我试图使用连接消息在Postgresql函数中引发问题，但在运行时收到错误消息：Postgresql字符串连接：错误：语法错误位于或接近；味精；,postgresql,runtime-error,string-concatenation,stored-functions,Postgresql,Runtime Error,String Concatenation,Stored Functions,我试图使用连接消息在Postgresql函数中引发问题，但在运行时收到错误消息： error: syntax error at or near "msg" 代码如下： CREATE OR REPLACE FUNCTION insertUserAccount( id bigint, nname varchar(40), email varchar(40), pwd varchar,
