Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Sql insert statement

    trying to use an sql insert statement and trying to use on duplicate key update and get an error. here is my string

    Code:
    dim sqlInsertStatement as c 
sqlInsertStatement = <<%txt%
INSERT INTO contact  (idContact, fname, lname, phone, fax) VALUES (:idContact, :fname, :lname, :phone, :fax)
	ON DUPLICATE KEY UPDATE %txt%
    not matter what way I try i still get the error.

    i'm trying to insert data but if the pkey exsists it will update the remaining fields and not cause a dupelicate.

    this is the example i have to work with and mysql sends an error back."" INSERT ... ON DUPLICATE KEY UPDATE Syntax
    If you specify ON DUPLICATE KEY UPDATE, and a row is inserted that would cause a duplicate value in a UNIQUE index or PRIMARY KEY, an UPDATE of the old row is performed. For example, if column a is declared as UNIQUE and contains the value 1, the following two statements have identical effect:

    INSERT INTO table (a,b,c) VALUES (1,2,3)
    ON DUPLICATE KEY UPDATE c=c+1;""

    Re: Sql insert statement

    Ok i have found some of the problem and ran into another. i needed to be using native sql not protable, and this is what my connect string looks like
    Code:
    dim sqlInsertStatement as c 
sqlInsertStatement = <<%txt%
INSERT INTO contact  (idContact, fname, lname, phone, fax) VALUES (:idContact, :fname, :lname, :phone, :fax)
	ON DUPLICATE KEY UPDATE idContact=:idContact
    the :idcontact is a value stored in a variable and i can't get it to fire correctly it's not inserting the record or updateing can anyone tell me where i'm going wrong.

      Re: Sql insert statement

      I haven't used the DUPLICATE KEY UPDATE syntax but you haven't described what you want to happen if the duplicate key exists. I believe you need to code the UDPATE clause, e.g.,

      Code:
      sqlInsertStatement = <<%txt%
INSERT INTO contact  (idContact, fname, lname, phone, fax) VALUES (:idContact, :fname, :lname, :phone, :fax)
	ON DUPLICATE KEY UPDATE 
set fname=:fname, lname=:lname, phone=:phone, fax=:fax
      The only difference between the UPDATE statement here and a regular UPDATE is that a WHERE clause
      is not needed, since the record is selected by the presence of a duplicate idContact.

      An alternative syntax is MySQL's REPLACE INTO, which is simpler, and is
      Code:
       
REPLACE INTO contact  (idContact, fname, lname, phone, fax) VALUES (:idContact, :fname, :lname, :phone, :fax)
      REPLACE INTO does an INSERT INTO if the key doesn't exist or a DELETE FROM and INSERT INTO if it does. I don't know how REPLACE INTO works with autoincrement columns. If you don't have any autoincrement columns and are always inserting/replacing the entire record, then REPLACE INTO may be what you want. Otherwise, ON DUPLICATE KEY UPDATE is probably safer.

        Re: Sql insert statement

        well peter still can't make it do what i want. I'm trying to avoid making a set and forms based on the sets only need certain data open and don't want the whole database opening for 1 record. records start on the first table lead, then once you get to the next step i have a dialog popup and load variables from the xdialog. Then insert record on contact table and if record exsists then to update everything but the contactid.

          Re: Sql insert statement

          My mistake, the syntax for duplicate key update does not accept "set". Should be

          Code:
          sqlInsertStatement = <<%txt%
INSERT INTO contact  
(idContact, fname, lname, phone, fax) 
VALUES 
(:idContact, :fname, :lname, :phone, :fax)
ON DUPLICATE KEY UPDATE 
fname=:fname, lname=:lname, phone=:phone, fax=:fax

              Re: Sql insert statement

              You're moving back and forth among global variables, local variables, and shared (session) variables. There's no need for your script to use anything other than local variables.

              Try this:
              Code:
              'Create an XDialog dialog box to prompt for parameters.
DIM  vfname as C
DIM  vlastname as C
DIM  vphone as C
DIM  vfax as C
DIM  varC_result as C
ok_button_label = "&OK"
cancel_button_label = "&Cancel"
varC_result = ui_dlg_box("Contact Info",<<%dlg%
{region}
{Region}
;
{Endregion};
{Region}
First Name:| [.40vfname];
Last Name:| [.40vlastname];
Phone:| [.40vphone];
Fax:| [.40vfax];

                  Re: Sql insert statement

                  You have a typo that I copied inadvertently:

                  dim sqlInsertStatement as c <<%txt%
                  sqlInsertStatement = INSERT INTO contact (idContact, fname, lname, phone, fax)
                  VALUES (:idContact, :fname, :lname, :phone, :fax)
                  ON DUPLICATE KEY UPDATE fname=:fname, lname=:lname, phone=:phone, fax=:fax
                  %txt%


                  It needs to be

                  dim sqlInsertStatement as c = <<%txt%
                  sqlInsertStatement = INSERT INTO contact (idContact, fname, lname, phone, fax)
                  VALUES (:idContact, :fname, :lname, :phone, :fax)
                  ON DUPLICATE KEY UPDATE fname=:fname, lname=:lname, phone=:phone, fax=:fax
                  %txt%

                    Re: Sql insert statement

                    Sorry it took me so long to get back to this but i still keep comming up with an error that the sql string is empty, somewhere my variables are losing their value and if i change it i get bad syntax on the sql statement. So it's half way there if i can get away from the empty sting.

                      There were actually two typos and I only corrected one. This should work:

                      dim sqlInsertStatement as c=<<%txt%
                      INSERT INTO contact
                      (idContact, fname, lname, phone, fax)
                      VALUES
                      (:idContact, :fname, :lname, hone, :fax)
                      ON DUPLICATE KEY UPDATE
                      fname=:fname, lname=:lname, phone=hone, fax=:fax

                        You still have some typo's but i caught them and it works Thank you peter for your help.
