[jira] [Created] (FLINK-3153) Support all comparisons for String
type
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.
