In oracle, the question of processing comma-separated fields using regular expression functions is really not easy to write. Its actual meaning is based on a scenario: www.2cto.com, for example, in an oracle table, there are two fields A1 B1 1 A, B, C, D, 2 E, F. If the current requirement is to count the number of B1, for example, when A1 = 1, there are four fields in B1 separated by commas. Therefore, if the number is 4 and A1 = 2, there are two fie

The following small series for you to share a text based on the echo in PHP with a comma and the difference between the number of points, with a good reference value, I hope to help you. Let's take a look at it with a little knitting. Examples are as follows: The results are as follows: The above based on the echo in PHP and the difference between the comma and the dot is a small part of the whole cont

This error occurred today when executing an SQL script for an Oracle stored procedure, in fact the reason is simple, not the missing comma as indicated by the hintThe original SQL statement is longer, here will not paste the original statement, mainly such a sentenceINSERT into * * * VALUES (' * * * and ((B.credit_asset_flag = ' 3 ') OR(B.credit_asset_flag = ' 0 ' and c.balance_type = ' 1 ') ');B.credit_asset_flag = ' 3 ' Here should be two single quo

usually with Number_format (); To format a number, by default the thousand characters are separated by commas, such as: Copy CodeThe code is as follows: Echo Number_format ("10000.01231", 2); Take 2 digits after the decimal point, the result of the output is: 10,000.1000 bits default is comma interval. It would be a bit of a struggle if we were to verify that the numbers obtained from the client were in the background. Lao Tong commonly used Filte

Today, I saw the comma operator in the group. Let's sum up my understanding of it. Don't spray it! (PS: It has been a long time since the discussion. I saw it just now !! Nima !) Comma OPERATOR: executes the expression in order and obtains the value of the expression on the right. Here is an example: VaR A = 10; var B = 20; var c = (a ++, B ++, 100); console. log (a); console. log (B); console. log (C );

When we traverse the concatenated string, an additional character (such as a comma) will be added ). Method 1: String STR [] = {"hello", "Beijing", "world", "Shenzhen"}; stringbuffer Buf = new stringbuffer (); For (INT I = 0; I Method 2: Stringbuilder SDB = new stringbuilder (); For (int t = 0; t Remove the last extra comma when splicing a string

Recently done a JS project, need to put the number according to every three bits, with a comma separated, done, I think, this algorithm can also support user-defined number of bits, to separate, is the use of regexp this method to splice strings, so that it has a dynamic separation of functions.On the code:function Numberdivid (number,n) {var n = n | | 3;//set default var reg = new RegExp ("(\\d+)" + "(\\d{" +n+ "})");//string concatenation, Bring n i

[Note] JavaScript coding specifications-comma and semicolon, and javascript semicolon Do not use a comma before a statement. // Badvar story = [once, upon, aTime]; // goodvar story = [once, upon, aTime]; Do not include extra commas: this will cause some problems in the weird modes of IE6, IE7, and IE9. At the same time, in some implementations of ES3, extra commas will increase the length of the array.

During system creation, multiple information is stored in a field separated by commas (,) or other symbols. For example, when one user's one-to-multiple permission is saved, in the permission group field, multiple permission numbers are separated by commas. Now, if a permission number is provided and you want to retrieve the user set with the permission, you need to match the given permission number among multiple permission numbers separated by commas. If you use like, one is less efficient, a

The simulation terminal securecrt I use requires a script that supports vbs. I need to implement the following functions:First, the text file is in: D: \ 100.txtThe text file content is:9 0, Randy,9 1, Jeff,9 2, sameul,Now we need a loop to automatically execute related parameters. The loop needs to call two variables TN and name.Assign the value before the first comma to TN and the parameter before the second com
