I have the below code.
BEGIN
NULL;
END;
DROP TABLE TEST_1;
CREATE TABLE TEST_1 AS
select 1 h from dual;
However, when executing as a script (F5) in SQL Developer, the below error is thrown. What is the way around this?
ORA-06550: línea 4, columna 1:
PLS-00103: Encountered the symbol "DROP"
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.

I am trying to upload a CSV file using the following syntax
LOAD DATA LOCAL INFILE 'C:\\Users\\file\\upload.csv' INTO TABLE customer
FIELDS TERMINATED BY ';'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS
(#col1,#col2,#col3) SET
account_number=#col1,
customer=#col2,
customer_id=#col3
;
It works without the IGNORE 1 ROWS line.
Which is the right syntax to include IGNORE 1 ROWS in this case?
It looks like you are using MariaDB and not MySQL. The syntax IGNORE 1 ROWS is only supported by MySQL.
The syntax supported by both MySQL and MariaDB is IGNORE 1 LINES

I have loaded a csv file into r called my_data. But some columns have multiple fields and I want to split them into separate new columns. When executing this command:
separate(data=my_data,col=totals,into=c("Visits" , "Hits", "Pageviews",
"TransactionRevenue", "NewVisits"),sep=”,”)
I get this error message:
Error: unexpected symbol in "separate(data=my_data,col=totals,into=c("Visits" , "Hits", "Pageviews", "TransactionRevenue”, "NewVisits"
I am trying to figure out what is wrong but with no success. Any help?
It looks like the sep= has smart quotes instead of straight quotes. Try changing it to
separate(data=my_data,col=totals,into=c("Visits" , "Hits", "Pageviews",
"TransactionRevenue", "NewVisits"),sep=",")

df = read.csv(("/home/rstudio/IMDB_data.csv" ,header=T ,fileEncoding='latin1', sep=",")[-2,])
I wrote the above R code to remove the second line in a file, however it is not working.
This process was already shown in a previous example here, But it's giving me error message unexpected : ','
This should work.
df = read.csv("/home/rstudio/IMDB_data.csv" ,header=T ,fileEncoding='latin1', sep=",")[-2,]

I trying to use following piece code in R Studio and I'm expecting a result that calculates b for 1:3 times.
for(b in 1:3){+cat(b,"+",b,"=",b+b, "\n")+}
However I keep getting an error:
Error: unexpected '}' in: "cat(b,"+",b,"=",b+b, "\n")+}"
Can anyone help please?
It expects something to add, but there is nothing to the right hand side of +.

I have searched for answers to my question and can't seem to find any answer. I am trying to sort my data so that I can first sort by year of birth and then by last name. Here is my code:
ResidentsBD_99_2015_clean < ResidentsBD_99_2015_clean[order(ResidentsBD_99_2015_clean[, birthdate_year],
ResidentsBD_99_2015_clean[, "surname"],
decreasing = FALSE), ]
When I run this code, this is the error message that I recieve:
Error in `[.data.frame`(ResidentsBD_99_2015_clean, , birthdate_year) :
undefined columns selected
You might just be stuck with typos in your code. birthdate_year should be quoted. It also looks like you have a typo in the assign-operator (<-).
In a more general sense, I prefer ordering with dplyr.
library(dplyr)
ResidentsBD_99_2015_clean <- arrange(ResidentsBD_99_2015_clean, birthdate_year, surname)
From what I can see from your code, it might just be the missing - in the assignment and some small syntax problem. Try this:
ResidentsBD_99_2015_clean<- ResidentsBD_99_2015_clean[order(ResidentsBD_99_2015_clean$birthdate_year, ResidentsBD_99_2015_clean$surname),]
