Re: How to export data with column names?

[chamila gayan]

you have to use 2 select for do this.
The first select generates the headerline and the second the data.

( SELECT 'FieldA','FieldB','FieldC', ... ) UNION ( SELECT `FieldA`,
`FieldB`, `FieldC`, ... INTO OUTFILE 'D:/data.csv'
FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'  FROM ... ...
GROUP BY `FieldA`, `FieldB`, `FieldC`, ... );

another way is use shell and get a dump. then replace tab with ","

mysql -uuser_name -p  database -e "select * from your_table" > PATH/outfile.txt

Re: udf return column name not value

[chamila gayan]

Thank you for your speedy reply.

I tried on your way. But it gives *error* as "*Dynamic SQL is not allowed in
stored function or trigger*". I'm using *MySql 5* as my sever. How can I
solve that.

thank you

udf return column name not value

[chamila gayan]

CREATE FUNCTION getcolumnvalue(id int,columnname varchar(30))
RETURNS varchar(50) DETERMINISTIC
READS SQL DATA
begin
declare retval varchar(50);
select columnname into retval from user where ID = id ;
return retval;
end;

I want get value of related column but it return column name.
ex:- ('tom' what I want but it return 'name')
plz tell what the wrong of this
