Run dbisql in Java Program

Question

I build a Sybase-IQ 16.0 on red-hat 7 server.

I try to use dbisql for bulk load data in Sybase.

And I already successful by command in Sybase server:

dbisql -nogui -c "UID=DBA;PWD=sql;DWN=iqtry;host=172.16.50.137:2643;" -onerror continue READ /EXT_LOAD/Load_Test_Data.SQL

But I need to do this in java program from project requirement, so my program as below:

import java.io.*;
import java.sql.*;
import java.util.*;
import java.sql.Connection;
import java.sql.Date;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class Test {
public static void main(String[] args) throws SQLException {

String dburl = "dbisql -nogui -c 'UID=DBA;PWD=sql;DWN=iqtry;host=172.16.50.137:2643;' -onerror continue READ /sybase/IQ_LOAD/load_DBA.atest.sql";

// Connect to Sybase Database
Connection con = DriverManager.getConnection(dburl);
Statement statement = con.createStatement();
}}

And I can compile in Syabse Server, but when I run this class, I got following error:

Exception in thread "main" java.sql.SQLException: No suitable driver found for

jdbc:sqlanywhere:uid=DBA;pwd=sql;eng=iqtry;database=atest;links=tcpip(host=172.

16.50.137,2643)

at java.sql.DriverManager.getConnection(DriverManager.java:689)

at java.sql.DriverManager.getConnection(DriverManager.java:270)

at Test.main(ConnectIQ.java:30)

From my problem, I have try to set classpath in my current path

set classpath = ./sybase/IQ-16_0/java/sajdbc4.jar

set classpath = ./sybase/IQ-16_0/java/jconn4.jar

But all is can't work.

Answer 1

The dbisql utility is a command line utility and should not be used in conjunction with Java. It is meant to be used through Shells like Bash, or, in a GUI environment.

sajdbc4.jar file is the JDBC driver for SAP IQ. As you've mentioned already about it being in the CLASSPATH , it is better to use its IQDataSource class which implements DataSource Interface from JDBC standard.

A simple code would be:

IQDataSource iqDataSource = new IQDataSource();
iqDataSource.setURL(jdbcUrl);
iqDataSource.setUser(username);
iqDataSource.setPassword(password);

Another hint: remember, each release of SAP IQ ties with a specific build of JDBC driver. Verify you are using the right version target for the right platform.

Hope this helps.
