you can certainly return a const reference for the assignment opreator, no
matter it is "*this" or "const *this". |

It is account that Funds accumulate for specific disbursment.
For example:
When you have a loan with bank regarding real estate,bank will ask you to
open escrow account to deposit insurance and tax on monthly basis, so you
will have enough fund to pay those bills at the end of year.
opreating account:
This is the account that all major transaction will go through. |

1.1.2 device operation and efficiency
In general, device opreation includes charge injection, transport,
recominbation and emission.
(1). Electron and hole injection.
The interfacial electronic properties are dominant in carrier injection. The
current understanding of how energy barriers form at cathode and anode
interfaces is far from being complete. Work function difference at those
interfaces is not exactly the barrier because of the formation of ultra thin

发帖数: 304 | 11 I want to export the data from SQL based database system, there is about 500
,000 records. Then delete duplicate and invalue records using SAS.
Questions:
1. To store those exported data set, what is the best format file? Split it
to several excel files or just a txt file?
2. How many records a SAS data file can store?
3. To pick up the duplicate records, which include records that is not
exactly duplicate( I mean, sometime one person has two records, however the
name was spelled not exact |

发帖数: 5352 | 12 1.直接用ODBC读成SAS DATA不就行了？再次也是TXT、CSV FILE，一般不用EXCEL。
EXCEL会自动REMOVE LEADING ZEROS
2. AS much as all you can get
3. De-dup by member ID instead of names. |

发帖数: 117 | 13 whatever you can do in SAS, you cao do it in SQL for data manipulation.
so why dont you just do it in the db? |

发帖数: 304 | 14 Thank you, Banzhu!
1. After i did a query, it gave me all the records, however, it only give
me some options to save the data including EXCEL, CSV, HTML, WORD, XML. How
can i use ODBC here? Or just someother where?
2. Great! I like SAS!
3. De-dup by member ID, dose that means I should creat a variable named
memeber ID, that i should use a some method to sign different name different
'memeber ID' value, then de-dup it ? |

IF you have member ID, then use it. If not, you have to de-dup by names
