MSSQL Lineage Scanner

Scanned and supported objects

Supported statements types are as follows:

CREATE TABLE AS SELECT
CREATE VIEW
INSERT
MERGE
SELECT
UPDATE

Supported database objects for Design Time Lineage are as follows:

Views
Materialized views
Lineage for stored procedures
Local and global temporary tables (created within stored procedures)

Limitations

The following SQL constructs are not supported. This means that statements containing these SQL constructs will not be included in the lineage diagram.

Table value constructor
Table functions
References to linked server objects

Lineage is also not supported for:

Jobs
Dynamic SQL
Computed columns

Supported connectivity

Connector type: JDBC.
Authentication method: SQL Server Authentication using SQL login and password.

MSSQL permissions

To ensure the scanner can access the necessary system views, the following database permissions must be granted:

Server-level permissions

VIEW ANY DATABASE: Allows the user to view metadata about all databases on the SQL Server instance. Required for querying the master.sys.databases view.

You can use the following command to set this permission:
```
GRANT VIEW ANY DATABASE TO [YourUserOrRole];
```

Database-level permissions

The user connecting to the scanner database needs to be able to query these system views for each scanned database:

INFORMATION_SCHEMA.TABLES
INFORMATION_SCHEMA.COLUMNS
INFORMATION_SCHEMA.ROUTINES
SYS.VIEWS
SYS.SCHEMAS
SYS.SQL_MODULES

User permissions

The user must have the following permissions:

CONNECT: Allows the user to connect to the database.

USE [YourDatabaseName]; GRANT CONNECT TO [YourUserOrRole];

VIEW DEFINITION: Allows the user to view the metadata of database objects. Required for accessing the schema and system views listed in previous sections.
```
USE [YourDatabaseName]; GRANT VIEW DEFINITION TO [YourUserOrRole];
```
