Hello Magento Friends,
In this blog, I am going to provide a solution to Fix Invalid Column Data Type when Reindex Magento 2.
Reindexing is required when the store data changes to increase the performance of the Magento 2 storefront. You can perform reindex through the command line or reindex programmatically in Magento 2.
But sometimes the reindex command throws an error of invalid column data type as shown in the below image
Let’s see How to Fix Invalid Column Data Type when Reindex Magento 2
Steps to Fix Invalid Column Data Type when Reindex Magento 2:
Step 1: Go to the below path
vendor/magento/module-eav/Model/ResourceModel/Helper.php
Insert the following lines into getDdlTypeByColumnType() function
|
1 2 3 4 5 6 7 8 9 |
case 'int unsigned': $columnType = 'int'; break; case 'smallint unsigned': $columnType = 'smallint'; break; case 'bigint unsigned': $columnType = 'bigint'; break; |
So the getDdlTypeByColumnType() function before looked like this
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
public function getDdlTypeByColumnType($columnType) { switch ($columnType) { case 'char': case 'varchar': $columnType = 'text'; break; case 'tinyint': $columnType = 'smallint'; break; default: break; } return array_search($columnType, $this->_ddlColumnTypes); } |
And now the getDdlTypeByColumnType() function has changed as below
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
public function getDdlTypeByColumnType($columnType) { switch ($columnType) { case 'int unsigned': $columnType = 'int'; break; case 'smallint unsigned': $columnType = 'smallint'; break; case 'bigint unsigned': $columnType = 'bigint'; break; case 'char': case 'varchar': $columnType = 'text'; break; case 'tinyint': $columnType = 'smallint'; break; default: break; } return array_search($columnType, $this->_ddlColumnTypes); } |
Conclusion:
Hence, this way you can get rid of Invalid Column Data Type while Reindexing in Magento 2. Additionally, if you face an error like “index is locked by another reindex process. Skipping.” while reindexing in Magento 2, you can easily solve it – Check the steps
