PostgreSQL Connector – Domo

Intro

PostgreSQL is a widely used open-source relational database management system. You can use Domo's PostgreSQL Connector to pull data from your PostgreSQL database and compile custom reports. You indicate the data you want by inputting an SQL query. For more information about the PostgreSQL API, visit their website. ( https://www.postgresql.org/docs/ )

The PostgreSQL connector is a "Database" connector, meaning it retrieves data from databases using a query. In the Data Center, you can access the connector page for this and other Database connectors by clicking Database in the toolbar at the top of the window.

You connect to your PostgreSQL database in the Data Center. This topic discusses the fields and menus that are specific to the PostgreSQL connector user interface. General information for adding DataSets, setting update schedules, and editing DataSet information is discussed in Adding a DataSet Using a Data Connector.

Note: Depending on your network's structure, your IT administrator may need to whitelist any IP addresses necessary for the data connector to retrieve data. Contact your IT administrator for assistance.

Primary Use Cases	This connector is appropriate for pulling database information into Domo.

Best Practices

Use read-only queries only.
Use "Replace" instead of "Append."

Prerequisites

To connect to a PostgreSQL database and create a DataSet, you must have the following:

The username and password you use to log into your PostgreSQL database
The host name for the database
The port number for the database
The database name

CA certificate text or URL path is required only if you select Certificate text or URL path, respectively, in the Certificate type menu.

Before you can connect to a PostgreSQL database, you must also whitelist a number of IP addresses on your database server on the port you want to connect to. For the full list of IP addresses, see Whitelisting IP Addresses for Connectors.

Connecting to Your PostgreSQL Database

This section enumerates the options in the Credentials and Details panes in the PostgreSQL Connector page. The components of the other panes in this page, Scheduling and Name & Describe Your DataSet, are universal across most connector types and are discussed in greater length in Adding a DataSet Using a Data Connector.

Credentials Pane

This pane contains fields for entering credentials to connect to your database. The following table describes what is needed for each field:

Field	Description
Username	Enter your PostgreSQL username.
Password	Enter your PostgreSQL password.
Host	Enter the host name for the SQL database. For example: db.company.com
Port	Enter the port number for the database.
Certificate	Paste the text for your CA certificate or enter the URL where your certificate is located. This is optional. If you do not want to include a certificate, select No certificate in the Certificate Type menu.
Certificate Type	Select a certificate type. If you do not want to include a certificate, select No certificate. If you select Certificate text, you must paste the text for your certificate in the Certificate field. If you select URL path, you must enter the URL where your certificate is located in the Certificate field.
Database	Enter the name of the SQL database.

Once you have entered valid PostgreSQL credentials, you can use the same account any time you go to create a new PostgreSQL DataSet. You can manage connector accounts in the Accounts tab in the Data Center. For more information about this tab, see Managing User Accounts for Connectors.

Details Pane

In this pane you create an SQL query to pull data from your database.

Description

Query Type

Select a query type

Query Type	Description
Query Builder	Build an SQL query by selecting the database table and table columns.
Custom Query	Write a customized SQL query with or without parameter.

SQL Query

Enter the Structured Query Language (SQL) query to use in selecting the data you want. For example:

select * from Employee

Query Parameter (Check box)

Select this checkbox to add query parameters.

Query Parameter (Text box)

Enter the query parameter value. It is the initial value for query parameter. The last run date is optional. By default it is '02/01/1700' if is not provided. Example: !{lastvalue:_id}!=1,!{lastrundate:start_date}!=02/01/1944

Fetch Size Enter fetch size for memory performance. If it is blank, default value will be 400.

BigInt To Long

Select to always convert a bigint column to a long column in Domo.
This means even if the bigint column stores small integer values, Domo will still consider the column to have long values.

Database Table

Select the database table you want to appear in your report.

Table Columns

Select the table columns you want to appear in your report.

Query Helper

Copy and paste this query into the Query field if you need help building a query. This query is automatically generated when you select a table and columns in the Database Table and Table Columns fields, respectively.

Other Panes

For information about the remaining sections of the connector interface, including how to configure scheduling, retry, and update options, see Adding a DataSet Using a Data Connector.

Troubleshooting

Make sure the appropriate IP addresses are whitelisted (see Prerequisites for a list of IP addresses).
Try decreasing fetch size or leave it empty.

Can we please update this documentation to reflect that connector requires an RSA private key and will not work with any other type? This caused some confusion for one of our customers!
Thanks!
