Method: Informix::InsertCursor#put

Defined in:
ext/informixc.c

#put(*args) ⇒ Object

cursor.put(*params)

Binds params as input parameters and executes the insert statement. The records are not written immediatly to disk, unless the insert buffer is full, the flush method is called, the cursor is closed or the transaction is commited.

Examples:

A bulk insert using an insert cursor. Requires a transaction:

db.transaction do |db|
  db.cursor('insert into stock values(?, ?, ?, ?, ?, ?)') |cur|
    cur.open
    # Loading a file separated by '|'
    File.open(filename).each do |line|
      fields = line.split('|')
      cur.put(*fields)
    end
  end
end
