Helper function to get the string representation of a RelDataType (include precision/scale but no charset or collation).

参数:

sqlType - Type

返回:

String representation of type

getTypes

public static List<org.apache.calcite.rel.type.RelDataType> getTypes(org.apache.calcite.rel.type.RelDataTypeFactory typeFactory)

Returns a list of typical types.

                                      String[] inputValues)

generateAggQueryWithMultipleArgs

public static String generateAggQueryWithMultipleArgs(String expr,
                                                      String[][] inputValues)

generateWinAggQuery

public static String generateWinAggQuery(String expr,
                                         String windowSpec,
