我已经阅读了文档，但仍然不清楚如何使用此函数将此命令发送到服务器：

INSERT INTO table_1($1,$2,$3);

我写的这个函数：

void add_data_to_db(char table){
        const char data[2][2] = {"12","me"};
        re = PQexecParams(connection,
                        "INSERT INTO test_table($1,$2)",
                        2,data,NULL,NULL,NULL,0
                        );
}

但在编译过程中，会出现以下错误：

db.c: In function ‘add_data_to_db’:
db.c:40:6: warning: passing argument 4 of ‘PQexecParams’ from incompatible pointer type [-Wincompatible-pointer-types]
   40 |    2,data,NULL,NULL,NULL,0
