通过连接来自不同列的逗号分隔值来生成字符串

SELECT CONCAT(column1, ',', column2, ',', column3) AS concatenated_string
FROM table_name;

column1 = "value1"
column2 = "value2"
column3 = "value3"
concatenated_string = ",".join([column1, column2, column3])
print(concatenated_string)

String column1 = "value1";
String column2 = "value2";
String column3 = "value3";
String concatenatedString = column1 + "," + column2 + "," + column3;
System.out.println(concatenatedString);

var column1 = "value1";
var column2 = "value2";
var column3 = "value3";
var concatenatedString = column1 + "," + column2 + "," + column3;
console.log(concatenatedString);
