Hi,

I need to update a cursor based on the values in an array. I know I can do it by scanning through the cursor or scanning through the array and checking each element. But I was wondering if there is SQL command to do it. The following are the structure and sample of the cursor and the array:
*-- cursor
*-- strucutre
column        value
*-- record 1
PK                333
WEEK_NO    12
WEEK_FR      1
WEEK_TO     52
*-- record 2
PK                4
WEEK_NO    45
WEEK_FR      2
WEEK_TO     23
*-- and so on

*-- array
local array aSchedule[2,4]
*-- element 1
aSchedule[1,1]  = 333   && corresponding to the column PK in the cursor
aSchedule[1,2]  = 3       && corresponding to the column WEEK_NO in the cursor
aSchedule[1,3]  = 1       && corresponding to the column WEEK_FR in the cursor
aSchedule[1,4]  = 45       && corresponding to the column WEEK_TO in the cursor
*-- element 2
aSchedule[1,1]  = 4        && corresponding to the column PK in the cursor
aSchedule[1,2]  = 3       && corresponding to the column WEEK_NO in the cursor
aSchedule[1,3]  = 1       && corresponding to the column WEEK_FR in the cursor
aSchedule[1,4]  = 45      && corresponding to the column WEEK_TO in the cursor
TIA
