Strip last two characters of a column in MySQL

Question

I have an SQL column where the entries are strings  I need to display those entries after trimming the last two characters  e g  if the entry is 199902345 it should output 1999023   I tried looking into TRIM but looks like it offers to trim only if we know what are the last two characters  But in my case  I don t know what those last two numbers are and they just need to be discarded   So  in short  what MySQL string operation enables to trim the last two characters of a string   I must add that the length of the string is not fixed  It could be 9 characters  11 characters or whatsoever

To select all characters except the last n from a string  or put another way  remove last n characters from a string   use the SUBSTRING and CHAR LENGTH functions together   SELECT col           ANSI Syntax     SUBSTRING col FROM 1 FOR CHAR LENGTH col  - 2  AS col trimmed           MySQL Syntax    SUBSTRING col      1     CHAR LENGTH col  - 2  AS col trimmed FROM tbl   To remove a specific substring from the end of string  use the TRIM function   SELECT col        TRIM TRAILING   php  FROM col  -- index php becomes index -- index txt remains index txt
