How to split bigint from a comma seperated string

'700000013,700000039,700000047'

I need to split numbers from above string and need to put them in to a table column like;

• ids
• 700000013
• 700000039
• 700000047

length of the string can be variable (can be add more ids in defferent times. I can use a procedure for this.

I need the easiest way like using STRING_SPLIT ( string , separator ) . but this not working on heidiSQL.

How can I solve this?
