由 自闭症网瘾萝莉.ら 提交于 2020-01-02 10:59:33
问题 I have a script that i am writing to move certain fields to a new db like $results = mysql_query ( "SELECT body, title FROM $source_db.Post" ); while ($row = mysql_fetch_array($results)) { if(mysql_num_rows($users_result) > 0){ $insert = "INSERT INTO wp_posts (`body`,`title`) VALUES ('{$row['body']}', '{$row['row']}')"; mysql_query($insert); } } but as you can see the query will break everytime due to the single and double quotes, is there a solution to this problem like herdok or something

由 半腔热情 提交于 2020-01-01 09:42:20
问题 The database "db" is backuped in backup.sql. Is there a way to restore database from script with different from "db" name? thank you in advance! 回答1: Sure, when you import it you do this right: mysql -uuser -ppassword databasename < mydump.sql You can put anything you want where I wrote databasename - as long as that database actually exists :) 回答2: If the name of the database is include the SQL file, I didn't find any other way than modify the SQL file.

Skip or ignore definers in Mysqldump

由 情到浓时终转凉″ 提交于 2020-01-01 09:37:29
问题 I was wondering if I can prevent mysqldump inserting this commands /*!50017 DEFINER=`root`@`localhost`*/ Or if I have to do it afterwards with sed, for example Thanks! 回答1: This issue has been around since 2006 with no sign of ever being fixed. I have, however, piped it through grep (linux only) to trim out the definer lines before writing the dump file: mysqldump -u dbuser -p dbname | grep -v 'SQL SECURITY DEFINER' > dump.sql A bit of a mouthful (or keyboardful?) but I think it's the only

问题 I have got two dedicated servers with root access. Both are running Linux. I want to import database from Server1 to Server2. I have already created an empty database on Server2. I want to know Linux command through which I can import database directly? Is there such a feature? Can I use mysqldump? I want to avoid first taking database backup on server1, then moving that file to server2, and then importing that file. Can import be done directly using some command? Thanks 回答1: If you want to

How to Export & Import Existing User (with its Privileges!)

由 回眸只為那壹抹淺笑 提交于 2019-12-31 17:39:35
问题 I have an existing MySQL instance (test), containing 2 databases and a few users each having different access privileges to each database. I now need to duplicate one of the databases (into production) and the users associated with it. Duplicating the database was easy: Export: mysqldump --no-data --tables -u root -p secondb >> secondb_schema.sql Import: mysql -u root -p -h localhost secondb < secondb_schema.sql I didn't find, however, a straightforward way to export and import users , from

How do I use mysqldump to export only the CREATE TABLE commands?

由 蹲街弑〆低调 提交于 2019-12-31 08:42:54
问题 I'm trying to use mysqldump to export only the DB schema -- no data, no additional SQL comments, just the CREATE TABLE commands. Here's what I've got so far: mysqldump -h localhost -u root -p --no-data --compact some_db It almost achieves what I want, but I'd like to eliminate the "character set" lines (those like the first 3 lines in the example output below). Is there a mysqldump option to do that? /*!40101 SET character_set_client = @saved_cs_client */; /*!40101 SET @saved_cs_client = @

InnoDB tables exist in MySQL but says they do not exist after copying database to new server

问题 I used mysqldump to export my database and then I imported it into MySQL on my other server. I can now see all my tables if I do "show tables" but I can't actually select from or describe any of them. ERROR 1146 (42S02): Table 'mydatabase.user' doesn't exist All of my tables are InnoDB. I saw one issue people had where they were using old_passwords, so I explicitly set that to 0 in my.cnf and I made sure all of the passwords in the mysql table were 41 hexadecimal digits as they should be for
