<p>To restore the database from the command line, first confirm the backup file type and use the appropriate tool. 1. Ensure that the backup file is correct: If the .sql file exported by Navicat can be used directly; if it is a compressed file, you need to decompress it first. 2. Select tools according to database type: MySQL/MariaDB uses mysql -u [username] -p [database_name] </p> <p> Restoring a database from the command line using Navicat isn't something you do directly <em>inside</em> Navicat itself, since Navicat is primarily a GUI tool. However, Navicat works well with command-line tools like <code>mysqldump</code> or <code>psql</code> , depending on your database type. If you're looking to restore a backup using the command line and possibly triggered by or in coordination with Navicat, here's how to approach it.</p> <hr> <h3 id="Make-Sure-You-Have-the-Right-Backup-File"> Make Sure You Have the Right Backup File</h3> <p> Before jumping into commands, confirm what kind of file you're working with:</p> <ul> <li> <strong>SQL dump files</strong> (common for MySQL, MariaDB, PostgreSQL)</li> <li> <strong>Binary backups</strong> (more advanced, usually not restored via simple CLI commands)</li> <li> <strong>Compressed files</strong> (.sql.gz or similar — need decompression first)</li> </ul> <p> If you created the backup using Navicat's export feature, it's likely an <code>.sql</code> file. This is the most straightforward to restore via command line.</p> <blockquote><p> If the backup was compressed, use <code>gunzip</code> or extract it first before proceeding.</p></blockquote> <hr> <h3 id="Use-the-Correct-Command-Line-Tool"> Use the Correct Command-Line Tool</h3> <p> Depending on your database type, you'll use different tools:</p> <h4 id="For-MySQL-MariaDB"> For MySQL / MariaDB:</h4><pre class='brush:php;toolbar:false;'> mysql -u [username] -p [database_name] < backup_file.sql</pre><ul><li> Replace <code>[username]</code> with your actual MySQL user.</li><li> <code>[database_name]</code> should already exist unless you're importing to a new DB.</li><li> The <code><</code> symbol feeds the SQL file into the MySQL client.</li></ul><h4 id="For-PostgreSQL"> For PostgreSQL:</h4><pre class='brush:php;toolbar:false;'> psql -U [username] -d [database_name] -f backup_file.sql</pre><p> You might also be prompted for a password unless you're using a <code>.pgpass</code> file or local trust settings.</p> <blockquote><p> If you're restoring a dump made with <code>pg_dump</code> , this method works fine. Just make sure the target database exists unless the dump includes the CREATE DATABASE statement.</p></blockquote> <hr> <h3 id="Handle-Common-Issues-During-Restore"> Handle Common Issues During Restore</h3> <p> Sometimes things don't go smoothly. Here are common gotchas:</p> <ul> <li> <strong>Database doesn't exist yet:</strong> Create it first using <code>CREATE DATABASE [name];</code> via the CLI or Navicat.</li> <li> <strong>User permissions:</strong> Ensure the user has access to the target database.</li> <li> <strong>File path issues:</strong> Double-check that the terminal is in the right directory or provide the full path to the <code>.sql</code> file.</li> <li> <strong>Encoding mismatches:</strong> If you see weird characters, try specifying the charset with <code>--default-character-set=utf8mb4</code> (MySQL) or <code>\set ENCODING 'UTF8'</code> in psql.</li> </ul> <blockquote><p> If the restore process seems stuck or fails silently, run it in verbose mode if possible, or break the file into smaller chunks using text editors or scripts.</p></blockquote> <hr> <h3 id="Optional-Trigger-or-Coordinate-with-Navicat"> Optional: Trigger or Coordinate with Navicat</h3> <p> While Navicat doesn't have a built-in command-line interface, you can coordinate between Navicat and the terminal:</p> <ul> <li> Use Navicat to create the backup (export as SQL dump).</li> <li> Then switch to the terminal to restore it faster or on a remote server.</li> <li> You can also view logs or check connection details inside Navicat to ensure the CLI command uses the correct credentials.</li> </ul> <p> This hybrid workflow is especially handy when dealing with large databases or scripting automation.</p> <hr> <p> Basically that's it. As long as you confirm the file type and use the correct commands, the recovery process is actually not complicated, but it is easy to ignore the details of permissions or encoding settings.</p>
