----------------------------------

             Summary: Dimension table do not support computed column
                 Key: FLINK-15366
                 URL: https://issues.apache.org/jira/browse/FLINK-15366
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Planner
    Affects Versions: 1.10.0
            Reporter: Leonard Xu


In Flink 1.10, we bring computed column feature, but I found dimension table do not support this feature.

public static final String mysqlCurrencyDDL = "CREATE TABLE currency (\n" +
 " currency_id BIGINT,\n" +
 " currency_name STRING,\n" +
 " rate DECIMAL(38, 4),\n" +
 " currency_time TIMESTAMP(3),\n" +
 " country STRING,\n" +
 " timestamp6 TIMESTAMP(6),\n" +
 " currency_next as currency_id + 1,\n" +
 " time6 TIME(6),\n" +
 " gdp DECIMAL(10, 4)\n" +
 ") WITH (\n" +
 " 'connector.type' = 'jdbc',\n" +
 " 'connector.url' = 'jdbc:mysql://localhost:3306/test',\n" +
 " 'connector.username' = 'root'," +
 " 'connector.table' = 'currency',\n" +
 " 'connector.driver' = 'com.mysql.jdbc.Driver',\n" +
 " 'connector.lookup.cache.max-rows' = '500', \n" +
 " 'connector.lookup.cache.ttl' = '10s',\n" +
 " 'connector.lookup.max-retries' = '3'" +
 ")";
