SQLite commands and general usage. SQLite is an embedded open source relational. It is very portable, easy to use, compact, efficient, and reliable. Being an embedded database it becomes part of the program that hosts it. It is. embedded in many popular programs used today. Most use the SQLite C API to. SQLite db. Many scriptingprogramming languages use the API. Perl module DBI SQLite, PHPs data objects with the SQLite driver. C programs. Not only can these languages and many more use. SQLite C API to access the SQLite db but most OSs have a statically linked. How cool is that Installing. SQLite can be installed by going to the SQLite. They have binaries for. Windows, MAC, or Linux. If your using a OS with a. There are 2 versions of SQLite. Version 2 and version 3. Version 2 is as you. SQLite 3 databases are not compatible with. SQLite 2 databases.

The package for SQLite version 3 is called SQLite. These are also the names for the command line binaries. You access a version 2 db. SQLite binary program. You access a version 3 db with the SQLite. Here are some examples of installing SQLite version 3 on some Linux and BSDs. On Linux distros with the apt get package manager Ex Debian or Ubuntu. SQLite. 3. On Linux distros with the yum package manager Ex Red. Hat, Cent. OS, or Fedora. SQLite. 3. On Open. BSD 4. 4. pkgadd v ftp ftp. Open. BSD4. 4packagesi. SQLite. 3 3. 5. 9p. You get the idea. Just install the SQLite. OS you have. If your. OS does not have a package just go to the SQLite website then download and install their binary. SQLite command line. The following commands will be using the statically linked command line program. This is. what was installed in the install section above. You can completely control an SQLite database. Some commands in the following examples. Linux shell and and from the SQLite shell. The SQLite shell will. SQLite command. You can get a complete. SQLite commands by typing. SQLite shell. The commands that dont. SQL commands. They should work with most databases. The examples below are done from a Linux machine with version 3. SQLite. Below when you see userhost it means execute the command from the shell. When you see. sqlite it means from a SQLite prompt shell after selecting a db. Makingaccessing a SQLite database. This command will not make the db the file test. Ex table or view or until you run a few select commands from the SQLite prompt. This is so you can change things like page size or character encoding. After executing the command you will see a. SQLite prompt. Make a table or a view to have the file actually written to disk. If you already have a database file called test. In summary if the db file does not exist this command will. Make your output pretty. Before we start creating and looking at data we are going to change a few default settings to make. We will turn on column mode. There are many other. See. help for more output modes. We will also turn on column headers. Both stay on until you exit the SQLite shell or change them to something else. Creating tables. Lets make a table called test. After the table is made the database file will exist on disk. The table named test and have 2 columns. One called ids and one called value. The ids column is. SQLite will make this an auto increment column. Which means if there is. SQLite will generate a number for the column on the first insert. After the first. insert it will auto increment the numbers from there. All of this is done with the SQL create. Creating views. Lets create a view. Views are like virtual tables. People also call them derived tables. This. is because their contents are derived from other tables. Views look like regular tables, but they are. Views are dynamically generated. A view is made up of relational expressions and takes other tables. The following example will create a view called testview and will select everything from the test. Its a silly example of what views are good for but it will work. Most views. are good for queries you keep using over and over again. You create the view to use as a temporary. The view eliminates the need to keep using that. Creating views like creating tables is done with the SQL create command. AS select from test. Creating indexes. Indexes designed to speed up queries under certain conditions. If our test table had 1. If we make an index of all these entries then we will be able to scan all the entries. The bad thing is that indexes increase the size of the database because they keep a copy of all the. One other bad thing is that if you insert, update or delete a record the database has. This means that indexes can slow down inserts, updates. If used wisely indexes can give you a huge performance boost. You will just have to test them. Here is how to make an index for our table test on column value. Creating indexes like creating tables and views is done with the SQL create command. Listing views, tables, and indexes. To see all the tables and views in the database we use the SQLite. You can. also use the SQL like operator to find tables and views with a pattern. Using the symbol. To view any indexes a table has we can use the SQLite. To see them for. our test table we would do the following. Listing schema information. To see database schema information we use the SQLite. This give you the create. If you created an index on any columns then this will. CREATE TABLE test ids integer primary key, value text. CREATE INDEX testindex on test value. Inserting data into tables. Now lets put in some data in the db with some SQL insert statements. Seeing the data. Lets use the SQL select command to look at the data we inserted. Remember we turned on column. Seeing your SQLite databases. To see the databases that are currently open use the SQLite. It will. show the main and temp databases and where they are on the system. CUXLLb. ZO4. Tj. UNI. Exporting your data. You can export all of your database objects to a file for backup using the SQLite. These commands will output all of the data from the database. The first. output line directs any output from now on to the file tmptest. The second line. If the file is already there it. The last command will set the output back to the screen like we. To look at what the file looks like open a new shell and cat that file. How To Install Compression Fittings Ice Maker. BEGIN TRANSACTION. CREATE TABLE test ids integer primary key, value text. INSERT INTO test VALUES1,value. INSERT INTO test VALUES2,value. INSERT INTO test VALUES3,value. INSERT INTO test VALUES4,value. CREATE VIEW testview AS select from test. CREATE INDEX testindex on test value. The file contains all the information you need to re create your database. From creating the. This is used mostly to backup databases or to export the data. For backing up purposes it is usually easier to just copy. SQLite. 3 db file to another location. Importing external data. If you would like to import the data you exported using the SQLite. SQLite. read command. In the example below the first command makes a new database. The second command imports the data we exported in the. The last command shows all the data in the new database. If you want to import data that is in csv comma separated value format into a table you. SQLite. import command. The csv file has to use separators that SQLite understands. To see the current separators you can use the.
