Toad for SQL Server is a SQL Server client with all the features required to access the database, and create and manage database objects. Having created an SQL Server 2017 Express on Windows Server 2012 R2 based Google Cloud Platform VM instance and having installed Toad for SQL Server 6.8 on the same Windows Server, in this article we shall create a database table, add table data, and query the table. We shall also discuss some of the other features including setting the current connection, dropping a table, and dropping a connection. This article has the following sections.
Creating a Database Table with the New Table Wizard
Exploring Database Objects with Explorer
Adding Table Data with SQL Editor
Querying a Table
Dropping a Table
Disconnecting and Reconnecting
Using Multiple Connections
Dropping a Connection
Stopping and Deleting a VM Instance
Closing the RDS Connection
In this section we shall create table wlslog with columns logid, category, type, servername, code and msg. To create a new database table in tempdb database select the Tables tab and click on Create a table as shown in Figure 1.
Figure 1. Create a table
The Create Table wizard gets started, as shown in Figure 2. The Database, Schema and table name must be selected or specified. Default settings are provided for Database and Schema.
Figure 2. Create Table wizard
Specify table name as wlslog and specify primary key column as logid of type int. Select the Not Null checkbox for the logid column and click on Set Primary Key to set the column as a primary key column as shown in Figure 3.
Figure 3. Setting Primary Key Column
Click on Add as shown in Figure 4 to add each of the other columns category, type, servername, code and msg.
Figure 4. Adding columns
The data type in the Type column is selected from the drop-down, as shown in Figure 5. The default data type for each new column is int.
Figure 5. Selecting Datatype
After adding all columns click on OK to create the table, as shown in Figure 6.
Figure 6. Creating Table
The confirmation dialog indicates Table successfully created. The table wlslog gets added to the Object Explorer, as shown in Figure 7.
Figure 7. Table added in Object Explorer
A new table provides several options, which are displayed with a right-click on a table in Object Explorer as shown in Figure 8.
Figure 8. Displaying Table Options
Toad for SQL Server provides the Explorer to explore database objects. Click on Explorer in the toolbar as shown in Figure 9. The Explorer is different from the Object Explorer View which is displayed by default.
Figure 9. Explorer
The Explorer includes its own Object Explorer. The database objects for the tempdb database are displayed in separate categories. Tabs are provided for a database’s Tables, Views and Indexes. Select the dbo.wlslog table in Object Explorer as shown in Figure 10, and tabs for the table’s Columns, Data, Statistics, Indexes, Constraints and other table-related objects get displayed.
Figure 10. Database Table Objects
Select the Columns tab to display the table’s columns as shown in Figure 11.
Figure 11. Table Columns
Select the Data tab to display the table data. Initially the table is empty, as shown by no data being displayed in Figure 12.
Figure 12. Data
In this section we shall add table data to the wlslog table using a SQL Editor. Click on Edit in the toolbar as shown in Figure 13 to launch a SQL Editor.
Figure 13. SQL Edit
Copy and paste the following SQL script in the SQL Editor.
INSERT INTO wlslog(logid,category,type,servername,code,msg) VALUES(1,'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to STANDBY');
INSERT INTO wlslog(logid,category,type,servername,code,msg) VALUES(2,'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to STARTING');
INSERT INTO wlslog(logid,category,type,servername,code,msg) VALUES(3,'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to ADMIN');
INSERT INTO wlslog(logid,category,type,servername,code,msg) VALUES(4,'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to RESUMING');
INSERT INTO wlslog(logid,category,type,servername,code,msg) VALUES(5,'Notice','WebLogicServer','AdminServer','BEA-000361','Started WebLogic AdminServer');
INSERT INTO wlslog(logid,category,type,servername,code,msg) VALUES(6,'Notice','WebLogicServer','AdminServer','BEA-000365','Server state changed to RUNNING');
INSERT INTO wlslog(logid,category,type,servername,code,msg) VALUES(7,'Notice','WebLogicServer','AdminServer','BEA-000360','Server started in RUNNING mode');
Click on Execute SQL to run the SQL script as shown in Figure 14.
Figure 14. Execute SQL
Because AutoCommit is ON by default, the SQL transaction gets committed and data gets added and as the Messages tab in Figure 15 shows, 7 rows affected.
Figure 15. Data Added
The Data tab in the Explorer still does not display the data. Click on Refresh to display the table data added as shown in Figure 16.
Figure 16. Refresh
Table data gets displayed in Data tab, as shown in Figure 17.
Figure 17. Data tab displays data
In this section we shall run a SQL query. Click on Edit in the toolbar to launch another SQL Editor. In the SQL Editor add a SQL query statement (SELECT * FROM dbo.wlslog). The SQL Editor’s code completion feature may be used to select the table, as shown in Figure 18.
Figure 18. Adding SQL Query Statement
Position the cursor at the SQL statement and click on Execute Current Statement to run the SQL statement as shown in Figure 19.

In three articles we have discussed using SQL Server on Google Cloud Platform with Toad for SQL Server. We started by creating a VM instance for SQL Server based on Windows server on Google Cloud Platform and connecting to the VM instance with Chrome RDS. Subsequently we installed Toad for SQL Server 6.8 on the Windows Server and connected to the SQL Server instance running on the Windows server with Toad for SQL Server. We discussed different features of Toad for SQL Server, such as choosing a database, opening and arranging Views, creating a database table, adding table data, exploring database objects, querying table, dropping table, disconnecting and connecting a connection, creating a new connection, and dropping a connection. We also discussed stopping and deleting a VM instance, and closing the Chrome RDS connection. Toad for SQL Server is a client for SQL Server and offers several other features in addition to those explored in these articles.
