check for certain characters
hi, I have a field which is a genome sequence and I need to check if each of the entries made for the sequence field contains only a,t,c or g in the string and no other characters. how will i give the query??? thanks, liz -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: check for certain characters
the output of the query should be: all the records that contain even one letter other than a,t,c or g.

It depends. You can find matching values with WHERE col_name REGEXP '^[atcg]+$' but you don't say what you want for output, so beyond that it's difficult to say what the rest of the query should look like. -- Paul DuBois, MySQL Documentation Team Madison, Wisconsin, USA MySQL AB, www.mysql.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
into outfile
hi, when i use the into outfile query in mysql to put the records in a text file, and when i open the file that the records are stored in, i dont see each record on one line. each record is seperated by the square symbol. Is there a way in mysql that i can specify that i need one record per line in the text file???

Re: storing
hi, thanks for the info. I'm not very sure about mysql. but this is what ive got. ive got three tables with data in it.need to save the tables and run it on another machine or rather view the tables and records in another machine. 1. if i use mysqldump query, it will prepare a backup right? and where does is prepare it into??? 2. will all the records also be transfered or only the table structure?? 3. will anything get deleted from my machine where the tables are orignally present?? how to go about mysqldump??

display
hi, I want to know if there is a way to change the display of the mysql query results. itz confusing to see if you have a lot of fields in the table. and if the string is a long string for a particular string there are lot of lines that are being printed.

grant problem!!!
hi, I am having problems with mysql. 1. I downloaded mysql on to my system. 2.installed it 3. ran the server using the command prompt C:\mysql\bin\mysqld --console it gave me the results that i could start using the service. 4. i started mysql on another command prompt. what i am trying to do is i have to enter a huge genome sequence into a field. In order to do tht i have to change the global and session variables in mysql. i can change the session variables but i am not able to change the global variables. I gave the command: set global max_allowed_packet=4; it said: Access denied. You need the SUPER privilege for this operation. Then i created a database genome_db . then at the command promp i typed grant all privileges on genome_db.* to root@localhost identified by ' '; i got the result as: Access denied for user: @'localhost' to database 'genome_db' dont know what to do:( confused plzzz help Liz -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

genome sequence
hi I am trying to enter a genome sequence of length 170 in a table. I have created the table as create table sequence(Seq blob); I am using Python script to enter this sequence into the table. I am getting an error OperationalError: (2006, 'MySQL server has gone away') I am not able to store this sequence into the table. what is wrong???

Foreign Keys
hi, I am new to mysql. I am trying to create tables with foreign key constraints. but the constraintsdoesnt seem to be showing any effect on the table. I am able to add any info in the foreign key table witout the same info in the main table. what is the problem??

Re:Foreign Key
at the mysql prompt i typed show variable like have_innodb; and the value was yes. I saw this in the mailing list and tried it. I am not familiar with Innodb . Do i have to install the Innodb version of Mysql? I have mysql 4.0 version.

Re: Foreign Key
I creates 2 tables create table test1(Ser int(5) primary key,age int(2)) type=InnoDB; create table test2(Serno int(5) references test1(Ser),name varchar(20)) type=InnoDB; I inserted a value in test2 and it accepted. Isnt that wrong? shouldnt it accept only if there is a vlue in the first table? I didnt enter any records in the first table.

inserting huge string
hi, I am using mysql 4.0.14. I have a table where one of the fields has a datatype longblob. What I am trying to do is to enter a genome sequence which has around 175 characters. the file size is about 1.5MB which is well within the longblob size. I am using python to enter the sequence from a file to the database and the while i am running the python program ,the connection to the db is lost. So it takes in only around 103500 characters. I tried changing the variables in mysql,the max_allowed_packet using the following command: set max_allowed_packet=4; I tried changing it to max 4G which is the maximum size for longblob. But it changed to a maximum of 1G. Even is it is 1G, the size of the file i am trying to enter is well within the size of the datatype. I am not sure how to enter this huge string. What should I do?? thanks, liz -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
