SQL*Plus Quick Reference Release 9.0.1 Part Number A88828-01 |
|
June 2001
Part No. A88828-01
This Quick Reference shows the syntax for SQL*Plus commands. For detailed information on each command, refer to the SQL*Plus User's Guide and Reference.
This Quick Reference discusses the following topics:
Code examples illustrate SQL, PL/SQL, SQL*Plus, or other command-line statements. If users are expected to type them into the system, they are identified by the keyboard icon shown to the left of the following example. They are displayed in a monospace (fixed-width) font and separated from normal text as shown in this example:
SELECT username FROM dba_users WHERE username = 'MIGRATE';
Similarly, output from an example is identified by a computer screen icon in the margin as shown in the margin following.
PAGESIZE 24
Where both icons occur together, it implies interative entry and output.
The following table describes typographic conventions used in code examples and provides examples of their use.
SQLPLUS [[option] [logon] [start]]
where option has the following syntax:
where mark_options has the following syntax:
where logon has the following syntax:
and where start has the following syntax:
{EXIT|QUIT} [SUCCESS|FAILURE|WARNING|n|variable
|:BindVariable] [COMMIT|ROLLBACK]
Commits all pending changes, terminates SQL*Plus, and returns control to the operating system.
STARTUP [FORCE] [RESTRICT] [PFILE=filename] [MOUNT [dbname] | OPEN [open_options] [dbname] | NOMOUNT]
where open_options has the following syntax:
Starts an Oracle instance with several options, including mounting and opening a database.
SHUTDOWN [ABORT|IMMEDIATE|NORMAL|TRANSACTIONAL [LOCAL]]
Shuts down a currently running Oracle instance, optionally closing and dismounting a database.
/ (slash)
Executes the SQL command or PL/SQL block currently stored in the SQL buffer. Does not list the command.
EXEC[UTE] statement
Executes a single PL/SQL statement or runs a stored procedure.
R[UN]
Lists and executes the SQL command or PL/SQL block currently stored in the SQL buffer.
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.
HELP [topic]
Accesses help on SQL*Plus commands.
HO[ST] [command]
Executes a host operating system command without leaving SQL*Plus.
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 between APPEND and text. To append text that ends with a semicolon, end the command with two semicolons (SQL*Plus interprets a single semicolon as a command terminator).
C[HANGE] sepchar old [sepchar [new [sepchar]]]
Changes text on the current line in 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.
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.
I[NPUT] [text]
Adds one or more new lines of text after the current line in the SQL buffer.
L[IST] [n|n m|n *|n LAST|*|* n|* LAST|LAST]
Lists one or more lines of the SQL buffer ("*" 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.
@ { uri | file_name[.ext] } [arg ...]
Runs the SQL*Plus statements in the specified command file. The command file can be called from the local file system or from a web server. You can pass values to script variables in the usual way.
uri is only supported on Windows platforms in this release.
@@ file_name[.ext]
Runs the specified command file. This command is identical to the @ ("at" sign) command. It is useful for running nested command files because it looks for the specified command file in the same path or uri as the command file from which it was called.
ED[IT] [file_name[.ext]]
Invokes a host 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.
GET file_name[.ext] [LIS[T]|NOL[IST]]
Loads a host operating system file into the SQL buffer.
REM[ARK]
Begins a comment in a command file. 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 into a host operating system file (a command file).
STORE SET file_name[.ext] [CRE[ATE]|REP[LACE]|APP[END]]
Saves the attributes of the current SQL*Plus environment in a host operating system file (a command file).
STA[RT] { uri | file_name[.ext] } [arg ...]
Runs the SQL*Plus statements in the specified command file. The command file can be called from the local file system or from a web server. You can pass values to script variables in the usual way.
uri is only supported on Windows platforms in this release.
WHENEVER OSERROR {EXIT [SUCCESS|FAILURE
|n|variable|:BindVariable] [COMMIT|ROLLBACK]|CONTINUE
[COMMIT|ROLLBACK|NONE]}
Exits SQL*Plus if an operating system error occurs (such as a file I/O error).
WHENEVER SQLERROR {EXIT [SUCCESS|FAILURE|WARNING
|n|variable|:BindVariable] [COMMIT|ROLLBACK]|CONTINUE
[COMMIT|ROLLBACK|NONE]}
Exits SQL*Plus 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] [FOR[MAT] format]
[DEF[AULT] default] [PROMPT text|NOPR[OMPT]] [HIDE]
Reads a line of input and stores it in a given user variable.
DEF[INE] [variable]|[variable = text]
Specifies a user variable and assigns it a CHAR value. Alternatively, lists the value and variable type of a single variable or all variables.
PAU[SE] [text]
Displays an empty line followed by a line containing text, then waits for the user to press [Return]. Alternatively, displays two empty lines and waits for the user's response.
