They must be of INTEGER or BIGINT type and are automatically primary key columns (as a result, multi-column primary keys are not possible with an IDENTITY column present). GRANT SELECT TO PUBLIC ON AB GRANT SELECT TO JOE ON CD; Note that this example consists of one CREATE SCHEMA statement which is terminated by a semicolon

How to add column in specific position

So, I can understand why people would like to have their columns ordered and not add new columns at the end - although I probably wouldn't trouble myself, if the table is already in production

ALTER TABLE statement

If the column is contained in any multicolumn index, uniqueness constraint, foreign key, or primary key, then the index, constraint, or key must be deleted before the column can be deleted. MOVE TABLE METADATA The MOVE TABLE METADATA clause moves the metadata of the table, such as the EBM, DeleteBM, and InsertBM of the table, to a new dbspace

Subpartitions and LOB subpartitions of that partition that you create subsequently will inherit these values unless you override them explicitly when creating the subpartition or LOB subpartition. You cannot specify this clause if the column was created or added using the IS OF TYPE syntax, which limits the range of subtypes permitted in an object column or attribute to a particular subtype

HASH should not be used as a composite type in cases where range queries or similarity queries on the composite keys are a signficant part of the workload, VALUE should be used instead. decimal types when the constraint is a composite key when the constraint is a non-unique constraint BTREE All other cases than specified for CPBTREE UNIQUE Specifies a column as a unique key

These keywords are deprecated beginning with MySQL Cluster NDB 7.3; they continue to be supported in MySQL Cluster NDB 7.4, but are subject to removal in a future version of MySQL Cluster. Updates and writes to the table that begin after the ALTER TABLE operation begins are stalled until the new table is ready, then are automatically redirected to the new table without any failed updates

The reason, I like to call it interesting is though, I have provided answers to him, I believe there should be another better alternative to this problem. However, what will be the alternative solution to this question if the clustered index is already created on the table and there was no option to modify the same

Updates and writes to the table that begin after the ALTER TABLE operation begins are stalled until the new table is ready, then are automatically redirected to the new table without any failed updates. 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 will require a table copy

ALTER TABLE only allows columns to be added that can contain nulls, or have a DEFAULT definition specified, or the column being added is an identity or timestamp column, or alternatively if none of the previous conditions are satisfied the table must be empty to allow addition of this column.

PostgreSQL: Documentation: 9.2: ALTER TABLE


  http://www.postgresql.org/docs/9.2/static/sql-altertable.html
VALIDATE CONSTRAINT This form validates a foreign key or check constraint that was previously created as NOT VALID, by scanning the table to ensure there are no rows for which the constraint is not satisfied. (This requires superuser privilege if any of the triggers are internally generated constraint triggers such as those that are used to implement foreign key constraints or deferrable uniqueness and exclusion constraints.) USER Disable or enable all triggers belonging to the table except for internally generated constraint triggers such as those that are used to implement foreign key constraints or deferrable uniqueness and exclusion constraints

alter table abc ADD dad varchar(50) after parentname But it throws me the following error message Msg 170, Level 15, State 1, Line 1 Line 1: Incorrect syntax near 'after'. If you look at a page of data (for example, by using DBCC PAGE in MSSQL) you will see that the storage order of the fields does not correspond to the order you specified in the CREATE TABLE statement
