![]() ![]() Note that there are some exceptions to this rule. However, SQLite uses manifest typing, which allows the storage of any amount of any data type into any column without no matter the column's declared datatype. That is, you can only store values of the same datatype that is associated with a particular column. Manifest Typing: The majority of SQL database engines rely on static typing.This also makes it simple to share since database files can easily be copied onto a memory stick or sent through email. Simple Database Files: A SQLite database is a single ordinary disk file that can be stored in any directory.There is no need for database administrators to assign instances or manage user access permissions. No need for servers: That is, there are no server processes that need to start, stop or be configured.However, SQLite is another useful RDBMS that is very simple to set up and operate that has many distinct features over other relational databases. After your database is created and your first table is added, you can add some records.If you are familiar with relational database systems, it is likely that you have heard of heavyweights such as MySQL, SQL Server or PostgreSQL. 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. ![]()
