#Sqlite schema code#
The following code uses the file-analysis framework to get the sha1 hashes
For example, consider the following usersexport.sql schema & values.
#Sqlite schema how to#
the schema, is chosen by the program that creates the database. Refer to how to convert an existing SQLite file first. SQLite is just a container format the choice of what can go where in the DB, i.e. Data is stored in a local file under a well-documented file format. Note that this will create 2 different database files sqlite>. SQLite ( ) is a local Database Management System. Sqlite> select * from main.test1 where > 0 Sqlite> select * from test1 where test1.id > 0 Now we can use myotherdb to refer to this new database, and no prefix or the main prefix to refer to the first/default database sqlite> select * from myotherdb.test1 where > 0 The schemaversion pragma gets or sets the schema version value that is stored in the database header. Sqlite> create table myotherdb.test1 (id int) insert into myotherdb.test1 values (2) A contract class is a container for constants that define names for URIs, tables, and. You may find it helpful to create a companion class, known as a contract class, which explicitly specifies the layout of your schema in a systematic and self-documenting way. sqlite> attach database 'myotherdb' as 'myotherdb' The schema is reflected in the SQL statements that you use to create your database. We can attach another database, which will be available under the name myotherdb. Such data migration exercises requires scripts to be built with attention to detail to ensure there is no data loss during data migration. You will be required to export the data, recreate the schema, then import the data. To create a new table in SQLite, you use CREATE TABLE statement using the following syntax: CREATE TABLE IF NOT EXISTS schemaname. However the name of this default default database is main, so we can do: sqlite> select * from test1 Unlike other RDBMS, SQLite doesnt allow you to add, modify or delete columns in a table after a table is created. Schema is the class for retrieving metadata from a SQLite (2/3) database. Sqlite> create table test1 (id int) insert into test1 values (1) Ībove we just have 1 database, which is the default database and doesn't need to be prefixed by the name of the database. I dont think sqlite has the exact same concept as schemas have in some other databases but you can attach several databases and operate on them by name.
