# .NET Core Batch Update

Using ADO.NET bulk update to create data on MSSQL.

> This example follows AdventureWorks [naming conventions][3]

## Creating the database

For local development, launch a docker instance:

```sh

docker run -e "ACCEPT_EULA=Y" -e "MSSQL_SA_PASSWORD=Str0ngP4ssword#2023" --name mssql-powerapps -p 1433:1433 -d mcr.microsoft.com/mssql/server:2022-latest

```

For real performance testing, start a database on Azure.

Make sure you have the Bicep latest release:

```sh

az bicep upgrade

```

Create the resources on Azure:

> 💡 Edit security and location parameters according to your needs - this code is only for demo purposes

```sh

# Edit the required values

cp config-template.json config.json

# Run the Bicep template

az deployment group create --resource-group powerapps --template-file main.bicep

```

Switching the DTU capacity during benchmark:

```sh

# Options with DTU are S0(10), S1(20), S2(50), S3(100)...

az sql db update -g powerapps -s sqlpowerappsbenchmark -n sqldbbenchmark --service-objective S3 --max-size 250GB

# Go back to Basic to save costs

az sql db update -g powerapps -s sqlpowerappsbenchmark -n sqldbbenchmark --service-objective Basic --max-size 2GB

```

> ℹ️ Read ore about capacity options in the [purchasing models][1] documentation.

> 💡 DTU model supports columnstore indexing starting from `S3` and above

## Create the schema

The sample schema compatible with this code is available in the [`schema.sql`](/tsql/schema.sql) file.

Use your fav IDE such as Azure Data Studio to create the objects.

## Run the batch

After creating the schema, enter the console app directory to set it up.

```sh

cd dataload

cp template.env .env

```

Get the database connection string:

```sh

az sql db show-connection-string -s sqlpowerappsbenchmark -n sqldbbenchmark -c ado.net

```

Add the connection string to the `.env` file, replacing the username and password.

Run the application:

```sh

dotnet restore

dotnet run

```

The console app will use bulk update to create the data.

---

When finished, delete the resources:

```sh

az group delete -n powerapps -y

```
