It has been reported that when using Install4j on some Linux systems and enabling the 'pack200' option, the h2.jar becomes corrupted by the install process, causing application failure. A workaround is to add an empty file h2.jar.nopack next to the h2.jar file. The reason for this problem is not known.

Triggers are no longer executed when changing the table structure (ALTER TABLE).
@changelog_1090_li
@changelog_1092_li
When setting BLOB or CLOB values larger than 65 KB using a remote connection, temporary files were kept on the client longer than required (until the connection was closed or the object is garbage collected).

@changelog_1102_h2
Version 1.0.70 (2008-04-20)
@changelog_1101_li
@changelog_1103_li
The plan is to dual-license H2. The additional license is EPL (Eclipse Public License). The current license (MPL, Mozilla Public License) will stay. Current users are not affected because they can keep MPL. EPL is very similar to MPL, the only bigger difference is related to patents (EPL is a bit more business friendly in this regard). See also http://opensource.org/licenses/eclipse-1.0.php, http://www.eclipse.org/legal/eplfaq.php (FAQ), http://blogs.zdnet.com/Burnette/?p=131

The code switch tool has been replaced by a simpler tool called SwitchSource that just uses find and replace.
@changelog_1110_li
@changelog_1112_li
Started to write a Ant replacement ('JAnt') that uses pure Java build definitions. Advantages: ability to debug the build, extensible, flexible, no XML, a bit faster. Future plan: support creating custom h2 distributions (for embedded use). Maybe create a new project 'Jant' or 'Javen' if other people are interested.
@changelog_1111_li
@changelog_1113_li
The jar file is now about 10% smaller because the variable debugging info is no longer included. The source file and line number debugging info is still included. If required, the jar file size of the full version can be further reduced to about 720 KB using 'build jarSmall' or even more by removing unneeded components.
@changelog_1112_li
@changelog_1114_li
Added shell scripts run.sh and build.sh. chmod +x is required, but otherwise it should work. Feedback or improvements are welcome!
@changelog_1113_li

Optimization for MIN() and MAX() when using MVCC.
@changelog_1117_li
@changelog_1119_li
To protect against remote brute force password attacks, the delay after each unsuccessful login now gets double as long. New system properties h2.delayWrongPasswordMin and h2.delayWrongPasswordMax.
@changelog_1118_li
@changelog_1120_li
After setting the query timeout and then resetting it, the next query would still timeout. Fixed.
@changelog_1119_li
@changelog_1121_li
Adding a IDENTITY column to a table with data threw a lock timeout.
@changelog_1120_li
@changelog_1122_li
OutOfMemoryError could occur when using EXISTS or IN(SELECT ..).

Most command line tools can now be called from within the H2 Console.
@changelog_1126_li
@changelog_1128_li
A new Shell tools is now included (org.h2.tools.Shell) to query a database from the command line.
@changelog_1127_li
@changelog_1129_li
The command line options in the tools have changed: instead of '-log true' now '-trace' is used. Also, '-ifExists', '-tcpSSL' and '-tcpAllowOthers' and so on have changed: now the 'true' is no longer needed. The old behavior is still supported.
@changelog_1128_li
@changelog_1130_li
New system property h2.sortNullsHigh to invert the default sorting behavior for NULL. The default didn't change.
@changelog_1129_li
@changelog_1131_li
Performance was very slow when using LOG=2 and deleting or updating all rows of a table in a loop. Fixed.
@changelog_1130_li
@changelog_1132_li
ALTER TABLE or CREATE TABLE now support parameters for the password field.
@changelog_1131_li
@changelog_1133_li
The linear hash has been removed. It was always slower than the b-tree index, and there were some bugs that would be hard to fix.
@changelog_1132_li
@changelog_1134_li
TRACE_LEVEL_ settings are no longer persistent. This was a problem when database initialization code caused a lot of trace output.
@changelog_1133_li
@changelog_1135_li
Fulltext search (native implementation): The words table is no longer an in-memory table because this caused memory problems in some cases.
@changelog_1134_li
@changelog_1136_li
It was possible to create a role with the name as an existing user (but not vice versa). This is not allowed any more.
@changelog_1135_li
@changelog_1137_li
The recovery tool didn't work correctly for tables without rows.
@changelog_1136_li
@changelog_1138_li
For years below 1, the YEAR method didn't return the correct value, and the conversion from date and timestamp to varchar was incorrect.
@changelog_1137_li
@changelog_1139_li
CSVWRITE caused a NullPointerException when not specifying a nullString.
@changelog_1138_li
@changelog_1140_li
When a log file switch occurred just after a truncate table or drop table statement, the database could not be started normally (RECOVER=1 was required). Fixed.
@changelog_1139_li
@changelog_1141_li
When a log file switch occurred in the middle of a sequence flush (sequences are only flushed every 32 values by default), the sequence value was lost. Fixed.
@changelog_1140_li
@changelog_1142_li
Altering a sequence didn't unlock the system table when autocommit switched off.
@changelog_1141_h2
@changelog_1143_h2
Version 1.0.68 (2008-03-18)
@changelog_1142_li
@changelog_1144_li
Very large SELECT DISTINCT and UNION EXCEPT queries are now supported, however this feature is disabled by default. To enable it, set the system property h2.maxMemoryRowsDistinct to a lower value, for example 10000.

