Microsoft SQL Server - How to check all empty tables in database?

Process to check all empty tables in a Database:

1. Select the database in the SSMS and open the "New Query" window.
2. Run the below query.

SELECT sch.name as SchemaName, t.NAME AS TableName,  p.rows AS RowCounts
FROM   sys.tables t
INNER JOIN  sys.partitions p ON t.object_id = p.OBJECT_ID
INNER JOIN sys.schemas sch on t.schema_id = sch.schema_id
WHERE  t.NAME NOT LIKE 'dt%'   AND t.is_ms_shipped = 0   AND p.rows <=0
GROUP BY  sch.name,t.Name, p.Rows
ORDER BY  sch.name,t.Name

System.InvalidOperationException: 'String[n]: the Size property has an invalid size of 0.'

This error occurs generally when we are not passing the Output parameter in the SqlDbType.VarChar value like the below example

SqlParameter job1 = cmd2.Parameters.Add("@job", SqlDbType.VarChar);
job1.Direction = ParameterDirection.Output;

You need to define a length when specifying SqlDbType.VarChar parameter, So

SqlParameter job1 = cmd2.Parameters.Add("@job", SqlDbType.VarChar, 50);

You should use the same length as defined in your SQL Server stored procedure.

A network-related or instance-specific error occurred while establishing a connection to SQL Server - microsoft sql server error 2

SSMS Error: "A network-related or instance-specific error occurred while establishing a connection to SQL Server"

When you are trying to connect to a SQL Server using Microsoft SQL Server Management Studio, you may see the following message:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that the SQL Server is configured to allow remote connections. (provided: Named Pipes Provider, error: 40- Could not open a connection to the SQL Server) (Microsoft SQL Server, Error: 2).

While the message tells you to check some of the items that can cause this issue, it fails to mention that if your SQL Server Service is not started, then you cannot connect. One of the first things that you should check is that the SQL Server (MSSQLSERVER) is started. You can go to the Services Console (services.msc) and look for SQL Server (MSSQLSERVER) to see that it is started. If not, then start the service.

You could also do this through an elevated command prompt by typing net start mssqlserver.

WooCommerce Order Cancelled After Successful Payment: Unpaid Order Cancelled – Time Limit Reached

In the admin area, all the orders appear as “canceled”  with the message “Unpaid order canceled – time limit reached“. When this happens, you need manually change the statuses of all the canceled orders.

To Resolve the issue, Go to the admin side of your WordPress store, and navigate to

 WooCommerce > Settings > Products > Inventory.

From this page, you can see that the Hold Stock field is set to 60 minutes by default. If you are using WooCommerce stock management, you can disable this feature by leaving the field blank. Simply delete the value in the field and then save the changes.
