db where var1=x AND var2=y AND var3=q

[Ruud]

I can't figure out how to solve a right query, what do I wrong?

sql query: 
DELETE FROM `tbl_resource` WHERE (`ID_resource`=".$var1."  AND `ID_veld`=".$var2." AND `type_resource`='P') LIMIT 1;

first try:
$db->delete("tbl_resource",
[ "AND", 
["ID_resource","=",$db->result()[0]->ID_papo], 
["ID_veld", "=", $lesblokId ],
["type_resource", "=", "P"]
]);

second try:
$db->delete("tbl_resource",
[ "AND", 
[ "AND",[
["ID_resource","=",$db->result()[0]->ID_papo], 
["ID_veld", "=", $lesblokId ]
], 
["type_resource", "=", "P"]
]
]);
