所以,windows PostgreSQL 服务器端(server)的默认编码方式为UTF8,在使用中文的windows系统上,操作系统的语言是GBK,所以,windows PostgreSQL 客户端(client)的默认编码方式是GBK。PostgreSQL 支持服务器和客户机之间的自动字符集转换:在此环境下插入汉字,一切正常。此时传到客户端的汉字为GBK编码,自动转为UTF8编码存到...

我们可以通过以下SQL语句来设置数据库连接编码为UTF-8: ALTERDATABASEyour_database_nameSETclient_encodingTO'UTF8'; 1. 步骤2:设置Java项目的编码为UTF-8 在Java项目中,我们也需要确保编码设置为UTF-8。在IDE中,一般可以在项目设置中找到相关选项进行设置。 步骤3:在Java代码中指定连接字符集为UTF-8 在Java代...
我们在使用数据库服务时,通常需要使用客户端连接数据库服务端,以 PostgreSQL 为例,常用的客户端有自带的 psql,JAVA 应用的数据库驱动 JDBC,可视化工具PgAdmin等,这些客户端都需要遵守 PostgreSQL 的通信协议才能与之 "交流"。所谓协议,可以理解为一套信息交互规则或者规范,最为我们熟知的莫过于TCP/IP 协议和HTTP 协...
PGCLIENTENCODING 这是什么鬼,排查一圈连接问题,复制pg下的5个文件到desktop\bin 下,检查postgresql的 dbeaver连接,检查服务启动,检查端口 postgres\ 9.2\data\pg_hba.conf ,都正常使用,最后发现环境变量有个这东西: 删除掉正
