Valid styles for converting datetime to string

I wrote this little table and procedure to help me remember what style 104 did, or how to get HH:MM AM/PM out of a DATETIME column. Basically, it populates a table with the valid style numbers, then loops through those, and produces the result (and the syntax for producing that result) for each style, given the current date and time.

It uses also a cursor. This is designed to be a helper function, not something you would use as part of a production environment, so I don’t think the performance implications should be a big concern.

Use CAST (or CONVERT) to handle Null Date values in Microsoft SQL Server

In an SQL Server View, a problem is that the DateTime field has many Null values which is causing a problem with the parsing of the data in MSAccess.

How to I use CAST (or CONVERT) to handle Null Date values in my SQL Server view?

There is a way to use CAST or CONVERT similar to the nz type function in MSAccess to handle null date values but I can’t remember the syntax.

What is happening now is that I get a data mismatch in my MSAccess function when it hits a Null Date value. Can I somehow use the ISNULL or ISDate function? I believe I need to somehow return “” instead of Null.

MS SQL Server / SELECT clause with a CASE expression

In SQL Server, if you have a column which has NULLs and instead of nulls, if you want to display ‘Nothing’, what would you do?

The following query

SELECT CASE Dept_Name WHEN NULL THEN 'Nothing' ELSE Dept_Name END Dept_Name
FROM Inventory

would still display the nulls and not ‘Nothing’.

Workaround:

SQL SELECT INTO Statement

The SQL SELECT INTO statement can be used to create backup copies of tables.

The SQL SELECT INTO Statement

The SELECT INTO statement selects data from one table, creates a new table with the exact structure and size and inserts automatically the selected data into the new table.

SQL SELECT INTO Syntax

We can select all columns into the new table:

SELECT *
INTO new_table_name [IN externaldatabase]
FROM old_tablename

Or we can select only the columns we want into the new table:

SELECT column_name(s)
INTO new_table_name [IN externaldatabase]
FROM old_tablename
