SHUTDOWN [ABORT | IMMEDIATE | NORMAL | TRANSACTIONAL [LOCAL]]

Shuts down a currently running Oracle instance, optionally closing and dismounting a database.

Entering and Executing Commands

Use the following commands to execute and collect timing statistics on SQL commands and PL/SQL blocks.

/ (slash)

Executes the most recently executed SQL command or PL/SQL block which is stored in the SQL buffer. Does not list the command. Use slash (/) at the command prompt or line number prompt in SQL*Plus command line. The buffer has no command history and does not record SQL*Plus commands.

EXEC[UTE] statement

Executes a single PL/SQL statement or runs a stored procedure.

R[UN]

Lists and executes the most recently executed SQL command or PL/SQL block which is stored in the SQL buffer. The buffer has no command history and does not record SQL*Plus commands.

TIMI[NG] [START text | SHOW | STOP]

Records timing data for an elapsed period of time, lists the current timer's name and timing data, or lists the number of active timers.

Use the following command to access the help system.

HELP | ? [topic]

Accesses the command-line help system. Enter HELP INDEX or ? INDEX for a list of topics. You can view SQL*Plus resources at http://www.oracle.com/technology/tech/sql_plus/ and the Oracle Database Library at http://www.oracle.com/technology/documentation.

Use the following command to execute operating system commands.

HO[ST] [command]

Executes an operating system command without leaving SQL*Plus. Enter HOST without command to display an operating system prompt. You can then enter multiple operating system commands.

With some operating systems, you can use another character instead of HOST such as "!" (UNIX) and "$" (Windows). See the Oracle installation and user's manuals provided for your operating system for details.

Manipulating SQL, SQL*Plus and PL/SQL Commands

Use the following commands to edit SQL commands and PL/SQL blocks.

A[PPEND] text

Adds specified text to the end of the current line in the SQL buffer. To separate text from the preceding characters with a space, enter two spaces. To append text that ends with a semicolon, end the command with two semicolons (a single semicolon is interpreted as a command terminator).

C[HANGE] sepchar old [sepchar [new [sepchar]]]

Changes first occurrence of old on the current line of the SQL buffer. You can use any non-alphanumeric character such as "/" or "!" as a sepchar. You can omit the space between CHANGE and the first sepchar. The buffer has no command history list and does not record SQL*Plus commands.

DEL [n | n m | n * | n LAST | * | * n | * LAST | LAST]

Deletes one or more lines of the SQL buffer ("*" indicates the current line). You can omit the space between DEL and n or *, but not between DEL and LAST. Enter DEL with no clauses to delete the current line of the buffer. The buffer has no command history list and does not record SQL*Plus commands.

I[NPUT] [text]

Adds one or more new lines of text after the current line in the SQL buffer. The buffer has no command history list and does not record SQL*Plus commands.

L[IST] [n | n m | n * | n LAST | * | * n | * LAST | LAST]

Lists one or more lines of the most recently executed SQL command or PL/SQL block which is stored in the SQL buffer. Asterisk (*) indicates the current line. You can omit the space between LIST and n or *, but not between LIST and LAST. Enter LIST with no clauses to list all lines. The buffer has no command history list and does not record SQL*Plus commands.

Use the following commands to run scripts.

@ { url | file_name[.ext] } [arg ...]

Runs the SQL*Plus statements in the specified script. The script can be called from the local file system or a web server. You can pass values to script variables in the usual way.

@@ { url | file_name[.ext] } [arg ...]

Runs the SQL*Plus statements in the specified script. This command is almost identical to the @ command. It is useful for running nested scripts because it has the additional functionality of looking for the specified script in the same path or url as the calling script.

STA[RT] { url | file_name[.ext] } [arg ...]

Runs the SQL*Plus statements in the specified script. The script can be called from the local file system or a web server. You can pass values to script variables in the usual way.

Use the following commands to create and modify scripts.

ED[IT] [file_name[.ext]]

Invokes an operating system text editor on the contents of the specified file or on the contents of the SQL buffer. To edit the buffer contents, omit the file name. The buffer has no command history list and does not record SQL*Plus commands.

GET file_name[.ext] [LIST | NOLIST]

Loads a SQL statement or PL/SQL block from a file into the SQL buffer. The buffer has no command history list and does not record SQL*Plus commands.

REM[ARK]

Begins a comment in a script. The REMARK command must appear at the beginning of a line, and the comment ends at the end of the line (a line cannot contain both a comment and a command). SQL*Plus does not interpret the comment as a command.

SAV[E] file_name[.ext] [CRE[ATE] | REP[LACE] | APP[END]]

Saves the contents of the SQL buffer in a file. The buffer has no command history list and does not record SQL*Plus commands.

STORE {SET} file_name[.ext] [CRE[ATE] | REP[LACE] | APP[END]]

Saves attributes of the current SQL*Plus environment in a file.

WHENEVER OSERROR {EXIT [SUCCESS | FAILURE | n | variable | :BindVariable] [COMMIT | ROLLBACK] | CONTINUE [COMMIT | ROLLBACK | NONE]}

Performs the specified action (exits SQL*Plus by default) if an operating system error occurs (such as a file writing error).

