delimiter

问题 I have a ton of files which are delimited by |, however, they have | as values in the fields as well. the | in the data has been escaped with \ but I don't think BQ is picking it up, is this something I can fix without having to open every single file, and updating? there are 2-3000 files and are all zipped, so doing it one by one is not at all practical. 回答1: Read each row as a whole line (CSV, with a weird character delimiter). Parse in BigQuery - either via REGEX or JavaScript UDF. I

问题 Ok so, I've been ripping my hairs ou on this one, why doesn't this work? DELIMITER | CREATE PROCEDURE Decrypt_pw() READS SQL DATA BEGIN SELECT 'Hey Select'; END| It's so basic and I'm pretty sure I'm using the correct syntax, what am I missing? Error: 21:14:07 [DELIMITER - 0 row(s), 0.000 secs] [Error Code: 1064, SQL State: 42000] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER | CREATE PROCEDURE

问题 I am creating a tex file in Matlab. The end goal is to create a pdf using latex. I have using following website to check the latex I have is correct latex generator. Everything is fine about from when I have a number that contains comma's for example 5,236,012. The issue comes when I copy the data from the tex file. The column delimiter is set to Commas, how can I change this to Semicolon? 回答1: Use strrep - %%// input_filepath and output_filepath are the filepaths of the %%// input and output

问题 I have a data like below: A:B:C:D and I want to replace the C with data (say, Z ) so that it may look like A:B:Z:D How can I do it? 回答1: =SUBSTITUTE(A1,"C","Z") Although I wasn't clear on whether you wanted G or Z , you mentioned G but your example output shows Z . 回答2: If you have A:B:C:D in cell A1, then this works: =CONCATENATE(MID(A1, 1, SEARCH(":", MID(A1, SEARCH(":", A1) + 1, LEN(A1) - SEARCH(":", A1) + 1)) + SEARCH(":", A1)), "Z", MID(MID(MID(A1, SEARCH(":", A1) + 1, LEN(A1) - SEARCH("

问题 I'm using strtok to split a string into tokens. Does anyone know any function which actually counts the number of tokens? I have a command string and I need to split it and pass the arguments to execve() . Thanks! Edit execve takes arguments as char** , so I need to allocate an array of pointers. I don't know how many to allocate without knowing how many tokens are there. 回答1: One approach would be to simply use strtok with a counter. However, that will modify the original string. Another

问题 Running this procedure causes MySQL (or phpMyAdmin) to freeze. I have to stop MySQL with from XAMPP command, which freezes and "is not responding" about 20 seconds before stopping. I believe this is caused by the delimiter command, which on it's own begins the problems. I have tried using a different delimiter ("//") to no effect. DELIMITER $ CREATE TRIGGER coroner AFTER INSERT ON events FOR EACH ROW BEGIN UPDATE teams WHERE id = NEW.victim SET live = live-1; UPDATE teams WHERE id = NEW

问题 How can I convert user number input from something like 11,5 to 11.5? I have tried the following as callback: before_validation :comma_to_delimiter def comma_to_delimiter self.price.to_s.gsub(',', '.').to_f end But this doesn't work. I want the user to be able to type in whatever he wants as delimiter - currently, the app throws an error when the user uses a comma instead of a point. 回答1: What you're doing may not be the best way, so perhaps someone can answer with a better approach. But to

问题 I feel like I'm going around in circles with FOR loop options. I'm trying to take a string (output of a command) and split it on commas, then use each value to SET, e.g. String: USER=Andy,IP=1.2.3.4,HOSTNAME=foobar,PORT=1234 So I want to split on comma and then literally use that variable in SET. I don't know ahead of time how many many variables there will be. I've tried things like: FOR %%L IN (%MYSTRING%) DO ECHO %%L but that splits on the equals sign too so I end up with USER Andy IP 1.2

问题 I need to be able to delimit a stream of binary data. I was thinking of using something like the ASCII EOT (End of Transmission) character to do this. However I'm a bit concerned -- how can I know for sure that the particular binary sequence used for this (0b00000100) won't appear in my own binary sequences, thus giving a false positive on delimitation? In other words, how is binary delimiting best handled? EDIT: ...Without using a length header. Sorry guys, should have mentioned this before.

问题 I've to apply the Unix command sed on a string ( can contain #, !, /, ?, &, @ and all other characters ) which can contains all types of character (&, |, !, /, ? ...) Is it a complex delimiter (with two caracters ?) which can permits to outpass the error : sed: -e expression #1, char 22: unknown option to `s' Thanks in advance 回答1: There is no such option for multi-character expression delimiters in sed, but I doubt you need that. The delimiter character should not occur in the pattern , but