It is also possible to use the SQL command SCRIPT to create the backup of the database. For more information about the options, see the SQL command SCRIPT. The backup can be done remotely, however the file will be created on the server side. The built in FTP server could be used to retrieve the file from the server.

Restore from a Script
@tutorial_1118_p
@tutorial_1119_p
To restore a database from a SQL script file, you can use the RunScript tool:
@tutorial_1119_p
@tutorial_1120_p
For more information about the options, see the SQL command RUNSCRIPT. The restore can be done remotely, however the file needs to be on the server side. The built in FTP server could be used to copy the file to the server. It is also possible to use the SQL command RUNSCRIPT to execute a SQL script. SQL script files may contain references to other script files, in the form of RUNSCRIPT commands. However, when using the server mode, the references script files need to be available on the server side.
@tutorial_1120_h3
@tutorial_1121_h3
Online Backup
@tutorial_1121_p
@tutorial_1122_p
The BACKUP SQL statement and the Backup tool both create a zip file with all database files. However, the contents of this file are not human readable. Other than the SCRIPT statement, the BACKUP statement does not lock the database objects, and therefore does not block other users. The resulting backup is transactionally consistent:
@tutorial_1122_p
@tutorial_1123_p
The Backup tool (org.h2.tools.Backup) can not be used to create a online backup; the database must not be in use while running this program.

