SQLiteToCSV
Provides the means to copy SQLite query results to a CSV file with your choice of delimiter. I originally wrote this program in about 30 lines of Python code, but found that for extremely large SQLite databases I wasn't getting the performance that I needed. Hence this...
Building
Ensure that you have a C compiler installed (GCC preferred). Next,
install the SQLite library. If using the apt package manager, this is
accomplished by the following command, some Linux distros may already include this.
sudo apt install libsqlite3-dev
Next, clone the project from GitHub and change directory.
git clone https://github.com/dustinkredmond/SQLiteToCSV && cd SQLiteToCSV
To compile from source, run the following (requires CMake and Make)
cmake . && make
An executable will be generated, run it as so.
./SQLiteToCsv
Command line options
- -db - Path to SQLite database
- -out - Path to export CSV file
- -delimiter - Delimiter to use in CSV file (optional) defaults to comma if not provided
- -sql - SQL query to retrieve from database
- -prompt - Prompt the user to continue (doesn't by default)
- -help - Print information seen here
Usage
Let's say we have a database called Test.db in the current working directory.
Test.db has a table EMPLOYEE. If we wanted a subset of the records in this
table we could make a call to SQLiteToCSV like below.
./SQLiteToCSV -db ./Test.db -out ./Test.csv -sql "SELECT * FROM EMPLOYEE WHERE DEPARTMENT_ID = 15"This would in turn run the query against the SQLite database, and pop out a Test.csv file
in the directory specified.
Not supported
BLOBs or other binary objects. Instead, the string '<BLOB format not supported>' will be written.
