COM_STMT_SEND_LONG_DATA

This command sends long data, such as BLOB or TEXT values, in chunks for a specific parameter of a prepared statement.

When data for a specific column is large, it can be sent separately to avoid the limitation of max_allowed_packet (see packet splitting).

Multiple COM_STMT_SEND_LONG_DATA commands with the same column ID append the data. COM_STMT_SEND_LONG_DATA is sent before COM_STMT_EXECUTE.

Fields

• int<1> 0x18 COM_STMT_SEND_LONG_DATA header.

• int<4> statement id.

• int<2> parameter number.

• byte data.

Response