Using OpenOffice Base
@tutorial_1152_p
@tutorial_1153_p
OpenOffice.org Base supports database access over the JDBC API. To connect to a H2 database using OpenOffice Base, you first need to add the JDBC driver to OpenOffice. The steps to connect to a H2 database are:
@tutorial_1153_li
@tutorial_1154_li
Start OpenOffice Writer, go to [Tools], [Options]
@tutorial_1154_li
@tutorial_1155_li
Make sure you have selected a Java runtime environment in OpenOffice.org / Java
@tutorial_1155_li
@tutorial_1156_li
Click [Class Path...], [Add Archive...]
@tutorial_1156_li
@tutorial_1157_li
Select your h2.jar (location is up to you, could be wherever you choose)
@tutorial_1157_li
@tutorial_1158_li
Click [OK] (as much as needed), stop OpenOffice (including the Quickstarter)
@tutorial_1158_li
@tutorial_1159_li
Start OpenOffice Base
@tutorial_1159_li
@tutorial_1160_li
Connect to an existing database; select JDBC; [Next]
@tutorial_1160_li
@tutorial_1161_li
Example datasource URL: jdbc:h2:~/test
@tutorial_1161_li
@tutorial_1162_li
JDBC driver class: org.h2.Driver
@tutorial_1162_p
@tutorial_1163_p
Now you can access the database stored in the current users home directory.
@tutorial_1163_p
@tutorial_1164_p
To use H2 in NeoOffice (OpenOffice without X11):
@tutorial_1164_li
@tutorial_1165_li
In NeoOffice, go to [NeoOffice], [Preferences]
@tutorial_1165_li
@tutorial_1166_li
Look for the page under [NeoOffice], [Java]
@tutorial_1166_li
@tutorial_1167_li
Click [Classpath], [Add Archive...]
@tutorial_1167_li
@tutorial_1168_li
Select your h2.jar (location is up to you, could be wherever you choose)
@tutorial_1168_li
@tutorial_1169_li
Click [OK] (as much as needed), restart NeoOffice.
@tutorial_1169_p
@tutorial_1170_p
Now, when creating a new database using the "Database Wizard":
@tutorial_1170_li
@tutorial_1171_li
Select "connect to existing database" and the type "jdbc". Click next.
@tutorial_1171_li
@tutorial_1172_li
Enter your h2 database URL. The normal behavior of H2 is that a new db is created if it doesn't exist.
@tutorial_1172_li
@tutorial_1173_li
Next step - up to you... you can just click finish and start working.
@tutorial_1173_p
@tutorial_1174_p
Another solution to use H2 in NeoOffice is:
@tutorial_1174_li
@tutorial_1175_li
Package the h2 jar within an extension package
@tutorial_1175_li
@tutorial_1176_li
Install it as a Java extension in NeoOffice
@tutorial_1176_p
@tutorial_1177_p
This can be done by create it using the NetBeans OpenOffice plugin. See also <a href="http://wiki.services.openoffice.org/wiki/Extensions_development_java">Extensions Development</a> .
@tutorial_1177_h2
@tutorial_1178_h2
Java Web Start / JNLP
@tutorial_1178_p
@tutorial_1179_p
When using Java Web Start / JNLP (Java Network Launch Protocol), permissions tags must be set in the .jnlp file, and the application .jar file must be signed. Otherwise, when trying to write to the file system, the following exception will occur: java.security.AccessControlException: access denied (java.io.FilePermission ... read). Example permission tags:
@tutorial_1179_h2
@tutorial_1180_h2
Using a Connection Pool
@tutorial_1180_p
@tutorial_1181_p
For many databases, opening a connection is slow, and it is a good idea to use a connection pool to re-use connections. For H2 however opening a connection usually is fast if the database is already open. Using a connection pool for H2 actually slows down the process a bit, except if file encryption is used (in this case opening a connection is about half as fast as using a connection pool). A simple connection pool is included in H2. It is based on the <a href="http://www.source-code.biz/snippets/java/8.htm">Mini Connection Pool Manager</a> from Christian d'Heureuse. There are other, more complex connection pools available, for example <a href="http://jakarta.apache.org/commons/dbcp/">DBCP</a> . The build-in connection pool is used as follows:
@tutorial_1181_h2
@tutorial_1182_h2
Fulltext Search
@tutorial_1182_p
@tutorial_1183_p
H2 supports Lucene full text search and native full text search implementation.
@tutorial_1183_h3
@tutorial_1184_h3
Using the Native Full Text Search
@tutorial_1184_p
@tutorial_1185_p
To initialize, call:
@tutorial_1185_p
@tutorial_1186_p
You need to initialize it in each database where you want to use it. Afterwards, you can create a full text index for a table using:
@tutorial_1186_p
@tutorial_1187_p
PUBLIC is the schema, TEST is the table name. The list of column names (column separated) is optional, in this case all columns are indexed. The index is updated in read time. To search the index, use the following query:
@tutorial_1187_p
@tutorial_1188_p
You can also call the index from within a Java application:
@tutorial_1188_h3
@tutorial_1189_h3
Using the Lucene Fulltext Search
@tutorial_1189_p
@tutorial_1190_p
To use the Lucene full text search, you need the Lucene library in the classpath. How his is done depends on the application; if you use the H2 Console, you can add the Lucene jar file to the environment variables H2DRIVERS or CLASSPATH. To initialize the Lucene full text search in a database, call:
@tutorial_1190_p
@tutorial_1191_p
You need to initialize it in each database where you want to use it. Afterwards, you can create a full text index for a table using:
@tutorial_1191_p
@tutorial_1192_p
PUBLIC is the schema, TEST is the table name. The list of column names (column separated) is optional, in this case all columns are indexed. The index is updated in read time. To search the index, use the following query:
@tutorial_1192_p
@tutorial_1193_p
You can also call the index from within a Java application:
@tutorial_1193_h2
@tutorial_1194_h2
User-Defined Variables
@tutorial_1194_p
@tutorial_1195_p
This database supports user-defined variables. Variables start with @ and can be used wherever expressions or parameters are used. Variables not persisted and session scoped, that means only visible for the session where they are defined. A value is usually assigned using the SET command:
@tutorial_1195_p
@tutorial_1196_p
It is also possible to change a value using the SET() method. This is useful in queries:
@tutorial_1196_p
@tutorial_1197_p
Variables that are not set evaluate to NULL. The data type of a user-defined variable is the data type of the value assigned to it, that means it is not necessary (or possible) to declare variable names before using them. There are no restrictions on the assigned values; large objects (LOBs) are supported as well.
@tutorial_1197_h2
@tutorial_1198_h2
Date and Time
@tutorial_1198_p
@tutorial_1199_p
Date, time and timestamp values support ISO 8601 formatting, including time zone:
@tutorial_1199_p
@tutorial_1200_p
If the time zone is not set, the value is parsed using the current time zone setting of the system. Date and time information is stored in H2 database files in GMT (Greenwich Mean Time). If the database is opened using another system time zone, the date and time will change accordingly. If you want to move a database from one time zone to the other and don't want this to happen, you need to create a SQL script file using the SCRIPT command or Script tool, and then load the database using the RUNSCRIPT command or the RunScript tool in the new time zone.

