Solution:
Try with "(CASE WHEN akun LIKE '%51%' THEN 51 ELSE 0 END )"
Notice the double quote to contain the whereRaw
statement.
And to send dynamic data you can try "(CASE WHEN akun LIKE '%".data."%' THEN 51 ELSE 0 END )"
So your query should look like this:
$realisasi=Realisasi::whereRaw("(CASE WHEN akun LIKE '%".$data."%' THEN 51 ELSE 0 END )')
->whereYear('tanggal','2020')
->where('kdsatker','412772')
->groupby('akun')
->get();
MySQL requires the like pattern to be inside single quotes. For more reference: https://dev.mysql.com/doc/refman/8.0/en/pattern-matching.html
