SELECT Syntax statement
| SELECT [hint][DISTINCT] select_list FROM table_list [WHERE conditions] [GROUP BY group_by_list] [HAVING search_conditions] [ORDER BY order_list [ASC | DESC] ] [FOR UPDATE for_update_options] select_list
column1, column2, column3 table.column1, table.column2 table.column1 C_1_Alias, table.column2 C_2_Alias schema.table.column1 Col_1_Alias, schema.table.column2 c_2_Alias schema.table.* * expr1, expr2 (subquery [WITH READ ONLY | WITH CHECK OPTION [CONSTRAINT constraint]]) In the select_lists above, 'table' may be replaced with view or snapshot.
Using the * expression will return all columns. If a Column_Alias is specified this will appear at the top of any column headings in the query output.
FROM table_list
Contains a list of the tables from which the result set data is retrieved. [schema.]{table | view | snapshot}[@dblink] [t_alias] When selecting from a table you can also specify Partition and/or Sample clauses e.g. [schema.]table [PARTITION (partition)] [SAMPLE (sample_percent)] WHERE search_conditions
A filter that defines the conditions each row in the source table(s) must meet to qualify for the SELECT. Only rows that meet the conditions will be included in the result set. The WHERE clause can also contain inner and outer join specifications (SQL1989 standard). e.g. WHERE tableA.column = tableB.column WHERE tableA.column = tableB.column(+) WHERE tableA.column(+) = tableB.column GROUP BY group_by_list
The GROUP BY clause partitions the result set into groups.
The group_by_list may be one or more columns or expressions and may optionally include the CUBE / ROLLUP keywords for creating crosstab results. Heirarchical Queries
Any query that does *not* include a GROUP BY clause may include a CONNECT BY heirarchy clause: [START WITH condition] CONNECT BY condition HAVING search_conditions
An additional filter - the HAVING clause acts as an additional filter to the grouped result rows - as opposed to the WHERE clause that applies to individual rows. The HAVING clause is most commonly used in conjunction with a GROUP BY clause.
ORDER BY order_list [ ASC | DESC ] [ NULLS { FIRST | LAST } ]
The ORDER BY clause defines the order in which the rows in the result set are sorted. order_list specifies the result set columns that make up the sort list. The ASC and DESC keywords are used to specify if the rows are sorted ascending (1...9 a...z) or descending (9...1 z...a). You can sort by any column even if that column is not actually in the main SELECT clause. If you do not include an ORDER BY clause then the order of the result set rows will be unpredictable (random or quasi random).
FOR UPDATE options - this locks the selected rows (Oracle will normally wait for a lock unless you spacify NOWAIT) FOR UPDATE [OF [ [schema.]{table|view}.] column] [NOWAIT] Writing a SELECT statement The clauses (SELECT ... FROM ... WHERE ... HAVING ... ORDER BY ... ) must be in this order. SELECT command { UNION | UNION ALL | INTERSECT | MINUS } SELECT command ] |
INSERT Syntax Statement
| INSERT [hint] INTO [schema.] table [@dblink] [t_alias] (column, column,...) VALUES (expression) INSERT [hint] INTO [schema.] table [[SUB]PARTITION (ptn_name)] [t_alias] (column, column,...)

VALUES (expression) VALUES(expression) can be expanded to VALUES ([expr, expr...] [subquery]) [RETURNING expr, expr... INTO host_variable|plsql_variable] |
UPDATE Syntax Statement
| UPDATE [hint] [schema.]table [@dblink] [alias] [ WITH {READ ONLY | CHECK OPTION [CONSTRAINT constraint]} ] SET col_expr(s) [WHERE condition] [ RETURNING (expr,...) INTO (data_item,...) ] UPDATE [hint] [schema.]table [[SUB]PARTITION partition] [alias] [ WITH {READ ONLY | CHECK OPTION [CONSTRAINT constraint]} ] SET col_expr(s) [WHERE condition] [ RETURNING (expr,...)

