Question
How can you list all the columns of a table using Apache sqoop?
Answers
There is no straight way to list all the columns of a table in Apache Sqoop like sqoop-list-columns, so first we should retrieve the columns of the particular table and transform to a file containing the column names of particular table.Syntax is:

Sqoop import –m1 –connect ‘jdbc:sqlserver://servername;database=databasename;
Username-DeZyre;password=mypassword’ –query “SELECT column_name,DATA_TYPE FROM INFORMATION_SCHEMA columns WHEREtable_name=’mytableofinterest’ AND $CONDITIONS” –target-dir ‘mytableofinterest_column_name’.   Your Comment
