Re: reg C API from MySQL
Hello Patrick! I am trying to connect COBOL to the MySQL Database. I have used the C API to establish the conection to MySQL. You have quoted that library file mysqlclient.lib is enough. But when I try to test the Connecton using VC++ editor by writing a simpe C Program, the linking of libmysql.lib only produce successdul connection. i.e., mysqlclient.lib not required here. But When I try to Link those two files into the Linker for my COBOL application it wouldn't recognize the methods inside the Libraray file (i.e, mysql_init, mysql_real_connect, mysql_error...) and shows linker errors. Is there any other Library files required the platform I have used is Windows 2k CA REALIA II Workbench 3.0.55 CA REALIA COBOL Compiler 6.0.45 Microsoft 32 Bit incremental compiler 6.00.8168 can you please suggest me...

Problem using the C-API for MySQL Program breakdown after about 1Mio SQL-statements
Hallo,
I apologize for my bad english.
Im desperate about the followwing problem :
I'm using the MySQL C-API for accesssing a database with about 1.2 Mio
SQL-Statemants.
Therefor I make a connect to the database and after that a loop
starts a Subprogram about 1.2 Mio times in which a SQL-statement is sent
to the database. My problem is that the program breaks down after about
1 Mio iterations with a Bus error and Segmentation fault.
If I analyse the core dump with a debugger I get the following statements :
The program breaks down at line :
if (mysql_query(mysql2, abfrage)) {
printf (Fehler bei der Abfrage ! Fehler : %s \n %s \n,
mysql_error(mysql2), abfrage);
exit(1);
Program terminated with signal 10, Bus Error.

I checked the SQL statement which is sent at that time an it is ok
and leads to suitable result.
Does any one have an idea why my program breaks down ?
Greetings,
Daniel
P.S :
Here is my code for accessing the database :
(some code. )

}

Maybe it's a good ideea to increase the value of max_allowed_packet(from

Re: Problem using the C-API for MySQL Program breakdown after about1 Mio SQL-statements
Thanks for your advice.
I tried it with the higher value (3M) but the program broke down
like before.
I increased the other buffer values too after that and am
testing now if this helps.

Problem with C API and mysql
hello everybody.
Ive been working with perl and mysql for some time, but recently i had
to move over
to C and as such i wrote a small test program, just to get to know the
mysql C API.
Well, things didnt go as i thought. i kept getting linking problems
and in the end my test program was limited to the few lines bellow:
#include stdlib.h
#include mysql.h
#include unistd.h
#include stdio.h
int main(){
MYSQL *mysql;
mysql = mysql_init(NULL);
if (mysql == NULL) {
fprintf(stderr,mysql_init() failed (foobar\n);
exit(1);
}
}
+
i compile this with:
gcc -I/usr/local/mysql/include/ -L/usr/local/mysql/lib/ program.c
-lmysqlclient
but i always get the error message:
/usr/local/mysql/lib//libmysqlclient.a(my_compress.o): In function
`my_uncompress':
my_compress.o(.text+0x97): undefined reference to `uncompress'
/usr/local/mysql/lib//libmysqlclient.a(my_compress.o): In function
`my_compress_alloc':
my_compress.o(.text+0x12b): undefined reference to `compress'
collect2: ld returned 1 exit status
doing an nm on libmysqlclient.a does reveal that the compress functions
are there,but
for some reason it wont work.
appriciate any/all help
regards
