Rename columns contains certain symbol
Hello dear users/experts, I have a table has many columns, where some of the columns are started with "std" (some are not),for example column names could be:std_A, std_AX, med_XA,data_Ex,std_BN.... And i would like to change to A_std, AX_std, med_XA, data_EX, BN_std... only remove std at the begining of column names and put them in the end with _
