What is SqlDbType?
SqlDbType: It is used to set the SQL Server Datatypes for a given parameter. ParameterName: It is used to specify a parameter name. Direction: It is used for setting the direction of a SqlParameter. It is Input or Output or both (InputOutput). Size: It is used to set the maximum size of the value of the parameter.
What is the difference between DbType and SqlDbType?
Difference between DbType and SqlDbType is that SqlDbType specifies SQL Server-specific data types while DbType specifies more generic data types. So usage depends on the type of database you are interacting with. Hope this helps.

What is SqlDbType structured?
A special data type for specifying structured data contained in table-valued parameters. It seems my code works with it and without it (pushing table to DB using stored procedure).
What is AddWithValue in C#?
Remarks. AddWithValue replaces the SqlParameterCollection. Add method that takes a String and an Object.

What’s the difference between datetime and DATETIME2?
The main difference is the way of data storage: while in Datetime type, the date comes first and then time, in Datetime2, 3 bytes, in the end, represents date part! Depending on precision, Datetime2 takes between 6 and 8 bytes of storage.
What is the difference between datetime and DATETIME2 in SQL Server?
DATETIME2 has a date range of “0001 / 01 / 01” through “9999 / 12 / 31” while the DATETIME type only supports year 1753-9999. Also, if you need to, DATETIME2 can be more precise in terms of time; DATETIME is limited to 3 1/3 milliseconds, while DATETIME2 can be accurate down to 100ns. Both types map to System.
What is a int in C#?

Characteristics of the integral types
| C# type/keyword | Range | Size |
|---|---|---|
| int | -2,147,483,648 to 2,147,483,647 | Signed 32-bit integer |

| ulong | 0 to 18,446,744,073,709,551,615 | Unsigned 64-bit integer |
What is table valued parameter?
Table-valued parameters are declared by using user-defined table types. You can use table-valued parameters to send multiple rows of data to a Transact-SQL statement or a routine, such as a stored procedure or function, without creating a temporary table or many parameters.
What is table valued function in SQL?
A table-valued function returns a single rowset (unlike stored procedures, which can return multiple result shapes). Because the return type of a table-valued function is Table , you can use a table-valued function anywhere in SQL that you can use a table.
What are the numeric datatypes in SQL Server?
SQL Approximate Numeric category includes floating point and real values. These datatypes in SQL are mostly used in scientific calculations. Here, n is the number of bits that are used to store the mantissa of the float number in scientific notation.
How to set the dbtype of a sqlparameter?
1 You cannot set the DbType property of a SqlParameter to SqlDbType.Date. 2 Use a specific typed accessor if you know the underlying type of the sql_variant. For more information about SQL Server data types, see Data types (Transact-SQL).
How is the sqldbtype linked to the dbtype?
When setting command parameters, the SqlDbType and DbType are linked. Therefore, setting the DbType changes the SqlDbType to a supporting SqlDbType.
What’s the difference between nvarchar and sqldbtype?
Thus SqlDbType.NvarChar becomes a string with a length limiter, while SqlDbType.Money becomes a Decimal type, and so forth. which basically allows a whole number from 0 to 999. How does .Net interpret this?
