HI All i have a sql table named schema, which has two column input_schema and output_schema. input_schema | output_schema a | x b | y c | z apart from this table i have another table named input_table which has three columns named a,b,c and has some data in it. Now i have to copy data of input_table into a csv file, which will have columns x,y,z. Mapping of a,b,c to x,y,z must be according to the schema_table given above. Thanks
