Power Database Fields plugin was not designed for dealing with large amount of data. Sometimes, our users reported issues when more than ~10k records were retrieved by the sql queries. this doesn't mean that the app will not work with more than 10K records, it's just that you might experience issues with performance and data retrieval.
We plan to re-write the plugin at some point in time to overcome this limitation.

Database custom fields don't work on Jira 7.X
After updating to Jira 7, some user experimented this error (Error rendering 'databaseinput') when using SQL Server databases or the custom fields simply don't work when using PostgreSQL databases.

- Download the latest jdbc driver for sql server (at this moment it is sqljdbc4.2)
- Extract the archive and copy the .jar file (sqljdbc42.jar) to lib folder, from your JIRA
Update the resource from context.xml accordingly. It should look like this: | Code Block |
|---|
<Resource name="CONNECTION_NAME"
auth="Container"
type="javax.sql.DataSource"
username="USERNAME"
password="PASSWORD"
driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://SERVER:PORT;DatabaseName=DATABASE_NAME"/> |
Restart Jira.

- Download the latest jdbc driver for Postgres (at this moment it is postgresql-9.4-1204.jdbc4)
Copy the .jar file (postgresql-9.4-1204.jdbc4.jar) to lib folder, from your JIRA Restart Jira.
| Note |
|---|
The same problem may occur for other databasese as well (Oracle, MySQL, hsql). In this case, you should follow the same steps, updating the driver and restarting the JIRA instance. Since version 4.0.0, you may avoid changing the resource in the context.xml file and add the resource directly from the UI, via the "Datasources" page. |

I experience difficulties using special characters
When Power Database Fields users use another language than English and it contains special characters, some translation may happen at the JDBC driver level. To avoid this, ensure that the translation between char codes doesn't happen.

- Go to the conf folder of your Jira and edit the context.xml.

Modify the resource url which defines your data source like this: "useUnicode=yes" and "characterEncoding=UTF-8". | Code Block |

url="jdbc:DRIVER://IP:PORT/DATABASE?useUnicode=yes&characterEncoding=UTF-8" |
Restart your Jira.

How can I use a CF value in the SQL query?
Most of Power Database Fields users are usually using some custom fields in their queries to filter the data returned from database. We're assuming that you have already created a database custom field already at this point.

|
- Go to the Database Custom Field page. You will find the database custom fields here.
- In the SQL query, usually in the WHERE clause, use the custom field id (e.g. customfield_12345) or the standard fields between braces. You can find the list of standard fields and more details about dynamic query on the Dynamic Query (SQL) page.
| Info |

Note that this only works for single value Custom Fields. If you need to use multiple value CF, there is a recipe for it here: Using DBCF queries: IN clauses |
