You can use the OBJECTPROPERTY() function in SQL Server to check whether an object is a table-valued function or not.
To do this, pass the object ID as the first argument, and IsTableFunction as the second argument. The function returns a 1 or a 0 depending on whether or not it’s a table-valued function.
A return value of 1 means that it is a table-valued function, and a value of 0 means that it’s not.
The OBJECTPROPERTY() function in SQL Server enables you to check an object for a specific property.
You can use this function to check whether an object is a system table or not. To do this, pass the object ID as the first argument, and IsSystemTable as the second argument. The function returns a 1 or a 0 depending on whether or not it’s a system table (1 means that it is a system table, and 0 means that it’s not).
You can use the OBJECTPROPERTY() function in SQL Server to check whether or not an object is a primary key.
To find out whether an object is a primary key, pass the object ID as the first argument, and IsPrimaryKey as the second argument. The function returns a 1 or a 0 depending on whether or not it’s a primary key.
A return value of 1 means that it is a primary key, and a value of 0 means that it’s not.
You can use the OBJECTPROPERTY() function in SQL Server to find out whether or not an object is a foreign key.
To find out whether an object is a foreign key, pass the object ID as the first argument, and IsForeignKey as the second argument. The function returns a 1 or a 0 depending on whether or not it’s a foreign key.
A return value of 1 means that it is a foreign key, and a value of 0 means that it isn’t.
You can use the OBJECTPROPERTY() function in SQL Server to find out whether or not an object is a view.
This function accepts two parameters: the object ID, and the property for which you’re checking it for.
Therefore, you can pass the object ID as the first argument, and IsView as the second, and the function will return either a 1 or a 0 depending on whether or not it’s a view.
A return value of 1 means that it is a view, and a value of 0 means that it’s not.
In SQL Server you can use the OBJECTPROPERTY() function to find out whether or not an object is a stored procedure.
This function accepts two parameters: the object ID, and the property for which you’re checking it for.
Therefore, you can pass the object ID as the first argument, and IsProcedure as the second, and the function will return either a 1 or a 0 depending on whether or not it’s a stored procedure.
A return value of 1 means that it is a stored procedure, and a value of 0 means that it’s not.
In SQL Server you can use the OBJECTPROPERTY() function to find out whether or not an object is a CHECK constraint.
This function accepts two parameters: the object ID, and the property for which you’re checking it for.
Therefore, you can pass the object ID as the first argument, and IsCheckCnst as the second, and the function will return either a 1 or a 0 depending on whether or not it’s a CHECK constraint.
A return value of 1 means that it is a CHECK constraint, and a value of 0 means that it’s not.
Below are five methods you can use to quickly determine how many user-defined tables are in the current database in SQL Server.
All five options use the COUNT() function to get the count. Obviously, you can replace this with an asterisk (*), or the names of the columns to return a list of all user-defined tables.
Here’s an article that presents three ways to quickly determine how many system tables are in the current database in SQL Server.
All three options use the COUNT() function while querying the sys.objects system catalog view. They all result in the same output, so you really don’t need to go past the first option. But I’ll list them anyway.
This article offers five options for checking if a table exists in SQL Server. Most options involve querying a system view, but one of the options executes a system stored procedure, and another involves a function.
I also include some simple IF statements that can be modified to suit your circumstance.
