comma checker

. For example, if a row of msize has 100 comma-separated values, then our incre_table needs to have at least 100 contiguous rows. Of course, MySQL also has a ready-made list of contiguous numbers available. If mysql.help_topic:help_topic_id a total of 504 values, generally can meet the majority of demand. Rewrite as follows: #需要处理的表 CREATE TABLE tbl_name (ID int, msize varchar ()); INSERT into tbl_name values (1, ' tiny,small,big '); INSERT into tbl_

Label:In our daily development, whether it is a table design problem or any other reason, more or less you will encounter a table with a field stored in a comma-separated list of content.Specific effects such as:------》From the diagram on the left to the right, like this demand, we will inevitably encounter.Today I wrote a stored procedure to solve this problem. The main way is to use master. Spt_values table.The specific stored procedures are as foll

Separate each three numbers with a comma in Javascript, and separate the js amount with three commas. Frequently Used in work:Example 1: change the number 1111111 to 11,111,111.00 and retain two decimal places. Example 2: Convert the number 1111111 to 11,111,111 --- and change 11,111,111 to 1111111 --- integer -- The above is all the content of this article. I hope it will be helpful for your learning and easy to format JavaScript amount numbers. Th

consequences. should be cautious.Three. Conditional operators and comma operatorsThe conditional operator is the only "trinocular operator" of the C + + language. It accepts 3 operands, and the operator of the same condition controls the order of evaluation of the expression. Use the following:Expression1?expression2:expression3; (1)(expression1)?　　 (expression2):(expression3); (2)The precedence of the conditional operator is very low, so its operand

Comma-separated expression(Eastvc was published on 9:00:20) The comma-separated expression inherits from C. it is very likely that you often use this expression for-and while-, but in this regard, the language rules are much different from your own intuition. let's take a look at the usage of the comma-separated expression:A single expression can contain multipl

In the past few days, I have read "C ++ programming specifications: http://book.douban.com/subject/1459007/》to the 30th :“to avoid duplicate ,||or, (comma)", and I have never been completely confused. I understand it today. It turns out this is the case:The built-in (logical and), | (logical or) and (comma) operators always meet the following requirements:Evaluate the operands from left to right;For opera

I. Three-mesh operatorTernary operators generally use very little, because it is very poor readability in the program section, so I recommend not to use the ternary operator often, but very little use does not mean not to use, so still have to master its usage, ternary operator expression is as follows:boolean expression? Value 0: value 1Its operation is to return a value of 0 if the result of the Boolean expression is true, and return a value of 1 if the result of the Boolean expression is fals

. And you have to deal with the comma before and after the problem, in short the trouble is a lot of. So let's take a quiet look at the MySQL manual and see if there's any surprises. This time, a function called Find_in_set, will flash the golden light into your eyes. Let's take a look at the definition of this function Copy Code code as follows: Find_in_set (Str,strlist) Returns a value in the range of 1 to n if the string str was

This is the way to implement loops. The following is a specific problem analysis: Length (a.size)-Length (replace (a.msize, ', ', ')) +1 indicates the number of values to be
