I am new to Vertica and I am working on Data Cleaning. I have a source table(raw table) which may have duplicate records. I need to filter the records based on the columns given by user(maximun upto 3 columns) and insert into a target table.
I have written a query like this - INSERT INTO OUTPUTTABLE SELECT * FROM INPUTTABLE WHERE 1 GROUP BY column1,column2,column3;
This query is throwing an error that "Column "test_tb.col3" must appear in the GROUP BY clause or be used in an aggregate function"
ie Group by clause is expecting all the columns as in select *.
Can any one help me in correcting this query?
