SQLSTATE[42000] Exceptions on reindex

Question

I updated my MAMP site from EE 1.14.1.0 to EE 1.14.2.0. After updating, I also applied the new patch for PHP 7. The site also has all of the required SUPEES. When I try and do a reindexall command inside of terminal, I get the following error an all indexes except for Product Attributes and Tag Aggregation Data:

Catalog Search Index index process unknown error:

In MAMP, I have selected the version of PHP to be 7.2.8.

I have tried to delete the files inside of var/locks.

I have tried applying SUPEE-5984, which was suggested a couple of posts here.

I also tried to truncate the

1. catalog_product_flat_1 and
2. catalog_product_flat_cl tables, which was also suggested.

Use Flat Catalog Category is set to 'No' in my configuration.

Answer 1

It looks like the issue was because I had deleted a database in Sequel Pro and then created a database with the same name.

When I created a new database with a name that hadn't been previously used, I no longer had this issue.
