Question

I have the following code in my C++ program:

query_state = mysql_query(connection, "select * from cplpl");

if I want to replace the table name,cplpl, by a variable in my C++ program, how do I do it?

basically, I’ve created

string tblnm="cplpl";

but then if I run

query_state = mysql_query(connection, "select * from tblnm");

it looks for the table tblnm. I tried $tblnm also like you can do in Perl, but that doesn’t work either

Is there a way I can fix this? thx!

EDIT:
If I rewrite this as follows:

string tblnm="test";
string qrycd="select * from " +tblnm;
 query_state = mysql_query(connection, qrycd.c_str());

it works, however, if I want to add a where clause

string qrycd1="where fname like '%Bob%';";

and rewrite the code as

string qrycd="select * from " +tblnm +qrycd1;
 query_state = mysql_query(connection, qrycd.c_str());

I get an error..

This should work:

query_state = mysql_query(connection, ("select * from " + tblnm).c_str());
