Question

Accepted Answer

Using cursors in X++: Cursors are used to iterate over result sets. Example:


// Declare a cursor
SqlStatementExecutePermission perm;
str sql = 'SELECT AccountNum, Name FROM CustTable';
ResultSet resultSet;
SqlDatabase sqlDB = new SqlDatabase();
Cursor cursor = sqlDB.createStatement().executeQuery(sql);
perm = new SqlStatementExecutePermission(sql);
perm.assert();

// Open and iterate cursor
while (cursor.next())
{
    info(cursor.getString(1)); // AccountNum
    info(cursor.getString(2)); // Name
}

// Close cursor
cursor.close();
