Setup

TODO: Common traits

Postgres

1. Start Postgres DB

cd postgres
docker-compose up

NOTE: This will create the database perftest and all tables initially.

2. Connect with your favorite DB client``

"server": "localhost",
"port": 5432,
"username": "perftest",
"password": "example",
"database": "perftest"

3. Run sample queries, e.g. postgres/sql/primary-keys.sql

The sample queries are creating execution plans, i.e. they use EXPLAIN.

SQL Server

1. Start SQL Server

cd mssql
docker-compose up

NOTE: This will create the database perftest and all tables initially.

2. Connect with your favorite DB client

"server": "localhost",
"port": 1433,
"username": "sa",
"password": "SuperStrong@Passw0rd",
"database": "perftest"

3. Run sample queries, e.g. mssql/sql/primary-keys.sql

The sample queries are creating execution plans, i.e. they use set SET STATISTICS PROFILE ON and SET STATISTICS PROFILE OFF afterwards. This generates two results: The actual result and another one for the execution plan.
