A connection string is used to specify how to connect to the database. Connection strings in Microsoft.Data.Sqlitefollow the standard ADO.NET syntax as a semicolon-separated list ofkeywords and values.

Visual Studio C# project SQLite Not working (1) By John Watson ( JohnSWatson ) on 2021-03-07 08:44:33 link source I am maintaining/building a Windows Forms application (family project) using Visual Studio Community 2019, AForge and SQLite.
- VSCode extension to explore and query SQLite databases. No requirements. Note: The extension includes binaries for the SQLite CLI (used to execute queries), in case the included binaries do not work you need to provide your own path/command for the sqlite3 CLI in the setting sqlite.sqlite3. Query SQLite databases and view results in a table.
- We would like to show you a description here but the site won't allow us.
- SQLite ADO.NET Provider supports advanced Visual Studio integration (DDEX), and provides convenient visual component editors to simplify component tweaking. Broad Compatibility dotConnect for SQLite was the first SQLite database provider to support.NET Core and Entity Framework Core, and we work hard to support new platforms and development.
- SQlite Database in Visual Studio 2019 Getting StartedSqlite is relational database management system which is contained in the a c library.
The following connection string keywords can be used with Microsoft.Data.Sqlite:
Data source
The path to the database file. DataSource (without a space) and Filename are aliases of this keyword.
SQLite treats paths relative to the current working directory. Absolute paths can also be specified.
If empty, SQLite creates a temporary on-disk database that's deleted when the connection is closed.
If :memory:, an in-memory database is used. For more information, see In-Memory databases.
Paths that start with the |DataDirectory| substitution string are treated the same as relative paths. If set, paths are made relative to the DataDirectory application domain property value.
This keyword also supports URI Filenames.
Mode
The connection mode.
| Value | Description |
|---|---|
| ReadWriteCreate | Opens the database for reading and writing, and creates it if it doesn't exist. This is the default. |
| ReadWrite | Opens the database for reading and writing. |
| ReadOnly | Opens the database in read-only mode. |
| Memory | Opens an in-memory database. |
Cache
The caching mode used by the connection.
| Value | Description |
|---|---|
| Default | Uses the default mode of the underlying SQLite library. This is the default. |
| Private | Each connection uses a private cache. |
| Shared | Connections share a cache. This mode can change the behavior of transaction and table locking. |
Password
The encryption key. When specified, PRAGMA key is sent immediately after opening the connection.
Warning
Password has no effect when encryption isn't supported by the native SQLite library.
Note
The Password keyword was added in version 3.0.
Foreign Keys
A value indicating whether to enable foreign key constraints.
Note
The Foreign Keys keyword was added in version 3.0.
| Value | Description |
|---|---|
| True | Sends PRAGMA foreign_keys = 1 immediately after opening the connection. |
| False | Sends PRAGMA foreign_keys = 0 immediately after opening the connection. |
| (empty) | Doesn't send PRAGMA foreign_keys. This is the default. |
There's no need enable foreign keys if, like in e_sqlite3, SQLITE_DEFAULT_FOREIGN_KEYS was used to compile the nativeSQLite library.
Recursive triggers
A value that indicates whether to enable recursive triggers.
Note
The Recursive Triggers keyword was added in version 3.0.
| Value | Description |
|---|---|
| True | Sends PRAGMA recursive_triggers immediately after opening the connection. |
| False | Doesn't send PRAGMA recursive_triggers. This is the default. |
Connection string builder
You can use SqliteConnectionStringBuilder as a strongly typed way of creating connection strings. It can also be used to prevent connection string injection attacks.
Examples
Basic
A basic connection string with a shared cache for improved concurrency.
Encrypted
An encrypted database.
Read-only
A read-only database that cannot be modified by the app.
In-memory
A private, in-memory database.
Sharable in-memory
A sharable, in-memory database identified by the name Sharable.

Features
Query SQLite databases and view results in a table.
Export query results to
json,csvandhtml.Sidebar explorer: list databases, tables, views and columns.
Autocompletion for SQLite keywords, table and views names, column names (autocompletion is available for an SQL document once its bound to a database, to bind an sql document to a database use the command
SQLite: Use Database)Grammar support for SQLite keywords. This is available for documents with language
sqlite. You can mark a document as ansqlitedocument adding-- sqlitein the first line.
Commands
SQLite: New Query Create a new untitled
sqlitefile.SQLite: Run Query Execute query script in the editor.
SQLite: Quick Query Choose a database and execute a query without creating a new document.
SQLite: Use Database Bind current
sqldocument to the selected database.SQLite: Open Database Open the selected database in the sqlite explorer.
SQLite: Close Database Remove the selected database from the sqlite explorer.
SQLite: Refresh Databases Refresh databases open in the sqlite explorer. Php explode.
SQLite: Show output Show the extension's output channel.
SQLite: Change Workspace Trust Change the trust of this workspace. By default every workspace is untrusted for security reasons.
