Subject [jira] Commented: (JCR-1366) DbDataStore: tablePrefix not accomodated during init test for existing DATASTORE table
Date Mon, 11 Feb 2008 19:13:07 GMT

    [ https://issues.apache.org/jira/browse/JCR-1366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12567760#action_12567760
] 

Tyson Norris commented on JCR-1366:
-----------------------------------

We would like to be able to change the table name so that its use is obvious - i.e. change
"DATASTORE" to "JACKRABBIT_DATASTORE". It is unlikely that we would have a collision with
the name DATASTORE, but nevertheless, it is possible. All other config options have proper
working prefix options so that all of our JACKRABBIT tables are effectively named with the
prefix "JACKRABBIT_".

Thanks!
Tyson

> we are providing a test db deployment with prepopulated data, including jackrabbit DataStore.
I tried specifying the tablePrefix when creating the initial repository, and tables are created
properly.
> However, when a clean installation is run with a fresh database that has an existing
DataStore (stored at JACKRABBIT_DS_DATASTORE table), the startup fails, because during init,
the meta data only checks for tables name matching the tableSQL property:
> ResultSet rs = meta.getTables(null, null, tableSQL, null);
> but the tableSQL property is never modified based on the tablePrefix property (other
uses of tableSQL modify queries based on the prefix).
> I think the init method should modify the tested table name based on the tablePrefix.
> Note: I assume different JDBC drivers may handle this differently (we are using SQL Server
2007 and jTDS driver), since the DatabaseMetaData is API is unclear on the parameter to getTables
being a "tableNamePattern" - should wildcards work? Or should a specific table be specified?

> My DataStore config is below:
>     <DataStore class="org.apache.jackrabbit.core.data.db.DbDataStore">
>       <param name="className" value="org.apache.jackrabbit.core.data.db.DbDataStore"/>
>       <param name="url" value="jdbc:jtds:SQLServer://localhost:1433/nga_admin;prepareSQL=2;responseBuffering=adaptive"/>
>       <param name="user" value="sa"/>
>       <param name="password" value=""/>
>       <param name="databaseType" value="sqlserver"/>
>       <param name="driver" value="net.sourceforge.jtds.jdbc.Driver"/>
>       <!-- a bug in jackrabbit makes tablePrefix not work -->
>       <param name="tablePrefix" value="JACKRABBIT_DS_">
>       <param name="minRecordLength" value="1"/>
>       <param name="maxConnections" value="2"/>
>       <param name="copyWhenReading" value="true"/>         
>     </DataStore>
