=head2 moveCollateralDown ( tableName, keyName, keyValue [ , setName, setValue ] )
|
|
|
|
Moves a collateral data item down one position. This assumes that the collateral data table has a column called "assetId" that identifies the wobject, and a column called "sequenceNumber" that determines the position of the data item.
|

|
An iid that uniquely identifies this collateral data item.

=head2 setCollateral ( tableName,keyName,properties [,useSequenceNumber,useAssetId,setName,setValue] )
|
|
|
|
Performs and insert/update of collateral data for any wobject's collateral data. Returns the primary key value for that row of data.
|
|
|
|
=head3 tableName
|
|
|
|
The name of the table to insert the data.
|
|
|
|
=head3 keyName
|
|
|
|
The column name of the primary key in the table specified above.
|
|
|
|
=head3 properties
|
|
|
|
A hash reference containing the name/value pairs to be inserted into the database where the name is the column name. Note that the primary key should be specified in this list, and if it's value is "new" or null a new row will be created.
|
|
|
|
=head3 useSequenceNumber
|
|
|
|
If set to "1", a new sequenceNumber will be generated and inserted into the row. Note that this means you must have a sequenceNumber column in the table. Also note that this requires the presence of the assetId column. Defaults to "1".
|
|
|
|
=head3 useAssetId
|
|
|
|
If set to "1", the current assetId will be inserted into the table upon creation of a new row. Note that this means the table better have a assetId column. Defaults to "1".
|
|
|
|
=head3 setName
|
|
|
|
If this collateral data set is not grouped by assetId, but by another column then specify that column here. The useSequenceNumber parameter will then use this column name instead of assetId to generate the sequenceNumber.
|
|
|
|
=head3 setValue
|
|
|
|
If you've specified a setName you may also set a value for that set. Defaults to the value for this id from the wobject properties.
