What is the syntax of a stored procedure in SQL Server?

The syntax for SQL Server stored procedures is as follows:

1. Create a stored procedure.
2. Define a stored procedure with the specified name and optional parameters, encryption, recompilation, or execution clause.
3. Definition of parameters:
4. Input Parameter: @parameter_name data_type [= default_value] [READONLY]
5. Output parameter: @parameter_name of data_type [OUTPUT]
6. Table-valued parameter: @parameter_name with the type READONLY
7. Execute a stored procedure.
8. Call the stored procedure with the specified schema name, procedure name, and parameters.
9. Remove stored procedure:
10. Delete the procedure named [schema_name.]procedure_name.

In the main body of a stored procedure, various SQL statements such as SELECT, INSERT, UPDATE, and DELETE can be used to perform the required operations. In addition, control statements (such as IF, WHILE, BEGIN…END) and exception handling statements (such as TRY…CATCH) can also be used to implement more complex logic.
