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`,'''') ORDER BY `phenotype_date` ASC ) 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;
