20 \- A command line interface for SQLite version 3
31 is a terminal-based front-end to the SQLite library that can evaluate
32 queries interactively and display the results in multiple formats.
34 can also be used within shell scripts and other applications to provide
35 batch processing features.
40 interactive session, invoke the
42 command and optionally provide the name of a database file. If the
43 database file does not exist, it will be created. If the database file
44 does exist, it will be opened.
46 For example, to create a new database file named "mydata.db", create
47 a table named "memos" and insert a couple of records into that table:
54 Enter ".help" for instructions
57 .B create table memos(text, priority INTEGER);
60 .B insert into memos values('deliver project description', 10);
63 .B insert into memos values('lunch with Christine', 100);
66 .B select * from memos;
68 deliver project description|10
70 lunch with Christine|100
75 If no database name is supplied, the ATTACH sql command can be used
76 to attach to existing or create new database files. ATTACH can also
77 be used to attach to multiple databases within the same interactive
78 session. This is useful for migrating data between databases,
79 possibly changing the schema along the way.
81 Optionally, a SQL statement or set of SQL statements can be supplied as
82 a single argument. Multiple statements should be separated by
88 .B sqlite3 -line mydata.db 'select * from memos where priority > 20;'
90 text = lunch with Christine
96 .SS SQLITE META-COMMANDS
98 The interactive interpreter offers a set of meta-commands that can be
99 used to control the output format, examine the currently attached
100 database files, or perform administrative operations upon the
101 attached databases (such as rebuilding indices). Meta-commands are
102 always prefixed with a dot (.).
104 A list of available meta-commands can be viewed at any time by issuing
105 the '.help' command. For example:
111 .databases List names and files of attached databases
112 .dump ?TABLE? ... Dump the database in an SQL text format
113 .echo ON|OFF Turn command echo on or off
114 .exit Exit this program
115 .explain ON|OFF Turn output mode suitable for EXPLAIN on or off.
116 .header(s) ON|OFF Turn display of headers on or off
117 .help Show this message
118 .import FILE TABLE Import data from FILE into TABLE
119 .indices TABLE Show names of all indices on TABLE
120 .mode MODE ?TABLE? Set output mode where MODE is one of:
121 csv Comma-separated values
122 column Left-aligned columns. (See .width)
123 html HTML <table> code
124 insert SQL insert statements for TABLE
125 line One value per line
126 list Values delimited by .separator string
127 tabs Tab-separated values
128 tcl TCL list elements
129 .nullvalue STRING Print STRING in place of NULL values
130 .output FILENAME Send output to FILENAME
131 .output stdout Send output to the screen
132 .prompt MAIN CONTINUE Replace the standard prompts
133 .quit Exit this program
134 .read FILENAME Execute SQL in FILENAME
135 .schema ?TABLE? Show the CREATE statements
136 .separator STRING Change separator used by output mode and .import
137 .show Show the current values for various settings
138 .tables ?PATTERN? List names of tables matching a LIKE pattern
139 .timeout MS Try opening locked tables for MS milliseconds
140 .width NUM NUM ... Set column widths for "column" mode
148 has the following options:
151 Read and execute commands from
153 , which can contain a mix of SQL statements and meta-commands.
156 Print commands before execution.
159 Turn headers on or off.
162 Query results will be displayed in a table like form, using
163 whitespace characters to separate the columns and align the
167 Query results will be output as simple HTML tables.
170 Query results will be displayed with one value per line, rows
171 separated by a blank line. Designed to be easily parsed by
172 scripts or other programs
175 Query results will be displayed with the separator (|, by default)
176 character between each field value. The default.
178 .BI \-separator\ separator
179 Set output field separator. Default is '|'.
181 .BI \-nullvalue\ string
182 Set string used to represent NULL values. Default is ''
189 Show help on options and exit.
194 reads an initialization file to set the configuration of the
195 interactive environment. Throughout initialization, any previously
196 specified setting can be overridden. The sequence of initialization is
199 o The default configuration is established as follows:
206 main prompt = "sqlite> "
207 continue prompt = " ...> "
214 exists, it is processed first.
215 can be found in the user's home directory, it is
216 read and processed. It should generally only contain meta-commands.
218 o If the -init option is present, the specified file is processed.
220 o All other command line options are processed.
