I am using the MySQL for Excel add-in. I have been using this for months to highlight a set of data and load it into my database.
I added a new table last week, and was successfully loading data into it using the same method. It stopped working. When I attempt to Append data, I get an error dialogue box that says "Cannot Find Column 30"...which happens to be the number (and therefore) last column in my table.
Some more information:
- If I highlight this same set of data and try to write it to another table, it will allow me to (even though I don't confirm and do it). I get past the error dialogue box to the Mapping dialogue box.
- I tried writing data from the previous table to this new problem table. I got the same error dialogue box.
This tells me that the problem is not with the data set. It is with the table.
I then deleted the table, all the connections and redid it from scratch. Still the same problem.
Where is this failing? Thank you.
ya even i had the same problem, even i tried the same way u did, like deleted the table recreated everything, it did not work, finally i tried to append some random table and went to "Advanced Options" at the bottom of the append pop up
in this u will see some "Stored Column mappings" and some mappings in it, now delete all of them and hit "Accept" now u can append the table
it will work
I know this is super old but I have a solution because it just happened to me.
Try append on different table. When box pops up click 'Advanced Options'
Then under column mapping uncheck both:
(Automatically store the column mapping for the given table) AND
(Reload stored column mapping for the select table automatically)
Then goto the Stored mappings tab and delete all the stored mappings
Click Accept and then rejoice you are free of that error for life.

If Excel does not show you the "Stored Column mappings" then connect to a MySQL table not used before in Excel, then retry the Append, the mapping will be shown. Then you can follow the answer provided by user3611272.
Problem will be resolved by doing below steps:
Select any table from Table other than your target table.
Click on Append Data
Press "Advanced Options"
Select tab "Stored Mappings"
Delete your target table mapping and Accept.
it will solve the issue.

I am the superuser of a particular database schema. Therefore I have all privileges on the tables in this schema, including ALTER DELETE UPDATE and INSERT.
I am administrating this database using the GUI MySQL Workbench 6.3. I used to select rows and to obtain a read-only result grid, which was convenient because it prevented me from accidentally editing data in my table.
This was indicated by a 'read only' flag in the bottom right corner of the result grid (see below).
However, I did not change anything in the structure of the table, and now when I select rows I am able to edit data and the 'read only' flag has disappeared.
I find it a bit unsecure because it would mean I could accidentally edit data in the table by mistyping.
How could I revert to a read-only result display?
The rules that allow editing a result set are very strict. The select query must be a plain one - no aggregate functions, no joins, no unions. There must be a primary key which is used to address the records to be changed.
Update: it wasn't necessary to worry about accidentally editing records in the table while not being in read-only mode.
Indeed, if you change a record in the table (in the screenshot below, I changed a year from 2010 to 2020), for this change to be actually committed in the database, you would need to click the "apply" button in the bottom right corner.
Moreover, upon closing the tab, you are asked whether or not you want to save changes. Consequently, if you accidentally edited a record, you just have to click "Don't save" upon closing the tab.
I've successfully connected LibreOffice Base with MySQL data base server. I've tested if I modify my table from host (free hosting service on internet) then the changes are reflected when refreshing the table object in LO Base.
But my question is, can I modify DB table directly from LO Base? I guess that it's possible using sql queries from LO Base, but how? Please give me some insights or tutorials. Thanks.
The normal way to alter a table:
Tools -> SQL
Enter an ALTER TABLE command and press Execute button.
A way that works, even though it complains that no result set is returned:
Create a query in SQL view.
Enter ALTER TABLE command.
Click button in toolbar to mark it as Run SQL command directly. Or Edit -> Run SQL command directly.
Close the query and double-click to run it.
My guess is it could be done with a macro as well, similar to https://forum.openoffice.org/en/forum/viewtopic.php?f=5&t=75763 but using ALTER TABLE.
For more ideas see https://forum.openoffice.org/en/forum/viewtopic.php?f=61&t=37687.
EDIT:
Inserting new row data in a form is easier than altering the table. First, make sure this works:
Double-click on your table under Tables.
Insert -> Record, or enter data in the last new row.
If Insert -> Record is disabled, then you need to set up the table for editing. Make sure that your connection to the database allows editing. Also the table must have a primary key.
Once you can insert records in Table view, it's time to create the form:
Under Forms, Use Wizard to Create Form.
Select your table and press >> to include all fields.
Click Finish.
Now you should be able to open the form and enter data into the final new row.

