CSQL Interpreter¶

The CSQL Interpreter is a program used to execute the SQL statements and retrieve results in a way that CUBRID supports. The entered SQL statements and the results can be stored as a file. For more information, see Introduction to the CSQL Interpreter and CSQL Execution Mode.

CUBRID also provides a GUI-based program called "CUBRID Manager". You can execute all SQL statements and retrieve results in the query editor of CUBRID Manager. For more information, see Management Tools.

This section describes how to use the CSQL Interpreter on the Linux environment

Starting the CSQL Interpreter

You can start the CSQL program in the shell as shown below. At the initial installation, PUBLIC and DBA users are provided and the passwords of the users not set. If no user is specified while the CSQL Interpreter is executed, PUBLIC is used for log-in.

Running SQL with CSQL

After the CSQL has been executed, you can enter the SQL into the CSQL prompt. Each SQL statement must end with a semicolon (;). Multiple SQL statements can be entered in a single line. You can find the simple usage of the session commands with the ;help command. For more information, see Session Commands.

Running SQL with CUBRID Manager¶

CUBRID Manager is the client tool that you should download and run. It is a Java application which requires JRE or JDK 1.6 or higher.

1. Download and install the latest CUBRID Manager file. CUBRID Manager is compatible with CUBRID DB engine 2008 R2.2 or higher version. It is recommended to upgrade to the latest version periodically; it supports the auto-update feature. (CUBRID FTP: http://ftp.cubrid.org/CUBRID_Tools/CUBRID_Manager )

2. Start CUBRID service on the server. CUBRID Manager server should be started for CUBRID Manager client to access to DB. For more information, see CUBRID Manager Server.

   C:\CUBRID>cubrid service start
   ++ cubrid service is running.
   

3. After the installation of CUBRID Manager, register host information on the [File > Add Host] menu. To register the host, you should enter host address, connection port (default: 8001), and CUBRID Manager user name/password and install the JDBC driver of the same version with DB engine (supporting auto-driver-search/auto-update).

4. Choose the host on the left tress and perform the CUBRID Manager user (=host user) authentication. The default ID/password is admin/admin.

5. Create a new database as clicking the right mouse button on the database node, or try to connect as choosing the existing database on the bottom of the host node. At this time, do the DB user's login. The default db user is "dba", and there is no password.

6. Run SQL on the access DB and confirm the result. The host, DB and table list are displayed on the left side, and the query editor and the result window is shown on the right side. You can reuse the SQLs which have been succeeded with [SQL History] tab and compare the multiple results of several DBs as adding the DBs for the comparison of the result with [Multiple Query] tab.

   

Migrating schema/data with CUBRID Migration Toolkit¶

CUBRID Migration Toolkit is a tool to migrate the data and the schema from the source DB (MySQL, Oracle, and CUBRID) to the target DB (CUBRID). It is also Java applications which require JRE or JDK 1.6 or later. You should download separately. (CUBRID FTP: http://ftp.cubrid.org/CUBRID_Tools/CUBRID_Migration_Toolkit )

It is useful in case of switching from other DB into CUBRID, in case of migrating into other hardware, in case of migrating some schema and data from the operating DB, in case of upgrading CUBRID version, and in case of running the batch jobs. The main features are as follows:

• Supports the tools/some schema and data migration
• Available to migrate only the desired data as running several SQLs
• Executable without suspending of operation as supporting online migration through JDBC
• Available offline migration with CSV, SQL, CUBRID loaddb format data
• Available to run directly on the target server as extracting the run-script of migration
• Shorten the batch job time as reusing the migration run-script.
