Vp.FSharp.Sql.Sqlite
An opinionated F# library to interact with SQLite databases following Vp.FSharp.Sql
principles and relying on System.Data.SQLite.Core
.
📝 Note: For the time being, it has been decided to not rely on Microsoft.Data.Sqlite
due to its lack of support for TransactionScope
.
✨ Slagging Hype
We aim at following highly controversial practices to the best of our ability!

📚 How to Use
📝 Note: It's worth noting that the examples below illustrating functions running asynchronously do leverage Async.RunSynchronously
. This is purely for the sake of reducing the nestedness that would happen if we were using async
computation expressions instead.
💿 Supported Database Values
Just a little FYI:
/// Native SQLite DB types.
/// See https://www.sqlite.org/datatype3.html
type SqliteDbValue =
| Null
| Integer of int64
| Real of double
| Text of string
| Blob of byte array
| Custom of DbType * obj
🧱SqliteCommand
The main module is here to help you build and execute SQL(ite) commands (i.e. SQLiteCommand
BTS).
🏗️ Command Construction
We are obviously going to talk about how to build SQLiteCommand
definition.
📝 Note: the meaning of the word "update" below has to be put in a F# perspective, i.e. immutable update, as in the update returns a new updated and immutable instance.
<details> <summary><code>text</code></summary>Initialize a new command definition with the given text contained in the given string.
Example:
use connection = new SQLiteConnection("Data Source=:memory:")
SqliteCommand.text "SELECT 42;"
|> SqliteCommand.executeScalar<int64> connection
|> Async.RunSynchronously
|> printfn "%A"
Output:
42L
</details>
<details>
<summary><code>textFromList</code></summary>
Initialize a new command definition with the given text spanning over several strings (ie. list).
Example:
use connection = new SQLiteConnection("Data Source=:memory:")
[ 0; 1; 1; 2; 3; 5; 8; 13; 21; 34; 55; ]
|> List.map (sprintf "SELECT %d;")
|> SqliteCommand.textFromList
|> SqliteCommand.queryList connection (fun _ _ read -> read.Value<int64> 0)
|> Async.RunSynchronously
|> printfn "%A"
Output:
[0L; 1L; 1L; 2L; 3L; 5L; 8L; 13L; 21L; 34L; 55L]
</details>
<details>
<summary><code>noLogger</code></summary>
Update the command definition so that when executing the command, it doesn't use any logger. Be it the default one (Global, if any.) or a previously overriden one.
Example:
SqliteConfiguration.Logger (printfn "Logging... %A")
use connection = new SQLiteConnection("Data Source=:memory:")
SqliteCommand.text "SELECT 42;"
|> SqliteCommand.noLogger
|> SqliteCommand.executeScalar<int64> connection
|> Async.RunSynchronously
|> printfn "%A"
Output:
42L
</details>
<details>
<summary><code>overrideLogger</code></summary>
Update the command definition so that when executing the command, it use the given overriding logger. instead of the default one, aka the Global logger, if any.
Example:
SqliteConfiguration.NoLogger ()
use connection = new SQLiteConnection("Data Source=:memory:")
SqliteCommand.text "SELECT 42;"
|> SqliteCommand.overrideLogger (printfn "Logging... %A")
|> SqliteCommand.executeScalar<int64> connection
|> Async.RunSynchronously
|> printfn "%A"
Output:
Logging... ConnectionOpened System.Data.SQLite.SQLiteConnection
Logging... CommandPrepared System.Data.SQLite.SQLiteCommand
Logging... CommandExecuted (System.Data.SQLite.SQLiteCommand, 00:00:00.0271871)
Logging... ConnectionClosed (System.Data.SQLite.SQLiteConnection, 00:00:00.1197869)
42L
</details>
<details>
<summary><code>parameters</code></summary>
Update the command definition with the given parameters.
Example:
use connection = new SQLiteConnection("Data Source=:memory:")
SqliteCommand.text "SELECT @a + @b;"
|> SqliteCommand.parameters [ ("a", Integer 42L); ("b", Real 42.42) ]
|> SqliteCommand.executeScalar<double> connection
|> Async.RunSynchronously
|> printfn "%A"
Output:
84.42
</details>
Note: in case you want to pass some types that aren't yet supported by the library,
you can use the Custom
DU case which allows you to pass whatever underlying DbType
with the relevant obj
value.
Update the command definition with the given cancellation token.
This comes in handy when you need to interop with more traditional, C#-async, cancellation style.
Example:
try
use connection = new SQLiteConnection("Data Source=:memory:")
SqliteCommand.text "SELECT 42;"
|> SqliteCommand.cancellationToken (CancellationToken(true))
|> SqliteCommand.executeScalar<int64> connection
|> Async.RunSynchronously
|> ignore
with
| :? OperationCanceledException as e ->
printfn "The Command execution has been cancelled, reason: %A" e.Message
Output:
The Command execution has been cancelled, reason: "A task was canceled."
</details>
<details>
<summary><code>timeout</code></summary>
Update the command definition with the given timeout.
📝 Note about System.Data.SQLite
specifics:
kludged because SQLite doesn't support per-command timeout values.
For a simple select query, no, there doesn't appear to be a way to set a timeout, or maximum time to execute, on SQLite itself. The only mention of timeout in the documentation is the busy timeout. So, if you need to limit the maximum amount of time a select query can take, you'll need to wrap your connection with a timeout in the application level, and cancel/close your connection if that timeout is exceeded. How to do that would obviously be application/language specific.
