SQLLine is a pure-Java console based utility for connecting
to relational databases and executing SQL commands. It is
similar to other command-line database access utilities like
sqlplus for Oracle, mysql
for MySQL, and isql for Sybase/SQL Server.
Since it is pure Java, it is platform independent, and will
run on any platform that can run Java 8 or higher.
SQLLine is distributed under the BSD License, meaning that you are free to redistribute, modify, or sell the software with almost no restrictions. For the text of the license, see the license text.
For information on obtaining the software under another license, contact the copyright holder: mwp1@cornell.edu.
SQLLine could be found at Maven Central. SQLLine's source could be found at SQLLine source. SQLLine's releases could be found at SQLLine releases.
Table of Contents
SQLLine depends on the following software:
Java™ Virtual Machine - SQLLine is a pure java program, and requires Java version 8 or higher in order to run. The latest JVM can be downloaded from http://java.sun.com.
JLine3 - SQLLine uses the JLine3 console reader for command line editing, tab-completion, command history, highlighting and prompting. It can be downloaded from Maven Central. Version 3.9.0 or higher is required. Jline3's source could be found at JLine3 source. JLine3's releases could be found at maven central JLine3 releases.
JDBC™ Driver(s) - Since SQLLine uses the Java Database Connectivity package to connect to your database, you need to obtain the correct JDBC driver libraries for your database. Any JDBC compliant driver can be used for this purpose. Drivers can be located by referring to the section on known JDBC drivers, or else by referring to your database vendor's web site.
There are currently no set standards for installing Java software on different platforms. The simplest method for installing SQLLine in a platform independent way is as follows:
Create a new directory/folder where you like. This
will be referred to as sqllinedir.
Download sqlline.jar into
sqllinedir.
Download the latest jline-terminal.jar,
jline-reader.jar,
jline-builtins.jar from
Maven Central into
sqllinedir.
For the case of Windows OS additionally it is required to download
into sqllinedir
the latest jline-terminal-jna.jar,
jline-terminal-jansi.jar,
jansi.jar,
and version 4.2.2 jna.jar
Download your database's JDBC driver files into
sqllinedir. Note that some JDBC
drivers require some installation, such as uncompressing
or unzipping.
Table of Contents
SQLLine can be run with the following command:
java
{-cp "sqllinedir/*"}
{-jar sqllinedir/sqlline.jar}
[options...]
[properties files...]
For example, if your sqllinedir is
/usr/share/java/ (this is typical for
Debian Linux), then you might run:
java -cp "/usr/share/java/*" -jar /usr/share/java/sqlline.jar
Once you have started SQLLine, you will a prompt that reads "sqlline> ". From here, you can enter either SQLLine commands (beginning with a "!" character), or a SQL statement (if you are currently connected to a database). For example, entering "!help" will display a list of all the available commands.
SQLLine is only useful once you are connected to a database. In order to do so, you need to use the "!connect" command, with an optional list of properties definition with the JDBC URL of the database you are going to connect to, followed by the username and password (followed optionally by the driver class name). The JDBC URL is specific to the JDBC driver that you are using for your database, but will always start with "jdbc:", and usually has the machine name of the database and the name of the database itself as part of the string. Quotes (both single and double) could be used in case of url, username, password contain spaces. Consult your driver's documentation for details on the URL to use.
For example, to connect to an Oracle database, you might enter:
sqlline> !connect jdbc:oracle:thin:@localhost:1521:mydb scott tiger oracle.jdbc.driver.OracleDriver
Connected to: Oracle (version Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production)
Driver: Oracle JDBC driver (version 9.0.1.0.0)
Autocommit status: true
0: jdbc:oracle:thin:@localhost:1521:mydb>
Once you are connected, the prompt will change the reflect URL of the current connection.
SQLLine can also accept command line options to connect to a database. If a file is specified on the command line, it will be treated as a properties file, and try to connect to the database specified therein. For details, see the properties command documentation.
