Comparing between rows in same table in Oracle

由 China☆狼群 提交于 2019-12-13 00:29:05
问题 I am trying to find the best way to compare between rows in the same table. I wrote a self join query and was able to pull out the ones where the rates are different. Now I need to find out if the rates increased or decreased. If the rates increased, it's an issue. If it decreased, then there is no issue. My data looks like this ID DATE RATE 1010 02/02/2014 7.4 1010 03/02/2014 7.4 1010 04/02/2014 4.9 2010 02/02/2014 4.9 2010 03/02/2014 7.4 2010 04/02/2014 7.4 So in my table, I should be able

compare 8bit value against 16bit value

由 限于喜欢 提交于 2019-12-12 23:23:07
问题 I was wondering what happens when an 8bit value is compared against a 16bit value. I'll try to explain the problem by a code example: bool result; unsigned char a_8bit = 0xcd; unsigned short b_16bit = 0xabcd; result = a_8bit < b_16bit; Possible results can be: a_8bit is casted to unsigned short implicitly and compared to b_16bit as a 16bit value. Result is true b_16bit is casted to unsigned char implicitly and compared to a_8bit as an 8bit value. Result is false Does anybody has a clue what

MIPS how can you compare a character taken from input?

由 Deadly 提交于 2019-12-12 19:04:26
问题 My program asks the user if the number he/she is thinking of is in a list. The user inputs a y or an n. How can I check if a user has entered y or n in assembly? Is it sufficient to put the user input into a register and branch if equal to 121 (decimal ASCII code for 'y') or branch if the value is equal to 110 (decimal ASCII code for 'n'? Thanks in advance 回答1: One can use the system call code for Read Character, which should be system call code 12, then the character (binary ASCII code) will

comparing two floats to see if they're both negative, or both positive

由 久未见 提交于 2019-12-12 18:58:46
问题 Hay guys, i have 2 floats, which both comes from input boxes. I need to compare these 2 floats, if one is negative and one is positive thrown an error. If they're both positive, or both negative, thats fine. Any ideas? Thanks 回答1: Multiply them together. If the answer is positive then they are both the same sign. If the answer is negative then they are of opposite sign. If the answer is zero (within some value to take care of rounding error) then one or both are zero and you'll have to check

Comparing Oracle Forms modules

由 不羁岁月 提交于 2019-12-12 17:19:50
问题 We've inherited a large Oracle project that was originally Oracle 9 and is now Oracle 11. We don't have much confidence in the Forms change register. Are there any tools we could use to compare the two Forms projects? (By virtue of the fact that two different versions of Forms are involved, there will be differences even though the underlying code hasn't changed). 回答1: The general consensus of the Oracle Tools Developers Users Group is that the ORCL Toolbox FormsTool diff ability is the best

问题 I'm currently working in a project, where I need to compare these two arrays and filter out the ones with same room name; (for example; A420.2 - 0h 53 m (from vacant -array) and A420.2 (from booked -array)). var vacant = [ A210.3 - 0h 53 m ,A510.2 - 0h 53 m ,A510.4 - 0h 53 m ,A340.2 - 0h 53 m ,A420.2 - 0h 53 m ,A450.1 - 1h 53 m ,A250.1 - 1h 53 m ,A520.7 - 2h 53 m ,A510.2 - 2h 53 m ,A240.2 - 2h 53 m ,A440.2 - 2h 53 m ,A350.1 - 4h 38 m ,A250.1 - 4h 53 m ,A450.3 - 4h 53 m ,A340.1 - 4h 53 m ,A320

Comparing the contents of two lists in prolog

问题 I am having some kind of homework and I am stuck to one point. I am given some facts like those: word([h,e,l,lo]). word([m,a,n]). word([w,o,m,a,n]). etc and I have to make a rule so that the user will input one list of letters and I should compare the list with the words I have and correct any possible mistakes. Here is the code I am using if the first letter is in the correct place: mistake_letter([],[]). mistake_letter([X|L1],[X|L2]):- word([X|_]), mistake_letter(L1,L2). The problem is I

Using Collections to sort values

由 人盡茶涼 提交于 2019-12-12 16:09:13
问题 Using Collections to sort is nifty, a lot better for me than using Comparator since i have multiple values that are the same and i'd rather them not be just thrown out to the trash. But Collections has it's own issue, it seems to think repeating numbers of groups of 2+ to be smaller than their actual smaller counter parts Example have these keys and values("katy 1","mark 9","john 2","alice 11","josiah 22","chris 44") and it sorts them as follows alice 11 katy 1 john 2 josiah 22 chris 44 mark
