1 Nunca cree cuentas MySQL sin contraseñas


2 Los datos no numéricos deben citarse, así que ...

query = $sq1. " WHERE CLI.documento = $datoBuscar";

... debiera ser ...

query = $sq1. " WHERE CLI.documento = '$datoBuscar'";


3 Siempre pruebe las consultas directamente primero, por ejemplo, en el programa cliente mysql ... haga que su script haga eco de $ sql, cópielo y péguelo en el programa cliente mysql, corrija errores


4 Las llamadas a MySQL siempre deben incluir verificaciones de errores, por ejemplo ...

$cn = new mysqli('localhost', 'root', '', 'stecnico') or exit( mysqli_connect_error() );

$rs = $cn->query($query) or exit( $cn->error );
