The simplest way to import csv file content into MYSQL table. Before import, make sure that the table is created or not.

Syntax:

load data local infile ‘
‘ into table
fields terminated by ‘,’
lines terminated by ‘\n’
(tbl_column_name1,tbl_column_name2,tbl_column_name3,…,tbl_column_name N);

Where,

is a current CSV file location,is name of the table, you import contents into this table.

tbl_column_name1,tbl_column_name2,tbl_column_name3,…,tbl_column_name N these are the column-names of a specified table.
[import CSV content into these column fields]

For example:

load data local infile ‘C:\\Data\\Accountants.csv’ into table tbl_Data
fields terminated by ‘,’
lines terminated by ‘\n’
(jbl_CategoryID, jbl_BusinessName, jbl_Address, jbl_City, jbl_State, jbl_PinCode, jbl_BusinessPhone1, jbl_BusinessPhone2);

This command you can execute in MYSQL query window or Resultset window.

How to get specified div tag content from an html page in asp.net?

The simple and easiest way is “Regular expression”. My source content type is an html format data’s. So I want to scarp the div tag content only from source content and that div tag id is called as “divcontent1”. I created one small function is called “ScrapDivtagContent”. The function definition is here,

Sub function ScrapDivtagContent(strSource as string) as String

Dim mt As Match = Regex.Match(strSource, “[\s\S]*?”, RegexOptions.Multiline)

Return mt.Value.Trim

End sub

Note:

The div content id should be unique.
