I am new to Java.My Question is I want to create a database instead of querrying a database. What I want to do is I have a list of create statements in a text file Is there anyway by which I can connect to database server and execute these create table statements in my text file.
Example
Database.txt is my file and I have
create table entity {
char Name[3];
int SSN[10];
}
create table ChildEntity {
char childname[4];
}
as the content of txt file

Assuming that your DDL statements are in correct syntax.
You will have to read the database text file and parse it into strings which represent indivual SQL statements.
Store them into an array of Strings.

Now establish a database connection in your program.
[CODE]
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc dbc armeet", "sa", "");
Statement stmt = con.createStatement();
for(int i =0; i<=tableStatements.length; i++)
{
stmt.executeUpdate(s[i]);
}
[CODE]

The easiest thing to do is if your database support batch mode operations.
With MySQL, for example (which is free for download) u can simple write this at the prompt:
mysql -h yourhost -u userid -p < your.txt.file
Enter password; ****
If you need to do this directly from ur java app, the easiest you solution is to spawn a new shell with the this argument:
mysql -h yourhost -u userid -pYoUrPaSsWoRd < your.txt.file