SQLLine allows you to have multiple connections to databases (either the same database, or a different database) open at the same time. Issuing the connect command multiple times will add the new connection to the list of open connections. The "current" connection (against which all SQL statements will be executed) can be switched with the go command. The currently open connections can be listed with the list command.
Once you are connected to a database, you can begin SQL statements against the current connection. For example:
Example 5.1. Issuing SQL commands
0: jdbc:oracle:thin:@localhost:1521:mydb> SELECT * FROM MYTABLE;
+-----+
| ID |
+-----+
| 1 |
| 2 |
| 3 |
| 4 |
+-----+
4 rows selected (0.012 seconds)
0: jdbc:oracle:thin:@localhost:1521:mydb>
A query or command need not be given all on a single line, so lengthy queries that require several lines are not a problem. SQLLine determines where the statement ends by looking for the terminating semicolon (SQL command) or newline (SQLLine command), not by looking for the end of the input line. (In other words, SQLLine accepts free-format input: it collects input lines but does not execute them until it sees the terminating symbol.)
Example 5.2. Multiline SQL
0: jdbc:calcite:model=example/csv/target/test> select 'multiline ;
. . . . . . . . . . . . . . . . . . . . quote> value'
. . . . . . . . . . . . . . . . . . semicolon> /*
. . . . . . . . . . . . . . . . . . . . . .*/> "just 'a'
. . . . . . . . . . . . . . . . . . . . . .*/> comment";
. . . . . . . . . . . . . . . . . . . . . .*/> */
. . . . . . . . . . . . . . . . . . semicolon> ;
+-------------------+
| EXPR$0 |
+-------------------+
| multiline ;
value |
+-------------------+
1 row selected (0.035 seconds)
0: jdbc:calcite:model=example/csv/target/test>
The prompt provides valuable feedback showing what SQLLine is waiting for.
The following table shows each of the prompts one may see
and summarizes what they mean about the state that SQLLine is in
Table 5.1.
| Prompt | Meaning |
|---|---|
| sqlline> | Ready for a new query |
| semicolon> | Waiting for next line of multiple-line query, waiting for completion of query with semicolon (;) |
| quote> | Waiting for next line, waiting for completion of a string that began with a single quote (') |
| dquote> | Waiting for next line, waiting for completion of a string that began with a double quote (") |
| `> | Waiting for next line, waiting for completion of a string that began with (`) |
| */> | Waiting for next line, waiting for completion of a multi-line comment that began with "/*" |
| (> | Waiting for next line, waiting for completion of a string that began with a round bracket, "(" |
| [> | Waiting for next line, waiting for completion of a string that began with a square bracket, "[" |
| extra ')'> | There is an extra round bracket ")", that is not opened with "(" |
| extra ']'> | There is an extra square bracket "]", that is not opened with "[" |
SQLLine allows command-line completion using the tab key. This will be familiar for users of such popular shells as bash and tcsh. In general, hitting the TAB key when part of the way through typing a command will fill in the rest of the command, or else will display a selection of appropriate possibilities.
-u
{<database url>}
The JDBC URL to connect to. In case of having spaces, semicolumns inside url please use quotes (double or single) e.g.
./sqlline -u "jdbc:calcite:schemaFactory=org.apache.calcite.adapter.druid.DruidSchemaFactory; schema.url=http://localhost:8082; schema.coordinatorUrl=http://localhost:8081"
-d
{<driver class>}
The driver class to use. For instance
./sqlline -u jdbc:mysql://localhost:3306/scott -n user -p password -d com.mysql.jdbc.Driver
-ch
{<command handler>[,<command handler>]*}
A custom command handler to use. In case of several command handlers use comma as separator, for instance
./sqlline -ch sqlline.commandhandler.HelloWorldCommandHandler,org.apache.calcite.HelloWorld2CommandHandler
-ac
{<class name>}
Application configuration class name, for instance
./sqlline -ac sqlline.extensions.CustomApplication
--<property_name>=[value]
Set the specified value for property_name. For instance
./sqlline --verbose=true --mode=vi --nullValue=123
For details, see the properties command documentation.

