Simple but can cause lots of problems.
I have one column with 200,000 postcode entries! in a CSV file. One Tab. Like below
My first insert of 4000 was quick without error, but the 200,000 had import errors.
I tried many Free CSV splitters online but all had problems except one!
So I cut into 4 CSV files of 50,000 each and this worked (took about 12 seconds).
Now I needed to add to this column with the other imports.
I tried another imports, but now I had four tables.
I changed there names as they had a space in them.
Click on table > operations > change name
So I used SQL
create table tableboth12 like table1;
insert into tableboth12 select * from table1;
insert into tableboth12 select * from table2;
insert into tableboth12 select * from table3;
insert into tableboth12 select * from table4;
(on this last table I forgot to take off the tick on enable foreign key, but it did not make a difference!)
I did notice the row count did not add up correctly, but after a refresh it changed.
innoDB tables count differently!
Now I had this: -
after deleting unused tables : -
Follow this instructio to import CSV:
Go to the Import tab
Browse and select your CSV file
Select "CSV"
Turn off enable foreign
key checks: -
In the “Fields terminated by” field, change “;” to “,”
Click on “Go”
