How to Remove Duplicates Values from table

hope this fix your issue Since your screenshot is of phpMyAdmin, I'm going to assume that we're talking about MySQL here (when asking questions, that's helpful information as various SQL dialects have different tools that can be used).
If you don't need id in your results, you can just use DISTINCT:
SELECT
  DISTINCT
    Username,
    Video
FROM
  YourTableName
SELECT
  MIN(id) AS id,
  Username,
  Video
FROM
  YourTableName
GROUP BY
  Username,
  Video
DELETE FROM
  YourTableName
WHERE
  id NOT IN(SELECT MIN(id) FROM YourTableName GROUP BY Username,Video)

delete 
from table
where table.ID NOT IN (
            select MAX(ID)
            from table

How to remove duplicates values and create a table view section in Swift?

will help you I would create another dictionary with a string key (which will be your type) and an array of KempfFiber as the values. Then when you get a type you retrieve the array from the dictionary. If it is nil then create a new array, add the kempf object to it, otherwise just add the kempf object to the existing array. You can then get the keys as an array for your sections.
Something like this (where kempfData and sectionKeys are properties of your current class -
self.kempfData=[String:[KempfFiber]]    

for innerDict in plistArray as Array {
    let kempf: KempfFiber = KempfFiber() // Model
    kempf.name = innerDict["Name"] as String
    kempf.detail = innerDict["Detail"] as String
    kempf.imageName = innerDict["ImageName"] as String
    kempf.specGrav = innerDict["SpecGrav"] as String
    kempf.toughness = innerDict["Toughness"] as String
    kempf.pdfFile = innerDict["PDF"] as String

    var theType = innerDict["Type"] as String     

    var kempfArray=self.kempfData[theType]

    if (kempfArray ==nil) {
        kempfArray =[Kempf]()     
    }

    kempfArray!.append(kempf)
    self.kempfData[theType]= kempfArray

  }

  self.sectionKeys=Array(self.kempfData.keys)
 let sectionData=self.kempfData[self.sectionKeys[indexPath.section]]

 if (sectionData != nil) {
     return sectionData!.count
 }
 else {
     return 0
 }
let sectionData=self.kempfData[self.sectionKeys[indexPath.section]]

if (sectionData != nil) {
     let kempf=sectionData[indexPath.row]
     // Configure your cell...
}
else {
    // Something bad happened
}

This might help you Try this, as per article http://www.dba-oracle.com/t_extract_comma_delimited_strings_oracle_sql.html:
select distinct str from
(select regexp_substr ('ABCD1234, XYZ, ABCD1234, ABCD1234C, ABCD1234, abc, abcX, 1234U, 1234', '[^, ]+',1, rownum) str 
from dual 
connect by level <= regexp_count ('ABCD1234, XYZ, ABCD1234, ABCD1234C, ABCD1234, abc, abcX, 1234U, 1234', '[^, ]+')) v;

MySQL - Select values and remove duplicates by table name


Tag : mysql , By : LinnheCreative

may help you . If I understand correctly, you want to always retain all records from table_saved, plus records from table_default having IDs not appearing in table_saved. One approach is to use a left join to find the unique records from table_default. Then union that with all records from table_saved.
SELECT t1.ID, t1.SOME_VAL
FROM table_default t1
LEFT JOIN table_saved t2
    ON t1.ID = t2.ID
WHERE t2.ID IS NULL
UNION ALL
SELECT ID, SOME_VAL
FROM table_saved;

Remove SOME duplicates in data.table column X, but retain duplicates if column Y matches condition

wish of those help We could create an ordered 'STATUS' based on the levels 'A', 'B', 'C', grouped by 'ID', extract the first present levels (after applying droplevels), do a comparison with 'STATUS' to return logical vector, convert it to a numeric index (.I) also have a condition to check if the number of unique elements in the column is 1, return only the first row
test[test[, .I[if(uniqueN(STATUS) == 1) 1 else 
   STATUS == first(levels(droplevels(ordered(STATUS, 
          levels = c("A", "B", "C")))))], ID]$V1]
#   ID STATUS
#1:  1      B
#2:  2      A
#3:  2      A
#4:  2      A
#5:  2      A
#6:  2      A
#7:  3      C
test <- structure(list(ID = c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 
2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 
3L, 3L, 3L, 3L), STATUS = c("B", "C", "C", "C", "A", "A", "A", 
"A", "A", "B", "B", "B", "B", "B", "C", "C", "C", "C", "C", "C", 
"C", "C", "C", "C", "C", "C", "C", "C", "C", "C")), class = c("data.table", 
"data.frame"), row.names = c(NA, -30L))
