面向对象风格

maxdb_stmt::stmt_send_long_data ( int `$param_nr` , string `$data` ) : bool

Allows to send parameter data to the server in pieces (or chunks). This function can be called multiple times to send the parts of a character or binary data value for a column, which must be one of the TEXT or BLOB datatypes.

`param_nr` indicates which parameter to associate the data with. Parameters are numbered beginning with 0. `data` is a string containing data to be sent.

> Note:

> For efficiency reasons, this function should be used after calling maxdb_execute(). In this case, the data is not stored on the client side. The end of the sequence must end with a call to maxdb_stmt_close_long_data().

### 返回值

成功时返回 `TRUE`， 或者在失败时返回 `FALSE`。