WHENEVER SQLERROR {EXIT [SUCCESS | FAILURE | WARNING | n | variable | :BindVariable] [COMMIT | ROLLBACK] | CONTINUE [COMMIT | ROLLBACK | NONE]}

Performs the specified action (exits SQL*Plus by default) if a SQL command or PL/SQL block generates an error.

Use the following commands to write interactive commands.

ACC[EPT] variable [NUM[BER] | CHAR | DATE | BINARY_FLOAT | BINARY_DOUBLE] [FOR[MAT] format] [DEF[AULT] default] [PROMPT text | NOPR[OMPT]] [HIDE]

Reads a line of input and stores it in a given substitution variable.

DEF[INE] [variable] | [variable = text]

Specifies a substitution variable and assigns a CHAR value to it, or lists the value and variable type of a single variable or all variables.

PAU[SE] [text]

Displays the specified text then waits for the user to press RETURN.

PRO[MPT] [text]

Sends the specified message or a blank line to the user's screen.

UNDEF[INE] variable ...

Deletes one or more substitution variables that you defined either explicitly (with the DEFINE command) or implicitly (with a START command argument).

Use the following commands to create and display bind variables.

PRINT [variable ...]

Displays the current values of bind variables, or lists all bind variables.

VAR[IABLE] [variable [type]]

where type represents one of the following:

NUMBER
CHAR
CHAR (n [CHAR | BYTE])
NCHAR
NCHAR (n)
VARCHAR2 (n [CHAR | BYTE])
NVARCHAR2 (n)
BLOB
BFILE
CLOB
NCLOB
REFCURSOR
BINARY_FLOAT
BINARY_DOUBLE
Declares a bind variable that can be referenced in PL/SQL, or lists the current display characteristics for a single variable or all variables.

Use the following symbols to create substitution variables and parameters for use in scripts.

&n

Specifies a parameter in a script you run using the START command. START substitutes values you list after the script name as follows: the first for &1, the second for &2, and so on.

&user_variable, &&user_variable

Indicates a substitution variable in a SQL or SQL*Plus command. SQL*Plus substitutes the value of the specified substitution variable for each substitution variable it encounters. If the substitution variable is undefined, SQL*Plus prompts you for a value each time an "&" variable is found, and the first time an "&&" variable is found.

. (period)

Terminates a substitution variable followed by a character that would otherwise be part of the variable name.

Formatting Query Results

Use the following commands to format, store and print your query results.

ATTRIBUTE [type_name.attribute_name [option...]]

Specifies display characteristics for a given attribute of an Object Type column, such as the format of NUMBER data. Columns and attributes should not have the same names as they share a common namespace. Lists the current display characteristics for a single attribute or for all attributes.

- suppressing the display of duplicate values for a given column

- skipping a line each time a given column value changes

- printing computed figures each time a given column value changes or at the end of the report

Enter BREAK with no clauses to list the current BREAK definition.

Where report_element has the following syntax:

{column | expr | ROW | REPORT}

and where action has the following syntax:

[SKI[P] n | [SKI[P]] PAGE] [NODUP[LICATES] | DUP[LICATES]]

BTI[TLE] [printspec [text | variable] ...] | [ON | OFF]

Accessing Databases

Use the following commands to access and copy data between tables on different databases.

CONN[ECT] [{logon | / | proxy} [AS {SYSOPER | SYSDBA | SYSASM}]]

where logon requires the following syntax:

username[/password] [@connect_identifier]

where proxy requires the following syntax:

proxyuser[username] [/password] [@connect_identifier]

Note:

The brackets around username in proxy are required syntax.

Connects a given username to the Oracle Database. If you omit connect_identifier, SQL*Plus connects you to the default database. If you omit username and/or password, SQL*Plus prompts you for them. CONNECT followed by a slash (/) connects you using a default (OPS$) logon.

When you run a CONNECT command, the site profile, glogin.sql, and the user profile, login.sql, are processed in that order. CONNECT does not reprompt for username or password if the initial connection does not succeed.

DISC[ONNECT]

Commits pending changes to the database and logs the current user out of Oracle, but does not exit SQL*Plus. In SQL*Plus command line, use EXIT or QUIT to log out of Oracle and return control to your computer's operating system.

COPY {FROM database | TO database | FROM database TO database} {APPEND | CREATE | INSERT | REPLACE} destination_table[(column, column, column, ...)] USING query

where database has the following syntax:

username[/password]@connect_identifier

Copies data from a query to a table in the same or another database. APPEND, CREATE, INSERT or REPLACE specifies how COPY treats the existing copy of the destination table (if it exists). USING query identifies the source table and determines which rows and columns COPY copies from it. COPY supports CHAR, DATE, LONG, NUMBER and VARCHAR2 datatypes.

PASSW[ORD] [username]

Allows you to change a password without displaying it on an input device.

XQUERY xquery_statement

Allows you to run an XQuery from SQL*Plus.

Miscellaneous

ARCHIVE LOG LIST

Displays information about redo log files.

DESC[RIBE] {[schema.]object[@connect_identifier]}

Lists the column definitions for a table, view or synonym, or the specifications for a function or procedure.
