A major upgrade (1.1 -> 1.2 for example) may have issues due to stale
FRM table IDs. This commit adds a stored procedure that changes the
table comment to empty on every ColumnStore table to repair the IDs.
The user should run this as part of the upgrade procedure between major
versions.
CHANGE COLUMN was blocked for TEXT and BLOB types. This fix applies to
things like TINYTEXT as well as the only difference internally is the
column width.
* TEXT and BLOB now have separate identifiers internally
* TEXT columns are identified as such in system catalog
* cpimport only requires hex input for BLOB, not TEXT
This patch allows the following syntax to change the current
autoincrement value for the table:
ALTER TABLE table_name COMMENT='autoincrement=value';
Where "value" is the new integer to be used.
