Using DBF_JDBC30
Magna
2007-04-25 13:44:05.0
Hello:
I am using DBF_JDBC30.jar . I would like to know how can I create a .dbf file which can be read from MSExcel.
Thanks

At Connecting to the Database, use versionNumber=03 connection property.

When I set my properties:
Properties properties = new Properties();
properties.setProperty("versionNumber", "03"); //also tried with:04,30,40
properties.setProperty("DefaultExtension","dbf");

But in Excel i have this message before it opens the file: "The file is not in a recognizable format"....

The new created dbf file should be able to open by your MS Excel. The older created dbf file without that versionNumber can't be open. But you can use "create table newtable select * from oldtable" to create DBASE III talbe.

The file, indeed can be opened by MSExcel but after the message "The file is not in a recognizable format".... MSExcel opens the file but not normally as it always does to a dbf file. It shows in the sheet something like this:

properties.setProperty("DefaultExtension","dbf");
//properties.setProperty("lockType", "DBASE4");

try {

Passed test with the following code. What's your OS language? You can try:
properties.setProperty("charSet", "yourCharSet");




import java.sql.*;
import java.util.Properties;

public class testDBFExcel16 {
public static void main(String argv[]) {
String strDefaultOutputDir="d:/test/lib";
String strNewOutputTable="myTable";
Connection conOutputFile;
Statement stOutputFile;
String strSQLCols="\"ID\" VARCHAR (25), \"NAME\" VARCHAR (25),\"VALUE\" NUMERIC (4,1)";
try {
Class.forName("com.hxtt.sql.dbf.DBFDriver").newInstance();
String urltable = "jdbc:dbf:///" + strDefaultOutputDir + "";
Properties properties = new Properties();
properties.setProperty("versionNumber", "03");
properties.setProperty("DefaultExtension", "dbf");
//properties.setProperty("lockType", "DBASE4");

conOutputFile = DriverManager.getConnection(
urltable,
properties);
stOutputFile = conOutputFile.createStatement();
stOutputFile.execute("CREATE TABLE if not exists " + '"' +
strNewOutputTable + '"' + " (" + strSQLCols +
")");
stOutputFile.close();
conOutputFile.close();

stOutputFile.close();
conOutputFile.close();
}
catch (SQLException sqle) {
do {
System.out.println(sqle.getMessage());
System.out.println("Error Code:" + sqle.getErrorCode());
System.out.println("SQL State:" + sqle.getSQLState());
sqle.printStackTrace();
}
while ( (sqle = sqle.getNextException()) != null);
}
catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
}

If your issue exists still, please email us your dbf sample.

BTW, because there's "if not exists" clause, you should remove manually myTable.dbf if you repeat your test.

Thank you for the code. i have tried with your example code and it created the table well, but when i opened it in Excel, same problem. The language of my OS is english.
I read something like this in the first line of the Sheet : "0kˆ7IDCNAMECVALUEN3"
I am enclosing the code of the code example i used to this new try (i will email you my .dbf file i got):

import java.sql.*;
import java.util.Properties;

public class MyCreateTable {

public static void main(String argv[]) {

String strDefaultOutputDir="D:/instalados/eclipse/workspaceDIVA2007_RC8/GridIO";
String strNewOutputTable="myTable";
Connection conOutputFile;
Statement stOutputFile;
String strSQLCols="\"ID\" VARCHAR (25), \"NAME\" VARCHAR (25),\"VALUE\" NUMERIC (4,1)";

try {
Class.forName("com.hxtt.sql.dbf.DBFDriver").newInstance();
String urltable = "jdbc:dbf:///" + strDefaultOutputDir + "";
Properties properties = new Properties();
properties.setProperty("versionNumber", "03");
properties.setProperty("DefaultExtension", "dbf");
//properties.setProperty("lockType", "DBASE4");
conOutputFile = DriverManager.getConnection(
urltable,
properties);

