The format of the file used for import should be SQL. This can be changed by clicking on the drop-down arrow for Format. However, to keep things simple, we are going to be using the default format of .SQL. Click on Go in order to start the import.
This completes our tutorial on importing tables into a database. Depending on the size of the table, it may take some time for the import to complete. When the import completes you will be able to look at the tables of the database and see the table that you have imported.
Import Options and Settings
When importing a table in phpMyAdmin, you’ll find several options that help customize the process beyond just using the default SQL format.
SQL (.sql) is the most commonly used format because it includes both the table structure and the data. However, phpMyAdmin also supports formats like CSV (.csv) for data-only imports, as well as XML and compressed files like .zip or .tar.gz.
Format: Choosing the correct format is important for a successful import and should match the type of file you’re working with.
Character set: Another key setting is the character set. This determines how data is encoded, which affects how special characters and non-English text are handled. UTF-8 is recommended because it supports a wide range of characters and works well with most databases.
Foreign key checks and partial imports: phpMyAdmin also offers settings such as foreign key checks and partial imports. Foreign key checks help maintain relationships between tables. Disabling them temporarily can speed up large imports or avoid issues when related data isn’t imported in the right order. Just be sure to re-enable them afterward to preserve data integrity.
Partial import settings control how phpMyAdmin responds to errors. You can choose to continue on error—logging failed rows but completing the import for valid data—or rollback on error, which cancels the entire import if any problem occurs.
“Continue on error” works well for large, non-critical data loads. In contrast, “rollback on error” is better for critical imports where data consistency is essential.
CSV Import Guide
Importing CSV files requires some specific configurations to ensure data integrity:
- Delimiter Configuration: Specify the character that separates your fields in the CSV file, usually a comma (,) but sometimes semicolons (;) or tabs.
- Handling Headers: Indicate whether your CSV file includes a header row with column names. If so, make sure to select the option so phpMyAdmin treats the first row correctly.
- Excel Conversion: If your data is originally in Excel, export it as a CSV file before importing. Ensure the CSV file formatting matches the structure of the target table, including the correct number of columns and data types.
Troubleshooting Common Import Issues
Database imports can be tricky, but knowing how to tackle common errors makes the process smoother. Here are some common import issues and how to troubleshoot them:
File Size Limitations and Workarounds
phpMyAdmin often has an upload limit (commonly 50MB). For larger files, consider splitting the SQL file into smaller parts or use SSH with command-line tools like mysql for importing.
Column Count Mismatch Errors
This occurs if the number of columns in your CSV file doesn’t match the table’s columns. Double-check your CSV file and the target table structure to ensure alignment before importing.
Character Set/Collation Problems
If you notice strange characters or encoding issues after import, revisit the character set selection and ensure it matches the encoding of your source file and the database’s collation settings.
Timeout or “MySQL Server Has Gone Away” Errors
These errors happen when the import process takes too long or the server disconnects. Increasing server settings like max_allowed_packet or importing via command line instead of phpMyAdmin can resolve these issues.
SQL Syntax Errors
If your import fails with syntax errors, review the SQL file for mistakes such as missing semicolons, incorrect commands, or unsupported features. Cleaning up the SQL file or exporting again from the source often fixes these issues.