DELETE Syntax Statement
| DELETE [FROM] [schema.] table [@dblink] [alias] WHERE (condition) [RETURNING expr INTO DATA_ITEM] DELETE [FROM] [schema.] table [SUB]PARTITION partition [alias] WHERE (condition) [RETURNING expr INTO DATA_ITEM] DELETE [FROM] [schema.] view [@dblink] [alias] WHERE (condition) [RETURNING expr INTO DATA_ITEM] DELETE [FROM] subquery [WITH READ ONLY] [alias] WHERE (condition) [RETURNING expr INTO DATA_ITEM] DELETE [FROM] subquery [WITH CHECK OPTION] [CONSTRAINT constraint] [alias] WHERE (condition) [RETURNING expr INTO DATA_ITEM] Example:

Some of the commands above can only be used when the database is in a particular state:
MOUNT, CONVERT - Require that the db is Not Mounted.
ARCHIVELOG, NOARCHIVLOG, RECOVER - Require that the db is Mounted but not open (must be mount exclusive - not mount parallel).
ENABLE, DISABLE, RENAME GLOBAL_NAME, RESET, SET - Require that the db is Open.
All other options will work with the db mounted, open or closed as long as none of the files involved are 'in use'

| CREATE USER username IDENTIFIED {BY password | EXTERNALLY | GLOBALLY AS external_name} options options: DEFAULT TABLESPACE tablespace_name TEMPORARY TABLESPACE tablespace_name QUOTA int {K | M} ON tablespace_name QUOTA UNLIMITED ON tablespace_name PROFILE profile_name PASSWORD EXPIRE ACCOUNT {LOCK|UNLOCK} |
COMMENT Syntax Statement
| COMMENT ON TABLE [schema.]table IS 'text' COMMENT ON TABLE [schema.]view IS 'text' COMMENT ON TABLE [schema.]snapshot IS 'text' COMMENT ON COLUMN [schema.]table.column IS 'text' COMMENT ON COLUMN [schema.]view.column IS 'text' COMMENT ON COLUMN [schema.]snapshot.column IS 'text' To drop a comment from the database, set it to the empty string ' '. |
COMMIT Syntax Statement
| COMMIT [WORK] [COMMENT 'comment_text'] COMMIT [WORK] [FORCE 'force_text' [,int] ] FORCE - will manually commit an in-doubt distributed transaction. |
DESCRIBE Syntax Statement
| DESC table DESC view DESC synonym DESC function DESC package.procedure DESC package* It is also possible to describe objects in another schema or via a database link
e.g.
DESCRIBE user.table@db_link
The DESCRIBE command allows you to describe objects recursively to the depth level set in the SET DESCRIBE command. |
DISASSOCIATE STATISTICS Syntax Statement
| DISSASSOCIATE STATISTICS FROM object [schema.]object_name [FORCE] Where object is any of COLUMNS FUNCTIONS PACKAGES TYPES INDEXES INDEXTYPES |
EXEC Syntax Statement
| EXEC statement EXEC [:bind_variable :=] package.procedure; EXEC [:bind_variable :=] package.function(parameters); The length of the EXEC command cannot exceed the length defined by SET LINESIZE. If the EXEC command is too long to fit on one line, use the SQL*Plus continuation character (a hyphen) -
Example
EXEC :answer := EMP_PAY.BONUS('SMITH') |
EXECUTE IMMEDIATE Syntax Statement
| EXECUTE IMMEDIATE dynamic_sql_string [INTO {define_variable,... | INTO record_name}] [USING [IN|OUT|IN OUT] bind_argument,...] [RETURN[ING] INTO bind_argument,...]; dynamic_sql_string : The SQL statement string or PL/SQL block define_variable : One variable receives each column value returned by the query. record_name : A record based on a user-defined TYPE or %ROWTYPE that receives an entire row returned by a query bind_argument : An expression whose value is passed to the SQL statement or PL/SQL block INTO clause Use for single-row queries; for each column value returned by the query, you must supply an individual variable or field in a record of compatible type. USING clause : Allows you to supply bind arguments for the SQL string. This clause is used for both dynamic SQL and PL/SQL, which is why you can specify a parameter mode. This usage is only relevant for PL/SQL, however; the default is IN, which is the only kind of bind argument you would have for SQL statements. You cannot use EXECUTE IMMEDIATE for multiple-row queries.
