# Title: Change the type of gene_member_qc.seq_member_id to allow a foreign key
#
# Description:
# Foreign keys are only allowed between columns of identical types, but
# gene_member_qc.seq_member_id was not set as "unsigned"

ALTER TABLE gene_member_qc 
      MODIFY COLUMN seq_member_id int(10) unsigned,
      ADD FOREIGN KEY (seq_member_id) REFERENCES seq_member(seq_member_id);

# Patch identifier
INSERT INTO meta (species_id, meta_key, meta_value)
  VALUES (NULL, 'patch', 'patch_90_91_b.sql|gene_member_qc.seq_member_id.unsigned.foreign_key');
