One-to-Many : One-to-many or many-to-one relationships occur when one row in one table is linked to many rows in another table. Many-to-Many : In a many-to-many relationship, many rows in one table are linked to many rows in another table.

To create this relationship, add a third table containing the same key column from each of the other tables. Fixed length string. Variable length string. Either Fixed or Variable length string. None of the above. MySQL supports different character sets.

Operations that modify table metadata only. These operations are immediate because the server does not touch table contents. Metadata-only operations include:.

Renaming a column. In NDB Cluster 8. Changing the default value of a column except for NDB tables. Modifying the definition of an ENUM or SET column by adding new enumeration or set members to the end of the list of valid member values, as long as the storage size of the data type does not change.

For example, adding a member to a SET column that has 8 members changes the required storage per value from 1 byte to 2 bytes; this requires a table copy. Adding members in the middle of the list causes renumbering of existing members, which requires a table copy. Changing the definition of a spatial column to remove the SRID attribute. Adding or changing an SRID attribute does require a rebuild and cannot be done in place because the server must verify that all values have the specified SRID value.

The character set change is from utf8mb3 to utf8mb4 , or any character set to binary. For InnoDB tables, statements that modify generated stored columns but do not change their type, expression, or nullability. For non- InnoDB tables, statements that modify generated stored or virtual columns but do not change their type, expression, or nullability. For NDB tables, operations that add and drop indexes on variable-width columns. These operations occur online, without table copying and without blocking concurrent DML actions for most of their duration.

Column modifications of tables containing generated columns that depend on columns with a DEFAULT value if the modified columns are not involved in the generated column expressions. For example, changing the NULL property of a separate column can be done in place without a table rebuild. Adding a column. Limitations apply. NDB Cluster 8. NDB 8. Specifying a non-default value for this clause enables you to require a certain amount of concurrent access or exclusivity during the alter operation, and halts the operation if the requested degree of locking is not available.

The other LOCK clause parameters are not applicable. If not, permit concurrent reads if supported. If not, enforce exclusive access. If supported, permit concurrent reads and writes. Otherwise, an error occurs. If supported, permit concurrent reads but block writes. If concurrent reads are not supported, an error occurs. Enforce exclusive access. The default is to add the column last.
