c++ - Prepared Statement in MySQL Connector -


i want prepared statement this:

pstmt=conn->preparestatement("update partidos set i?=? id=?"); pstmt->setint(1,lazo); pstmt->setstring(2,texto[lazo]); pstmt->setint(3,var); pstmt->execute();

"lazo" variable in loop, texto[lazo] variable , var int variable.

when run query, throws exception: "you have error in sql syntax; check manual corresponds mysql server version right syntax use near 'i?=? id=?' @ line 1".

it seems doesn't replace '?'.

i tried stringstreams, problem didn't fix.

thanks.

finally opted this.

stringstream stmtvar; stmtvar << "update partidos set minuto" << lazo << "='" << texto[lazo] << "' id=" << var; stmt->executeupdate(stmtvar.str());

it worked perfectly
