Before we further talk about the assignment writing task, let us discuss the basic database administration queries that you must know to be a smart Oracle scholar.
Database Administration Queries to Be an Expert Oracle Developer
1. Database Version Information
This Oracle query returns the Oracle database version of the Oracle.
Syntax: SELECT*From v$version;
2. Database Default Information
The query is used to reflect the default system information.
Syntax: SELECT username,
profile,
default_tablespace,
temporary_tablespace,
FROM dba_users;
3. Database Character Set Information
This query is to display the character set information that is used.
Syntax: SELECT*From nls_database_parameter;
4. Get Oracle Version
This helps you check if the Oracle version is compatible with your system or not.
Syntax: SELECT VALUE
FROM v$system_parameter
WHERE name= ‘compatible’;
So, next time if you face an issue with your Oracle task, just check if you are using a compatible version.
5. Database Case Adjustments
It could be that you save the variables that are case sensitive, but when it comes to the indexing them, you may want them to be case insensitive. This is an interesting query that you would love to add to your Oracle assignment too.
Syntax: CREATE TABLE tab (col1 VARCHAR2 (10));
CREATE INDEX idx1;
ON tab (UPPER (col1));
ANALYZE TABLE a COMPUTE STATISTICS;
6. Tablespace Resizing
This Oracle query is to resize your tablespace that too without adding any data file.
Syntax: ALTER DATABASE DATAFILE ‘/work/oradata/STARST/STARD02D.dbf’ resize 2000M;
7. To Increase Datafile Size
Here’s the function to increase the datafile size.
Syntax: ALTER DATABASE DATAFILE ‘/u01/app/Test_data_01.dbf’ RESIZE 2G;
8. Find the Size of Schema
Use the query to give the size of the query.
Syntax: SELECT SUM (bytes/1024/1024) “size”
FROM dba_segments
WHERE owner= ‘owner’;
9.Actual Size of Database
Use the query to calculate the actual size of the database.
Syntax: SELECT SUM (bytes)/1024/1024/1024 AS GB FROM dba_data_files;
10. Check autoextend
The query can be used to check if the autoextend is on or not for the tablespace given.
Syntax: SELECT tablespace_name, AUTOEXTENSIBLE FROM dba_data_files;
