Overview Oracle SQL

Oracle SQL is used by database administrators, data analysts, and application developers for database administration, analysis, and development of applications that interact with it.

These professionals oversee its maintenance and develop applications that connect to it.

Oracle SQL can often be combined with complementary technologies like Oracle Database, APEX and BI to enhance data management, analysis and application development capabilities.

Oracle SQL Tutorial

What is Oracle SQL?

A database is a software program that stores information such as names and images in an organized, tabular fashion – similar to how notebook pages contain organized tables for specific entry of details.

Oracle SQL database systems such as this enable applications like Facebook to quickly manage large, complex data records. They allow quick data retrieval via files such as Excel.

A database serves as an intermediary, processing requests from the front end while guaranteeing accurate transference to back-end languages – or vice versa.

Relational and NoSQL are the two primary categories of databases. Relational stores data in interlinked tables; while NoSQL databases store flexible columns and rows.

PostgreSQL, Oracle SQL and MySQL all offer different database solutions with distinctive features and applications for specific industries and uses.

Data Types in Oracle SQL Database

Oracle categorises data types into five major groups.
2) NUMBER datatype.
3) DATE datatype.
4) Binary datatypes. BLOB. BFILE. RAW. LONG RAW.
These categories help categorise and organise data in the Oracle database.

Types of classification of SQL statement in Oracle database

DDL includes commands like create, alter, rename, drop and truncate to further divide its structures.

Data Manipulation Language (DML) refers to operations used for manipulating table-level data such as insert, update and delete operations.

Data Control Language (DCL) supports grant and revoke operations while Transaction Control Language (TCL) addresses transactions such as insert, delete and update operations – usually starting off by either commit, rollback or save points operations.

Data Retrieval or Queries Language (DQR) refers to retrieving operations such as SQL statements; in particular, select statements are an example.

Oracle database operations can be divided into five broad categories, known as DDL, DML, DCL, TCL and DQR.

Each category features its own set of operations that together give an in-depth view into database administration.

Create a table in the Oracle database.

Detail of Create Statement. Variables and Data Types Used are listed for easy reference.

An employee table design demonstration is given, including its name and column layout. Data types have also been assigned for employee name, salary, date of birth and any other applicable fields in the table.

Rename Table in Oracle SQL database

The ALTER statement is an indispensable asset in an SQL developer’s toolbox. It enables them to make dynamic changes to an existing table’s structure through four primary operations:

adding/removing/renaming columns/deleting existing ones and changing their data type(s).

Its primary purposes include these operations, like changing column data types or altering table dimensions (increment/decrement, etc.).

To delete columns, use the SQL command “DROP COLUMN”, specifying which column(s) need deleting and execute.

Drop-Table in Oracle SQL database

The DROP SQL command removes tables, views, synonyms and sequences from an Oracle SQL database.

Note that dropping an entire table from this way deletes its entire contents while rendering all views, synonyms or sequences associated with it as invalid.

Use “drop table” followed by the table name to delete or remove student tables from a database.

Insert data into a table.

The INSERT command allows users to add data into a database table by specifying column names and values in an ordered manner.

Delete a row in the Oracle database

Deleting rows from tables using an Oracle database can be done efficiently using its deletion function, which uses “delete from table name followed by condition.” To delete multiple rows in one operation.

As with any modification, it’s crucial that the table in which you wish to make modifications be part of your schema, while your user account has enough permissions and authorizations in order to delete records from being added back into it.

Update rows in the Oracle SQL database

To use the UPDATE statement effectively in Oracle databases, one must understand its syntax, required permissions, and conditions for updating columns or rows.

You should also understand its required permissions and any specific conditions necessary for updating individual columns or rows.

UPDATE statements are straightforward; include an update table’s name after “UPDATE”, change column values accordingly, specify your WHERE clause criteria for updating selected rows, and update those.

Retrieve data from the table

The SELECT statement can retrieve any table, such as employee tables.

For instance, to retrieve records from an equivalent department table such as Department 19 using this SELECT statement: (SELECT department_ID AS department_ID);

Types of Logical Operators

To enhance querying abilities, Oracle offers three logical operators to improve querying: OR (Disjunction), NOT (Negation), and AND (Conjunction). Each can be applied directly in SQL SELECT statements, not specifically used to negate expressions.

Queries can be constructed using either AND or AND-OR operators; some non-logical operators also serve this negation function; properly implementing such operators in Oracle databases ensures efficient data management and manipulation.
