Microsoft SQL Server

Overview

Microsoft SQL Server is a relational database engine for enterprise workloads. It provides T-SQL, columnstore indexes, in-memory OLTP, Always On availability groups, and integrated analytics. SQL Server is available on-premises, on Azure SQL Database, Azure SQL Managed Instance, and Amazon RDS.

Driver

Crate: tiberius
Version: 0.12

Connection fields

Field	Description
Host	Hostname or IP address of the SQL Server instance.
Port	TCP port the server listens on.
Database	Name of the database to connect to.
User	SQL Server authentication username.
Password	Authentication password. Stored in the macOS Keychain.
SSL Mode	One of `disable`, `prefer`, `require`, `verify-ca`, or `verify-full`.
Options	Additional connection parameters as `key1=val1&key2=val2`.

All connections also support an optional SSH tunnel. Configure the bastion host, port, user, and private key file under the SSH section of the connection form. See SSH tunnels for details.

URI format

Instead of filling in each field individually, you can paste a connection URI into the Paste URI field. Arris parses the URI and populates all fields automatically.

text Connection URI

mssql://user:password@host:1433/dbname?encrypt=true

SSL & TLS

SQL Server supports five SSL modes. Arris defaults to prefer, which uses SSL if the server supports it but falls back to unencrypted if not.

SSL Mode	Behavior
`disable`	Never use SSL. Not recommended for production.
`prefer`	Use SSL if available, fall back to unencrypted.
`require`	Always use SSL. Fail if the server does not support it.
`verify-ca`	Require SSL and verify the server certificate against a CA.
`verify-full`	Require SSL, verify the CA, and verify the server hostname matches the certificate.

Schema browser

Once connected, Arris fetches the schema tree from system catalog views and organizes it into groups. The default schema filter is set to dbo, but you can add or remove schemas from the filter dropdown in the sidebar.

The schema tree displays the following object types, grouped by category:

Tables — regular tables
Views — views
Routines — functions and stored procedures
Sequences — sequences
Types — user-defined types
Triggers — table-level triggers
Indexes — clustered and non-clustered indexes

Double-click any table or view to open it in a new tab with browse mode.

Supported SQL commands

Command	Notes
`SELECT`	Query data with `WHERE` filters, `JOIN`s, aggregates, and window functions.
`INSERT`	Insert single or multiple rows.
`UPDATE`	Update existing rows.
`DELETE`	Delete rows.
`CREATE` / `DROP`	Create and drop tables, views, and other schema objects.