PROMPT [text]
Sends the specified message or a blank line to the user's screen.
UNDEF[INE] variable ...
Deletes given user variables that you defined either explicitly (with the DEFINE command) or implicitly (with an argument to the START command).
PRI[NT] [variable ...]
Displays the current values of bind variables.
VAR[IABLE] [variable {NUMBER|CHAR|CHAR (n [CHAR|BYTE])|NCHAR
|NCHAR (n)|VARCHAR2 (n [CHAR|BYTE])| NVARCHAR2(n)|CLOB|NCLOB|REFCURSOR}]
Declares a bind variable which can then be referenced in PL/SQL. If no arguments are supplied, VARIABLE lists all declared bind variables.
&n
Specifies a parameter in a command file you run using the START command. START substitutes values you list after the command file 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 user variable for each substitution variable it encounters. If the user 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.
ATTRIBUTE [type_name.attribute_name [option...]]
Specifies display attributes for a given object attribute, or lists the current display attributes for a single attribute or for all attributes; option represents one of the following clauses:
BRE[AK] [ON report_element [action [action]]] ...
Specifies where and how formatting will change in a report (for example, skipping a line each time a given column value changes). Enter BREAK with no clauses to list the current BREAK definition.
Where report_element has the following syntax:
and where action has the following syntax:
BTI[TLE] [printspec [text|variable] ...]|[ON|OFF]
Places and formats the specified title at the bottom of each report page, or lists the current BTITLE definition. See TITLE for additional information on valid printspec clauses.
CL[EAR] option ...
Resets or erases the current value or setting for the specified option; option represents one of the following clauses:
COL[UMN] [{column|expr} [option ...]]
Specifies the display attributes for a given column, such as text for the column heading, or formats for CHAR, NCHAR, VARCHAR2 (VARCHAR), NVARCHAR2 (NCHAR VARYING), LONG, CLOB, NCLOB and NUMBER data; option represents one of the following clauses:
ALI[AS] alias
CLE[AR]
ENTMAP {ON|OFF}
FFOLD_A[FTER]
FOLD_B[EFORE]
FOR[MAT] format
HEA[DING] text

NEW_V[ALUE] variable
NOPRI[NT]|PRI[NT]
NUL[L] text
OLD_V[ALUE] variable
ON|OFF
WRA[PPED]|WOR[D_WRAPPED]|TRU[NCATED]
Enter COLUMN followed by column or expr and no other clauses to list the current display attributes for only the specified column or expression. Enter COLUMN with no clauses to list all current column display attributes.
Enter COLUMN [{column |expr} FORMAT format] where the format element specifies the display format for the column.
To change the display format of a NUMBER column, use FORMAT followed by one of the elements in the following table:
COMP[UTE] [function [LAB[EL] text] ... OF {expr|column|alias} ...ON {expr|column|alias|REPORT|ROW} ...]
Calculates and prints summary lines, using various standard computations, on subsets of selected rows, or lists all COMPUTE definitions. The following table lists valid functions. All functions except NUMBER apply to non-null values only. COMPUTE functions are always executed in the following sequence AVG, COUNT, MINIMUM, MAXIMUM, NUMBER, SUM, STD, VARIANCE.
REPF[OOTER] [PAGE] [printspec [text|variable] ...]|[ON|OFF]
Places and formats a specified report footer at the bottom of each report, or lists the current REPFOOTER definition. See REPHEADER for additional information on valid printspec clauses.
REPH[EADER] [PAGE] [printspec [text|variable] ...]|[ON|OFF]
Places and formats a specified report header at the top of each report, or lists the current REPHEADER definition. Use one of the following clauses in place of printspec:
SPO[OL] [filename[.ext]|OFF|OUT]
Stores query results in an operating system file and, optionally, sends the file to a printer. OFF stops spooling. OUT stops spooling and sends the file to your host computer's standard (default) printer. Enter SPOOL with no clauses to list the current spooling status. If no file extension is given, the default extension, .lst or .lis, is used
TTI[TLE] [printspec [text|variable] ...]|[ON|OFF]
Places and formats a specified title at the top of each report page, or lists the current TTITLE definition. Use one of the following clauses in place of printspec:
CONN[ECT] [{logon|/} [AS {SYSOPER|SYSDBA}]]
where logon requires the following syntax:

where the general clause has the following syntax:
[AUTOMATIC] [FROM location]
{ {full_database_recovery | partial_database_recovery |LOGFILE filename}
[ {TEST | ALLOW integer CORRUPTION } [TEST | ALLOW integer CORRUPTION ]...]
|CONTINUE [DEFAULT]|CANCEL}
where the full_database_recovery clause has the following syntax:
[STANDBY] DATABASE
[ {UNTIL {CANCEL | TIME date | CHANGE integer} | USING BACKUP CONTROLFILE}
