Timo Walther created FLINK-3153:
-----------------------------------

             Summary: Support all comparisons for String type
                 Key: FLINK-3153
                 URL: https://issues.apache.org/jira/browse/FLINK-3153
             Project: Flink
          Issue Type: Improvement
          Components: Table API
            Reporter: Timo Walther


Currently, the Table API does not support comparisons like "STRING < STRING", "STRING >= STRING". The ExpressionCodeGenerator needs to be adapted for that. It might be necessary to define the order in the TableConfig as this maybe depends on the Locale. We should implement it according to SQL implementations.