🔎 Sources:
- StackOverflow:
SQLiteCommand.CommandTimeout
behavior - StackOverflow: Specify
SELECT
timeout for SQLITE
Also it's really when you look at the actual source code powering the System.Data.SQLite
:
SQLiteCommand._commandTimeout
:
/// <summary>
/// The timeout for the command, kludged because SQLite doesn't support per-command timeout values
/// </summary>
internal int _commandTimeout;
</details>
<details>
<summary><code>prepare</code></summary>
Update the command definition and sets whether the command should be prepared or not.
As per MS Docs:
Use the
Prepared
property to have the provider save a prepared (or compiled) version of the query specified in the CommandText property before a Command object's first execution.This may slow a command's first execution, but once the provider compiles a command, the provider will use the compiled version of the command for any subsequent executions, which will result in improved performance.
Example: TBD
</details> <details> <summary><code>transaction</code></summary>Update the command definition and set whether the command should be wrapped in the given transaction.
Example:
let tableName = "people"
use connection = new SQLiteConnection("Data Source=:memory:")
connection.Open()
use transaction = connection.BeginTransaction(IsolationLevel.ReadCommitted)
// Create a table
SqliteCommand.text $"CREATE TABLE {tableName} (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT NOT NULL);"
|> SqliteCommand.transaction transaction
|> SqliteCommand.executeNonQuery connection
|> Async.RunSynchronously
|> printfn "%A"
// The table is created here
SqliteCommand.text $"SELECT COUNT(*) FROM sqlite_master WHERE type='table' AND name='{tableName}';"
|> SqliteCommand.transaction transaction
|> SqliteCommand.executeScalar<int64> connection
|> Async.RunSynchronously
|> printfn "%A"
transaction.Rollback()
// The table creation has been rollbacked
SqliteCommand.text $"SELECT COUNT(*) FROM sqlite_master WHERE type='table' AND name='{tableName}';"
|> SqliteCommand.executeScalar<int64> connection
|> Async.RunSynchronously
|> printfn "%A"
Output:
0
1L
0L
</details>
⚙ Command Execution
We are obviously going to talk about how to execute SQLiteCommand
definitions.
Execute the command and return the sets of rows as an
AsyncSeq
accordingly to the command definition.This function runs asynchronously.
Example 1:
type Row<'T> = { Set: int32; Record: int32; Data: 'T list }
let getCounterQuery n =
sprintf
"""
WITH RECURSIVE counter(value) AS (VALUES(1) UNION ALL SELECT value + 1 FROM counter WHERE value < %d)
SELECT value FROM counter;
""" n
let readRow set record (read: SqlRecordReader<_>) =
{ Set = set; Record = record; Data = List.init (read.Count) (read.Value<int64>) }
use connection = new SQLiteConnection("Data Source=:memory:")
[ 0; 1; 1; 2; 3; 5 ]
|> List.map getCounterQuery
|> SqliteCommand.textFromList
|> SqliteCommand.queryAsyncSeq connection readRow
|> AsyncSeq.toListSynchronously
|> List.iter (fun x -> printfn "Set = %A; Row = %A; Data = %A" x.Set x.Record x.Data)
Output 1:
Set = 0; Row = 0; Data = [1L]
Set = 1; Row = 0; Data = [1L]
Set = 2; Row = 0; Data = [1L]
Set = 3; Row = 0; Data = [1L]
Set = 3; Row = 1; Data = [2L]
Set = 4; Row = 0; Data = [1L]
Set = 4; Row = 1; Data = [2L]
Set = 4; Row = 2; Data = [3L]
Set = 5; Row = 0; Data = [1L]
Set = 5; Row = 1; Data = [2L]
Set = 5; Row = 2; Data = [3L]
Set = 5; Row = 3; Data = [4L]
Set = 5; Row = 4; Data = [5L]
Notes 📝:
- The output type must be consistent across all the result sets and records.
- If you need different types you may want to either:
- Create DU with each type you want to output
- Use
querySetList2
orquerySetList3
⬇️
- The
read
er can also get theValue
given a certain field name:
Example 2:
use connection = new SQLiteConnection("Data Source=:memory:")
[ 0; 1; 1; 2; 3; 5; 8; 13; 21; 34; 55; ]
|> List.map (sprintf "SELECT %d AS cola;")
|> SqliteCommand.textFromList
|> SqliteCommand.queryList connection (fun _ _ read -> read.Value<int64> "cola")
|> Async.RunSynchronously
|> printfn "%A"
Output 2:
[0L; 1L; 1L; 2L; 3L; 5L; 8L; 13L; 21L; 34L; 55L]
</details>

[ 0; 1; 1; 2; 3; 5 ]
|> List.map getCounterQuery
|> SqliteCommand.textFromList
|> SqliteCommand.querySeqSync connection readRow
|> Seq.iter (fun x -> printfn "Set = %A; Row = %A; Data = %A" x.Set x.Record x.Data)
Output 1:
Set = 0; Row = 0; Data = [1L]
Set = 1; Row = 0; Data = [1L]
Set = 2; Row = 0; Data = [1L]
Set = 3; Row = 0; Data = [1L]
Set = 3; Row = 1; Data = [2L]
