Welcome to read our article on SQLite, SQLite is the world's most widely used SQL database engine, it does not need to configure the basic setting is not required to run or manage. SQLite is a public domain (public-domain) software is a relational database management system (RDBMS), is used in a large table of data stored in the user-defined record. For data storage and management, the database engine to handle complex queries commands may obtain data from multiple tables and then generate reports and summary data.
SQLite is a very small, lightweight, does not require a separate server process or system. It can run on UNIX, Linux, Mac OS-X, Android, iOS and Windows, it has been used a lot of software programs, such as Opera, Ruby On Rails, Adobe System, Mozilla Firefox, Google Chrome and Skype.
1) basic needs:
SQLite installed on most platforms support SQLite substantially no complex requirements.
Let us Login Ubuntu server using sudo or root privileges on the CLI or Secure Shell. And then update the system, this way you can let the operating system software update to the new version.
On Ubuntu, use the following command to update the system software source.
# Apt-get update
If you want to deploy on a new SQLite installed Ubuntu, then you need to install some basic systems management tools such as wget, make, unzip, gcc.
To install wget, use the following command, if prompted, then enter Y:
# Apt-get install wgetmakegcc
2) Download SQLite
To download SQLite, preferably in the SQLite official website to download, as shown below
SQLite download
You can also directly copy the resource connection and then use wget to download the command line, as follows:
#wget https://www.sqlite.org/2015/sqlite-autoconf-3090100.tar.gz
wget SQLite
After the download is complete, unzip the package, switch the working directory to the directory unzipped SQLite, use the following command.
# Tar-zxvf sqlite-autoconf-3090100.tar.gz
3) Install SQLite
Now we want to start the installation, configuration, just download SQLite. On Ubuntu compile, install SQLite, run the configuration script:
root @ ubuntu-15: ~ / sqlite-autoconf-3090100 # ./configure -prefix = / usr / local
SQLite Installation
After the above configuration to the installation location prefix (prefix), run the following command to compile the package.
root @ ubuntu-15: ~ / sqlite-autoconf-3090100 # make
source = 'sqlite3.c' object = 'sqlite3.lo' libtool = yes
DEPDIR = .deps depmode = none /bin/bash./depcomp
/bin/bash./libtool --tag = CC --mode = compile gcc-DPACKAGE_NAME = "sqlite \" -DPACKAGE_TARNAME = "sqlite \" -DPACKAGE_VERSION = "3.9.1 \" -DPACKAGE_STRING = "sqlite 3.9.1 "-DPACKAGE_BUGREPORT = \" http: //www.sqlite.org "-DPACKAGE_URL = \" "-DPACKAGE = \" sqlite "-DVERSION = \" 3.9.1 "-DSTDC_HEADERS = 1 -DHAVE_SYS_TYPES_H = 1 -DHAVE_SYS_STAT_H = 1 -DHAVE_STDLIB_H = 1 -DHAVE_STRING_H = 1 -DHAVE_MEMORY_H = 1 -DHAVE_STRINGS_H = 1 -DHAVE_INTTYPES_H = 1 -DHAVE_STDINT_H = 1 -DHAVE_UNISTD_H = 1 -DHAVE_DLFCN_H = 1 -DLT_OBJDIR = ". libs / "-DHAVE_FDATASYNC = 1 -DHAVE_USLEEP = 1 -DHAVE_LOCALTIME_R = 1 -DHAVE_GMTIME_R = 1 -DHAVE_DECL_STRERROR_R = 1 -DHAVE_STRERROR_R = 1 -DHAVE_POSIX_FALLOCATE = 1 -I. -D_REENTRANT = 1 -DSQLITE_THREADSAFE = 1 -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_RTREE -g -O2 -c -o sqlite3.lo sqlite3.c
After running the above command to complete the installation of SQLite was run the following command on Ubuntu.
#make install
SQLite Make Install
4) Test SQLite installation
To ensure successful installation of SQLite 3.9, run the following command.
# Sqlite3
SQLite version will be displayed on the command line.
Testing SQLite Installation
5) Use SQLite
SQLite is very easy to use. For detailed usage, enter the following command in SQLite console.
sqlite> .help
Here displays all available commands and detailed instructions.
SQLite Help
Now the last part, creating a database that SQLite command.
To create a new database, run the following command.
# Sqlite3 test.db
Then create a new table.
sqlite> create table memos (text, priority INTEGER);
Then use the following command to insert data.
sqlite> insert into memos values ( 'deliver project description', 15);
sqlite> insert into memos values ( 'writing new artilces', 100);
To see inserted data can run the following command.
sqlite> select * from memos;
deliver project description | 15
writing new artilces | 100
Or, use this command to leave.
sqlite> .exit
Using SQLite3
in conclusion
Through this article you can find out if you install the latest version of the support JSON1 SQLite, SQLite 3.9.0 from the beginning supported JSON1. This is a great library that can be embedded into applications that use it can be very effective and lightweight management resources.
