Searching for Ethanol-Preserved Parts in OGL:Genomic

We are seeking assistance in searching for ethanol-preserved parts within the OGL:Genomic database. This request falls under the category of a search or data request, as we require help with SQL to retrieve specific fields for our collection.

We are looking to search for all records that have a part for which the preservation is ethanol (any percentage), isopropanol (any percentage), or dry. Our primary goal is to identify records that are stored at room temperature. However, we are unsure if this information is readily available in the database. We have found that one possible way to discern this is by checking if the PLPath is just the container barcode. We would like to search for records that meet this criterion.

Example Use Case

For instance, we would like the record OGL:Genomic:29888 to show up in the search results because it has one ethanol-preserved part that does not have a full PLPath. This record is a prime example of what we are trying to achieve with our search query.

SQL Query Requirements

To accomplish this task, we require assistance with crafting a SQL query that can search for the following conditions:

Preservation method is ethanol (any percentage)
Preservation method is isopropanol (any percentage)
Preservation method is dry
PLPath is just the container barcode (optional)

Database Schema Considerations

When crafting the SQL query, we must consider the database schema and the relationships between the various tables. We need to ensure that the query can effectively retrieve the required information without causing any performance issues.

Potential Solutions

One possible solution is to use a combination of SQL queries to achieve the desired result. We can start by searching for records that have a part with an ethanol, isopropanol, or dry preservation method. Then, we can filter the results to include only records that have a PLPath that is just the container barcode.

Example SQL Query

Here is an example SQL query that meets the requirements:

SELECT *
FROM OGL_Genomic
WHERE EXISTS (
  SELECT 1
  FROM OGL_Genomic_Parts
  WHERE OGL_Genomic_Parts.preservation_method IN ('ethanol', 'isopropanol', 'dry')
  AND OGL_Genomic_Parts.sample_id = OGL_Genomic.id
)
AND EXISTS (
  SELECT 1
  FROM OGL_Genomic_Parts
  WHERE OGL_Genomic_Parts.plpath = OGL_Genomic_Parts.container_barcode
  AND OGL_Genomic_Parts.sample_id = OGL_Genomic.id
);

Conclusion

In conclusion, we require assistance with crafting a SQL query that can search for ethanol-preserved parts in the OGL:Genomic database. We have outlined the requirements and provided an example SQL query to achieve the desired result. We look forward to receiving assistance with this task.
