Hello,

Column company_id has been removed from all tables. Please try run the following queries after selecting you database

-- allow long concatenated statements
SET SESSION group_concat_max_len = 8192;

-- drop foreign keys that involve company_id
SET @drop_fk := (
  SELECT GROUP_CONCAT(
           CONCAT('ALTER TABLE `', TABLE_SCHEMA, '`.`', TABLE_NAME,
                  '` DROP FOREIGN KEY `', CONSTRAINT_NAME, '`;')
           SEPARATOR ' '
         )
  FROM information_schema.KEY_COLUMN_USAGE
  WHERE COLUMN_NAME = 'company_id'
    AND CONSTRAINT_SCHEMA = DATABASE()
    AND REFERENCED_TABLE_NAME IS NOT NULL
);
SELECT @drop_fk;          -- inspect before running
PREPARE fk_stmt FROM @drop_fk;
EXECUTE fk_stmt;
DEALLOCATE PREPARE fk_stmt;

-- drop secondary indexes that still reference company_id
SET @drop_idx := (
  SELECT GROUP_CONCAT(
           CONCAT('ALTER TABLE `', TABLE_SCHEMA, '`.`', TABLE_NAME,
                  '` DROP INDEX `', INDEX_NAME, '`;')
           SEPARATOR ' '
         )
  FROM information_schema.STATISTICS
  WHERE COLUMN_NAME = 'company_id'
    AND TABLE_SCHEMA = DATABASE()
    AND INDEX_NAME  'PRIMARY'
);
SELECT @drop_idx;
PREPARE idx_stmt FROM @drop_idx;
EXECUTE idx_stmt;
DEALLOCATE PREPARE idx_stmt;

-- drop the company_id column wherever it exists
SET @drop_col := (
  SELECT GROUP_CONCAT(
           CONCAT('ALTER TABLE `', TABLE_SCHEMA, '`.`', TABLE_NAME,
                  '` DROP COLUMN `company_id`;')
           SEPARATOR ' '
         )
  FROM information_schema.COLUMNS
  WHERE COLUMN_NAME = 'company_id'
    AND TABLE_SCHEMA = DATABASE()
);
SELECT @drop_col;
PREPARE col_stmt FROM @drop_col;
EXECUTE col_stmt;
DEALLOCATE PREPARE col_stmt;

-- finally drop the companies table if present
DROP TABLE IF EXISTS `companies`;