I have 2 table, one is local named 'Client' and other is a linked table to MySQL DB in my web-server named 'ClientSql'.
When I insert data into the table Client, I want it to be insert into clientSql too. I try it with data macro (after insert), but it shows me an error saying
It's not possible in linked tables.
I have tried to create an append query successfully, and it works, but it just works if I execute it manually. My question is:
Is it possible to call it from a data macro? if is possible, can you show me how? If not, can you point me to a solution?
I'm not sure why you should be able to do it manually, but not via a macro. According to this link
http://dev.mysql.com/doc/connector-odbc/en/connector-odbc-examples-tools-with-access-linked-tables.html
you should be able to do it either way.
Another thought is to eliminate the local access client table and have the access program update the mySql table directly. However, if another program is accessing the client table at the same time, this could become tricky due to multi-user and locking situations.
The error message "The search key was not found in any record" was appearing on one record of a table in Access 2010.
I first noticed this when accessing that record via an update query, but later found that I also got the same error when trying to delete the record.
What causes this, and how can it be resolved?
It was just a database corruption, but I was misled by it only affecting one record. A Compact and Repair sorted it immediately.
Sometimes this happens because the field name contains a leading space, ensure your field names are trimmed before and after.
Example: It happened to me when I was trying to import an Excel sheet contains the first row as field names, two of the field names was " Latitude" and " Longitude". From this post I knew the problem's cause, so I changed them to "Latitude" and "Longitude" (without the leading space), and the problem was solved.
I know this is an old post, but i just ran into this issue and none of the other answers seemed to solve or address my scenario.
Using a copy of the dbase, i had to continue to delete tables until the error message ceased.
The table at fault was a hidden, system table with the name MSysComplexColumns. I deleted it, closed the dbase and the table was auto-created upon re-opening the dbase. That completed solved it with no side effects.
In my case, this error message was triggered by the size of my Access file. When its size exceeded 2,000,000 KB, the message popped up when I was importing another document. As long as I reduced its size, the message stopped and the import process finished successfully.
Also check the database version. I was having the problem with VBA CreateDatabase(sTempDBName, dbLangGeneral) in Access 2010 where I was using a 2003 database trying to link a table in a 2010 database. When I manually tried the link I got a message about no support for linking to a later version. Creating the temp database I was trying to link to using the option dbVersion40 "CreateDatabase(sTempDBName, dbLangGeneral, dbVersion40)" cured it.
It is very strange what is happening, I have never seen this before and I am pretty familiar with mysql.
When searching a table using the phpMyAdmin table search feature, the result is empty no matter what I put. For example, searching 77 in the ID column returns empty result. However if I run an SQL query also in phpMyAdmin, and then there is the result. For example, select * from table1 where id = ‘77’;
What is even more strange is this only happens on one table, all other tables the search feature is working fine.
I tried repairing the table but empty result still occurs.
I couldn’t find this happening anywhere to any one online…..
Also restarted sql server.
Are you using cPanel - if yes I just described how to fix the problem on cPanel forums:
http://forums.cpanel.net/f5/unable-use-phpmyadmin-search-users-table-313381.html
If your table has a large number of fields an update via the phpMyAdmin interface can exceed the value for the PHP setting 'max_input_vars'. When this happens some of the internal form fields that phpMyAdmin is expecting to receive on the page your update is being posted to are truncated which causes phpMyAdmin to fail, unfortunately silently, and the page redirects with no warnings back to the blank search form. The default for 'max_input_vars' is 1000. I upped mine in my php.ini file to 5000 with no negative side affects and it solved this problem for me.
The setting 'max_input_vars' has a mode of PHP_INI_PERDIR so if you don't have access to your php.ini file then you may be able to set it in an .htaccess file, your httpd.conf file or your .user.ini (since PHP 5.3) file if you have one. I'm not sure exactly what code you would need for an htaccess file but the PHP code to do it is below.
ini_set('max_input_vars', '5000');
Hopefully that should get you started in the right direction.
Very easy. Go to the table and expose max number of rows as much as is showed in the dropdown. Then you are able to search per big pages. It doesnt fetch text through all the table. It plays only with a page of the table.
