Workflow database field size limitationsThe workflow database software sets limits on the amount of data you can store in a workflow field. These limits are both specific to a field and cumulative for a record. The following table describes the limitations set by specific versions of Microsoft SQL Server and Oracle.
* Bytes do not necessarily equal characters. If you use a multi-byte character set, the maximum number of characters you can insert into a column is less than the maximum bytes supported. The maximum number of characters is then determined by the bytes per character. This includes the required Process Engine system fields for each roster, queue, and event log. For BLOB columns, the data is not stored in the row itselfrather it is stored in another area of the database. Only the address to the data is stored in the row. The address does not significantly impact the maximum amount of actual data which can be stored in a row. Therefore, unexposed data fields can be larger in size (and total row size) than the limits appear to suggest.
