Rui Wang created BEAM-7623:
------------------------------
Summary: Support select MAP with Row as values
Key: BEAM-7623
URL: https://issues.apache.org/jira/browse/BEAM-7623
Project: Beam
Issue Type: Improvement
Components: dsl-sql
Reporter: Rui Wang
```
Schema primitiveFieldsScema =
Schema.builder().addStringField("color").build();
Schema inputSchema = Schema.builder().addMapField("mapWithValueAsRow",
FieldType.STRING, FieldType.row(primitiveFieldsScema)).build();
Map<String, Row> mapWithValueAsRow = new HashMap<>();
Row row = Row.withSchema(primitiveFieldsScema).addValue("RED").build();
mapWithValueAsRow.put("key", row);
Row rowOfMap =
Row.withSchema(inputSchema).addValue(mapWithValueAsRow).build();
Query used:
select PCOLLECTION.mapWithValueAsRow['key'].color as color
from PCOLLECTION
```
With exception:
```
