Question

is there anyway to use cursor in sequelize migration ? i am trying to create DML script ,the idea is to loop the values in table ie. day using cursor and then insert values to other table ie. mealday inside the cursor.

table : day
dayId
dayName

table : meal
mealId
mealName

table : mealday
mealdayId
dayId
mealId

the insert statement i should use inside cursor is :

insert into mealday (dayId,mealId) 
select **dayIdFromCursor**,mealId from meal

Answer 1

as a work around i can simply repeat the insert statement 7 times (number of days in day table) and hard code dayId

insert into mealday (dayId,mealId) 
select 1,mealId from meal

insert into mealday (dayId,mealId) 
select 2,mealId from meal

...

insert into mealday (dayId,mealId) 
select 7,mealId from meal
