Advantages of Connectivity to QuestDB from Lazarus via ODBC Driver

Secure Connection

Every operation with QuestDB becomes significantly faster using such capabilities of our driver as local data caching, connection pooling, and much more.

Working with Lazarus using Multiple Functions

Using Lazarus, you can create tables, add data, select, delete, sort, edit, combine data from several database tables, and find unique values quickly and easily.

ODBC Conformance

The driver fully supports the ODBC interface, its data types, and functions. It offers advanced connection string parameters and allows any ODBC-compliant desktop or web application to connect to QuestDB from Lazarus on various platforms.

Simple SQL Querying on Lazarus Files

Lazarus processes SQL through its SQL dialect. Using ODBC connection, it is simple to execute different SQL queries to retrieve entire tables or specific columns from Excel, filter data, format data, numbers, etc.

Cost-Effective Deployment

Installing the driver is easy with the standalone installation file. There is no need in deploying and configuring any additional software which results in a reduction in deployment costs.

Sharing Your Data with Lazarus

You can share your data with other users in Lazarus quickly and easily. Upload your Lazarus data to the SharePoint lists so that it can be available for you and others to use to create reports, data models, dashboards, etc.
