Import and export

导入

To import data, go to the “Import” tab in phpMyAdmin. To import data into a specific database or table, open the database or table before going to the “Import” tab.

In addition to the standard Import and Export tab, you can also import an SQL file directly by dragging and dropping it from your local file manager to the phpMyAdmin interface in your web browser.

If you are having troubles importing big files, please consult 1.16 I cannot upload big dump files (memory, HTTP or timeout problems)..

You can import using following methods:

Form based upload

Can be used with any supported format, also (b|g)zipped files, e.g., mydump.sql.gz .

Form based SQL Query

Can be used with valid SQL dumps.

Using upload directory

You can specify an upload directory on your web server where phpMyAdmin is installed, after uploading your file into this directory you can select this file in the import dialog of phpMyAdmin, see $cfg['UploadDir'].

phpMyAdmin can import from several various commonly used formats.

CSV

Comma separated values format which is often used by spreadsheets or various other programs for export/import.

注解

When importing data into a table from a CSV file where the table has an ‘auto_increment’ field, make the ‘auto_increment’ value for each record in the CSV field to be ‘0’ (zero). This allows the ‘auto_increment’ field to populate correctly.

It is now possible to import a CSV file at the server or database level. Instead of having to create a table to import the CSV file into, a best-fit structure will be determined for you and the data imported into it, instead. All other features, requirements, and limitations are as before.

CSV 使用 LOAD DATA

Similar to CSV, only using the internal MySQL parser and not the phpMyAdmin one.

ESRI 图形文件

The ESRI shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by Esri as a (mostly) open specification for data interoperability among Esri and other software products.

MediaWiki

MediaWiki files, which can be exported by phpMyAdmin (version 4.0 or later), can now also be imported. This is the format used by Wikipedia to display tables.

Open Document Spreadsheet (ODS)

OpenDocument workbooks containing one or more spreadsheets can now be directly imported.

When importing an ODS spreadsheet, the spreadsheet must be named in a specific way in order to make the import as simple as possible.

数据表名

During import, phpMyAdmin uses the sheet name as the table name; you should rename the sheet in your spreadsheet program in order to match your existing table name (or the table you wish to create, though this is less of a concern since you could quickly rename the new table from the Operations tab).

字段名

You should also make the first row of your spreadsheet a header with the names of the columns (this can be accomplished by inserting a new row at the top of your spreadsheet). When on the Import screen, select the checkbox for “The first line of the file contains the table column names;” this way your newly imported data will go to the proper columns.

注解

Formulas and calculations will NOT be evaluated, rather, their value from the most recent save will be loaded. Please ensure that all values in the spreadsheet are as needed before importing it.

SQL

SQL can be used to make any manipulation on data, it is also useful for restoring backed up data.

XML

XML files exported by phpMyAdmin (version 3.3.0 or later) can now be imported. Structures (databases, tables, views, triggers, etc.) and/or data will be created depending on the contents of the file.

The supported xml schemas are not yet documented in this wiki.

导出

phpMyAdmin can export into text files (even compressed) on your local disk (or a special the webserver $cfg['SaveDir'] folder) in various commonly used formats:

CodeGen

NHibernate file format. Planned versions: Java, Hibernate, PHP PDO, JSON, etc. So the preliminary name is codegen.

CSV

Comma separated values format which is often used by spreadsheets or various other programs for export/import.

CSV for Microsoft Excel

This is just preconfigured version of CSV export which can be imported into most English versions of Microsoft Excel. Some localised versions (like “Danish”) are expecting “;” instead of “,” as field separator.

微软 Word 2000

If you’re using Microsoft Word 2000 or newer (or compatible such as OpenOffice.org), you can use this export.

JSON

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and it is easy for machines to parse and generate.

在 4.7.0 版更改: The generated JSON structure has been changed in phpMyAdmin 4.7.0 to produce valid JSON data.

The generated JSON is list of objects with following attributes:

type

Type of given object, can be one of:

  • header

    Export header containing comment and phpMyAdmin version.

    database

    Start of a database marker, containing name of database.

    table

    Table data export.

version

Used in header type and indicates phpMyAdmin version.

comment

Optional textual comment.

name

Object name - either table or database based on type.

database

Database name for table type.

data

Table content for table type.

Sample output:

  1. [
  2.     {
  3.         "comment": "Export to JSON plugin for PHPMyAdmin",
  4.         "type": "header",
  5.         "version": "4.7.0-dev"
  6.     },
  7.     {
  8.         "name": "cars",
  9.         "type": "database"
  10.     },
  11.     {
  12.         "data": [
  13.             {
  14.                 "car_id": "1",
  15.                 "description": "Green Chrysler 300",
  16.                 "make_id": "5",

  30.                 "make": "Chrysler",
  31.                 "make_id": "5"
  32.             }
  33.         ],
  34.         "database": "cars",
  35.         "name": "makes",
  36.         "type": "table"
  37.     }
  38. ]

LaTeX

If you want to embed table data or structure in LaTeX, this is right choice for you.

LaTeX is a typesetting system that is very suitable for producing scientific and mathematical documents of high typographical quality. It is also suitable for producing all sorts of other documents, from simple letters to complete books. LaTeX uses TeX as its formatting engine. Learn more about TeX and LaTeX on the Comprehensive TeX Archive Network also see the short description od TeX.

The output needs to be embedded into a LaTeX document before it can be rendered, for example in following document:

  1. \documentclass{article}
  2. \title{phpMyAdmin SQL output}
  3. \author{}
  4. \usepackage{longtable,lscape}
  5. \date{}
  6. \setlength{\parindent}{0pt}
  7. \usepackage[left=2cm,top=2cm,right=2cm,nohead,nofoot]{geometry}
  8. \pdfpagewidth 210mm
  9. \pdfpageheight 297mm
  10. \begin{document}
  11. \maketitle
  13. % insert phpMyAdmin LaTeX Dump here
  15. \end{document}

MediaWiki

Both tables and databases can be exported in the MediaWiki format, which is used by Wikipedia to display tables. It can export structure, data or both, including table names or headers.

OpenOffice 表格

Open standard for spreadsheet data, which is being widely adopted. Many recent spreadsheet programs, such as LibreOffice, OpenOffice, Microsoft Office or Google Docs can handle this format.

OpenOffice 文档

New standard for text data which is being widely adopted. Most recent word processors (such as LibreOffice, OpenOffice, Microsoft Word, AbiWord or KWord) can handle this.

PDF

For presentation purposes, non editable PDF might be best choice for you.

PHP Array

You can generate a php file which will declare a multidimensional array with the contents of the selected table or database.

SQL

Export in SQL can be used to restore your database, thus it is useful for backing up.

The option ‘Maximal length of created query’ seems to be undocumented. But experiments has shown that it splits large extended INSERTS so each one is no bigger than the given number of bytes (or characters?). Thus when importing the file, for large tables you avoid the error “Got a packet bigger than ‘max_allowed_packet’ bytes”.

Data Options

Complete inserts adds the column names to the SQL dump. This parameter improves the readability and reliability of the dump. Adding the column names increases the size of the dump, but when combined with Extended inserts it’s negligible.

Extended inserts combines multiple rows of data into a single INSERT query. This will significantly decrease filesize for large SQL dumps, increases the INSERT speed when imported, and is generally recommended.
