X DevAPI User Guide  /  Working with Relational Tables  /  Syntax of the SQL CRUD Functions

6.1 Syntax of the SQL CRUD Functions

The following SQL CRUD functions are available in X DevAPI.

Table.insert()

The Table.insert() method works like an INSERT statement in SQL. It is used to store data in a relational table in the database. It is executed by the execute() function.

The following example shows how to use the Table.insert() function. The example assumes that the test schema exists and is assigned to the variable db, and that an empty table called my_table exists.

MySQL Shell JavaScript Code

// Accessing an existing table
var myTable = db.getTable('my_table');

// Insert a row of data.
myTable.insert(['id', 'name']).
        values(1, 'Imani').
        values(2, 'Adam').
        execute();

MySQL Shell Python Code

# Accessing an existing table
myTable = db.get_table('my_table')

# Insert a row of data.
myTable.insert(['id', 'name']).values(1, 'Imani').values(2, 'Adam').execute()

Node.js JavaScript Code

// Accessing an existing table
var myTable = db.getTable('my_table');

// Insert a row of data.
myTable.insert(['id', 'name']).
        values(1, 'Imani').
        values(2, 'Adam').
        execute();

C# Code

// Assumptions: test schema assigned to db, empty my_table table exists

// Accessing an existing table
var myTable = db.GetTable("my_table");

// Insert a row of data.
myTable.Insert("id", "name")
.Values(1, "Imani")
.Values(2, "Adam")
.Execute();

Python Code

# Accessing an existing table
my_table = db.get_table('my_table')

# Insert a row of data.
my_table.insert(['id', 'name']).values(1, 'Imani').values(2, 'Adam').execute()

Java Code

// Accessing an existing table
Table myTable = db.getTable("my_table");

// Insert a row of data.
myTable.insert("id", "name")
  .values(1, "Imani")
  .values(2, "Adam")
  .execute();

C++ Code

// Accessing an existing table
var myTable = db.getTable("my_table");

// Insert a row of data.
myTable.insert("id", "name")
       .values(1, "Imani")
       .values(2, "Adam")
       .execute();

Table.select()

The Table.select() method works like a SELECT statement in SQL. Notice that Table.select() and collection.find() use different methods for sorting results: Table.select() uses the method orderBy(), reminiscent of the ORDER BY keyword in SQL, while the sort() method is used to sort the results returned by Collection.find().
