    • Method Detail

      • generateTypeString

        protected void generateTypeString​(java.lang.StringBuilder sb,
                                          boolean withDetail)
        Description copied from class: RelDataTypeImpl
        Generates a string representation of this type.
        Specified by:
        generateTypeString in class RelDataTypeImpl
        Parameters:
        sb - StringBuilder into which to generate the string
        withDetail - when true, all detail information needed to compute a unique digest (and return from getFullTypeString) should be included;
      • getPrecision

        public int getPrecision()
        Description copied from interface: RelDataType
        Gets the JDBC-defined precision for values of this type. Note that this is not always the same as the user-specified precision. For example, the type INTEGER has no user-specified precision, but this method returns 10 for an INTEGER type.

        Returns RelDataType.PRECISION_NOT_SPECIFIED (-1) if precision is not applicable for this type.

        Specified by:
        getPrecision in interface RelDataType
        Overrides:
        getPrecision in class RelDataTypeImpl
        Returns:
        number of decimal digits for exact numeric types; number of decimal digits in mantissa for approximate numeric types; number of decimal digits for fractional seconds of datetime types; length in characters for character types; length in bytes for binary types; length in bits for bit types; 1 for BOOLEAN; -1 if precision is not valid for this type
