I have a text file that include sql queries.
Each query ends with ";".
I want to execute these queries.
Here is the my problem; i want to read the file until ";" and then execute the query that i have read.
I can read and execute the one-line queries but i can't read whole query that have more than one-line.
Here is the code that i wrote;
try {
String komut = "";
BufferedReader bf = new BufferedReader(new FileReader("C:\\\\Users\\\\AhmetEmre\\\\Downloads\\\\text.txt"));
while ((komut = bf.readLine()) != null) {
if (komut.length() != 0) {
if (komut.charAt(komut.length() - 1) == ’;’) {
komutVektoru.add(komut);
komut = "";
} else {
komut += komut;
}
}
}
Example from text file;

You can use a java.util.Scanner with a file and specify ;
as a delimiter.
Something like this:
Scanner scanner = new Scanner(new File("input.sql"));
scanner.useDelimiter(";");
while(scanner.hasNext()) {
System.out.println("SQL statement: " + scanner.next());
}
Just don't read by line and read by char instead:
int ch;
StringBuilder sb = new StringBuilder();
while ((ch = bf.read()) >= 0) {
if (ch == ';') {
execute(sb.toString());
sb.setLength(0);
} else
sb.append((char)ch);
}
}
