The Yugabyte Structured Query Language (YSQL) API builds upon and extends a fork of the query layer from PostgreSQL 11.2, with the intent of supporting most PostgreSQL functionality and adding new functionality to supported distributed SQL databases.

For details on PostgreSQL feature support in YSQL, see What Features Does YSQL Support?

Yugabyte and third party API client library drivers listed below are supported for developing applications that connect to and interact with the YSQL API.

For help using these drivers with YSQL, ask questions in the Slack community.

If you encounter an issue or want to file an enhancement request, file a GitHub issue.

C

libpq

libpq is the C client library for connecting to and interacting with PostgreSQL databases. libpq is also the underlying engine used in other PostgreSQL application interfaces. The libpq client library also supports the SCRAM-SHA-256 authentication protocol that was added in PostgreSQL 10.

For details and documentation, see libpq - C Library for PostgreSQL 11, which YugabyteDB is based on.

For a tutorial on building a sample C application with libpq, see Build a C application.

To install the libpq client library

The libpq C driver is included in the YugabyteDB installation. You can use it by setting the LD_LIBRARY_PATH as follows :

$ export LD_LIBRARY_PATH=<yugabyte-install-dir>/postgres/lib

C++

libpqxx

The libpqxx driver is the official C++ client API for PostgreSQL. libpqxx is based on libpq and supports the SCRAM-SHA-256 authentication protocol that was added in PostgreSQL 10.

For details and documentation, see jvt/libpqxx README and libpqxx ReadTheDocs.

For a tutorial on building a sample C++ application with libpqxx, see Build a C++ application.

Install the libpqxx driver

To build and install the libpqxx driver for use with YugabyteDB, follow these steps:

  1. Clone the libpqxx repository.
$ git clone https://github.com/jtv/libpqxx.git
  1. For dependencies on the PostgreSQL binaries, add the PostgreSQL bin directory to the command path by running the following command.
$ export PATH=$PATH:<yugabyte-install-dir>/postgres/bin
  1. Build and install the driver.
$ cd libpqxx
$ ./configure
$ make
$ make install

C#

Npgsql

Npgsql is an open source ADO.NET Data Provider for PostgreSQL that enables C# applications to connect and interact with PostgreSQL databases. Npgsql is based on libpq and supports the SCRAM-SHA-256 authentication protocol that was added in PostgreSQL 10.

For details on installing and using Npgsql, see Npgsql documentation.

To follow a tutorial on building a sample C# application with Npgsql, see Build a C++ application.

Install the driver

To install Npgsql in your Visual Studio project, follow the steps below.

  1. Open the Project Solution View.

  2. Right-click on Packages and click Add Packages.

  3. Search for Npgsql and click Add Package.

Go

Go PostgreSQL driver (pq)

The Go PostgreSQL driver package (pq) is a Go PostgreSQL driver for the database/sql package. pq is not based on the libpq client library, but supports the SCRAM-SHA-256 authentication protocol.

For a tutorial on building a sample Go application with pq, see Build a Go application.

Install the pq driver

To install the package locally, run the following go get command:

$ go get github.com/lib/pq

The pq driver is ready for building Go applications that connect to and interact with YugabyteDB.

Java

PostgreSQL JDBC Driver (PgJDBC)

The PostgreSQL JDBC Driver is the official PostgreSQL driver. PgJDBC is not based on libpq, but supports the SCRAM-SHA-256 authentication protocol.

For a tutorial on building a sample Go application with the PostgreSQL JDBC Driver, see Build a Java application and click YSQL-JDBC.

Install the PostgreSQL JDBC Driver

To download binary JAR files, go to PostgreSQL JDBC Driver – Downloads. Because Java is platform neutral, download the appropriate JAR file and drop it into the classpath.

To get the latest versions for projects using Apache Maven, see Maven Central Repository Search.

YugabyteDB JDBC Driver [BETA]

The YugabyteDB JDBC Driver is based on the PostgreSQL JDBC Driver (PgJDBC) and incorporates all of the functionality and behavior of that driver. The YugabyteDB JDBC driver extends PgJDBC to add support for features important for distributed SQL databases created in YugabyteDB universes: cluster awareness, connection pooling, and load balancing.

For details, see YugabyteDB JDBC Driver in this section.

Node.JS

node-postgres

node-postgres is a collection of Node.js modules for interacting with PostgreSQL databases. node-postgres optionally uses libpq and supports the SCRAM-SHA-256 authentication protocol that was added in PostgreSQL 10.

For details on installing and using node-postgres, see the [node-postgres documentation].

For a tutorial on building a sample Node.js application with node-postgres, see Build a Node.js application.

Install the node-postgres (pg) driver

To install node-postgres and any packages it depends on, run the following npm install command:

$ npm install pg

PHP

php-pgsql

The php-pgsql driver is a collection of the official PostgreSQL module for PHP. php-pgsql is based on libpq and supports the SCRAM-SHA-256 authentication protocol.

For a tutorial on building a sample Node.js application with php-pgsql, see Build a Node.js application.

Install the php-pgsql driver

To enable PostgreSQL support using php-pgsql, see [Installing/Configuring] in the PHP documentation.

Python

psycopg2

Psycopg is the popular PostgreSQL database adapter for the Python programming language. psycopg2 is based on libpq and supports the SCRAM-SHA-256 authentication protocol that was added in PostgreSQL 10.

For details on using psycopg2, see Psycopg documentation.

For a tutorial on building a sample Python application that uses psycopg2, see Build a Python application.

Install the psycopg2 binary

To install the psycopg2 binary package, run the following pip install` command:

$ pip3 install psycopg2

Ruby

pg

pg is the Ruby interface for PostgreSQL databases. pg is based on libpq and supports the SCRAM-SHA-256 authentication protocol.

For a tutorial on building a sample Ruby application with pg, see Build a Ruby application.

Install the pg driver

To install pg driver, run the following gem install command:

$ gem install pg -- --with-pg-config=<yugabyte-install-dir>/postgres/bin/pg_config
