问题 I have a query that does multiple joins on several tables and uses a covering index. It seems to run a lot faster when executed directly from the mysql cli instead of from mysql workbench. mysql > some query ... 250 rows in set (0.05 sec) from mysql workbench it takes about ~0.200 sec duration / 0.100 sec fetch Is there a reason beyond latency, authentication and transfer of data why it would be orders of magnitude faster on the console? Does a three-way tcp handshake occur each time a query

问题 I managed to download the MySQL DMG archive to my OS (mac OS X). It works if I use the command line. Now, I'm trying to install MySQL Workbench. I've created MySQL Connection but once I'm testing the host machine settings, I get: Checking command 'ps xa | grep "/usr/local/mysql.*/bin/[m]ysqld"' Server detected as running Check if /etc/my.cnf can be accessed Operation failed: File /etc/my.cnf doesn't exist I'm trying to find the file my.cnf and I get: Didis-MacBook:~ Didi$ find . -type f -name

问题 I am using MySQLWorkbench 5.2, the newest version as far as I know, but I simply cannot change the font. It is very inconvenient, because the default font is very small and harsh on the eyes. The appearance tab has options for changing the font, but no change can actually be made there, as the field cannot actually be edited. Does anyone know of a way around this? It seems to be a common bug, but I can't find a fix anywhere. 回答1: In the Edit > Preferences... > Appearance > Fonts section of

问题 I'm trying to save a query result of about 1,000,000 records in MySQL Workbench. When I run the SELECT, only 1000 records shows up (MySQL Workbench's default limit). I know I can change the limit, or remove the limit, but I don't want 1,000,000 records to be loaded into the result panel (which might crash my computer?), but I do want to save the results to a file. Does MySQL Workbench let you save the results of a query directly to a file? Or save the whole result set instead of the 1,000?

问题 Is it possible for me to connect to a MSSQL database server with MySQL Workbench? 回答1: You cannot use MySQL Workbench as a Microsoft SQL Server client. But technically speaking, yes, you can connect to a Microsoft SQL Server database using ODBC if you are using the database migration wizard.

问题 yesterday I updated my Workbench to the latest version available, the 6.3.6 build 511 CE on Windows 10. Now I'm trying to make a dump of a remote database via the "Data Export" feature, which has always worked. But, as soon as I click the "Start Export" button, I get this error: Unhandled exception: Error querying security information: Error executing 'SELECT * FROM mysql.user WHERE user = ' [username] ' and Host = ' [host] ' ORDER BY User, Host' SELECT command denied to user ' [username] '@'

问题 I keep finding that MySQL Workbench shows query results as BLOB . e.g: SELECT INET_NTOA(167773449) --> BLOB If I select to 'view value' I can determine the text value is '10.0.5.9' but it's pretty irritating when I SELECT multiple rows and want to glance at the contents. Is there a way around this or is it a limitation of the tool? 回答1: Background: This problem occurs when the binary string values (BINARY/VARBINARY type) are returned in the results. The binary strings contain the zero bytes
