我正在尝试将一些内容合并table1到table2另一个table3. 我启动并运行了以下查询PostgreSQL：
CREATE TABLE table3 AS SELECT
table1.orig_zon AS orig_zon,
table1.dest_zon AS dest_zon,
table1.same_zon AS same_zon,
table1.adjacent AS adjacent,
table1.distance AS distance,
table1.da_ivtt AS da_ivtt1,
table1.da_ovtt AS da_ovtt1,
table1.tr_avail AS tr_avail1,
table1.tr_ivtt AS tr_ivtt1,
table1.tr_ovtt AS tr_ovtt1,
table1.tr_cost AS tr_cost1,
table1.au_cost AS au_cost1,
table1.sr_ivtt AS sr_ivtt1,
table1.sr_cost AS sr_cost1,
table2.da_ivtt AS da_ivtt2,
table2.da_ovtt AS da_ovtt2,
table2.tr_avail AS tr_avail2,
table2.tr_ivtt AS tr_ivtt2,
table2.tr_ovtt AS tr_ovtt2,
table2.tr_cost AS tr_cost2,
table2.au_cost AS au_cost2,
table2.sr_ivtt AS sr_ivtt2,
table2.sr_cost AS sr_cost2,
FROM table1, table2
WHERE ((table1.orig_zon = table2.orig_zon)) AND ((table1.dest_zon = table2.dest_zon));
我已经测试了一个非常小的虚拟数据集的查询，结果符合预期。但是我的实际数据库在SQLite其中，当我通过 Linux shell 在 sqlite3 中运行它时，我收到一个错误：
Error: near "table1": syntax error
谁能指出我需要做的修改才能在 SQLite 中进行这项工作？谢谢您的帮助！
Edit1：删除尾随逗号后（请参阅下面的 Craig 的评论），问题仍然存在。
Edit2：玩了一会儿后，我找到了解决方法。看起来很傻，但是如果我要在一行中传递查询的内容，那么该语句就可以工作！
table2.sr_ivtt AS sr_ivtt2,
table2.sr_cost AS sr_cost2 FROM table1, table2 WHERE ((table1.orig_zon = table2.orig_zon)) AND ((table1.dest_zon = table2.dest_zon));
哦！类型转换的祸根！！
