The manual phenotyping database contains phenotypic field data that was collected by hand.

The main tables in the manual phenotyping database are shown in the figure below.

Example Queries

Row-to-Column Query

FOR QUERY OF REPEATED MEASUREMENTS: This query can be used to extract a column format of a repeat measurements (over dates) for a single trait.

The query below is an example of how to generate a report of the PCTHEAD (percent heading) trait from the 16ASH plots.

SET SESSION group_concat_max_len = 10000;
SET @SQL = NULL;
SELECT
  GROUP_CONCAT(DISTINCT
    CONCAT(
      'MAX(IF(phenotype_date = ''', `phenotype_date`, ''',phenotype_value,NULL)) AS ''', `phenotype_date`,'''')
  ) INTO @SQL FROM phenotype WHERE YEAR(phenotype_date) = 2016;
SET @SQL = CONCAT('SELECT  entity_id, ', @SQL, ' 
                  FROM    phenotype WHERE phenotype.entity_id LIKE ''%16ASH0%'' AND phenotype.trait_id LIKE ''%PCTHEAD%''
                  GROUP   BY entity_id');
PREPARE stmt FROM @SQL;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
