根据查询插入insert into select from

数量比较大时,可以直接根据SELECT插入,跳过网络IO会快许多
//INSERT INTO A SELECT * FROM B
//与查询方法参数一致,在查询方法基础上 加一个插入目标表
ServiceProxy.insert("crm_user(ID,CODE)", "sso_user(ID,CODE)", "id > 0");
//INSERT INTO CRM_USER(ID, CODE) SELECT ID, CODE FROM SSO_USER WHERE ID > 0

ConfigStore configs = new DefaultConfigStore();
configs.and("ID", 1);
Table tab = new Table<>("crm_user");
tab.addColumn(new Column("ID"));
tab.addColumn(new Column("CODE"));
ServiceProxy.insert(tab, new Table("crm_user"), configs.columns("BID","BCODE"));
//INSERT INTO CRM_USER(ID, CODE) SELECT BID, BCODE FROM SSO_USER WHERE ID = 1

//复杂的查询可以先构造RunPrepare
RunPrepare prepare = TableBuilder.init("crm_user(a.id, b.code) as a").left("hr_user as b","a.id = b.id").build();
ServiceProxy.insert("crm_user(id,code)", prepare,0,9, "a.id>1");
/*INSERT INTO crm_user(id, code)
SELECT
	a.id,b.code
FROM
	crm_user a
	LEFT JOIN hr_user b ON a.id = b.id
WHERE a.id>1 LIMIT 10 OFFSET 0
