Script support

Q: Does Jaybird support script execution?

A: No, currently Jaybird does not support script execution. You have either to call isql from Java code through Runtime.exec(...) call or you parse the script yourself and submit each command separately. In latter case pay attention to SET ... commands, especially to SET TERM.

Simple script executor can look like this:

importjava.sql.Connection;
importjava.io.IOException;
importjava.sql.SQLException;
importjava.io.Reader;
importjava.sql.Statement;
publicclassScriptExecutor {
publicstaticfinalStringDEFAULT_SET_TERM = "SET TERM";
publicstaticfinalStringDEFAULT_TERM = ";";
privateStringsetTermCommand = DEFAULT_SET_TERM;
privateStringterm = DEFAULT_TERM;
publicScriptExecutor() {
}
publicScriptExecutor(StringdefaultTerm, StringsetTermCommand) {
this.term = defaultTerm;
this.setTermCommand = setTermCommand;
}
publicvoidexecuteScript(Connectionconnection, Readerin)
throwsSQLException, IOException {
StringBuffersb = newStringBuffer();
Statementstmt = connection.createStatement();
try {
intch = 0;
while ((ch = in.read()) != -1) {
sb.append((char)ch);
StringpossibleTerm = sb.substring(sb.length() - term.length());
if (possibleTerm.equals(term)) {
Stringcommand = sb.substring(0, sb.length() - term.length()).trim();
processCommand(stmt, command);
}
}
} finally {
stmt.close();
}
}
protectedvoidprocessCommand(Statementstmt, Stringcommand) throwsSQLException, IOException {
if (command.toUpperCase().startsWith(setTermCommand)) {
term = command.substring(setTermCommand.length()).trim();
} elsestmt.execute(command);
}
}
