memo

The memo table stores the case memo data before upgrading to iProcess Engine 11.6. Since iProcess Engine 11.6, all the new case memo data is stored in the BLOB data type in the nmemo table.

You can migrate case memo data in the memo table to the nmemo table when upgrading to iProcess Engine 11.6 or migrate them by using the swutil MIGRATEMEMOS command after the upgrades.

Note: A copy of a memo is saved in the pack_memo table if the memo is marked on an outstanding form.

Structure

The memo table has the following structure:

TABLE memo (
node_id		number(5) 		        NOT NULL,
proc_id		number(5)  		        NOT NULL,
casenum		number(20)		NOT NULL,
memo_id		number(4)			NOT NULL,
memo_index	number(10)			NOT NULL,
memo_size	number(10)			NOT NULL,
memo_data	blob     NOT NULL,
array_idx	number(6)			NOT NULL)

Column

Description

node_id

ID of the node that this memo is hosted on, as defined in the nodes table.

proc_id

ID of the procedure that this memo belongs to, as defined in the proc_index table.

casenum

Case number that this memo belongs to, as defined in the case_information table.

memo_id

Unique (for this case) ID of this memo.

memo_index

Index number into the set of rows that make up this memo.

If a memo is longer than 30,000 bytes multiple rows (in 30,000 byte chunks) are used to store the memo data. Each segment of the memo data is uniquely identified by its memo_index value.

Note: If you have upgraded your system from iProcess Engineone of the following versions, existing memos are divided into 2,000 byte chunks:
— (UNIX Oracle) any Version i9.n-o iProcess Engine, or from a pre-Version 9.0-o(0.15) Process Engine.
— (Windows Oracle) any Version 9.0-o Process Engine.

However, if a memo is modified, the existing rows are deleted and then re-added using 30,000 byte chunks.

memo_size

Size (in bytes) of the memo data for this row.

memo_data

Memo data.

array_idx

Either:

• The array element index number of the memo.
• -1, if the memo is not an array memo field.
