Question

I need to copy the value in a column named TEAM from one row into another row. Both rows need to have the same team name. This is my query that doesn’t work:

$query = "UPDATE profiles SET team = (SELECT team FROM profiles WHERE id = '$coach_id') WHERE id = '$player_id'";

I have tried removing single quotes, removing “FROM profiles”, changing value to table.value, tried to give a newdata.clan alias, and I have even tried changing the values to integers instead of parameters. Nothing works, and this is what I get:

Error: You have an error in your SQL

version for the right syntax to use
near ‘WHERE id = ”) WHERE id = ”’ at
line 3

Answer 1

$query1 = "SELECT team FROM profiles WHERE id = '$coach_id'";

/* get the value of the first query and assign it to a variable like $team_name */

$query2 = "UPDATE profiles SET team = '$team_name' WHERE id = '$player_id'";
