我的代码是
connect 'jdbc:derby:sampleclient';
set schema SYMMETRIC;
insert into "sale_transaction" ("tran_id", "store", "workstation", "day", "seq") values (1000, '1', '3', '2007-11-01', 100);
insert into "sale_return_line_item"("tran_id", "item_id"," price", "quantity") values (1000, 110000055, 0.65, 1);
select * from "sale_transaction";
select * from "sale_return_line_item";
我试图从德比中将数据插入到mysql中，即im复制数据，但是当我输入下面的命令时我得到的错误如下所示，而push-derby2mysql是包含代码的文件
C:\symmetric-ds-3.0.1-server\symmetric-ds-3.0.1\samples>sh ij.sh push-derby2my
