What Can SQL do?

  • Execution of  queries against a database.
  • Retrieval of  data  from a database.
  • Insertion of records in a database.
  • Updating of records in a database.
  • Deletion of  records from a database.

  • Setting of necessary permissions on tables, procedures, and views as and when needed.

Like most programming languages, there are  different versions of the SQL language, although its specifically an ANSI standard. The different versions have supported the major commands in almost same manner as to be compliant to ANIS standard. In addition to the SQL standard, many of SQL database programs also have their own specific and proprietary extensions.
