SQL Commands and Syntax
- SQL isn’t case sensitive. However, such capitalizing commands as SELCT and CREATE is great coding practice.
- SQL ignores white space. However, formatting code into several lines is a very practical coding convention as well, because it makes code more readable.
- You can define character or text-based value in SQL by including values inside quotes (‘ ‘). On the other hand, boolean and numeric values shouldn’t be enclosed in quotation marks.
- Every SQL statement is punctuated with a semicolon. It makes it possible for lots of database systems to process several SQL statement in one call.
- SQL has a core syntax, however various database platforms such as MySQL, Oracle, and MS SQL implement various SQL extensions that porting one form another needs a bit of code tweaking. If you have troubles with it, use our SQL help.
- SQL syntax depends on specific commands that you are using like CREATE or ORDER BY.
It it high time to use other common SQL commands. The INSERT INTO command includes a new record into the table by
- specifying the table name
- specifying the columns where the new values should be inserted
- using the VALUES command that is followed by the respective values in single quotes and inside parentheses
