vb.net - search for a word in entire table - MySQL -

-

Currently using the following code to search for a word in the entire table, 

  String = "sample" as a slow search string as mysql = "SELECT * FROM myTable" & amp; _ "Where '%' as the call 1 & amp; Search & amp; "% '" & Amp; _ "Or '%' like call 2 & amp; Search & amp; "% '" & Amp; Like "_" or 3 as'% '& amp; Search & amp; "%'" & Amp; _ "or call 4 & quot; & quot; & amp;"% & quot; "

but increases the number of columns but if the query becomes more difficult, then anyone can suggest some alternative methods to do this.

Use a loop to make your string a program In this example, you only need to add your column to the array. 

  forms of retarded form In the form of the string = = "sample" = dimension (string) = {"col1", "col2", "col3", "col4"} as blurted boolean = true dull mysql string = "select * from myTable WHERE "Arrays in the string for each string if b mysql = mysql & str +" such as '% "& amp; Search and"%' "Other Mysql = mysql & amp;" or "& Str & Amp; "Preferences '%" & Search & amp; "%'" End if B = False Forwarded Debug. Published (mysql)

Output >>

< Pre> SELECT * myTable where '% sample%' like call 1 or '% sample' like 'call 2' or '3% Sample% 'or 3 like'% sample ''

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
