TSQL can be used for much more than just creating stored procedures. TSQL is Microsofts implementation of the SQL language. It has Data Definition Language, looping and decision constructs, etc. all of which are ANSI specified.

In addition it supports ANSI specifications for features such as schema exposure separating the user from the base table storage so that schema queries will work in both SQL Server and other ANSI compliant databases. You will see this capability demonstrated in the INFORMATION_SCHEMA views.

So what is not ANSI compliant or transportable. Perhaps items such as User Defined Functions or Table Variables. If you don’t use these kinds of features in your TSQL code it will be transporable and thus ANSI compliant.

TSQL and PL/SQL are supersets of the ANSI standards. To what version fo teh ANSI Standard they comply depends on teh version of the product. This is true of almost any database engine including others such as Sybase, Sybase SQL Anywhere (which us old timers remember as Watcom), MySQL, Posgres SQL, RBASE, Informix…….

SQL is the structured query language. T-Sql is a development environment for creating stored procedures. Every environment needs a way to create batches of SQL statements. Microsoft provides it in the form of T-Sql. Note some commands in T-Sql such as Begin, End, Looping constructs, and others.

I am assuming you mean ANSI SQL regarding the differences. Most database engines today support some level of ANSI compliance.

The problem is (as always) the standards groups lag behind the technalogical needs.

SQL 2k is ANSI compliant for different ANSI Specifications.

Obviously this question is based on your philosophy of software development.
Ask these questions first:

Does your application require operations against more than one database engine?

If so, are you willing to give up performance to go with the lowest common denominator?

If the answer is yes to both the above questions then the question is how to I utilize SQL 2K in an ANSI Compliant fashion. Yes it can be used with ANSI only query methods.
