# FSharp.Data.SqlClient - Type providers for Microsoft SQL Server
This library exposes SQL Server Database objects in a type safe manner to F# code, by the mean of [Type Providers](https://docs.microsoft.com/en-us/dotnet/fsharp/tutorials/type-providers/)
You can reference it in F# Interactive that ships with Visual Studio
```fsharp
#r "nuget: FSharp.Data.SqlClient"
open FSharp.Data
open FSharp.Data.SqlClient
let [] connectionString = "Server=.;Database=AdventureWorks2012;Trusted_Connection=True;"
type MyCommand = SqlCommandProvider<"""
select
data.a
from
(select 1 a union all select 2 union all select 3) data
where
data.a > @data
""", connectionString>;;(new MyCommand(connectionString)).Execute(data=1)
|> Seq.toArray
|> printfn "%A"
````dotnet fsi` is not supported yet.

## Type Providers### SqlCommandProvider
Provides statically typed access to the parameters and result set of T-SQL command in idiomatic F# way (*).
```fsharp
open FSharp.Data[]
let connectionString = "Data Source=.;Initial Catalog=AdventureWorks2012;Integrated Security=True"// The query below retrieves top 3 sales representatives from North American region with YTD sales of more than one million.
do
use cmd = new SqlCommandProvider<"
SELECT TOP(@topN) FirstName, LastName, SalesYTD
FROM Sales.vSalesPerson
WHERE CountryRegionName = @regionName AND SalesYTD > @salesMoreThan
ORDER BY SalesYTD
" , connectionString>(connectionString)cmd.Execute(topN = 3L, regionName = "United States", salesMoreThan = 1000000M) |> printfn "%A"
```
output
```fsharp
seq
[("Pamela", "Ansman-Wolfe", 1352577.1325M);
("David", "Campbell", 1573012.9383M);
("Tete", "Mensa-Annan", 1576562.1966M)]
```### SqlProgrammabilityProvider
Exposes Tables, Stored Procedures, User-Defined Types and User-Defined Functions in F# code.
```fsharp
type AdventureWorks = SqlProgrammabilityProvider
do
use cmd = new AdventureWorks.dbo.uspGetWhereUsedProductID(connectionString)
for x in cmd.Execute( StartProductID = 1, CheckDate = System.DateTime(2013,1,1)) do
//check for nulls
match x.ProductAssemblyID, x.StandardCost, x.TotalQuantity with
| Some prodAsmId, Some cost, Some qty ->
printfn "ProductAssemblyID: %i, StandardCost: %M, TotalQuantity: %M" prodAsmId cost qty
| _ -> ()
```
output
```fsharp
ProductAssemblyID: 749, StandardCost: 2171.2942, TotalQuantity: 1.00
ProductAssemblyID: 750, StandardCost: 2171.2942, TotalQuantity: 1.00
ProductAssemblyID: 751, StandardCost: 2171.2942, TotalQuantity: 1.00
```### SqlEnumProvider
Let's say we need to retrieve number of orders shipped by a certain shipping method since specific date.
```fsharp
//by convention: first column is Name, second is Value
type ShipMethod = SqlEnumProvider<"
SELECT Name, ShipMethodID FROM Purchasing.ShipMethod ORDER BY ShipMethodID", connectionString>//Combine with SqlCommandProvider
do
use cmd = new SqlCommandProvider<"
SELECT COUNT(*)
FROM Purchasing.PurchaseOrderHeader
WHERE ShipDate > @shippedLaterThan AND ShipMethodID = @shipMethodId
", connectionString, SingleRow = true>(connectionString)
//overnight orders shipped since Jan 1, 2008
cmd.Execute( System.DateTime( 2008, 1, 1), ShipMethod.``OVERNIGHT J-FAST``) |> printfn "%A"
```
output
```fsharp
Some (Some 1085)
```### SqlFileProvider
```fsharp
type SampleCommand = SqlFile<"sampleCommand.sql">
type SampleCommandRelative = SqlFile<"sampleCommand.sql", "MySqlFolder">use cmd1 = new SqlCommandProvider()
use cmd2 = new SqlCommandProvider()
```More information can be found in the [documentation](http://fsprojects.github.io/FSharp.Data.SqlClient/).
