SQL syntax
- The syntax of the structured query language is a unique set of rules and guidelines, which are not case-sensitive.
- Its Syntax is defined and maintained by ISO and ANSI standards.
Some important points about SQL syntax are:
- You can write the Keywords of SQL in both uppercase and lowercase, but writing the SQL keyword in uppercase improves the readability of the SQL query.
- SQL syntax or statements are dependent on text lines We can place a single SQL statement on one or multiple text lines.
- You can perform most of the action in a database with SQL statements.
SQL statements:
- Most of the actions you need to perform on a database are done with SQL statements.
- SQL statements tell the database what operation you want to perform on the structured data and what information you would like to access from the database.
Example:
SELECT “column_name” FROM “table_name”;
- Each SQL statement begins with any of the SQL keywords and ends with the semicolon(;).
- The semicolon is used for separating the multiple SQL statements which are going to execute in the same call.