stOutputFile = conOutputFile.createStatement();
stOutputFile.execute("CREATE TABLE if not exists " + '"' +
strNewOutputTable + '"' + " (" + strSQLCols +
")");
/* stOutputFile = conOutputFile.createStatement();
stOutputFile.execute("INSERT INTO " +strNewOutputTable+" (ID, NAME, VALUE) VALUES ('a','a',2.50)"); */

stOutputFile.close();
conOutputFile.close();
stOutputFile.close();
conOutputFile.close();
}

catch (SQLException sqle) {
do {
System.out.println(sqle.getMessage());
System.out.println("Error Code:" + sqle.getErrorCode());
System.out.println("SQL State:" + sqle.getSQLState());
sqle.printStackTrace();
}

while ( (sqle = sqle.getNextException()) != null);
}

catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
}

Checked, and found your issue:

You should remove your myTable.dbf file manually, then run your test case again. I found that your sample is using VFP format. I runned your MyCreateTable.java and got a DBASE III format:)

I did that , but have the same issue. And when i tried to save the created file from Excel to dbf3 format, for example, i lose data.

I also tried this (of course, first I delete manually the previous file):
import java.sql.*;

import java.util.Properties;
public class MyCreateTable2 {

/**
* @param args
*/
public static void main(String[] args) {
String strDefaultOutputDir="D:/instalados/eclipse/workspaceDIVA2007_RC8/GridIO";

String strNewOutputTable="example1";

Connection conOutputFile;

Statement stOutputFile;

String strSQLCols="\"ID\" VARCHAR (25), \"NAME\" VARCHAR (25),\"VALUE\" NUMERIC (4,1)";

try {

Class.forName("com.hxtt.sql.dbf.DBFDriver").newInstance();

String urltable = "jdbc:dbf:///" + strDefaultOutputDir + "";

Properties properties = new Properties();

//properties.setProperty("versionNumber", "04");

properties.setProperty("DefaultExtension", "dbf");

properties.setProperty("lockType", "DBASE4");



conOutputFile = DriverManager.getConnection(

urltable,

properties);

stOutputFile = conOutputFile.createStatement();

stOutputFile.execute("CREATE TABLE " + '"' +

strNewOutputTable + '"' + " (" + strSQLCols +

")");

stOutputFile.close();

conOutputFile.close();



stOutputFile.close();

conOutputFile.close();

}

catch (SQLException sqle) {

do {

System.out.println(sqle.getMessage());

System.out.println("Error Code:" + sqle.getErrorCode());

System.out.println("SQL State:" + sqle.getSQLState());

sqle.printStackTrace();

}

while ( (sqle = sqle.getNextException()) != null);

}

catch (Exception e) {

System.out.println(e.getMessage());

e.printStackTrace();

}

}

}

I tried your code, and MS Excel can open it. Your DBASE III sample should be opend by MS Excel. If you failed, please email me the dbf sample. The received sample is VFP format, and I can recur your issue:)


>//properties.setProperty("versionNumber", "04");
You should remove the //, but I guess that MS Excel maybe don't know DBASE IV format.

>properties.setProperty("DefaultExtension", "dbf");
You needn't to set that default value.

>properties.setProperty("lockType", "DBASE4");
Wrong. It hasn't any relation with database format. It's used for lock type. You can mask that line.

String strSQLCols="\"ID\" VARCHAR (25), \"NAME\" VARCHAR (25),\"VALUE\" NUMERIC (4,1)";

try {

Class.forName("com.hxtt.sql.dbf.DBFDriver").newInstance();

String urltable = "jdbc:dbf:///" + strDefaultOutputDir + "";

Properties properties = new Properties();

conOutputFile = DriverManager.getConnection(

urltable,

properties);

stOutputFile = conOutputFile.createStatement();

stOutputFile.execute("CREATE TABLE " + '"' +

")");

stOutputFile.close();

conOutputFile.close();



stOutputFile.close();

conOutputFile.close();

}

catch (SQLException sqle) {

do {

sqle.printStackTrace();

}

Wrong. It should be:
Properties properties = new Properties();
properties.setProperty("versionNumber", "03");
conOutputFile = DriverManager.getConnection(urltable,properties);
