DML - Data Manipulation Language

The purely read-only SELECT query statement is classed with the 'SQL-data' statements 

The SELECT ... INTO form is considered to be DML because it manipulates (i.e. modifies) data.

SELECT Column1, Column2
INTO DestinationTable

FROM SourceTable

Copy Coumn1,Column2 From SourceTable to DestinationTable.


So Select is dml statement

Insert, Update and Delete
