements with all Oracle API calls.
Usually there are generated using "struct sqlexd" API calls sqlcxt() function and structure.
But which method of connection used by this approach?
You know - Java using JDBC, some programs use OIC but this is something different, so my question is that what the 'official name' of the connection method used by the Oracle API based on the sqlcxt() function?

Would also be good to know - where sqlctx() function is declared, defined? Which include, which library file?

Kind regards
Dmitry.

It's called SQLLIB according to 11.2 http://download.oracle.com/docs/cd/E11882_01/server.112/e16508/cncptdev.htm#BABDJCFJ Concepts Guide

  • What hearing method uses to determine the overal frequency?

    Hello

    No one knows which method uses Audition to determine the "global frequency" in the section "analysis of frequency? I need to know how is it calculated?

    Thank you very much!

    Thank you for this! So am I right in thinking "global frequency" is that point which contains the largest amount of energy in a sound sample given frequency?

    I don't know why it's called "global" frequency - seems a little strange to me, although you could call it although it is a bit of a mouthful, I'm not sure. But, strictly speaking, what is the frequency of the amplitude higher at this moment on the screen. It isn't really a sign you measure; It's a single FFT 'slice', which raises even more questions, as the sector size determines the resolution and therefore the accuracy of the result in any case.

  • What connection to use for faster printing

    I install my new of Officejet Pro 8600 today.  I have three options to connect, is a USB cable, ethernet cable or wireless.  To make the decision, I have a second remote desktop connected wireless to the internet and the usual iPhones.  My work horse is the computer that I will use often and want to have the fastest printing capabilities.  I still want to be able to print from the second remote computer too.

    Nothing in the HP documentation which addresses precisely this question.  What is the best connection should I use for this arrangement?  Your response would be greatly appreciated.

    TIA... John

    All of these out-rate connections greatly the mechanics of printing, so it's not really important.

    Between Ethernet and wireless, ALWAYS choose Ethernet if you can (no password, no interference, etc.).

  • Different results when contacting 11g DB using various connection methods

    Greetings:

    First of all, thank you in advance for any help you can provide.

    I'm looking for help to determine why certain methods of connection to a working DB production 11.2.0.3.0 64-bit, while others do not.  I tried 7 connection methods, some work, some give an ORA-12541: listener TNS:no error.  When connecting to a test instance, all 7 work very well.

    I'm not a server admin, but the following information obtained from them: both servers are running Linux RedHat Enterprise Server 5.10 (Tikanga).  Both run Oracle 11 g Enterprise Edition 11.2.0.3.0 64 bit.  Each is on a different subnet.  Each has a different DNS suffix up to the last section of the suffix, which is the same on both.  I don't know if the firewall rules are different.  Production server is a physical box, test server is a virtual machine.

    Results below are attempts to connect to the production server made from my Win7 64-bit workstation.  Once again, all attempts to test server are successful.

    Method                                                                                                      Result

    ODP.net 12.1.0.1.0 or 12.1.0.1.2 as an object in PowerShell 32 or 64 bit ORA-12541 .net

    . UDL file by using the provider, Oracle OLE DB of the ODAC 64bits 11.x or ORA-12541 12.x

    SqlPlus of Oracle Instant Client 11.x or ORA-12541 12.x

    Toad with entry in file TNSNames.ora success

    SQL Developer using the success TNSNames.ora file entry

    ODBC System DSN using Oracle 11 g pilot success

    TNSPing with entry in file TNSNames.ora success

    So, what's different in the methods of connection or network protocols between these methods that fail and those who succeed?  Our Oracle DBA has tried to help me and claims that the file of the listener on the server is correctly configured.  It seems to be useful, so I don't think it's brushing me off.  I did not have access to check it myself, so must continue in the event that it is.  So I'm assuming that the TNS listener error is generated because my traffic does not reach the DB rather than the listener being misconfigured file.  However, if

    My ultimate goal is to connect to prod using ODP.net in the PS script to make read-only SQL queries.  Works very well with the test, but of course, this data is not current.

    Thanks for any help! -EW

    EW, were all the client tries the same machine or different machines?  I hope your problem is either the entry in the file tnsnames.ora for connections of problem which can be different even from other tools on the machine even if multiple Oracle homes exists on the client.  Check the files tnsnames.ora entries.  If host names are referenced, verify that the client can recognize the hostname (DNS).  You may need to use an IP address instead.  Here's a more complete list of the possible causes of this problem.

    - -

    * Action:

    -If you are using local naming (TNSNAMES. ORA file):

    S ' ensure that "TNSNAMES" is cited as one of the values of the

    NAMES. DIRECTORY_PATH parameter in the Oracle Net profile

    (SQLNET. ORA)

    -Check that a TNSNAMES file. ORA file exists and is in good

    Directory and is accessible.

    -Make sure that the name of the network used as the connect identifier service

    It exists in the TNSNAMES file. ORA file.

    -Make sure that there are no errors of syntax anywhere in the TNSNAMES file. ORA

    file.  Search for unmatched parentheses or stray characters. Errors

    in a TNSNAMES file. ORA file can make it unusable.

    -If you use the directory naming:

    -Check that "LDAP" appears as one of the values of the

    NAMES. DIRETORY_PATH parameter in the Oracle Net profile

    (SQLNET. ORA).

    -Check that the LDAP directory server is in place and that it is

    accessible.

    -Check that the net service name or the database name used as the

    connect identifier is configured in the directory.

    -Check that the default context used is correct by

    by specifying a full network service name or a unique display name of LDAP

    as the login

    -If you use easy connect naming:

    -Check that "EZCONNECT" appears as one of the values of the

    NAMES. DIRETORY_PATH parameter in the Oracle Net profile

    (SQLNET. ORA).

    -Make sure that the host name, port, and specified service

    are correct.

    -Try putting the identifier of connection between quotation marks.

    As mentioned that a firewall between the client and the database can cause problems.

  • Need help, unable to connect to the ODBC database using the SQL Toolbox!

    Hi all

    I'm playing around with the evaluation of SQL Toolkit (2.2 + patch) and I'm having trouble.

    I ran the example 'connect' program and it seems to work fine.

    However, I try to write my own program, and I get the same message:

    "Service connection BD: (return value ==-10 [0xFFFFFFF6])."

    Native error - 2147467259 code 0x80004005

    The message is different from time to time, but the return value is constant.

    I use Microsoft SQL Server 2012 and MySQL.

    For MySQL, I installed the last Connector ODBC, 5.3.4. Inside the Control Panel / Data Sources (ODBC), I have a DSN called test_mysql in DSN user and system DSN.

    I ran a test on the connection and the test passes. I don't know if I have to use the ansi or unicode driver, I tried both with the same success.

    I do not know I had properly configured the SQL Server connection and who will try again.

    My Code CVI is quite simple:

    hdbc = connection BD ("DSN = test_mysql");

    Whenever I get a - 10 BD. Either I have something configured wrong or am I missing something.

    Does anyone have any suggestions?

    Update 2:

    After getting off the phone with Technical Support, the problem has been identified!

    LabWindows SQL Toolkit requires 32 bits DNS. My PC is a 64-bit, so my default DNS Manager in 64-bit.

    I needed to use the DNS Manager 32-bit when you work with the box tool.

    Once I created my DNS connections using the 32-bit version of the Datga ODBC Source manager, everything worked fine.

    Convert .xls in .csv file using pl/sql

    I know that it s a long time but just wanted to know if there is a way to convert excel .csv.

    I have a directory say 'F:\purple_top\ '. I'll get the .xls file in this directory. I need to change to .csv and tables load external oracle. Any ideas or advance coding on it since 2009 so far?

    A few other options might be:

    • Java code, which can be used from within Oracle, which makes use of utility libraries (e.g. Aspose.Cells) open source (for example Apache POI) or "save under" CSV, or read the source cells and their output to a CSV file.
    • COM Automation, using available open source (for example, JACOB or j-interop) or commercial libraries, which can automate Excel to open a XLS file and "Save as" a CSV file. In addition, Oracle has a feature of COM Automation (available since version 8 but abandoned after Oracle 11g). I have successfully used this read (non-macro-enabled) Excel files in PL/SQL.
    • Other approaches using Perl or PHP can be found by googling 'convert xls to csv.