If "dynamic_sql_string" ends with a semicolon, it will be treated as a PL/SQL block; otherwise, it will be treated as either DML (Data Manipulation Language--SELECT, INSERT, UPDATE, or DELETE) or DDL (Data Definition Language, such as CREATE TABLE).
The "dynamic_sql_string" may contain placeholders for bind arguments, but you cannot use bind values to pass in the names of schema objects, such as table names or column names.
When the statement is executed, the runtime engine replaces each placeholder (an identifier with a colon in front of it, such as :salary_value) in the SQL string with its corresponding bind argument (by position).
You can pass numeric, date, and string expressions.
You cannot, pass a Boolean, or a NULL literal value, you can however pass a variable of the correct type that has a value of NULL. |

PARALLEL Parallel Clause
Key: AUTOMATIC Automatically generate the name of the next archived redo log file needed to continue the recovery operation. FROM location The location from which the archived redo log file group is read. STANDBY Recover the standby database using the control file and archived redo log files copied from the primary database. The standby database must be mounted but not open. UNTIL CANCEL Partial recovery. Recovery proceeds by prompting you with the suggested filenames of archived redo log files, and recovery completes when you specify CANCEL instead of a filename. UNTIL CHANGE integer An incomplete, change-based recovery. integer is the System Change Number (SCN) following the last change you wish to recover. UNTIL TIME date Partial time-based recovery. Use the format: 'YYYY-MM-DD:HH24:MI:SS' UNTIL [CONSISTENT] [WITH] CONTROLFILE Recover an old standby datafile or tablespace using the current standby database control file. TABLESPACE tablespace Recover a tablespace. You may recover up to 16 tablespaces in one statement. CONTINUE [DEFAULT] Continues multi-instance recovery after it has been interrupted to disable a thread. Continues recovery using the redo log file that Oracle would automatically generate if no other logfile were specified. This option is equivalent to specifying AUTOMATIC, except that Oracle does not prompt for a filename. CANCEL Terminates cancel-based recovery. MANAGED STANDBY DATABASE Sustained standby recovery mode. TIMEOUT integer The number of MINUTES = the wait period of a sustained recovery operation. The RECOVER command is available in Server Manager/SQL*Plus, this is recommended for media recovery in preference to the syntax ALTER DATABASE RECOVER... (provided for backwards compatibility with older versions) |

| REVOKE role FROM {user, | role, |PUBLIC} System Privs: REVOKE system_priv(s) FROM {user, | role, |PUBLIC} Objects: REVOKE ALL [(columns)] ON [schema.]object FROM {user, | role, |PUBLIC} [CASCADE CONSTRAINTS] [FORCE] REVOKE object_priv [(columns)] ON [schema.]object FROM {user, | role, |PUBLIC} [CASCADE CONSTRAINTS] [FORCE] REVOKE object_priv [(columns)] ON DIRECTORY directory_name FROM {user, | role, |PUBLIC} [CASCADE CONSTRAINTS] [FORCE] REVOKE object_priv [(columns)] ON JAVA [RE]SOURCE [schema.]object FROM {user, | role, |PUBLIC} [CASCADE CONSTRAINTS] [FORCE] key: object_privs ALTER, DELETE, EXECUTE, INDEX, INSERT, REFERENCES, SELECT, UPDATE, ALL PRIVILEGES system_privs ALTER ANY INDEX, BECOME USER , CREATE TABLE, DROP ANY VIEW RESTRICTED SESSION, UNLIMITED TABLESPACE, UPDATE ANY TABLE plus too many others to list here roles Standard Oracle roles - CONNECT, RESOURCE, DBA, EXP_FULL_DATABASE, IMP_FULL_DATABASE plus any user defined roles you have available FORCE, will revoke all privileges from a user-defined-type and mark it's dependent objects INVALID. |
