Everything is stored as either a long, double, string, or blob. And in SQLite version 2, everything is stored as a string. Precompiled Binaries for Windows: sqlite-dll-win32-x86-3140100.zip (423.97 KiB) 32-bit DLL (x86). Visit the System.Data.SQLite.org website and especially the download page for source code and binaries of SQLite for.NET.So you need to be careful about avoiding casting values returned by SQLite without checking the type of the value returned. See below for notes on storing Date. Times. New style assembly shipped with Mono 1. Starting with the 1. Mono ships a second SQLite assembly - Mono. Introduction to SQLite C#. The Mono.Data.Sqlite assembly contains an ADO.NET data provider for the SQLite database. It is written in C# and is available for all CLI languages: C#, Visual Basic, Boo, and others. About System.Data.SQLite. System.Data.SQLite is an ADO.NET provider for SQLite. System.Data.SQLite was started by Robert Simpson. Robert still has commit privileges on this repository but is no longer an. Data. Sqlite. The new assembly provides support only for SQLite version 3and is not 1. API compatible with the older assembly. The new assembly is based on code by Robert Simpson from http: //sqlite. ADO. NET 2. 0 API interface. Code from the old binary is contained in the new one but is available only in the 1. The 2. 0 profile can no longer access the old code when referencing the new assembly. We have chosen this way as means to provide a migration path for developers using SQLite in their . NET applications - both assemblies will be shipped with several future releases of Mono, and at some (yet undetermined) point the old one will be removed from the distribution. All the developers are encouraged to start transitioning their code to the new assembly - for both 1. One disadvantage of the new assembly is its binary incompatibility in the data format. That is, if your application uses SQLite database v. To solve this problem you must dump your data using sqlite v. Prerequisites. If you do not have SQLite, download it. There are binaries for Windows and Linux. You can put the . Connection String Format. The Mono.Data.SqliteClient assembly contains an ADO.NET data provider for the SQLite embeddable database engine. Mono ships a second SQLite assembly - Mono.Data.Sqlite. There are binaries for Windows and Linux. Hello, > I'm trying to get phxsoftware's System.Data.SQLite managed-only dll > working under mono. The readme claims i should just need the binary in > the same directory and it works for mono. It does work for windows, i. The format of the connection string is. It will be created if it does not exist. Or you prefer to use SQLite as an in memory database. URI=file: :memory: ,version=3. The version=3 is supported, but not necessary with the new assembly. With the old assembly, the ADO. NET adapter will use SQLite version 2 by default, but if version 2 is not found and version 3 is available, it will fallback to version 3. You can force the adapter to use version 3 by adding . The default value is 0, which means to throw a Sqlite. Busy. Exception immediately if the database is locked. For the 2. 0 profile in the new assembly. Parameter Definition. Description. Example. Data Sourcea file Universal Resource Identifier. Data Source=file: Sqlite. Test. dbversionversion of SQL Lite to use: version 3version=3. Storing Date. Times. The way Date. Times are stored and retrieved from Sqlite databases depends on a lot, unfortunately, because Sqlite doesn. Further, there are two versions of Sqlite (2 and 3) which are treated differently when it comes to Date. Times. The recommended way of using Date. Times with Sqlite is to encode/decode them yourself to/from some particular integer string format that you decide, and not putting them into a DATE or DATETIME column. Sqlite. 2 only has strings internally. No matter what the column was declared as, Date. Times are just going to be converted into strings. If you use parameters, for instance, Date. Times will be converted in a culture- sensitive format. When reading back the data, there. Using Sqlite. 2, you really can. Sqlite. 3 has string, integer (6. When putting a Date. Time into the database using parameters, Mono. Data. Sqlite. Client will encode the Date. Time as an integer using To. File. Time(). Sqlite. If a column is declared as a DATE or DATETIME, Sqlite. Data. Reader will try to turn the value back into a Date. Time. If it finds an integer value, it uses Date. Time. From. File. Time, which is the reverse of how it encodes Date. Times if you insert a Date. Time via parameters. If it finds a string value, it uses Date. Time. Parse, but note that Parse is a very slow operation. So with Sqlite. 3, Date. Times should be put into DATE or DATETIME columns in the database either through parameters or by turning it into a long with To. File. Time yourself, and then they will be read back as Date. Times. Character Encodings. The Sqlite client treats character encodings differently for version 2 and version 3 because of the way Sqlite. In Sqlite. 3, the Sqlite client communicates with Sqlite in Unicode. Therefore, you should be able to read and write any characters from the database, but note that if you write Unicode characters to a database, you may not be able to read them back in other applications if the application does not communicate with Sqlite using Unicode. In Sqlite. 2, the client by default communicates with Sqlite using the UTF- 8 encoding, which means you can read and write any character. But you must beware of two things. The first is that since non- ASCII characters are encoded as multi- byte characters in UTF- 8, and Sqlite. The second caveat is that other applications using the database must be using UTF- 8 as well. When using Sqlite. Mono. Data. Sqlite. Client to use a different encoding instead of UTF- 8 by adding . It must be an encoding that ends with a single null terminator, however. C# Example (1. 1 profile of the new assembly and the old assembly) using System. System. Data. using Mono. Data. Sqlite. Client. Re- installing the application may fix this problem.(example).
