how to get integers from mysql

[eleanor]

query.prepare(trUtf8("SELECT browse_caption FROM descriptor_table WHERE id='%1'").arg(integer[m_iIndex+1].toInt()));

query.prepare(trUtf8("SELECT browse_caption FROM descriptor_table WHERE id='%1'").arg(integer[m_iIndex+1].toInt()));

Well I can't prepare the statement only once, because I have to change the argument to the prepend) function. The argument is an integer that should raise by one every time I go through for loop.