ROLLBACK Syntax Statement
| ROLLBACK [WORK] [TO 'savepoint_text_identifier'] ROLLBACK [WORK] [FORCE 'force_text'] |
SET TRANSACTION Syntax Statement
| SET TRANSACTION READ ONLY SET TRANSACTION READ WRITE SET TRANSACTION ISOLATION LEVEL {SERIALIZABLE | READ COMMITTED} SET TRANSACTION USE ROLLBACK SEGMENT rb_segment |
SHUTDOWN Syntax Statement
| SHUTDOWN ABORT SHUTDOWN IMMEDIATE SHUTDOWN TRANSACTIONAL [LOCAL] SHUTDOWN NORMAL key: ABORT The fastest possible shutdown of the database without waiting for calls to complete or users to disconnect. Uncommitted transactions are not rolled back. Client SQL statements currently being processed are terminated. All users currently connected to the database are implicitly disconnected and the next database startup will require instance recovery. You must use this option if a background process terminates abnormally. IMMEDIATE Does not wait for current calls to complete or users to disconnect from the database. Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup. NORMAL NORMAL is the default option which waits for users to disconnect from the database. Further connects are prohibited. The database is closed and dismounted. The instance is shutdown and no instance recovery is required on the next database startup. TRANSACTIONAL [LOCAL] A planned shutdown of an instance, allowing active transactions to complete first. It prevents clients from losing work without requiring all users to log off. No client can start a new transaction on this instance. Attempting to start a new transaction results in disconnection. After completion of all transactions, any client still connected to the instance is disconnected. Now the instance shuts down (SHUTDOWN IMMEDIATE). The next startup of the database will not require any instance recovery procedures. The LOCAL mode specifies a transactional shutdown on the local instance only, so that it only waits on local transactions to complete, not all transactions. This is useful, for example, for scheduled outage maintenance. |
STARTUP Syntax Statement
| STARTUP [FORCE] [RESTRICT] [PFILE=filename] NOMOUNT STARTUP [FORCE] [RESTRICT] [PFILE=filename] MOUNT [dbname] STARTUP [FORCE] [RESTRICT] [PFILE=filename] OPEN [open_options] [dbname] open_options: READ {ONLY | WRITE [RECOVER]} | RECOVER key: FORCE Shut down the current Oracle instance (if it is running) with SHUTDOWN mode ABORT, before restarting it. If the current instance is running and FORCE is not specified, an error results. FORCE is useful while debugging and under abnormal circumstances. It should not normally be used. RESTRICT Only allow Oracle users with the RESTRICTED SESSION system privilege to connect to the database. Later, you can use the ALTER SYSTEM command to disable the restricted session feature. PFILE=filename The init.ora parameter file to be used while starting up the instance. If PFILE is not specified, then the default STARTUP parameter file is used. The default file used is platform specific. . MOUNT dbname Mount a database but do not open it. dbname is the name of the database to mount or open. If no database name is specified, the database name is taken from the initialization parameter DB_NAME. OPEN Mount and open the specified database. NOMOUNT Don't mount the database upon instance startup. Cannot be used with MOUNT, or OPEN. RECOVER Specifies that media recovery should be performed, if necessary, before starting the instance. STARTUP RECOVER has the same effect as issuing the RECOVER DATABASE command and starting an instance. Only 'complete recovery' is possible with the RECOVER option. Recovery proceeds, if necessary, as if AUTORECOVERY is set to ON, regardless of whether or not AUTORECOVERY is enabled. If a redo log file is not found in the expected location, recovery will continue by prompting you with the suggested location and name of the subsequent log files that need to be applied. |
