Few months back I have posted one article on “Javascript: Maximum character validation and character counter for a textbox”, now here I have given one example on how to count words out of any textarea or textbox.

The counter of word will get incremented as you type in each word (one spell) into the textbox/textarea. This script will also work when anyone copy/paste the text into the textbox (copy/paste should not through mouse). Check the following script:

<form id="form1" runat="server">
<asp:TextBox ID="TextBox1" TextMode="multiLine" MaxLength="100"
runat="server" onkeyup="javascript:WordCounter(,'Label1');"
<asp:Label ID="Label1" runat="server" Text="100 chars
<script language="javascript" type="text/javascript">
function WordCounter(textId,lblID)
var this_field = document.getElementById(textId);
var label = document.getElementById(lblID);
var char_count = this_field.value.length;
var fullStr = this_field.value + " ";
var initial_whitespace_rExp = /^[^A-Za-z0-9]+/gi;
var left_trimmedStr = fullStr.replace(initial_whitespace_rExp, "");
var non_alphanumerics_rExp = rExp = /[^A-Za-z0-9]+/gi;
var cleanedStr = left_trimmedStr.replace(non_alphanumerics_rExp, " ");
var splitString = cleanedStr.split(" ");
var word_count = splitString.length -1;
if (fullStr.length <2)
word_count = 0;
if (word_count == 1)
wordOrWords = " word";
wordOrWords = " words";
if (char_count == 1)
charOrChars = " character";
charOrChars = " characters";
label.innerHTML = word_count + wordOrWords;

Happy Coding!!

I have two tables for e.g. tblStudents and tblSchools. Both are having different columns. For a reason I need to merge the two tables into one temporary table.

For example “tblStudents” contains the following design.

StudentID FirstName LastName Address DOB

Where as “tblSchools” contains the following design.

SchoolID Name Address IsSecodarySchool

Now, you would like to merge this two table columns into one temporary table then you can use the following sql script.

SELECT * INTO #tbl_Temp
FROM tblStudent, tblSchool where 1>2

Here, I have mentioned the “where” clause because I wanted to copy only the columns and not the data. You can ignore this clause if you want to copy the entire data too.

You can add as many tables you want to merge by separating with comma (,) between the table names.

You can add specific columns from specific tables by using table alias and column name combination.
For example
SELECT tblStudent.FirstName,tblStudent.LastName,tblSchool.Name INTO #tbl_Temp
FROM tblStudent, tblSchool where 1>2

Happy Programming!
