To retrieve all the records present in a database that do not satisfy the specified pattern using MySQL Query through Node.js program, we need to execute the “SELECT” statement using the query() function of the mysql2 library as follows −

sql = "SELECT * FROM person_tbl WHERE NAME NOT REGEXP ''^sa''";
con.query(sql);

To retrieve all the records present in a database that do not satisfy the specified pattern using MySQL Query through Java program, we need to execute the “SELECT” statement using the JDBC function executeUpdate() as −

String sql = "SELECT * FROM person_tbl WHERE NAME NOT REGEXP ''^sa''";
statement.executeQuery(sql);

To retrieve all the records present in a database that do not satisfy the specified pattern using MySQL Query through Python program, we need to execute the “SELECT” statement using the execute() function of the MySQL Connector/Python as −

sql = "SELECT * FROM person_tbl WHERE NAME NOT REGEXP ''^sa''" 
cursorObj.execute(sql)

var mysql = require(''mysql2'');
var con = mysql.createConnection({
host:"localhost",
user:"root",
password:"password"
});
 //Connecting to MySQL
 con.connect(function(err) {
 if (err) throw err;
  //console.log("Connected successfully...!");
  //console.log("--------------------------");
 sql = "USE TUTORIALS";
 con.query(sql);
 sql = "SELECT * FROM person_tbl WHERE NAME NOT REGEXP ''^sa''";
 console.log("Select query executed successfully..!");
 console.log("Table records: ");
 con.query(sql);
 con.query(sql, function(err, result){
 if (err) throw err;
 console.log(result);
 });
});    

Output

The output produced is as follows −
