kandi X-RAY | HyperSQL Summary

HyperSQL is a Python library typically used in Database, SQL Database applications. HyperSQL has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. However HyperSQL build file is not available. You can download it from GitHub.

HyperSQL is like a doxygen plus javadoc for SQL, hypermapping SQL views, packages, procedures, and functions to HTML source code listings and showing all code locations where these are used, while some basic syntax highlighting is applied to the SQL code. The internal "where used" functionality also scans C++ and Java source files. HyperSQL doesn't connect to any database, but rather works on files. Hence it should work for databases other than Oracle (which it was designed for initially) as well, though I've not tested that. If you do not maintain your database objects that way (but rather develop directly inside the database), some scripts in the tools/ directory of the HyperSQL distribution might help you extract those from your Oracle database. For objects you can COMMENT ON (tables, views) they even create basic JavaDoc comments along. Further details as well as a documentation can be found in the project's wiki.

You can create recursive procedures following the same guidelines. First create the procedure with a simple body that throws an exception. You need to specify the SPECIFIC name of the procedure:

The text.log file is the record of transactions performed on your database. If you disable it with hsqldb.log_data=false the transactions are not persisted to disk. The name is derived from the file name on your database URL.

The hsqldb.sqllog and hsqldb.applog settings are for diagnostics and default to 0.

The hsqldb.reconfig_logging=false is also for diagnostics and works together with hsqldb.applog setting. These settings are discussed in the Guide: http://hsqldb.org/doc/2.0/guide/management-chapt.html#mtc_monitoring_operation

So if you want your data to survive when your app shuts down, you should not disable the default log. See http://hsqldb.org/doc/2.0/guide/management-chapt.html#mtc_cache_persistence on how to reduce the size of the text.log file.

QUESTION

What databases support UNION JOINs?

Asked 2019-May-28 at 16:54

First of all, this item is like a curiosity to me.

I was writing some code for a utility library and was adding methods to run different kinds of SQL join statements. All good, but at some point I came across the obscure UNION JOIN clause included in the SQL-92 spec (page 179).

I don't know how useful it can be (I never used it) and it's implemented (AFAIK) in HyperSQL only.

For the record, here's how it works. If we have two tables T and U with any numbers of colums/rows:

In theory, ANY SQL supports it

As documented in "SQL Problems and Solutions" by Moiseenko:

This join type have been introduced in SQL-92 language standard, but disappeared in later versions of SQL standard. Particularly, it is absent from SQL2003 (ANSI and ISO). As many other structures of SQL, UNION JOIN is excessive because it can be expressed as substraction of full outer join and inner join. Formally, we can write this expression as follows:

QUESTION

Does INTERSECT have a higher precedence compared to UNION?

Asked 2019-May-20 at 17:28

If we consider three single-column tables each having two rows: A = (1, 2), B = (2, 3), C = (3, 4). Then if we try UNION and INTERSECT together using parenthesis, the result is quite consistent:

(select * from a union select * from b) intersect select * from c -> 3
select * from a union (select * from b intersect select * from c) -> 1, 2, 3

But what about plain and simple...

select * from a union select * from b intersect select * from c ?

I've tried it on several databases (SQL Fiddle) and what I empirically got is:

In one corner we have Oracle, PostgreSQL, and H2 that consider INTERSECT having the same precedence as UNION (hence the result is 3).
Then, in the other corner is DB2, SQL Server, MariaDB, Apache Derby, and HyperSQL that consider INTERSECT having a higher precedence than UNION (hence the result is 1, 2, 3).
MySQL and Sybase ASE stay out of the ring, since they don't implement INTERSECT at all.

Do you guys know if there is any official definition on this? I skimmed the SQL-92 spec but couldn't find anything on the subject.

...

ANSWER

Answered 2019-May-20 at 17:25

Oracle has this explanatory note in its documentation:

To comply with emerging SQL standards, a future release of Oracle will give the INTERSECT operator greater precedence than the other set operators. Therefore, you should use parentheses to specify order of evaluation in queries that use the INTERSECT operator with other set operators.

So, Oracle at least thinks that equal precedence is not consistent with the standard.

As a note: I often find the standard so inscrutable that hints like this are simpler than attempting to decipher the actual text.

HSQLDB: REPLACE INTO

Asked 2017-Dec-19 at 02:10

From:

HyperSQL User Guide

HyperSQL Database Engine 2.4.0

Chapter 12. Compatibility With Other DBMS :

HyperSQL supports and translates INSERT IGNORE, REPLACE and ON DUPLICATE KEY UPDATE variations of INSERT into predictable and error-free operations.

When INSERT IGNORE is used, if any of the inserted rows would violate a PRIMARY KEY or UNIQUE constraint, that row is not inserted. The rest of the rows are then inserted only if there is no other violation such as long strings or type mismatch, otherwise the appropriate error is returned.

When REPLACE or ON DUPLICATE KEY UPDATE is used, the rows that need replacing or updating are updated with the given values. This works exactly like an UPDATE statement for those rows. Referential constraints and other integrity checks are enforced and update triggers are activated. The row count returned is simply the total number of rows inserted and updated.

However when I try

ANSWER

Answered 2017-Dec-19 at 02:10

I suggest that you need to enable MySQL compatibility mode in order to get MySQL-specific commands like REPLACE to work. From Chapter 7 of the HSQL documentation:

In MySQL syntax compatibility mode, HyperSQL supports INSERT IGNORE, REPLACE and ON DUPLICATE KEY UPDATE variations of the INSERT statement.

The key point here is that it MySQL syntax compatibility mode needs to be turned on. Following the link to Chapter 12 which you posted in your question we find:

Use SET DATABASE SQL SYNTAX MYS TRUE or the equivalent URL property sql.syntax_mys=true to enable support for AUTO_INCREMENT and TEXT data types and several other types. These type definitions are translated into HyperSQL equivalents.

So the documentation is giving us two ways to enable MySQL compatibility mode. One we can execute directly from the HSQL console:
