Question

Simple question. I have a table Person. I have in it two rows:

1 Joe Doe [e-mail]
2 Vivien Doe [e-mail]

How to write a SOCI statement, which will tell me (return) how many rows I have in my table? (Here, in my example, I have 2 rows).

Answer 1

To get the number of rows in an SQL table use the count(*) function like this:

select count(*) from Person

To be more specific – to get the number into C++ variable use:

int count;
sql << "select count(*) from person", into(count);
