What is the difference between Oracle SQL and other SQL

Oracle SQL is a specific type of SQL. It is a structured query language used for data query, update, insertion and other operations in Oracle relational database. SQL (Structured Query Language) is a general query language that is supported by almost all relational database management systems, but different database management systems may have some differences.

So, what is the difference between Oracle SQL and other SQL?

1. Syntax differences: Although generally speaking, Oracle SQL has the same general syntax as other SQL, there are still some syntax differences. For example, creating a table in Oracle SQL requires "create table", while MySQL uses "create table if not exists".
2. Data type: The data types supported by Oracle SQL are different from other SQL. For example, the date and time data type in Oracle SQL is DATE, while MySQL uses DATETIME.
3. Stored procedures and functions: Oracle SQL can create stored procedures and functions and write them through PL/SQL. Other SQL may use different ways to create stored procedures and functions.

When using different SQL, you also need to consider their respective characteristics. For example, in large enterprise-level applications, Oracle SQL has better performance and scalability, and can provide more reliable responses during high concurrent access. In this regard, its advantages are unmatched by other SQL.

In short, although all SQLs are basically the same in structure, there are still some differences in details. Only by deeply understanding the characteristics and usage of each SQL can we maximize their role and achieve optimal results in projects.
