RelDataTypeFactory.createArrayType介绍

[英]Creates an array type. Arrays are ordered collections of elements.
[中]创建一个数组类型。数组是元素的有序集合。

代码示例

public static RelDataType convert(ListTypeInfo lstType,
 RelDataTypeFactory dtFactory) throws CalciteSemanticException {
 RelDataType elemType = convert(lstType.getListElementTypeInfo(), dtFactory);
 return dtFactory.createArrayType(elemType, -1);
}

代码示例来源：origin: apache/drill

public static RelDataType convert(ListTypeInfo lstType,
 RelDataTypeFactory dtFactory) throws CalciteSemanticException {
 RelDataType elemType = convert(lstType.getListElementTypeInfo(), dtFactory);
 return dtFactory.createArrayType(elemType, -1);
}

代码示例来源：origin: apache/drill

private RelDataType getRelDataType(ListTypeInfo listTypeInfo) {
 RelDataType listElemTypeInfo = convertToRelDataType(listTypeInfo.getListElementTypeInfo());
 return typeFactory.createArrayType(listElemTypeInfo, -1);
}

代码示例来源：origin: apache/kylin

if (sqlTypeName == SqlTypeName.ARRAY) {
  String innerTypeName = dataType.getName().split("<|>")[1];
  result = typeFactory.createArrayType(createSqlType(typeFactory, DataType.getType(innerTypeName), false),
      -1);
} else if (precision >= 0 && scale >= 0)
