Sql.js allows you to easily import and export SQLite databases. And it can be used both in a browser and in Node.js!Thanks to this, this tool is only executed on the browser side. It can be used like any javascript library. ![]() Sql.js is a port of SQLite to JavaScript by compiling the SQLite C code with Emscripten, it is MIT licensed. To see more visit About SQLite compiled to javascript (sql.js) There are several appropriate uses for SQLite: SQLite is public domain, it is free to everyone to use for any purpose,it is the most used database engine in the world! SQLite has a full-featured SQL implementation (Tables, indexes, triggers, SELECT, UPDATE, DELELE, VACUUM. Data are contained in a single disk file, SQLite reads and writes directly to disk files.SQLite is cross-platform! SQLite is an embedded SQL database engine. ).SQLite provides local data storage for applicationswhile client/server SQL database engines implements a shared repository of data. SQLite is not directly comparable to client/server SQL database engines (PostgreSQL, MySQL. This tool does not require installation, it is totally online, you can make SQL online.Just have a simple browser to use it!It can help to make tests quickly or when it is not possible to install software on its server. You do not have to know the SQL commands to use this tool. For everyday use, a fat client may seem more appropriate. This small tool is useful and allows not to have to install a fat client for occasional use. This SQL viewer online allows you to make SQL online test, you can SQL practice online.Thanks to sharing mode, you can be several to test an online SQL database. After your database is created and your first table is added, you can add some records.This SQLite viewer allows you to open SQLite file online in order to create, query, and edit SQLite database files.It is useful for developers wanting to query a database file,it can help test and debug data from a sqlite database.This SQLite playground can also be useful for non-developers. If the tool categories are “hammer,” “spanner,” and “screwdriver,” you can’t add a record of type “chisel.”Ĭlick “OK” after you add the fields you want. For example, in a database of workshop tools, you might have a table of individual tools and another table of tool categories. Foreign Key: A field or group of fields in a record that must match a key in another table. ![]() In most cases, you can leave this to the default value. Other options are NOCASE, which is case-insensitive, and RTRIM, which ignores trailing white space. Collation: Sqlite can use different methods of string comparison.For example, you might check that the value in a phone number field has at least 10 characters. Check: A field can have a check performed on it when a record is added.Default: A default value will be provided if a record is added that has no value in this field.U (Unique): This field in each record must hold a unique value, meaning there can’t be any duplicates in this field in the table.We used this in the “id” field in the example we covered above. AI (Auto-Incrementing): Numeric fields can be automatically filled in, with the next highest unused value.There can only be one primary key in a table. ![]() In a table of user accounts, though, it might be a username. This might be a simple numeric value, like the auto-incrementing integer fields we covered above.