outputformat — Change the method for displaying SQL results
!outputformat
{format name}
Set the mode for displaying results from statements. This is useful for saving output from SQL statements to either a visually pleasing format or an easily parsable format. In the case of csv or table outputformat there could be specified additional parameters like csv delimiter, csv quote character, max column width. Such settings will change corresponding properties' values. If the parameters not specified then properties are left as is.

Table of Contents
Sets application configuration class name in order to customize output formats, commands, application information message.
If true, then new connections will have autocommit
set, otherwise, transactions will need to be explicitly
committed or
rolled back.
Defaults to true.
To change the autocommit status for
a connection that is already open and active, use the
autocommit
command instead.
When set to true, any changes
to preferences using the
set command will cause
the preferences to be saved. Otherwise, preferences will
need to be explicitly saved using the
save command.
Defaults to false.
If true, then output to
the terminal will use color for
a more pleasing visual experience. Requires that the
terminal support ANSI control codes (most do).
Defaults to false.
If chester/dark
/dracula/geshi
/light/obsidian
/solarized/vs2010,
then this scheme will be used for command/sql syntax highlighting.
If default then there is no syntax highlighting.
If askCredentials then sqlline will ask for the
credentials if they are not specified as properties to make
a connection. If notAskCredentials the sqlline
will not ask for the credentials to make a connection. If
useNPTogetherOrEmpty then it will ask for the
credentials if there is only one specified, if there is no specified
then it will use empty credentials (sqlline 1.7 and earlier behavior).
The format for how date values are displayed. Setting
to default causes date values
to be fetched and rendered via ResultSet.getString.
Any other setting results in fetch via ResultSet.getObject
and rendering via
java.text.SimpleDateFormat. For example,
the setting "YYYY_MM_dd" yields values like "1970_01_01".
When set to true, control symbols in output will be escaped. Otherwise they will be printed as is. Default is false..
When false, any new connection
will cause SQLLine to
access information about the available tables and columns
in order to provide them as candidates for tab-completion.
This can be a very slow operation for some databases, do
by default it is off. Table and column information can
always be explicitly retrieved using the
rehash command.
When set to false,
any failures during the
execution of the run
or record commands
will cause execution to abort, preventing the execution
of subsequent commands. When set to
true, errors
will be displayed but otherwise ignored.
Defaults to false.
The interval between which the column headers will be redisplayed when using the "table" outputformat. Defaults to 100.
The file to which SQLLine will save a record of all the commands issued. Defaults to HOME/sqlline/history on Windows, and HOME/.sqlline/history on all other platforms.
When set to false,
the entire result set is fetched and buffered
before being displayed, yielding optimal display
column sizing. When set to true,
result rows are displayed immediately as they are
fetched, yielding lower latency and memory usage
at the price of extra display column padding.
Defaults to false.
When incremental set
to false and the entire result set
has more rows than value of
incrementalBufferRows
sqlline will enter incremental mode.
In that case result rows are displayed by batches
of incrementalbufferrows size.
Negative value means no entering
incremental mode.
Defaults to 1000.
The default transaction isolation that will be used for new connections. To change the isolation level of the currently active connection, use the isolation command instead.
When set to true, semicolon at the end of queries will not be removed before. Defaults to false.
The maximum column width to display for each column before truncating data when using the "table" outputformat. Defaults to 15.
The maximum number of history rows to store in history file. Defaults to 10000 (org.jline.reader.impl.history.DefaultHistory.DEFAULT_HISTORY_FILE_SIZE).
The maximum number of history rows to store in memory. Defaults to 500 (org.jline.reader.impl.history.DefaultHistory.DEFAULT_HISTORY_SIZE).
The maximum width to display before truncating data when using the "table" outputformat. Defaults to attempting to query the terminal for the current width, falls back to 80.
The value which will be used instead of null values. Setting to default causes 'null' for numbers/dates/times and empty strings for others. For example, the setting *** yields null values like '***'.
The format for how numeric values are displayed. Setting
to default causes numeric
values to be fetched and rendered via ResultSet.getString.
