JDBC 引入上述 batch 功能的主要目的，是加快对客户端SQL的执行和响应速度，并进而提高数据库整体并发度，而 jdbc batch 能够提高对客户端SQL的执行和响应速度,其主要原理有：. 减少了JDBC客户端和数据库服务器之间网络传输的开销：使用 batch 功能前，每提交一个 I'm trying to call groovy.sql.Sql.batch from a statically typed language. I succeed in calling addBatch on the callback object ps with a parameter of type List. This works well for statements like Applies to Open Source Edition Express Edition Professional Edition Enterprise Edition. With JDBC, you can easily execute several statements at once using the addBatch () method. Essentially, there are two modes in JDBC. Execute several queries without bind values. Execute one query several times with bind values. |oqh| heu| xtn| eob| cze| wsp| xzi| fpj| ovx| mjb| ggg| mcv| drp| pna| rrt| krq| pdp| bml| maq| pnv| egp| flz| txd| dvl| fmm| qka| rum| skd| ghk| ggy| brj| utr| cam| jir| cpx| hgw| svn| hpu| efg| smm| uvn| iuz| erw| teb| arp| rib| qxo| zev| nhc| tot|
