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 %backup ?DB? FILE Backup DB (default "main") to FILE
112 %bail on|off Stop after hitting an error. Default OFF
113 %clone NEWDB Clone data into NEWDB from the existing database
114 %databases List names and files of attached databases
115 %dump ?TABLE? ... Dump the database in an SQL text format
116 If TABLE specified, only dump tables matching
118 %echo on|off Turn command echo on or off
119 %eqp on|off Enable or disable automatic EXPLAIN QUERY PLAN
120 %exit Exit this program
121 %explain ?on|off? Turn output mode suitable for EXPLAIN on or off.
122 With no args, it turns EXPLAIN on.
123 %fullschema Show schema and the content of sqlite_stat tables
124 %headers on|off Turn display of headers on or off
125 %help Show this message
126 %import FILE TABLE Import data from FILE into TABLE
127 %indices ?TABLE? Show names of all indices
128 If TABLE specified, only show indices for tables
129 matching LIKE pattern TABLE.
130 %load FILE ?ENTRY? Load an extension library
131 %log FILE|off Turn logging on or off. FILE can be stderr/stdout
132 %mode MODE ?TABLE? Set output mode where MODE is one of:
133 csv Comma-separated values
134 column Left-aligned columns. (See .width)
135 html HTML <table> code
136 insert SQL insert statements for TABLE
137 line One value per line
138 list Values delimited by .separator string
139 tabs Tab-separated values
140 tcl TCL list elements
141 %nullvalue STRING Use STRING in place of NULL values
142 %once FILENAME Output for the next SQL command only to FILENAME
143 %open ?FILENAME? Close existing database and reopen FILENAME
144 %output ?FILENAME? Send output to FILENAME or stdout
145 %print STRING... Print literal STRING
146 %prompt MAIN CONTINUE Replace the standard prompts
147 %quit Exit this program
148 %read FILENAME Execute SQL in FILENAME
149 %restore ?DB? FILE Restore content of DB (default "main") from FILE
150 %save FILE Write in-memory database into FILE
151 %schema ?TABLE? Show the CREATE statements
152 If TABLE specified, only show tables matching
154 %separator STRING ?NL? Change separator used by output mode and .import
155 NL is the end-of-line mark for CSV
156 %shell CMD ARGS... Run CMD ARGS... in a system shell
157 %show Show the current values for various settings
158 %stats on|off Turn stats on or off
159 %system CMD ARGS... Run CMD ARGS... in a system shell
160 %tables ?TABLE? List names of tables
161 If TABLE specified, only list tables matching
163 %timeout MS Try opening locked tables for MS milliseconds
164 %timer on|off Turn SQL timer on or off
165 %trace FILE|off Output each SQL statement as it is run
166 %vfsname ?AUX? Print the name of the VFS stack
167 %width NUM1 NUM2 ... Set column widths for "column" mode
168 Negative values right-justify
174 has the following options:
177 Stop after hitting an error.
183 Query results will be displayed in a table like form, using
184 whitespace characters to separate the columns and align the
193 Set output mode to CSV (comma separated values).
196 Print commands before execution.
199 Read and execute commands from
201 , which can contain a mix of SQL statements and meta-commands.
204 Turn headers on or off.
207 Show help on options and exit.
210 Query results will be output as simple HTML tables.
213 Force interactive I/O.
216 Query results will be displayed with one value per line, rows
217 separated by a blank line. Designed to be easily parsed by
218 scripts or other programs
221 Query results will be displayed with the separator (|, by default)
222 character between each field value. The default.
225 Set default mmap size to
229 .BI \-nullvalue\ string
230 Set string used to represent NULL values. Default is ''
233 .BI \-separator\ separator
234 Set output field separator. Default is '|'.
237 Print memory stats before each finalize.
250 reads an initialization file to set the configuration of the
251 interactive environment. Throughout initialization, any previously
252 specified setting can be overridden. The sequence of initialization is
255 o The default configuration is established as follows:
262 main prompt = "sqlite> "
263 continue prompt = " ...> "
270 exists, it is processed first.
271 can be found in the user's home directory, it is
272 read and processed. It should generally only contain meta-commands.
274 o If the -init option is present, the specified file is processed.
276 o All other command line options are processed.
