Magento 2 Product EAV Index Failing After Downgrading

Published: January 18, 2018


Recently one of my co-workers reported experiencing the following error when running a product eav reindex.

SQLSTATE[21S01]: Insert value list does not match column list: 1136 Column count doesn't match value count at row 1, query was: INSERT INTO `catalog_product_index_eav_idx` SELECT DISTINCT  `pid`.`entity_id`, `pid`.`attribute_id`, `pid`.`store_id`, IFNULL(pis.value, pid.value) AS `value` FROM (SELECT DISTINCT  `s`.`store_id`, `s`.`website_id`, `dd`.`attribute_id`, COALESCE(ds.value, dd.value) AS `value`, `cpe`.`row_id`, `cpe`.`entity_id` FROM `store` AS `s`
 LEFT JOIN `catalog_product_entity_int` AS `dd` ON dd.store_id = 0
 LEFT JOIN `catalog_product_entity_int` AS `ds` ON ds.store_id = s.store_id AND ds.attribute_id = dd.attribute_id AND ds.row_id = dd.row_id
 LEFT JOIN `catalog_product_entity_int` AS `d2d` ON d2d.store_id = 0 AND d2d.row_id = dd.row_id AND d2d.attribute_id = 292
 LEFT JOIN `catalog_product_entity_int` AS `d2s` ON d2s.store_id = s.store_id AND d2s.attribute_id = d2d.attribute_id AND d2s.row_id = d2d.row_id
 LEFT JOIN `catalog_product_entity` AS `cpe` ON cpe.row_id = dd.row_id AND (cpe.created_in <= '1509969103' AND cpe.updated_in > '1509969103') WHERE (s.store_id != 0) AND ((ds.value IS NOT NULL OR dd.value IS NOT NULL)) AND (COALESCE(d2s.value, d2d.value) = 1)) AS `pid`
 LEFT JOIN `catalog_product_entity_int` AS `pis` ON pis.row_id = pid.row_id AND pis.attribute_id = pid.attribute_id AND pis.store_id = pid.store_id WHERE (pid.attribute_id IN('802')) AND (IFNULL(pis.value, pid.value) IS NOT NULL) AND (NOT(pis.value IS NULL AND pis.value_id IS NOT NULL))

The error indicates that catalog_product_index_eav_idx does not match the column list being INSERT-ed…

IFNULL(pis.value, pid.value) AS `value`

I asked my co-worker to check and indeed, catalog_product_index_eav_idx contained an additional column (source_id).

With some crafty googling I was able to track down an article titled “Magento2 Upgrdation from 2.2.0 dev to 2.1.6 upgrade eav attribute indexing problem” (sic) which states the following…

  1. Its come due to source_id column exist in 2.2.0 Dev version but it not exist in latest magento 2.1.6 version

  2. So we have to remove source_id column from some tables names as :

    • catalog_product_index_eav
    • catalog_product_index_eav_decimal
    • catalog_product_index_eav_decimal_idx
    • catalog_product_index_eav_idx

I asked my co-worker if he had recently downgraded his environment and in fact, he had recently gone from 2.1.10 back to 2.1.3.

Upon further research I found the following code in Magento\Catalog\Setup\UpgradeSchema

// Magento\Catalog\Setup\UpgradeSchema
if (version_compare($context->getVersion(), '2.1.4', '<')) {

Here’s an abbreviated version of addSourceEntityIdToProductEavIndex()

$tables = [

foreach ($tables as $tableName) {
    $tableName = $setup->getTable($tableName);
            'type' => \Magento\Framework\DB\Ddl\Table::TYPE_INTEGER,
            'unsigned' => true,
            'nullable' => false,
            'default' => 0,
            'comment' => 'Original entity Id for attribute value',

As you can see, it does add the source_id column to a number of tables.

It’s a bit odd that the article I found stated that source_id was not present in 2.1.6, however the code indicates it is available starting from 2.1.4. Regardless, deleting source_id from the tables in question did fix the issue and allowed him to reindex product eav.
