Struct to hold information about the table that should be created.
void HA_CREATE_INFO::init_create_options_from_share | ( | const TABLE_SHARE * | share, |
uint64_t | used_fields | ||
) |
Fill HA_CREATE_INFO to be used by ALTER as well as upgrade code.
This function separates code from mysql_prepare_alter_table() to be used by upgrade code as well to reduce code duplication. For ALTER code path, this lets new create options override the old ones.

Algorithm (and possible options) to be used for InnoDB's transparent page compression.
If this attribute is set then it is hint to the storage engine to try and compress the data using the specified algorithm where possible. Note: this value is interpreted by the storage engine only. and ignored by the Server layer.

enum row_type HA_CREATE_INFO::row_type = ROW_TYPE_DEFAULT |
Row type of the table definition.
Defaults to ROW_TYPE_DEFAULT for all non-ALTER statements. For ALTER TABLE defaults to ROW_TYPE_NOT_USED (means "keep the current").
Can be changed either explicitly by the parser. If nothing specified inherits the value of the original table (if present).

Secondary engine of the table.

bool HA_CREATE_INFO::secondary_load {false} |
Secondary engine load status.
