The Table OR_LOG_TIMING_events had one row for each timing event
documented in a log. You are writing a query that must have one row
for each log, with each timing event in a separate column.
The column TIMING_EVENT_C identifies which timing event is being
documented, & the column Timing_event_DTTM is the time at which
the timing event occurred. The column LOG_ID identifies the log on
which the timing
event was being documented.
Timing_Event_c = 1-- represents the event for IN Facility. Which of the following will return the time a patients was in Facility in a separate column?
A. CASE WHEN TIMING_EVENT_C = 100 THEN MAX(TIMING_EVENT_DTTM)ELSE NULL END
B. MAX(CASE WHEN TIMING_EVENT_C=100 THEN TIMING_EVENT_DTTM ELSE NULL END)
C. CASE WHEN TIMING_EVENT_C = 100 THEN NULL ELSE MAX(TIMING_EVENT_DTTM) END
D. MAX(CASE WHEN TIMING_EVENT_C=100 THEN NULL ELSE TIMING_EVENT_DTTM END)
The correct query is:
A. CASE WHEN TIMING_EVENT_C = 100 THEN MAX(TIMING_EVENT_DTTM) ELSE NULL END
Explanation:
This query will return a single row containing the time log
The Table OR_LOG_TIMING_events had one row for each timing event documented in a log. You are...
The following SQL query returns one row per surgeon. The granularity before GROUP BY is a surgeon-panel combination, in other words, for each surgeon, one panel they performed in. Surgeons can only be listed once per panel, but a log can have more than one panel. SELECT staff.STAFF_NM_WID "surgeon", COUNT( orl.LOG_ID ) "Number of Logs" FROM OR_LOG orl INNER JOIN V_LOG_STAFF staff ON orl.LOG_ID = staff.LOG_ID INNER JOIN OR_LOG_ALL_PROCS procs ON orl.LOG_ID = procs.LOG_ID AND procs.LINE = 1 --First Listed...

For the below questions, use the following schema definition. customer(custid,lname,fname,street,city,state,zip,dob) device(devid,custid,type) device_onoff(ts,devid,pwr) device_chnl(ts,devid,chnl) schedule(start_ts,end_ts,chnl,showid) This is a schema for a tv network. Customers own devices (of a certain type; phone is a device, cable-box is a device, etc.), and they can watch channels on those devices. Whenever a device comes online, we get a device onoff event, indicating device power state. Whenever a device channel changes, we get a device chnl event. There is also a schedule object, which tells...
Complete the table for an aqueous solution @ 25°C each row represents one solution Грн POH 3.25 0.25 (H) (OH) Acidic or basic 6.14x10 12.25 1.77 9.83x102 A 0.185M solution of weak acid has a pH of 2.95. Calculate the lonization constant (K) for the acid. For this you will need to determine the relationship between the [HA], and the [H01. You're given [HA] and you'll need to find [H,0+- you can get this from pH. Just as we have...
D Chapter 15 Problem Set Suppose you are planning a study that will est the following one-tailed hypotheses: To evaluate the power of your study, you consider a specific alternative hypothesis, μ-Ha, where μ.> μ。. The following sketch shows two overlapping sampling distributions of X-one when Ho is true (and H1 is false), the other when Hy is true (and Ho is false). The distribution on the left has a mean of yo and represents the sampling distribution of X...
C++ -- Event processing simulation using a transaction queue Hi! it is queue simulation please read the instructions, write codes, and explain the code with comments. Thank you Transactions enter the system and are stored in a queue. Each transaction represents some work that needs to be accomplished. Servers exist which process transactions. Servers take transactions off the queue and process them. you’re building the simulation framework. The idea is that somebody would take your framework, and add the specifics...

Lisa is employed at a long-term care facility. For each shift, there is one nurse on duty for 40 patients. The major nursing responsibility is to give medications to patients. On average, patients have 10 medications each. Lisa must take the blood sugar readings of 10 residents every morning, because they are on sliding-scale insulin orders. The personal support workers provide hands-on care for the patients. Lisa has told her unit manager that she is overworked. She recommends that the...
