Data manipulation languages tend to have many different flavors and capabilities between database vendors. There have been a number of standards established for SQL by
280:(DQL), but it is closely related and sometimes also considered a component of a DML; some operators may perform both selecting (reading) and writing. 276:, with the DML comprising some of the operators in the language. Read-only selecting of data is sometimes distinguished as being part of a separate 331:(DDL). In SQL these two categories are similar in their detailed syntax, data types, expressions etc., but distinct in their overall function. 1034: 199: 137: 90: 45: 109: 364:
