( ) -- makes tuple datatype.

2 columns -- select 1,2
desc (select 1,2)
┌─name─┬─type──┬
│ 1    │ UInt8 │
│ 2    │ UInt8 │
└──────┴───────┴

1 column -- select (1,2)    
desc (select (1,2))
─name────────┬─type────────────────┬
 tuple(1, 2) │ Tuple(UInt8, UInt8) │
─────────────┴─────────────────────┴

remove ( ) from your select 

SELECT id, uid, nid, bank, ifsc_code, micr_code, branch, address, 
contact, city, district, state, content, feature_image, var1, var2, var3, 
var4, var5, createdtime, createdtimestr, updatedtime, updatedtimestr,
 status
FROM bankIfsc_bck;
