mysql跨数据库复制表(在同一IP地址中)示例

insert into table1 select       from table2 (完全复制)
insert into table1 select   distinct      from table2(不复制重复纪录）
insert into table1 select   5    from   table2 (前五条纪录)

2、不在同一数据库中（如，db1 table1,db2 table2)

sql:       
[code]
insert into db1.table1 select       from db2.table2 (完全复制)
insert into db1.table1 select   distinct      from db2table2(不复制重复纪录）
insert into tdb1.able1 select   5    from   db2table2 (前五条纪录)

select into desTable from sourceTable在mssql中支持，在mysql中不支持
insert into desTable select from sourceTable
