DBAClientX.SQLite 1.0.8

DbaClientX.SQLite

SQLite provider for DbaClientX (Microsoft.Data.Sqlite). Supports non-query, scalar, queries, streaming, transactions, bulk insert. Also includes SQLite maintenance helpers for online database backup, WAL checkpointing, PRAGMA optimize, and graceful shutdown preparation.

• Target Frameworks: net472 (win-x64), netstandard2.1, net8.0, net10.0
• NuGet: DBAClientX.SQLite

Install

dotnet add package DBAClientX.SQLite

Quick examples

Query table:

var sq = new DBAClientX.SQLite();
var result = sq.Query(
    database: "app.db",
    query: "SELECT Id, Name FROM Users ORDER BY Id"
);

Stream query (netstandard2.1+/net8.0):

await foreach (DataRow row in sq.QueryStreamAsync(
    database: "app.db",
    query: "SELECT Id, Name FROM Users ORDER BY Id",
    cancellationToken: ct))
{
    // consume row
}

Typed mapped query:

var rows = await sq.QueryAsListAsync(
    database: "app.db",
    query: "SELECT Id, Name FROM Users ORDER BY Id",
    map: row => new UserRow(
        Id: row.GetInt32(row.GetOrdinal("Id")),
        Name: row.GetString(row.GetOrdinal("Name"))),
    cancellationToken: ct);

For larger result sets, use QueryStreamAsync<T> with the same mapper shape to avoid buffering all rows.

Execute against a full connection string without losing provider options:

var connectionString = new SqliteConnectionStringBuilder
{
    DataSource = "app.db",
    Mode = SqliteOpenMode.ReadWrite,
    Cache = SqliteCacheMode.Shared,
    Pooling = false,
    DefaultTimeout = 15
}.ConnectionString;

await sq.ExecuteNonQueryWithConnectionStringAsync(
    connectionString,
    "UPDATE Users SET Name = @name WHERE Id = @id",
    new Dictionary<string, object?> { ["@name"] = "Alice", ["@id"] = 1 },
    cancellationToken: ct);

SQLiteGeneric.GenericExecutors.ExecuteSqlAsync accepts either a path or a full connection string. Full connection strings preserve mode, cache, pooling, timeout, password, foreign-key, trigger, and VFS settings. File paths containing = remain valid paths.

Graceful shutdown maintenance:

var sq = new DBAClientX.SQLite();
await sq.PrepareForShutdownAsync(
    database: "app.db",
    options: new SqliteShutdownMaintenanceOptions
    {
        CheckpointMode = SqliteCheckpointMode.Truncate,
        OptimizeAfterCheckpoint = true
    });

Backup before maintenance:

var sq = new DBAClientX.SQLite();
sq.BackupDatabase("app.db", "backups/app.db");
