Toad Edge,Toad Edge 1.0 is the latest offering from Quest Software. Toad Edge is a lightweight and flexible one-stop toolset for open source databases with initial support for MySQL Database, and designed for all the development and management needs of a DBA.
Toad Edge adds support for several features not provided by TOAD for MySQL. Some of the features unique to Toad Edge are support for MySQL 5.7.x, support for Mac OS X, support for JSON with data types and data editor, support for MySQL events, advanced user privilege management, statement run from/to a specification position in a SQL script, SQL diffs and object timestamp-based comparison with detailed schema compare reports, database and filesystem comparison, support for file system synchronization, DevOps features such as team collaboration, CI/CD, Jenkins and automation.
In this article we shall test drive Toad Edge Preview 1.0. Some of the features, such as DevOps feature support for Jenkins, CI/CD and automation are not included in the preview version.
This article introduces Toad Edge and discusses its benefits with MySQL Database as an example. This article has the following sections:
Download the following software (Windows OS or Mac OS X):
-MySQL 5.7 from https://dev.mysql.com/downloads/mysql/.
Install MySQL 5.7. Start the MySQL CLI and list the databases with the show databases command, as we would need to provide a database name when connecting to MySQL from Toad Edge.
Create an AWS account at https://aws.amazon.com/resources/create-account/ to use AWS RDS MySQL.
After downloading the binaries for Toad Edge Preview 1.0, double-click on ToadEdge_1.0_x64_En_Preview.msi and click on Run in Open File. The Toad Edge Setup wizard gets launched. Click on Next as shown in Figure 1.
Figure 1. Toad Edge Setup wizard
Accept the End-User License Agreement and click on Next. Select a destination folder to install Toad Edge and click on Next. Click on Install to start installation. The Installing Toad Edge dialog displays for a few minutes while the software gets installed. When the installation has completed click on Finish.
Select the Toad Edge icon to launch the toolset. If a connection had been previously configured with MySQL database an Enter Password dialog gets displayed as shown in Figure 2. Provide the Password and click on OK.
Figure 2. Specifying Password for MySQL root
The Toad Edge toolset gets launched after verifying connection. The Toad Edge graphical user interface gets launched, as shown in Figure 3.
Figure 3. Toad Edge GUI
Toad Edge provides several Views of which Connections, Object Explorer, and Outline are open by default. All the different Views may be opened from View, as shown in Figure 4.
Figure 4. View
To connect to MySQL database, click on Connect in the toolbar and select New Connection, as shown in Figure 5.
Figure 5. Connect>New Connection
In the New MySQL Connection dialog three tabs are provided to specify the connection parameters: Connection Settings, SSL and SSH. In Connection Settings specify Host (localhost), Database (mysql), User (root) and Password, as shown in Figure 6. The Options Enable AutoCommit and Restore previous work after login are selected by default. We shall be demonstrating committing a transaction with AutoCommit Off,for which the Enable AutoCommit should be de-selected. The Connection Name, which gets auto-generated, must be unique. Connection String Preview lists the connection URL. Click on Test Connection and if the message is “Connection is OK” click on OK.
Figure 6. New MySQL Connection
A new connection gets created and gets listed in Connections view as shown in Figure 7. A SQL worksheet also gets added.
Figure 7. New Connection
If multiple connections are created one of the connections may be selected with Connect Selected, as shown in Figure 8.
Figure 8. Connect Selected
The Object Explorer view lists all the Databases and Users, as shown in Figure 9. The databases listed are information_Schema, mysql, performance_schema and sys with the active database shown in blue as mysql. All the SQL statements run in a worksheet are run on the active database. Setting active database is discussed in a later section.
Figure 9. Object Explorer View
In this section we shall discuss creating a database table using the Worksheet1. Additional worksheets may be added by selecting Worksheet from the toolbar. Specify the following CREATE TABLE SQL statement in the worksheet, as shown in Figure 10, below.
CREATE TABLE wlslog(time_stamp varchar(255) PRIMARY KEY,category varchar(255),type varchar(255),
servername varchar(255), code varchar(255),msg varchar(255));
For DDL (Data definition language) statements such as CREATE TABLE we don’t need to commit the transaction with AutoCommit or by selecting Commit Transaction, since MySQL database implicitly commits the transaction after the statement is run.
Figure 10. Adding CREATE TABLE Statement in Worksheet
Click on Execute SQL Statement as shown in Figure 11.
Figure 11. Execute SQL Statement
As the message Create table processed in Figure 12 indicates, a database table gets created. The AutoCommit Off setting shown below all the view tabs comes into significance when DML statements such as INSERT INTO are run.
Figure 12. Create Table Processed
The wlslog table gets created in mysql database and gets listed in Object Explorer, as shown in Figure 13. The SQL Recall view lists the CREATE TABLEstatement run.
Figure 13. New table wlslog
The MySQL CLI lists the wlslog table with the show tables command, as shown in Figure 14. Select the database with use mysql command before listing tables.
Figure 14. New Table wlslog
Next, we shall run DML SQL statements to add/update data to the wlslog table. The INSERT INTO statement/s may be run in the same SQL Worksheet or a new Worksheet may be opened by selecting Open SQL Worksheet as shown in Figure 15.
Figure 15. Open SQL Worksheet
Add an INSERT INTO statement in the new Worksheet, as shown in Figure 16.
INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:16-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to STANDBY');
Right-click on the SQL Worksheet and select Format to format the SQL, also shown in Figure 16.

Click on Execute SQL Statement as shown in Figure 18 to run the DML statement.
Figure 18. Running SQL Statement
As the message in Figure 19 indicates, one row gets added.
Figure 19. INSERT INTO statement run
As the AutoCommit is Off, the transaction is not yet committed. But the data added gets listed with a SQL query run from a Worksheet, as shown in Figure 20.
Figure 20. SQL Query returns the data added
The INSERT INTO statement has run but not yet been committed to the database. An SQL query on the wlslog table in MySQL CLI does not list any data, as shown in Figure 21.
Figure 21. Table Data not Committed with AutoCommit Off
To commit the transaction click on Commit Transaction as shown in Figure 22.
Figure 22. Commit Transaction
The transaction gets committed and a SQL query in MySQL CLI returns the data added, as shown in Figure 23.
Figure 23. SQL Query in MySQL CLI returns result set after transaction has been committed
Next, we shall demonstrate rolling back a transaction; for which, run another INSERT INTO statement, as shown in Figure 24.
Figure 24. Running another INSERT INTO Statement
Run a SQL query in a Worksheet and two rows of data get returned, as shown in Figure 25.
Figure 25. SQL Query in Worksheet returns two rows
But the second transaction has not yet been committed. To roll back the second transaction, click on Rollback Transaction as shown in Figure 26.
Figure 26. Rollback Transaction
AutoCommit may be enabled by selecting Database>Enable AutoCommit, as shown in Figure 27.
Figure 27. Database>Enable AutoCommit
Next, we shall run multiple SQL statement in a single transaction. In a new Worksheet, add multiple INSERT INTO statements including the statement that was rolled back.
INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:17-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to STARTING');
INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:18-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to ADMIN');
INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:19-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to RESUMING');
INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:20-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000361','Started WebLogic AdminServer');
INSERT INTO wlslog(time_stamp,category,type,servername,code,msg) VALUES('Apr-8-2014-7:06:21-PM-PDT',
'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to RUNNING');
