TSQLScript
==========

This directory shows how to use TSQLScript to run a batch of SQL statements.

TSQLScript can be used to run multiple SQL statements - terminated by ; - after each other.
It is provided by FPC's SQLDB database layer and available in Lazarus.

Notes:
- You must/should have created an empty database on your server/embedded database system first. The scripts will try to create tables and insert sample data. You can also load your own SQL script or paste it in the memo.
- FPC 2.6.x versions currently have a bug that prevents running statements with : in them (e.g. Firebird stored procedure creation). FPC trunk/development version revision 26112 has fixed this..
- All TSQLScript versions (at least up to August 2014) suffer from a bug where comments in Firebird stored procedure and trigger creation scripts cause the script to fail (see http://bugs.freepascal.org/view.php?id=26571). A workaround is to set .CommentsInSQL to false (as is done in the demo) which strips out the comments.
- Firebird DDL (e.g. table creation) and DML (e.g. inserting data) must be separated by a COMMIT. This may also apply to other databases. FPC bug 17829 tracks this, but FPC 2.6.x or trunk currently contains no fix.
A workaround is to split the script into 2, see the sample program.
- The logon form is taken from SQLdb_Tutorial3.

Incidentally, it sets up a database with tables and sample data for the Lazarus wiki tutorials:

(You'll need database clients and a sample database; see the article)
