WaveLength posted 11 years ago. Thank you for your advice. I followed your instructions, but after "select column name in current table" Heidi asks me to save the table, and when doing so, I get an error message I can't tell exactly what the error message is because the font is small, and I cannot select it with my mouse to paste it in a larger font.

Is there a bug in the software? Do you have any idea what the problem might be? The font is small? That's a normal error dialog, man. Okay, I didn't know you could do that. Hm, looks like you did not follow the above recipe.

To clarify, here are the steps I followed: 1. I clicked on a table in the left pane, then selected the Table tab and the Foreign Keys tab. I clicked the green Add button. I clicked to the left of column 6, which contains integers only. This turns the column blue a horizontal blue bar.

I clicked the table containing the foreign key, and a Save Modified Table requester box appears. I clicked Yes in the requester to save, and I get the error. The modified version of the table is not saved. But if I do it this way it works. It references to the primary key of the same table. There is a unique way of doing things with the appropriate receipe. As said quite some times before, I could not reproduce that issue.

And I still believe you did something wrong, or maybe are using some setting which you forgot or similar. Sometime it works, sometime it does not work. If it was not configured properly it would never work. I never seen this before. Just disapointed. I'm working on a project and I'll have to start all over again.

Every tables are there with the FK, every one of them. I just tested your both scripts from above here, and both work, including the one which you say did not work. I only had to add some missing semicolons to the end of queries.

Are you sure you added these on your side as well? And also, you should probably send queries one by one, although both should work, but just in case:. It worked this manner. I was now trying to figure out, why it was consistent. I think you gave me an appropriate answer. Well Patsy. One more issue to solve. How comme I cannot create and save FK directly in the database. It appears properly, but I cannot save it.

First make sure both the child referencing table the one for which the FOREIGN KEY constraint is being defined and the parent referenced table the other table, whose columns are being referenced by the child table use InnoDB storage engine. Why are there so many different storage engine? I globaly modified all databases I have created to InnoDB storage engine. I've myself been using this tool since Small application but really efficient. It can be experimented by downloading a copy on the Silverrun Grandite's site.

This is the type of view I can create with Sql Server. I need the adresse number including the street name which is " adresse. The picture shows the result as it is, but it does not concatenate as SQL server does. What am I doing wrong? Ads were blocked - no problem. But keep in mind that developing HeidiSQL, user support and hosting takes time and money.

You may want to send a donation instead. New topic Register Log in. Hi I create a foreign key. But I cannot save it. I seems to save but it does not. Anyone met this situation before. Thanks Fern 2 attachment s :. Or is it because the foreign key was already created in the initial script? Hi I installed the May I ask you to update once again, now that I just released v I also guess you got some error message when trying to add foreign keys, right?

Be sure the yellow warning sign is pressed if you want to see errors:. Which server and server version are we talking about? Hi I did exit and restart many times. Could we talk in real time.

Ok, in the end I can see all foreign keys were created. I had to create the table soumission as you did not post that one. This is how it ought to appear. If I create the foreign keys in Heidi, they are not saved when I save the table. But I don't get any error message. The Stop Errors in batch mode is depressed, but as you see in the previous line there are no errors.

Nothing is written in the database, except the table itself and the indexes, but the indexe columns are not referenced to original table. I have the impression we are nearly real time here. Not sure how Zoom would make it quicker. Also, if we solve it here, we could help others having the same problem, later. I'm a model manager. It generates your model in any of those databases version. But still, it seems Heidi does not create the FK even if we try to create them in the tool.

I will try again on a MariaDB But I have no hope that suddenly let's me reproduce this issue. While I think you were using "the tool" in HeidiSQL to create the foreign keys and I guess you mean the visual table designer , that also does not matter. Foreign keys should be there afterwards. It works that way too. This is your example but in the creation of another table. I realized that the FK references to different columns. See this does not work. But if I do it this way it works.

It references to the primary key of the same table. There is a unique way of doing things with the appropriate receipe. As said quite some times before, I could not reproduce that issue.
