+I had to change grammar, as follows :
+
+PlSqlLexer.g4
+
+all string litterals are changed with normal letters (without quotes), and after, there is definition for letters like :
+
+fragment A: [aA];
+fragment B: [bB];
+fragment C: [cC];
+fragment D: [dD];
+fragment E: [eE];
+fragment F: [fF];
+fragment G: [gG];
+fragment H: [hH];
+fragment I: [iI];
+fragment J: [jJ];
+fragment K: [kK];
+fragment L: [lL];
+fragment M: [mM];
+fragment N: [nN];
+fragment O: [oO];
+fragment P: [pP];
+fragment Q: [qQ];
+fragment R: [rR];
+fragment S: [sS];
+fragment T: [tT];
+fragment U: [uU];
+fragment V: [vV];
+fragment W: [wW];
+fragment X: [xX];
+fragment Y: [yY];
+fragment Z: [zZ];
+
+also, change this :
+
+fragment
+SIMPLE_LETTER
+    : [A-Z]
+    ;
+
+to this :
+
+fragment
+SIMPLE_LETTER
+    : 'a'..'z'
+    | 'A'..'Z'
+    ;
+
+after changing litterals, it's safe to replace next strings (in both, PlSqlLexer.g4 and PlSqlParser.g4)
+
+NULL -> HAMO
+null -> hamo
+
+NAN -> MUJO
+nan -> mujo
+
+OVERFLOW -> HASO
+overflow -> haso
+

+
+Building small c++ library for antlr with just one function 
+
+library is in antlr-library.cpp
+
+compile with command :
+
+g++ -c -I runtime-linux/antlr4-runtime/ -I generated -std=c++11 antlr-library.cpp -o antlr-library.o
+
+make static library with command :
+
+ar rcs antlr-library.a antlr-library.o
+
+-------------------
+
+Note : 
+Should link with runtime library staticly
