Executing script file in h2 database

Question

First of all I would like to say am new to h2 database. I need to execute a sql script file in h2 database. I have a script file test.sql and I want to execute this in h2 database. Is it possible?

Answer 1

You can use the RUNSCRIPT SQL statement:

RUNSCRIPT FROM 'test.sql'

or you can use the RunScript standalone / command line tool:

java -cp h2*.jar org.h2.tools.RunScript -url jdbc:h2:~/test -script test.sql

You can also use the RunScript tool within an application:

RunScript.execute(conn, new FileReader("test.sql"));

Answer 2

If you are using spring-boot and spring-test with H2 it will automatically look for schema.sql and data.sql in your class path and attempt to run these. So if you put them in src/test/resources they should be picked up and run automatically

In addition you can specify the data files you want to run with properties. For example adding a property to yourapplication.properties like

spring.datasource.data=classpath:users.sql, classpath:books.sql, classpath:reviews.sql

will configure spring to run those three sql files instead of running data.sql

Answer 3

For me the system responded with:

didn't find org.h2.tools.RunScript driver

The solution was:

java -classpath <path_to_your_h2-*.jar> org.h2.tools.RunScript \
-url jdbc:h2:tcp://localhost/~/test -script test.sql

Answer 4

On OSX (this shouldn't really matter) with v. 1.4.192 with the following commands, no matter what I did I could not see any results:

java -cp h2*.jar org.h2.tools.RunScript -url "jdbc:h2:file:~/testdb" -user someusername -password somepass -script select.sql

where select.sql had simply:

select * from PUBLIC.MYTABLE;

I had to add the -showResults before output began appearing. Here is the complete command:

java -cp /Users/az/.m2/repository/com/h2database/h2/1.4.192/h2-1.4.192.jar org.h2.tools.RunScript -url "jdbc:h2:file:~/testdb" -user someusername -password somepass -script select.sql -showResults

If you do not have the needed jar, download from here (Click on the jar links next to each version). Some direct links to the jars are as follows:

1.4.193 ^{(Updated 31-Oct-2016)}

1.4.192 ^{(Updated 26-May-2016)}

1.4.191 ^{(Updated 21-Jan-2016)}

1.4.190 ^{(Updated 11-Oct-2016)}
