Question

Get Data From CSV file and Insert it to Database??????

Asked by: kennethcky

Hi there,

Could anyone tell me if any sample source that can solve my problem?
I would like to get all the data from the CSV file and then insert it to a table in a Database.
The CSV file format is basically same as a table structure.
Example:
ID   FName    LName
1    James     Knite

1)Read and get data in 2 CSV files, by reference to a Field which exists in both CSV file.
2)The data capture will then be inserted into a table in a Database straight away.

Please advice me how I could go about with this....


Any advice appreciated


Thanks in advance

Kenneth

Hi all,

I would like to use pure Java instead of other ready made component/class.

Many thanks

kenneth

>>I would like to use pure Java instead of other ready made component/class.

That's OK. Try using String.split to tokenise the CSV file. Bear in mind that there are gotchas with CSV files, which that API treats

String line = null;
BufferedReader in = new BufferedReader(new FileReader("your.csv"));
while ((line = in.readLine()) != null) {
    String[] tokens = line.split("\\s*,\\s*");
    // Do the insert
}
// Close the Reader

HI,

since my CSV file data are capture from a SQL table, so mean it has Fields name together with its value....SO can I do some filtering like:

when Bac_ID = 1234 then all it's records will be captured and insert into another table in a database

Can I filter that in a CSV file?

Pls advice

Thanks in advance
Kenneth

 

by: CEHJPosted on 2006-01-06 at 01:49:03ID: 15627273

Please print an example of the file

 

by: objectsPosted on 2006-01-06 at 01:49:58ID: 15627277

sure, insdie your loop check the value of the column, and only insert it if it matches.

 

by: kennethckyPosted on 2006-01-06 at 02:51:55ID: 15627494

Output_Filename        | BaC_No    |
____________________________ |
F:\sony\1.txt      | 222        |
F:\sony\2.txt      | 134        |
F:\sony\3.txt      | 123        |
F:\sony\4.txt      | 123        |
----------------------------------------


above is the data format in CSV(excel format).

so if i check "Bac_NO=123" then get all to another table will I able to do that?  will it get row by row?


thanks

 

by: CEHJPosted on 2006-01-06 at 02:55:11ID: 15627511

You just parse it row by row - you *know* what the fields are

 

by: CEHJPosted on 2006-01-06 at 02:56:15ID: 15627517

Insert would look like

ps.setString(1, tokens[0]);
ps.setInt(1, Integer.parseInt(tokens[1]));

 

by: CEHJPosted on 2006-01-06 at 02:56:41ID: 15627519

Sorry

ps.setInt(2, Integer.parseInt(tokens[1]));

 

by: objectsPosted on 2006-01-06 at 03:50:02ID: 15627769

setup your statement

String sql = "INSERT INTO mytable VALUES(?, ?)";
PreparedStatement pstmt = connection.prepareStatement(sql);

then loop thru your file
readLine() will read the next line

then you can parse and chaeck the value

int bac = Integer.parseInt(field[1]);
if (bac==123)
{
   // insert into database

   ps.setObject(1, field(0));
   ps.setInt(2, bac);
   ps.addBatch();
}


once your done you can execute the batch

ps.executeBatch();


heres some more details on batch inserts

Actually I encounter this prb where in my csv files
one of the field actually consists of multiple values.

The 3rd filed in my csv files consists of mulitple values that seperated by "an empty space" or "spacebar".
How am I going to read it and insert it into the table? In each row, one of the field will have mulitple values.

Pls assist me on this prb.

Thanks in advance

Hi above is basically my csv format layout. You possibly can copy and paste into ur Excel Sheet.
The "*" /asterisk is the area where "small box" beside the number is available. (I unable to show the "small box" here so i represent it using "asterisk").

There are 5 fields, and field #3 got 3 sub values on it.

So how am I going to read all this field especially field number 3 which has special character (small box)? Because I gonna append these field's value into db.

I don want to use third party classes.

Thanks

Hope can advice as I desperate for this answer after try n try several times.

>>I don want to use third party classes.

Then i'd advise you to get the Ostermiller source and rewrite it yourself
