HTTPS Connections without Certificate Validation

Note

Using these setups, no certificate validation of any kind will be performed; not recommended for production deployments.

To bypass certificate checks in JDBC, see Secure Connections. To bypass certificate checks in KiSQL, see Parameterized Options.

Compatibility Matrix

The following chart shows the version compatibilities between the various APIs and a target database server. While only the major & minor version numbers (6.2, 7.0, 7.1) must match to achieve interoperability, the complete feature set for a given database version can only be utilized via the corresponding API version, depicted below.

Database	C++	C#	Java	Javascript	Node.js	Python
6.2	6.2.*	6.2.*	6.2.*	6.2.*	6.2.*	6.2.*
7.0.X	7.0.X	7.0.X	7.0.X	7.0.X	7.0.X	7.0.X
7.1.X	7.1.X	7.1.X	7.1.X	7.1.X	7.1.X	7.1.X

Dynamic Schemas

When working with APIs, it is helpful to have an understanding of how data is returned by the database. For a detailed breakdown in Java & Python, see Dynamic Schemas.
