Example 3: simple process with complex SELECT statements
The following stored procedure returns all authors (names provided), published books, and publishers from the join of the four tables. This stored procedure does not use any parameters.

storage, strings containing char and varchar data modes may not exist.
The method is compared by LIKE. Understand the storage methods of each data type and the reasons for LIKE comparison failure
Important. In the following example, the local char variable is passed to the stored procedure, and a pattern matching is used to find an author.
. In this process, the author's surname is passed as a variable.
Create procedure find_books @ AU_LNAME char (20) ASSELECT @ AU_LNAME = RTRIM

above 20 MHz, the removal of high-frequency noise is better. It is often advantageous that the power supply enters the Printed Board and a high-frequency capacitance of 1 μF or 10 μF, Which is required even for battery-powered systems.
2 chip configuration decoupling Capacitor
Configure a 0.01 μF ceramic capacitor for each IC chip. A typical decoupling capacitor of 0.1/μF in a digital circuit has a 5 NH distributed inductance, and its parallel resonance frequency is around 7 MHz, that is to say
in programming. Below we will provide different implementation source code for recursion and non-recursion.

Q: Why does ref and out exist in C? (Not in Java)Requirement hypothesis: Now we need to exchange the values of the two variables A and B through a method called swap. A = 1, B = 2 before exchange, asserted: After exchange, A = 2, B = 1.
The encoding is as follows:
Class Program{Static void main (string [] ARGs){Int A = 1;Int B = 2;Console. writeline ("before switching \ TA = {0} \ TB = {1} \ t", a, B );Swap (A, B );Console. writeline ("after switching
Mode operation
After the reset response, the card is in one of the following two operation modes:
--If TA (2) exists, it is in a specific mode;
--If TA (2) does not exist, it is in the negotiation mode.
The figure shows how to select and switch the card operation mode.
1. Specific Mode
In a specific mode, the Protocol indicated by TA (2) should be used directly

, I will refer to the three types of return values of the stored procedure (so that the users who are reading this example do not have to check the syntax ):
1. Return an integer with return2. Return parameters in output format3. recordset
Differences between return values:
Both output and return can be received using variables in a batch program, while recordset is passed back to the client that executes the batch.
