About these scripts

These are very rudimentary scripts for importing the LOINC codes into a various databases. These scripts are very basic and should not be used in a production environment. They are provided as a starting point to show one method that can be used to load the LOINC data.

It is highly recommended that you consult with your database administrator before attempting to run these scripts or load these data.

These scripts can be used to import the Loinc.csv, MapTo.csv, and SourceOrganization.csv files into your database. These files are available in our downloadable Loinc_X.XX.zip file within the LoincTable folder.

MySQL

Run the following to make the table structure needed to import the data.

MySqlDdl.sql
DROP TABLE IF EXISTS SourceOrganization;
CREATE TABLE SourceOrganization (
  id  integer default null,
  copyright_id varchar(255) not null,
  name varchar(255) default null,
  copyright text,
  terms_of_use text,
  url text default null,
  primary key (copyright_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS Loinc;
CREATE TABLE Loinc (
  loinc_num varchar(10) not null,
  component varchar(255) default null,
  property varchar(255) default null,
  time_aspct varchar(255) default null,

  VersionFirstReleased varchar(255) default null,
  ValidHL7AttachmentRequest varchar(50) default null,
  DisplayName varchar(255) default null,

  primary key (loinc_num)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

DROP TABLE IF EXISTS MapTo;
CREATE TABLE MapTo (
  loinc varchar(10) NOT NULL,
  map_to varchar(10) NOT NULL,
  comment text,
  primary key (loinc, map_to)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Run the following to perform the import. The script assumes you are using the loinc schema to import the data, if not change the USE statement at the top to use the appropriate schema. Be sure to update the file paths to the correct location of the .csv files before running.

Refer to MySQL’s documentation regarding the LOAD DATA statement. You may need to adjust the server’s security settings or place the files in a privileged location (and omit LOCAL below) in order to the statement to work.

Windows Batch Script

Provided is an basic batch script you can use to automate the execution of the above queries. It is assumed that you are working in a Windows environment and have the MySQL software installed on your PC. Follow these steps to create and run the scripts:

Note: Perform these steps in the directory that contain the .csv files to be imported.

  1. Create a file called MySqlDdl.sql and copy the code under the MySqlDdl.sql filename into that file and save it.
  2. Create a file called MySqlLoader.sql and copy the code under the MySqlLoader.sql filename into that file and save it.
    1. Be sure to update the paths to the .csv files where necessary.
  3. Create a file called LoadMySql.bat and copy the code below into that file and save it.
  4. Update the parameters in the LoadMySql.bat to the values appropriate for your environment.
  5. Run the script using command line or powershell.

Access Database

LOINC is no longer published in a *.mdb (Microsoft Access) format. These instructions show you how to load the available CSV files into Access thereby creating your own Loinc.mdb file. Follow the following steps to import Loinc.csv, MapTo.csv, SourceOrganization.csv into Loinc.mdb.

  1. Create a new Loinc Access database (use the latest version installed in your system)
  2. Delete any auto-created table(s), e.g., “Table1”.
  3. Import Loinc.csv
    • Click on “External Data” from the menu.
    • Click on “New Data Source”, then “From File” then “Text File”.
      • This will open the “Get External Data” dialog box.
    • Click Browse then open Loinc.csv, e.g., [root folder of Loinc_x.xx.zip]\LoincTable\Loinc.csv.
    • In the “Specify how and where you want to store the data…”, click on “Import the source data into a new table in the current database”. Then hit OK.
      • This will open the “Import Text Wizard” dialog box.
    • From the “Import Text Wizard” dialog, choose “Delimited” and accept the default, then click Next.
    • Choose “Comma”, double quote as Text Qualifier, and click on “First Row Contains Field Names”, then hit Next.
    • From the Field Options box, set the Data Type to “Long Text” for the following fields:
      1. Component
      2. DefinitionDescription — should be Long Text by default.
      3. Formula
      4. Exmpl_Answers
      5. Survey_Quest_Text
      6. RelatedNames2
      7. External_Copyright_Notice
      8. LongCommonName
      9. Status_Text
      10. Change_Reason_Public
      11. DisplayName
    • From the primary key screen, click “Choose my own primary key” then choose “LOINC_NUM” from the dropdown.
    • Leave “Loinc” as the “Import to Table” value then hit Finish and click Close in the “Save Import Steps” screen.
  4. Import MapTo.csv
    • Follow the first 6 bullet items from “Import Loinc.csv”, open the MapTo.csv instead.
    • From the Field Options box, set the Data Type to “Long Text” for the following fields:
      1. Comment
    • From the primary key screen, click “No primary key”.
    • Leave “MapTo” as the “Import to Table” value then hit Finish and click Close in the “Save Import Steps” screen.
  5. Import SourceOrganization.csv
    • Follow the first 6 bullet items from “Import Loinc.csv”, open the SourceOrganization.csv instead.
    • From the Field Options box, set the Data Type to “Long Text” for the following fields:
      1. Name
      2. Copyright
      3. TermsOfUse
    • From the primary key screen, click “Choose my own primary key” then choose “ID” from the dropdown.
    • Leave “SourceOrganization” as the “Import to Table” value then hit Finish and click Close in the “Save Import Steps” screen.
  6. Open the imported tables. Take note of the number of rows:
    • Loinc
    • MapTo
    • SourceOrganization
  7. Quick validation
    • There must not be any ImportErrors table.
      • Ensure the fields above are set to LongText to resolve any truncation errors.
    • Open the CSV files (Loinc.csv, MapTo.csv, SourceOrganization.csv) and compare the imported records count versus the number of lines in the CSV.
      • The count must match (excluding the header row in the CSV files)
