Solve the following python programming problem given the following code:
def _emit_delete_statements(base_mapper, uowtransaction, cached_connections, mapper, table, delete) : 
    'Emit DELETE statements corresponding to value lists collected
    by _collect_delete_commands().' 
    need_version_id = ((mapper.version_id_col is not None) and table.c.contains_column (mapper.version_id_col)) 
    def delete_stmt() : 
        clause = sql.and_ () 
        for col in mapper._pks_by_table [table] : 
            clause.clauses.append ((col == sql.bindparam (col.key, type_ = col.type))) 
if need_version_id : 
            clause.clauses.append ((mapper.version_id_col == sql.bindparam (mapper.version_id_col.key, type_ = mapper.version_id_col.type))) 
return table.delete (clause) 
for (connection, del_objects) in delete.items () : 
        statement = base_mapper._memo (('delete', table), delete_stmt) 
        connection = cached_connections [connection] 
        expected = len (del_objects) 
        rows_matched = (- 1) 
        only_warn = False 
        if connection.dialect.supports_sane_multi_rowcount : 
            c = connection.execute (statement, del_objects) 
            if (not need_version_id) : 
                only_warn = True 
rows_matched = c.rowcount 
else : 
            if need_version_id : 
                if connection.dialect.supports_sane_rowcount : 
                    rows_matched = 0 
                    for params in del_objects : 
                        c = connection.execute (base_mapper, params) 
                        rows_matched += c.rowcount

else : 
                connection.execute (statement, del_objects) 
if (base_mapper.confirm_deleted_rows and (rows_matched > (- 1)) and (expected != rows_matched)) : 
            if only_warn : 
                util.warn (("DELETE statement on table '%s' expected to delete %d...

    
    

    Fix the buggy line: c = connection.execute (base_mapper, params)
assistant
#Here is Python code to fix the buggy line: c = connection.

c = connection.execute (statement, params)