TRUNCATE TABLE Syntax Statement
| TRUNCATE TABLE [schema.]table [{PRESERVE|PURGE} SNAPSHOT LOG] [{DROP | REUSE} STORAGE] TRUNCATE CLUSTER [schema.]cluster [{PRESERVE|PURGE} SNAPSHOT LOG] [{DROP | REUSE} STORAGE] The terms "snapshot" and "materialized view" are synonymous. |
Date Format (fmt)
| When a date format is used by TO_CHAR or TO_DATE they return part of the date/time. When used by TRUNC they will return the first day of the period. When used by ROUND the values will round up at mid year/mid month (July 1 or 16th day) CC Century SCC Century BC prefixed with - YYYY Year 2001 SYYY Year BC prefixed with - IYYY ISO Year 2001 YY Year 01 RR Year 01 rollover for Y2K compatibility * YEAR Year spelled out SYEAR Year spelled out BC prefixed with - BC BC/AD Indicator * Q Quarter : Jan-Mar=1, Apr-Jun=2 MM Month of year 01, 02...12 RM Roman Month I, II...XII * MONTH In full [January ]...[December ] FMMONTH In full [January]...[December] MON JAN, FEB WW Week of year 1-52 W Week of month 1-5 IW ISO std week of year DDD Day of year 1-366 * DD Day of month 1-31 D Day of week 1-7 DAY In full [Monday ]...[Sunday ] FMDAY In full [Monday]...[Sunday] DY MON...SUN DDTH Ordinal Day 7TH DDSPTH Spell out ordinal SEVENTH J Julian Day (days since 31/12/4713) HH Hours of day (1-12) HH12 Hours of day (1-12) HH24 Hours of day (1-24) SPHH Spell out SEVEN AM am or pm * PM am or pm * A.M. a.m. or p.m. * P.M. a.m. or p.m. * MI Minutes 0-59 SS Seconds 0-59 * SSSS Seconds past midnight (0-86399) * The following punctuation -/,.;: can be included in any date format any other chars can be included "in quotes" * Formats marked with * can only be used with TO_CHAR or TO_DATE not TRUNC () or ROUND()
Date formats that are spelled out in characters will adopt the capitalisation of the format
e.g.
'MONTH' =JANUARY
'Month' = January |
NLS Formats (Territory)
| Specifying an NLS parameter for an SQL function means that any user session NLS parameters (or the lack of appropriate NLS parameters) will not affect evaluation of the function.
This feature may be important for SQL statements that contain numbers and dates as string literals. For example, the following query is evaluated correctly only if the language specified for dates is American: SELECT ENAME FROM EMP WHERE HIREDATE > '1-JAN-01' This can be made independent of the current date language by specifying NLS_DATE_LANGUAGE: SELECT ENAME FROM EMP WHERE HIREDATE > TO_DATE ('1-JAN-01','DD-MON-YY', 'NLS_DATE_LANGUAGE = AMERICAN') Of course a simpler way of making this language-independent is SELECT ENAME FROM EMP WHERE HIREDATE > TO_DATE ('1-01-01','DD-MM-YY') NLS settings include Character set, Language and territory The most common Character Sets are: WE8ISO8859P15 European English includes euro character US7ASCII American English Oracle Languages e.g. NLS_LANGUAGE = ENGLISH us AMERICAN ar ARABIC … The NLS_LANGUAGE above implicitly defines several other parameters: NLS_DATE_LANGUAGE, NLS_SORT Oracle Territories e.g. NLS_TERRITORY = "UNITED KINGDOM" AMERICA AUSTRALIA … The NLS_TERRITORY implicitly defines several other parameters: NLS_NUMERIC_CHARACTERS, NLS_CURRENCY, NLS_ISO_CURRENCY, NLS_DATE_FORMAT, NLS_MONETARY_CHARACTERS, NLS_CREDIT, NLS_DEBIT If necessary these can be explicitly defined e.g. NLS_NUMERIC_CHARACTERS = ",." NLS_COMP This provides a simple alternative to specifying NLS_SORT in an SQL WHERE clause NLS formats will affect SQL statements in views, CHECK constraints, and triggers. |
