Suppose I have to select DISTINCT concat(col_1,col_2) as new_col,col_3,col_4,col_5 only as a new table from a table having more than 100 columns.
My method: In the prepare recipe make a new column using the Concat function, then in another step move those 4 columns to keep them in order as mentioned above.
But, then I have to delete all remaining columns manually to get the desired output in a new table, which is a tedious process.
then I will pass my table through the distinct recipe to get my final desired result.
can anyone help me with a better approach than this, especially with that delete step?
Note: I'm not allowed to use any code recipe.
sadly there's no magic here. The "Delete/Keep" column step can let you choose multiple columns by giving an explicit list, of by giving a regular expression to filter column names, and that's about it...
