DB Connection Go code

Connecting ChistaDATA database from Go code

To connect to ClickHouse via GO, you can use the official ClickHouse GO driver. Here are the steps to connect to ClickHouse via GO:

1. Install the ClickHouse GO driver using the following command:

go get github.com/ClickHouse/clickhouse-go

2. In your GO code, import the necessary packages:

import (
    "database/sql"
    _ "github.com/ClickHouse/clickhouse-go"
)

3. In your code, create a connection to ClickHouse using the following code:

// Replace the placeholders with your ClickHouse server information
dsn := "tcp://<host>:<port>?username=<username>&password=<password>&database=<database>"

// Create the connection
db, err := sql.Open("clickhouse", dsn)
if err != nil {
    // Handle error
}

4. You can now use the db object to execute queries against the ClickHouse database. For example:

// Execute a simple query
query := "SELECT * FROM mytable"
rows, err := db.Query(query)
if err != nil {
    // Handle error
}

// Process the results
for rows.Next() {
    // Do something with the result
}

// Close the resources
rows.Close()

Note that you should always close the resources (rows and db) after using them to free up system resources. Also, make sure to handle errors appropriately in your code.
