我知道了。bindparams的实际值保存在一个称为的对象中，该对象
SQLCompiler通常是特定于方言的。
这里（链接到GitHub）是在
SQLCompiler查询编译过程中将bindparams存储在实例中的位置
因此，我的代码段的最终版本如下所示：
class values(FromClause): named_with_column = True def __init__(self, columns, *args, **kw): self._column_args = columns self.list = args self.alias_name = self.name = kw.pop('alias_name', None) def _populate_column_collection(self): # self._columns.update((col.name, col) for col in self._column_args) for c in self._column_args: c._make_proxy(self, c.name)@compiles(values)def compile_values(clause, compiler, asfrom=False, **kw): def decide(value, column): add_type_hint = False if isinstance(value, array) and not value.clauses: # for empty array literals add_type_hint = True if isinstance(value, ClauseElement): intermediate = compiler.process(value) if add_type_hint: intermediate += '::' + str(column.type) return intermediate elif value is None: return compiler.render_literal_value( value, NULLTYPE ) + '::' + str(column.type) else: return compiler.process( bindparam( None, value=compiler.render_literal_value( value, column.type ).strip("'") ) ) + '::' + str(column.type) columns = clause.columns v = "VALUES %s" % ", ".join( "(%s)" % ", ".join( decide(elem, column) for elem, column in zip(tup, columns)) for tup in clause.list ) if asfrom: if clause.alias_name: v = "(%s) AS %s (%s)" % (v, clause.alias_name, (", ".join(c.name for c in clause.columns))) else: v = "(%s)" % v return v
