This query will help you adjust due dates en masse, especially if a Reset Due Date operation has gone wrong. The query pulls in needed information and drops it into a temporary table that can be used to calculate the proper due date based off the most recent checkout date in Polaris.

-- Create a table to hold onto data and calculated dates
CREATE TABLE #TempItemData (
    ItemRecordID INT,
    PatronID INT,
    LoanPeriodCodeID INT,
    PatronCodeID INT,

    CheckoutDate DATETIME,
    DueDate DATETIME,
    TimeUnit INT,
    Units INT,
    NewDueDate DATETIME
);


-- Populate the temp table
INSERT INTO #TempItemData

    ico.DueDate, -- The current, and likely wrong due date
    lp.TimeUnit, -- The time units used based upon LoanPeriod data (Days, Hours, Minutes)
    lp.Units, -- The actual number of the above units
