如何使用Go将postgres中的等于(=)更改为不等于(<>

import (
    "database/sql"
    "fmt"
    "log"

    _ "github.com/lib/pq"
)

func main() {
    // 连接数据库
    db, err := sql.Open("postgres", "host=localhost port=5432 user=your_username password=your_password dbname=your_database sslmode=disable")
    if err != nil {
        log.Fatal(err)
    }
    defer db.Close()

    // 测试连接
    err = db.Ping()
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println("Successfully connected to the database!")
}

func executeQuery(db *sql.DB, query string) {
    rows, err := db.Query(query)
    if err != nil {
        log.Fatal(err)
    }
    defer rows.Close()

    for rows.Next() {
        var column1 string
        var column2 int
        // 根据实际的表结构定义变量类型和名称

        err := rows.Scan(&column1, &column2)
        if err != nil {
            log.Fatal(err)
        }

        fmt.Println(column1, column2)
    }

    err = rows.Err()
    if err != nil {
        log.Fatal(err)
    }
}

func main() {
    // 连接数据库...

    query := "SELECT column1, column2 FROM your_table WHERE column1 <> 'value'"
    executeQuery(db, query)
}
