Make string comparison not case sensitive

    XMLWordPrintable

Details

    Description

      ColumnStore is case sensitive for string comparisons in queries.
      I know that the following query

      select * from table1 where field1='aaa';

      can be made not case sensitive writing

      select * from table1 where field1 collate utf8_general_ci='aaa';

      but, is there a way to make the engine not cs by default, without changing the client code?
      There should be an option for this.