OpenOffice Baseを使用する
@tutorial_1152_p
@tutorial_1153_p
OpenOffice.org Base はJDBC API上のデータベースアクセスをサポートしています。 OpenOffice Baseを使ってH2データベースに接続するためには、最初にOpenOfficeにJDBCドライバを追加する必要があります。H2データベースに接続する手順:
@tutorial_1153_li
@tutorial_1154_li
#Start OpenOffice Writer, go to [Tools], [Options]
@tutorial_1154_li
@tutorial_1155_li
#Make sure you have selected a Java runtime environment in OpenOffice.org / Java
@tutorial_1155_li
@tutorial_1156_li
#Click [Class Path...], [Add Archive...]
@tutorial_1156_li
@tutorial_1157_li
#Select your h2.jar (location is up to you, could be wherever you choose)
@tutorial_1157_li
@tutorial_1158_li
#Click [OK] (as much as needed), stop OpenOffice (including the Quickstarter)
@tutorial_1158_li
@tutorial_1159_li
OpenOffice Base を起動する
@tutorial_1159_li
@tutorial_1160_li
存在するデータベースに接続し、JDBCを選択し、[Next] をクリックする
@tutorial_1160_li
@tutorial_1161_li
#Example datasource URL: jdbc:h2:~/test
@tutorial_1161_li
@tutorial_1162_li
JDBCドライバクラス: org.h2.Driver
@tutorial_1162_p
@tutorial_1163_p
#Now you can access the database stored in the current users home directory.
@tutorial_1163_p
@tutorial_1164_p
#To use H2 in NeoOffice (OpenOffice without X11):
@tutorial_1164_li
@tutorial_1165_li
#In NeoOffice, go to [NeoOffice], [Preferences]
@tutorial_1165_li
@tutorial_1166_li
#Look for the page under [NeoOffice], [Java]
@tutorial_1166_li
@tutorial_1167_li
#Click [Classpath], [Add Archive...]
@tutorial_1167_li
@tutorial_1168_li
#Select your h2.jar (location is up to you, could be wherever you choose)
@tutorial_1168_li
@tutorial_1169_li
#Click [OK] (as much as needed), restart NeoOffice.
@tutorial_1169_p
@tutorial_1170_p
#Now, when creating a new database using the "Database Wizard":
@tutorial_1170_li
@tutorial_1171_li
#Select "connect to existing database" and the type "jdbc". Click next.
@tutorial_1171_li
@tutorial_1172_li
#Enter your h2 database URL. The normal behavior of H2 is that a new db is created if it doesn't exist.
@tutorial_1172_li
@tutorial_1173_li
#Next step - up to you... you can just click finish and start working.
@tutorial_1173_p
@tutorial_1174_p
#Another solution to use H2 in NeoOffice is:
@tutorial_1174_li
@tutorial_1175_li
#Package the h2 jar within an extension package
@tutorial_1175_li
@tutorial_1176_li
#Install it as a Java extension in NeoOffice
@tutorial_1176_p
@tutorial_1177_p
#This can be done by create it using the NetBeans OpenOffice plugin. See also <a href="http://wiki.services.openoffice.org/wiki/Extensions_development_java">Extensions Development</a> .

#Using a Connection Pool
@tutorial_1180_p
@tutorial_1181_p
#For many databases, opening a connection is slow, and it is a good idea to use a connection pool to re-use connections. For H2 however opening a connection usually is fast if the database is already open. Using a connection pool for H2 actually slows down the process a bit, except if file encryption is used (in this case opening a connection is about half as fast as using a connection pool). A simple connection pool is included in H2. It is based on the <a href="http://www.source-code.biz/snippets/java/8.htm">Mini Connection Pool Manager</a> from Christian d'Heureuse. There are other, more complex connection pools available, for example <a href="http://jakarta.apache.org/commons/dbcp/">DBCP</a> . The build-in connection pool is used as follows:

#User-Defined Variables
@tutorial_1194_p
@tutorial_1195_p
#This database supports user-defined variables. Variables start with @ and can be used wherever expressions or parameters are used. Variables not persisted and session scoped, that means only visible for the session where they are defined. A value is usually assigned using the SET command:
@tutorial_1195_p
@tutorial_1196_p
#It is also possible to change a value using the SET() method. This is useful in queries:
@tutorial_1196_p
@tutorial_1197_p
#Variables that are not set evaluate to NULL. The data type of a user-defined variable is the data type of the value assigned to it, that means it is not necessary (or possible) to declare variable names before using them. There are no restrictions on the assigned values; large objects (LOBs) are supported as well.
@tutorial_1197_h2
@tutorial_1198_h2
#Date and Time
@tutorial_1198_p
@tutorial_1199_p
#Date, time and timestamp values support ISO 8601 formatting, including time zone:
@tutorial_1199_p
@tutorial_1200_p
#If the time zone is not set, the value is parsed using the current time zone setting of the system. Date and time information is stored in H2 database files in GMT (Greenwich Mean Time). If the database is opened using another system time zone, the date and time will change accordingly. If you want to move a database from one time zone to the other and don't want this to happen, you need to create a SQL script file using the SCRIPT command or Script tool, and then load the database using the RUNSCRIPT command or the RunScript tool in the new time zone.
