I get an error when trying to connect to an oracle database. How to fix it?

问题

dbInfo := DbInfo{
Username: "ADMIN",
Password: "Ddbstjrld1!a",
Server: "adb.ap-seoul-1.oraclecloud.com",
Port: "1522",
Service: "gee9edfb92f3cf6_redglqwayxqefhhf_high.adb.oraclecloud.com",
WalletLocation: "/Users/temp1/Desktop/Wallet_REDGLZWEYXQEFHHF",
}

dbString := fmt.Sprintf(`user="%v" password="%v" connectString="tcps://%s:%s/%s?wallet_location=%s"`, dbInfo.Username, dbInfo.Password, dbInfo.Server, dbInfo.Port, dbInfo.Service, dbInfo.WalletLocation)

db, err := sql.Open("godror", dbString)
if err != nil {
	fmt.Println(err.Error())
}
defer db.Close()

r, err := db.Exec(`CREATE TABLE member_table (
	seq        INT NOT NULL AUTO_INCREMENT,
	mb_id     VARCHAR(20),
	mb_pw    VARCHAR(100),
	address   VARCHAR(100),
	mb_tell    VARCHAR(20),  
	 PRIMARY KEY(seq)
   ) ENGINE= MYISAM CHARSET=utf8;`)

if err != nil {
	fmt.Println(err.Error())
}

fmt.Println(r)

我第一次使用Oracle。我查看了手册并按照指示操作,但是无法解决问题。

运行查询时出错
ORA-00000: DPI-1047: 无法找到64位Oracle客户端库:"dlopen(libclntsh.dylib, 0x0001): tried: 'libclntsh.dylib' (no such file), '/usr/local/lib/libclntsh.dylib' (no such file), '/usr/lib/libclntsh.dylib' (no such file), '/Users/temp1/project/oracleDatabase/libclntsh.dylib' (no such file)"。请参考https://oracle.github.io/odpi/doc/installation.html#macos获取帮助

通过DBeaver连接时,一切正常,但是使用上述代码在Golang中连接时,返回以下错误。

我已经苦苦挣扎了几天,如果您能给我展示一个简单的示例,我认为我可以在分析中学习,您能帮助我吗?

英文:

dbInfo := DbInfo{
Username: "ADMIN",
Password: "Ddbstjrld1!a",
Server: "adb.ap-seoul-1.oraclecloud.com",

dbString := fmt.Sprintf(`user="%v" password="%v" connectString="tcps://%s:%s/%s?wallet_location=%s"`, dbInfo.Username, dbInfo.Password, dbInfo.Server, dbInfo.Port, dbInfo.Service, dbInfo.WalletLocation)

db, err := sql.Open("godror", dbString)
if err != nil {
	fmt.Println(err.Error())
}
defer db.Close()

r, err := db.Exec(`CREATE TABLE member_table (
	seq        INT NOT NULL AUTO_INCREMENT,

	mb_tell    VARCHAR(20),  
	 PRIMARY KEY(seq)
   ) ENGINE= MYISAM CHARSET=utf8;`)

if err != nil {
	fmt.Println(err.Error())
}

fmt.Println(r)

I am using oracle for the first time. I checked the manual and followed it, but I can't solve it.

Error running query
ORA-00000: DPI-1047: Cannot locate a 64-bit Oracle Client library: "dlopen(libclntsh.dylib, 0x0001): tried: 'libclntsh.dylib' (no such file), '/usr/local/lib/libclntsh.dylib' (no such file), '/usr/lib/libclntsh.dylib' (no such file), '/Users/temp1/project/oracleDatabase/libclntsh.dylib' (no such file)". See https://oracle.github.io/odpi/doc/installation.html#macos for help

When connecting through dbeaver, it works normally, but when connecting with the above code in golang, the following error is returned.

I've been struggling for several days, if you show me a simple example, I think I can study while analyzing it, can you help me?

得分: 1

更新:正如Christopher Jones所指出的,由于商标问题,goracle已被弃用。替代方案是godror

要使用它,请运行:

go get github.com/godror/godror@latest

然后安装Oracle客户端库。按照其文档建立连接。

根据godror的文档,您必须注意:

> godror是一个cgo包。如果您想使用godror构建应用程序,您需要gcc(C编译器)。


<s>
根据提到的错误,您需要导入Oracle驱动程序goracle以便database/sql可以与Oracle数据库一起使用。

import (
	&quot;database/sql&quot;

	// 导入Oracle驱动程序
	_ &quot;gopkg.in/goracle.v2&quot;
)

附注:我建议在引发该错误的问题陈述中添加行号,以便可以轻松进行调试。

英文:

Update: As pointed out by Christopher Jones, goracle has been deprecated because of trademark issues. The replacement is godror

To use it, run:

go get github.com/godror/godror@latest

and then install Oracle Client libraries. Follow its documentation to make a connection.

As per godror documentation, you must be aware of:

> godror is cgo package. If you want to build your app using godror, you
> need gcc (a C compiler).


<s>
As per the mentioned error, you need to import oracle driver goracle for database/sql to work with an oracle database.

import (
	&quot;database/sql&quot;

	// Import the Oracle driver
	_ &quot;gopkg.in/goracle.v2&quot;
)

P.S.: I would suggest to add line number in question statement which raised that error so that it can be debugged easily.
