Missing a matching closing delimiter in statement

With two adjacent single quotes?

dbadmin=> create table data ( name varchar );
CREATE TABLE

dbadmin=> insert into data values ('Dav''id');
 OUTPUT
--------
      1
(1 row)

dbadmin=> select * from data;
  name
--------
 Dav'id
(1 row)

Another option:

dbadmin=> create table data ( name varchar );
CREATE TABLE

dbadmin=> insert into data SELECT $$Dav'id$$;
 OUTPUT
--------
      1
(1 row)

dbadmin=> SELECT * FROM data;
  name
--------
 Dav'id
(1 row)

See:
https://forum.vertica.com/discussion/240097/simplify-string-literals-with-dollar-quoted-string-literals

What do you mean you can't change the format? Of the actual data? The Dollar ($$) quoted method is not changing the data format...

Another example:

dbadmin=> truncate table data;
TRUNCATE TABLE

dbadmin=> \d data
                                   List of Fields by Tables
 Schema | Table | Column |    Type     | Size | Default | Not Null | Primary Key | Foreign Key
--------+-------+--------+-------------+------+---------+----------+-------------+-------------
 public | data  | name   | varchar(80) |   80 |         | f        | f           |
(1 row)

dbadmin=> INSERT INTO data VALUES ($$'Dav'id', 'Smith', Joe, ladouille'$$);
 OUTPUT
--------
      1
(1 row)

dbadmin=> SELECT * FROM data;
                name
------------------------------------
 'Dav'id', 'Smith', Joe, ladouille'
(1 row)

q1 <- paste("COPY DB FROM local '",fichier,"' WITH DELIMITER AS ';' SKIP 1 ABORT ON ERROR",sep="")
res <- dbSendUpdate(vertica1, q1)

Error in .local(conn, statement, ...) :
execute JDBC update query failed in dbSendUpdate ([Vertica]VJDBC ERROR: COPY: Input record 1 has been rejected (Invalid integer format '"Dav'id","XXXXXXX",0,"XXXX","XXXXXXXX","xxxxxx",NA,0,NA,NA,NA' for column 1 (nom_etablissement)))

This is my error

Can you post the structure of the DB table (column names and data types)?

Is the nom_etablissement an integer?

This simple example works fine using the COPY command:

dbadmin=> \! cat /home/dbadmin/yourdata.txt
"Dav'id","XXXXXXX",0,"XXXX","XXXXXXXX","xxxxxx",NA,0,NA,NA,NA

dbadmin=> \d db
