cannot access db tables

[andrewkl]

I upgraded to version 3.5.4 (from version 3.4.5)

After sucessfully connecting to the db, i get the following error:

DBCException: SQL Error [1064] [42000]: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<...>' at line 1

when i click on "Tables" [ General -> Connections -> <my_connection> -> Databases -> <my_db> -> Tables ]

Everything worked fine with version 3.4.5; Anything higher than 3.4.5 produces the above error.

Why am i getting this error?

Thanks

Most likely you have bad MariaDB driver (3.0 beta?).
- Go to MariaDB driver editor
- Click Download/Update
- In driver artifact version choose some stable version (for instance 3.2.0).
- Click "Download"
- Reconnect

I'm using MySQL and there is no change to the way MySQL was configured.

The problem goes away if i downgrade back to v3.4.5 of DBeaver. Problem reappears when i upgrade. This is reproducible each and everytime for each upgrade/downgrade of DBeaver.

Main difference between 3.4.x and 3.5.x is in the drivers management.
After 3.5 DBeaver gets most recent drivers from Maven (while 3.4 has preconfigured MySQL jConnector 5.1.27).
So I still think that driver is the main reason.
Could you say what exact version of MySQL driver do you have?
Could you post a complete stacktrace of the error (you can get it in "Error Log" view)?

I downloaded mysql-connector-java-5.1.37-bin.jar from http://dev.mysql.com/downloads/connector/j/

From the cmd.exe (Windows 7) console, i ran the following 2 commands:

set CLASSPATH=C:\the\full\path\to\mysql-connector-java-5.1.37-bin.jar
dbeaver.exe

This is the cut-and-paste of the error from the logs produced by dbeaver v3.5.4 :

It looks like DBeaver 3.5.4 is only compatible with MySQL jConnector 5.1.28 and earlier.

I went ahead and downloaded MySQL jConnector 5.1.28 and DBeaver 3.5.4 is able to access the db tables.

[Serge]

That's pretty weird.

Could you try one more thing:
- Open Preferences->Common-Query Manager
- Turn on all checkboxes in Query Types and Object Types
- Open Query Manager view (main menu Window)
- Try to expand node "Tables"

Query manager will print metadata query which DBeaver will try to execute to read the table list.
Post this query here.

Thanks

I did the following:

- Open Preferences->Common-Query Manager
- Turn on all checkboxes in Query Types and Object Types
- Open Query Manager view (main menu Window)
- Try to expand node "Tables"

When i tried to to expand "Tables", this pops up:

DBCException: SQL Error [1064] [42000]: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<...> at line 1
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<...>' at line 1

I don't see anything else. Where else should i look?

Thanks

[Serge]

In Query Manager you can see queries which DBeaver executes to read metadata. Something like this:

qm-connect.png (21.63 KiB) Viewed 557422 times

Do you see it? I need to see the query DBeaver executes when you expand tables.

Hi

I upgraded to the latest version (3.5.6) of DBeaver and used the latest MySQL jConnector (5.1.38) .

No more issues accessing the db tables.

Thanks for all the help.

Thanks
