dropColumns

Drop columns from a table

Remove columns from a table.

For example, if you have columns a,b,c,d,e,f,g,h,i,j,k) and want to remove columns j,k, you can easily use the following LQL query where j and k are excluded from the query.

select a, b, c, d, e, f, g, h, i from table

However, the process becomes more tedious and prone to error if the columns have long names, such as a = s3bucketAccountID, b = messageResponseTime, and so on. This operator addresses this issue.