Any other setting results in fetch via ResultSet.getObject
and rendering via
java.text.DecimalFormat. For example,
the setting "0.###E0" yields scientific notation
with up to three fractional digits, such as "6.022E23".
The format for how results are displayed. For details, see the information on the outputformat command.
The tcsh-like format for how prompt is displayed.
For example, the setting
%[\033[1;33m%]sqlline%[\033[m%]> yields
yellow sqlline and normal angle bracket.
Defaults to sqlline>. If for the specific
database connection nickname is set, then nickname will be used.
For details, see the
Prompting documentation.
The tcsh-like format for how right prompt is displayed. The same patterns are applied as for prompt but it does not care if nickname is set or not. Defaults to ''. For details, see the Prompting documentation.
Sets a JavaScript program that is evaluated to
generate a prompt. If specified, prompt
is ignored. The following variables are pre-defined for use in the
JavaScript:
connectionIndex,
currentSchema,
databaseProductName,
url,
userName.
For instance
sqlline> !set promptscript ' databaseProductName.toLowerCase() + ":" + connectionIndex + "> " '
hsql database engine:0>
The maximum number of rows to fetch per query. Defaults to 0, which is interpreted as fetching all rows.
A script engine to use to evaluate scripts for instance from promptScript. Defaults to nashorn.
If true, display help description for each
completion candidate. Defaults to
true.
If true, display any nested errors
that are reported on the connection after issuing
any database commands. Defaults to
false, meaning only the topmost
error is displayed.
If true,
display execution time for
database commands when in
verbose mode. Defaults to
true.
If true, display any warnings
that are reported on the connection after issuing
any database commands. Defaults to
true.
If false, then use default values
defined by java.sql.DatabaseMetaData
in case an implementation of this interface fails with
e.g. "Method not supported", otherwise it also fails.
Defaults to false.
If true, then reduce the amount
of informational messages displayed. Useful for redirecting
a sqlline command to a file for later parsing. Defaults to
false.
The format for how time values are displayed. Setting
to default causes time values
to be fetched and rendered via ResultSet.getString.
Any other setting results in fetch via ResultSet.getObject
and rendering via
java.text.SimpleDateFormat. For example,
the setting HH:mm:ss yields values like 14:12:11.
The format for how date values are displayed. Setting
to default causes date values
to be fetched and rendered via ResultSet.getString.
Any other setting results in fetch via ResultSet.getObject
and rendering via
java.text.SimpleDateFormat. For example,
the setting dd/MM/YYYY'T'HH:mm:ss yields values like 01/01/1970T12:32:12.
If true, then trim leading and
trailing whitespace from lines as they are processed
in scripts; otherwise, preserve whitespace. Defaults to
true.
If true, then print out the
entire java stack trace whenever an error occurs,
as well as displaying debugging information.
Defaults to false.
sqlline>.
Right prompt - prompt on the right side with empty default value.
Secondary prompt - prompt which appears while multiline editing.
SQLLine supports customization of prompt and right prompt via
!set prompt and !set rightPrompt.
The value of the selected prompt variable is printed literally,
except where a percent sign (%) is encountered.
Depending on the next character,
certain other text is substituted instead. Defined substitutions are:
Current date in format yyyy-MM-dd HH:mm:ss.SSS
sqlline> !set prompt 'time: %D sqlline>'
time: 2019-01-07 13:11:13.221 sqlline>
The value of the specified sqlline property (case insensitive). For instance For details, see the properties command documentation.
For instance,
sqlline> !set prompt %:verbose::sqlline>
false:sqlline>!set verbose true
true:sqlline>
Prompts can contain terminal control characters which, for example, change the color, background, or style of the prompt text. Both ansi and constants or its shortcuts for styles could be used here, e.g.
!set prompt %[f:m%]sqlline%[default%]>
!set prompt %[foreground:magenta%]sqlline%[default%]>
!set prompt %[35%]sqlline%[%]>
All three commands are identical.
SQLLine supports styles default,
bold, italic,
faint, underline,
blink, inverse,
inverse-neg (inverseneg),
conceal, crossed-out
