the view layer, and processing some of the logic of the page interaction;4, when a function is to design remote API calls, datasets, business Insight complex logic, will be a large number of repeated operations, you can consider the code as a service injection controller layer.5. The $scope in the controller is the only source of page data. Do not modify the DOM directly.6, controller do not in the global scopeReference article:http://www.jianshu.com

In MySQL data types, such as INT, FLOAT, DOUBLE, CHAR, and DECIMAL, they all have their respective functions, next we will mainly introduce the role and usage of the DECIMAL type in the MySQL data type. Generally, the value of the floating point column is rounded to the specified decimal number. If 1. 2 3 4 5 6 is stored in a FLOAT (8, 1) column, the result is 1.

In the real online environment, there will be a steady stream of new requests coming in, the current

Then (Successfunc, Failurefunc);If then () has two parameters, then the first parameter i

BCP is generally stored in the BIN directory of the installed ASE or Open Client. For ASE earlier than version 12, the bcp directory is $ SYBASE/bin, and for Versions later than Version 12 (including version 12), the directory is $ SYBASE/OCS-12_x/bin. $ SYBASE is the SYBASE installation directory. 12_x represents versions 12.0 and 12.5 and is displayed as 12_0 or 12_5. the executable file name is bcp. EXE. The parameter list is as follows:(Available bcp-available)

greatly improve the query speed. Example: Selectsum (A.amount) from account A, CARD B WHERE a.card_no=b.card_no selectsum (a.amount) from account A,card B WHERE a.card_no=b.card_no and a.account_no=B.account_no The second sentence will be much faster than the first sentence. -. Use a view-accelerated query to sort a subset of tables and create views, sometimes speeding up queries.　　It helps to avoid multiple sorting operations, and in other ways simplifies the work of the optimizer. +.

The c ++ operator has two usage methods: heavy-load and implicit type conversion. string is a concise implementation of string_cast to convert other basic data types.Operator in C ++ has two main functions: one is operator Overloading and the other is implicit conversion of custom object types. Many people are familiar with operator overloading, but many people are not familiar with operator's second
