Analysis of ifelse in Mysql stored procedure
An error is reported when writing the following code:
[Error] 1064-You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near
In development, if {} else {} is often used. Sometimes more than N is nested, which sometimes causesCodeLooks messy. Next we will introduce a simple ifelse method:
If (is = true ){
Is = false;} Else {
Is = true;
}
This code is simple, but
MySQL stored procedure example. you cannot use beginend in ifelse. Otherwise, the error ErrorCode: 1064 is reported to solve bitsCN.com.

In this way, an error can occur when writing an ifelse statement ????? I was going to embed this piece of code into a php script, but it always prompts an error: Parse & nbsp; error: & nbsp; syntax & nbsp; error, & nbsp; unexpected & nbsp; T_ELSE &

We have a,b,c,d four different categories, at the very beginning there are only three categories, and two categories are doing the same thing:1 function Categoryhandle (category) {2 if (Category!== ' A ') {3 console.log (' B, C '); 4
C # if, ifelse statement,
1. The if statement is determined based on the value of the Boolean expression.
The if statement can be either of the following methods:
Code(1)if(boolean) do (2)if(boolean){ do}
Generally, the second method is used,

I. Ordered Workflow
Ordered activities are the most basic and simple container-type activities in WWF workflows. Ordered activities can be used as branches of many other activities.
Code:
Private void codeexecute1 (Object sender, eventargs e)
There are two methods for workflow in WF: code mode and code mode. the xoml mode, the two can be converted to each other, which is the serialization provided in WF.And deserialization support. The following important classes in the WF framework:
