How to Dump SQLite3 Table Data Without the Schema?

Export SQLite3 table data without schema

When working with SQLite3 databases, you may need to export specific tables without schema information. This is useful for transferring data to a different database or just backing up part of your data.

To do this, you can use the .mode and .out commands in a SQLite3 shell session. These commands allow you to specify how the data is exported.

To export table data in SQL format, follow these steps:

1. Open a SQLite3 shell and navigate to the database containing the table you want to export.

2. Execute the following command to set the output mode to "insert":

   <code> .mode insert <目标表名></code>

   Replace <目标表名> with the name of the table you want to export.

3. Use the .out command to configure the output file:

   <code> .out <输出文件名>.sql</code>

   Replace <输出文件名> with the file name and path of the desired SQL dump.

4. Execute the following query to select and export data from the specified table:

   <code> select * from <表名>;</code>

   Replace <表名> with the name of the table you want to export.

The exported data will be saved as a SQL file in a format that can be re-executed to insert the data into another SQLite3 database. This method allows you to easily transfer data between databases or perform partial data backup.
