Mysql Error 1054 Unknown Column In Where Clause
for the report, I'll have a look at this over the weekend. Philio was assigned Jun 3, 2011 jimrobinson commented Aug 17, 2011 I've found myself having to wrap any columns that may potentially contain NULLs with a COALESCE(), to work around this problem. Collaborator edwardrf commented Aug 31, 2011 Hi dtjm, Philio, After debugging into the code dtjm provided, I realize it is a 2 part problem, the first part is very easy to solve, but the 2nd mysql error 1049 unknown database part is really difficult, which may touch some fundamental stuff of the project to solve. First problem is actuallly in handler.go line 231, after the binary handler determined the next value is nil, though assigned nil to field, but field is never added to the row slice. So you need to add an append to the row: "row = append(row, field)" if nbm[posByte]&(1< Thomas Rupprecht Email Updates: Status: Can't repeat Impact on me: None Category:MySQL Server: Command-line Clients Severity:S2 (Serious) Version:5.1.57, 5.5.24 OS:Microsoft Windows (win 7 64 bit Professional) Assigned to: Tags: Lost connection, mysql error 1273 unknown collation network problem View Add Comment Files Developer Edit Submission View Progress Log Contributions [16 Jul 2011 14:38] error 2005 (hy000) unknown mysql server Thomas Rupprecht Description: I have installed MySQL 5.1.57 64 bit version on Windows 7 64 bit Professional-Version. When I try to read a large set of rows with https://github.com/Philio/GoMySQL/issues/52 a client (>15000 rows) I already get the error "Lost connection to server". This happens in mysql console client, mysqldump, workbench, query-browser, jdbc-driver when connection via TCP/IP from loacal or remote client. I searched the web for that problem. I found a lot of network problems and I tried all the suggestes solutions. Everytime the same result. https://bugs.mysql.com/bug.php?id=61886 There is no difference on the database engine used (same result on InnoDB and MyISAM). During my research I figured that the debug version of the server (5.1.57) started with the same configuration file runs fine - slower but it doesn't crash. Huge sets of rows (>100000) can be read. It looks that there might be a difference in compiling/otpmizing/libraries used for the production and the debug version. I made a test with the 32 bit version 5.1.57 on Windows 7 64 bit Professional. This version also crashs when try to read a large dataset. Using this version on XP 32 bit and Vista 32 it works fine and doesn't crash. Using other database, ftp-server on that system run fine. Megabyte of data are transfered over the network adapter without any problem. How to repeat: Windows 7 64 bit German MySQL 5.1.57 64 bit Database with a tables which contaisn 500.000 rows (a few columns filled with random data) MyISAM or InnoDB.
